[0045] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0046] The corrosion rate determination method provided in the embodiment of the present application can be applied in the application environment shown in FIG. 1. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. The terminal 102 can measure the initial sample parameters of the sample to be tested for the target material, and determine the data such as the initial surface area, initial weight and initial thickness of the sample to be tested; further, after the corrosion test of the sample to be tested is completed, the terminal 102 again measures the test sample parameters of the sample to be tested after the corrosion test; then, the terminal 102 sends the measured initial sample parameters and test sample parameters to the server 104, and the server 104 calculates and analyzes the initial sample parameters and the test sample parameters, and determines the target corrosion rate of the target material in the actual application environment according to the results of the calculation and analysis. Among them, the terminal 102 can be, but is not limited to, various measuring instruments, high-precision electronic balances, vernier calipers, micrometers and laser rangefinders. The server 104 can be implemented with an independent server or a server cluster consisting of multiple servers.

[0047] In an exemplary embodiment, as shown in FIG2 , a corrosion rate determination method is provided, which is described by taking the method applied to the server 104 in FIG1 as an example, and may include the following steps:

[0048] S201, obtaining initial sample parameters of a sample to be tested of a target material.

[0049] Among them, the initial sample parameters include at least one of the initial surface area, initial weight and initial thickness; the samples to be tested include a first sample to be tested and a second sample to be tested, the first sample to be tested and the second sample to be tested have different shapes, the initial sample parameters of the first sample to be tested include the initial surface area and the initial weight, and the initial sample parameters of the second sample to be tested include the initial thickness, that is, corrosion tests are performed on target materials of different shapes through different test dimensions (i.e., dimensions such as surface area, weight and thickness).

[0050] Exemplarily, in the process of determining the initial surface area parameters by the terminal 102, if the shape of the sample to be tested is regular, the surface area of ​​the sample to be tested can be directly determined by using a formula, such as the surface area of ​​a cube = 6×(side length ^ 2); if the shape of the sample to be tested is irregular, a high-precision scanner or three-dimensional scanning technology can be used to determine the three-dimensional shape of the sample to be tested and determine the surface area; if the sample to be tested is relatively small, a microscope and image processing software can be used to determine the surface area of ​​the sample to be tested; in the process of determining the initial weight parameters by the terminal 102, it can be determined by a high-precision electronic balance and other equipment; in the process of determining the initial thickness parameters by the terminal 102, it can be determined by a vernier caliper, a micrometer, a laser rangefinder, an ultrasonic thickness gauge, a microscope and other equipment; finally, the terminal 102 transmits the determined initial sample parameters, i.e., the initial surface area, initial weight and initial thickness, to the server 104 through the communication module, so that the server 104 can directly obtain the initial sample parameters of the sample to be tested for the target material and determine the data such as the size and structural characteristics of the sample to be tested.

[0051] It should be noted that the initial sample parameters of the sample to be tested are obtained after the sample to be tested is polished, cleaned and dried. Optionally, the surface of the sample to be tested is polished to obtain a uniform surface state; further, the polished sample to be tested is cleaned and then dried to achieve a constant weight of the sample to be tested, and finally the initial sample parameters of the sample to be tested can be accurately obtained.

[0052] S202, obtaining test sample parameters after the sample to be tested is corroded in a corrosion test chamber.

[0053] Among them, the corrosion environment of the corrosion test box is the same as the actual application environment of the target material, that is, by pre-setting parameters such as temperature, humidity, medium composition, medium concentration, gas composition and flow rate in the corrosion test box, the corrosion environment of the corrosion test box is the same as or similar to the actual application environment of the target material.

[0054] Exemplarily, the sample to be tested can be placed at a designated position in a corrosion test box and exposed for a predetermined test duration; wherein, during the test, parameters such as temperature, humidity, medium composition, medium concentration, gas composition and flow rate in the corrosion test box need to be monitored in real time to ensure that they fluctuate within a set range, and to ensure that the corrosion environment of the corrosion test box is the same as or similar to the actual application environment of the target material; further, after the test duration is reached, the terminal 102 measures the sample to be tested after being corroded by the corrosion test box again, and transmits the test sample parameters (such as test surface area, test weight, test thickness and test duration) obtained by the test to the server 104 through the communication module; thereby, the server 104 can directly obtain the test sample parameters of the sample to be tested after being corroded by the corrosion test box.

[0055] S203, determining a target corrosion rate of the target material under an actual application environment according to the initial sample parameters and the test sample parameters.

[0056] Among them, the target corrosion rate can represent the actual corrosion rate of the target material in the actual application environment, and can be used to evaluate the performance such as the service life of the target material in the actual application environment.

[0057] Exemplarily, based on the initial sample parameters and the test sample parameters, the changes in the test samples of the target material within a certain test time can be determined; further, based on the changes in the test samples of the target material within a certain test time and the test time, the target corrosion rate of the target material in the actual application environment can be ultimately determined.

[0058] The above corrosion rate determination method obtains the initial sample parameters of the sample to be tested for the target material, such as the initial surface area, initial weight and initial thickness, to determine the condition of the sample to be tested before the corrosion test; further, the sample to be tested is subjected to a corrosion test, and the test sample parameters of the sample to be tested after being corroded by the corrosion test chamber are obtained to simulate the actual condition of the target material in the actual application environment; and then, the target corrosion rate of the target material in the actual application environment can be determined based on the initial sample parameters and the test sample parameters. This scheme realizes the scenario simulation of the target material in the actual application environment by introducing a corrosion test chamber, perfectly reproduces the actual application scenario, and provides objective conditions for obtaining accurate test sample parameters; furthermore, by analyzing the sample to be tested from three dimensions of surface area, weight and thickness, a data foundation is laid for determining the precise target corrosion rate, and finally the target corrosion rate of the target material in the actual application environment is accurately determined.

[0059] Based on the above embodiment, the present application embodiment explains the above embodiment S202 in detail. Specifically, the process of obtaining the test sample parameters in the present application embodiment, as shown in FIG3, specifically includes the following steps:

[0060] S301, obtaining parameters of a first test sample after the first sample to be tested is corroded in a corrosion test chamber.

[0061] The first test sample parameters include a test surface area, a test weight and a first test duration.

[0062] Exemplarily, the first sample to be tested can be placed at a designated position in a corrosion test box and exposed to a predetermined first test duration; wherein, during the test, parameters such as temperature, humidity, medium composition, medium concentration, gas composition and flow rate in the corrosion test box need to be monitored in real time to ensure that they fluctuate within a set range, and to ensure that the corrosion environment of the corrosion test box is the same or similar to the actual application environment of the target material; further, after reaching the first test duration, the terminal 102 measures the first sample to be tested after being corroded by the corrosion test box again, and transmits the first test sample parameters (i.e., test surface area, test weight and first test duration) obtained by the test to the server 104 through the communication module; thereby, the server 104 can directly obtain the first test sample parameters of the first sample to be tested after being corroded by the corrosion test box.

[0063] S302, obtaining parameters of a second test sample after the second sample to be tested is corroded in a corrosion test chamber.

[0064] The second test sample parameters include test thickness and second test duration.

[0065] Exemplarily, the second sample to be tested can be placed at a designated position in the corrosion test box and exposed according to a predetermined second test duration; wherein, during the test, parameters such as temperature, humidity, medium composition, medium concentration, gas composition and flow rate in the corrosion test box need to be monitored in real time to ensure that they fluctuate within a set range, and to ensure that the corrosion environment of the corrosion test box is the same as or similar to the actual application environment of the target material; further, after the second test duration is reached, the terminal 102 measures the second sample to be tested after being corroded by the corrosion test box again, and transmits the second test sample parameters (i.e., test thickness and second test duration) obtained by the test to the server 104 through the communication module; thereby, the server 104 can directly obtain the second test sample parameters of the second sample to be tested after being corroded by the corrosion test box.

[0066] In an embodiment of the present application, different parameters are obtained for the first sample to be tested and the second sample to be tested, that is, the two dimensions of surface area and weight of the first sample to be tested, and the thickness dimension of the second sample to be tested, so as to evaluate the corrosion rate of the sample to be tested of the target material in the actual application environment from different dimensions, thereby finally obtaining a more accurate target corrosion rate.

[0067] Based on the above embodiment, the present embodiment of the present application explains the above embodiment S203 in detail. Specifically, the process of determining the target corrosion rate in the present embodiment of the present application, as shown in FIG4, specifically includes the following steps:

[0068] S401, determining a first corrosion rate according to an initial surface area, an initial weight and a first test sample parameter of a first sample to be tested.

[0069] The corrosion rate may represent the corrosion rate of the first sample to be tested in the corrosion test box, that is, simulate the corrosion rate of the first sample to be tested in the actual application environment.

[0070] One possible implementation method is to determine the area difference between the initial surface area and the test surface area of ​​the first sample to be tested, and the weight difference between the initial weight and the test weight of the first sample to be tested; determine a first ratio between the weight difference and the area difference; and determine a first corrosion rate based on the ratio between the first ratio and the first test duration.

[0071] Exemplarily, the initial surface area of ​​the first sample to be tested is S0, and the test surface area in the first test sample parameter of the first sample to be tested is S, then the area difference ΔS between the initial surface area S0 of the first sample to be tested and the test surface area S can be expressed as ΔS=S0-S; and the initial weight of the first sample to be tested is M0, and the test weight in the first test sample parameter of the first sample to be tested is M, then the weight difference ΔM between the initial weight M0 of the first sample to be tested and the test weight M can be expressed as ΔM=M0-M; further, the first ratio R can be determined according to the weight difference ΔM and the area difference ΔS, that is, R=ΔM / ΔS; further, the first corrosion rate V1 can be determined based on the first ratio R and the first test time T1, that is, V1=R / T1.

[0072] Another possible implementation method is to directly input the initial surface area S0, initial weight M0 and first test sample parameters of the first sample to be tested into the first rate determination model, which calculates and analyzes them and ultimately determines the first corrosion rate V1 of the first sample to be tested.

[0073] S402, determining a second corrosion rate according to an initial thickness of a second sample to be tested and a second test sample parameter.

[0074] The second corrosion rate may represent the corrosion rate of the second sample to be tested in the corrosion test box, that is, simulates the corrosion rate of the second sample to be tested in an actual application environment.

[0075] One achievable method is to determine the thickness difference between the initial thickness and the test thickness of the second sample to be tested; and determine the second corrosion rate according to the ratio between the thickness difference and the second test duration.

[0076] Exemplarily, the initial thickness of the second sample to be tested is A0, and the test thickness in the second test sample parameters of the second sample to be tested is A, then the thickness difference ΔA between the initial thickness A0 of the second sample to be tested and the test thickness A can be expressed as ΔA=A0-A; furthermore, the second corrosion rate V2 can be determined based on the thickness difference ΔA and the second test time T2, that is, V2=ΔA / T2.

[0077] Another possible implementation method is to directly input the initial thickness A0 of the second sample to be tested and the second test sample parameters into the second rate determination model, which will calculate and analyze them and ultimately determine the second corrosion rate V2 of the second sample to be tested.

[0078] S403, determining a target corrosion rate of the target material under an actual application environment according to the first corrosion rate and the second corrosion rate.

[0079] As in the above example, the first corrosion rate V1 and the second corrosion rate V2 may be averaged to determine the target corrosion rate V of the target material in the actual application environment, ie, V=(V1+V2) / 2.

[0080] In an embodiment of the present application, a first corrosion rate is determined based on two dimensional data of surface area and weight of the first sample to be tested, and a second corrosion rate is determined based on the thickness dimensional data of the second sample to be tested, and finally a target corrosion rate is determined based on the first corrosion rate and the second corrosion rate, thereby achieving a multi-dimensional evaluation of the corrosion rate of the sample to be tested for the target material in the actual application environment.

[0081] Based on the above embodiment, this embodiment provides an optional example of a method for determining a corrosion rate. As shown in FIG5 , the specific implementation process is as follows:

[0082] S501, obtaining initial sample parameters of a sample to be tested of a target material.

[0083] Among them, the initial sample parameters include at least one of the initial surface area, initial weight and initial thickness; the samples to be tested include a first sample to be tested and a second sample to be tested, the first sample to be tested and the second sample to be tested have different shapes, the initial sample parameters of the first sample to be tested include the initial surface area and initial weight, and the initial sample parameters of the second sample to be tested include the initial thickness.

[0084] It should be noted that after the sample to be tested is polished, cleaned and dried, the initial sample parameters of the sample to be tested are obtained.

[0085] S502, obtaining parameters of a first test sample after the first sample to be tested is corroded in a corrosion test chamber.

[0086] Among them, the first test sample parameters include test surface area, test weight and first test duration; the corrosion environment of the corrosion test box is the same as the actual application environment of the target material.

[0087] S503, obtaining parameters of a second test sample after the second sample to be tested is corroded in a corrosion test chamber.

[0088] The second test sample parameters include test thickness and second test duration.

[0089] S504, determining an area difference between an initial surface area of ​​the first sample to be tested and a test surface area, and a weight difference between an initial weight of the first sample to be tested and a test weight.

[0090] S505, determining a first ratio between the weight difference and the area difference.

[0091] S506: Determine a first corrosion rate according to a ratio between the first ratio and the first test duration.

[0092] S507, determining a thickness difference between an initial thickness and a test thickness of the second sample to be tested.

[0094] S509: Determine a target corrosion rate of the target material under an actual application environment according to the first corrosion rate and the second corrosion rate.

[0095] The specific process of S501-S509 can refer to the description of the above method embodiment, and its implementation principle and technical effect are similar, which will not be repeated here.

[0096] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders.
