Description

Technical Field

[0001] The present application relates to the field of material performance testing or other related fields, and specifically, to a system and method for detecting hydrogen embrittlement sensitivity. Background Art

[0002] As a clean and efficient energy source, hydrogen energy has attracted much attention due to its environmental protection characteristics, high energy density and renewability. In the fields of industry, transportation and energy storage, hydrogen energy has broad application prospects, especially high-pressure hydrogen storage and transportation technology, which is crucial to the long-distance and large-scale utilization of hydrogen energy. However, the development, utilization, production, transportation and storage of hydrogen have brought new challenges to materials, one of the most prominent problems of which is the hydrogen embrittlement of hydrogen-exposed materials.

[0003] Hydrogen embrittlement, also known as hydrogen-induced cracking or hydrogen damage, refers to the process in which the mechanical properties, especially the plasticity, of metal materials decrease significantly in a hydrogen environment, and even cause the material to crack or be damaged. The small size of hydrogen atoms allows them to penetrate into the gaps in the metal lattice. As the hydrogen concentration increases, hydrogen atoms gather at material defects to form hydrogen molecules, which generate internal pressure and eventually cause the material to become embrittled or even crack. This phenomenon severely limits the application of hydrogen energy in high-pressure hydrogen storage equipment. Therefore, accurate testing and evaluation of the hydrogen embrittlement sensitivity of materials is crucial to ensure the safety and reliability of hydrogen energy systems. However, there is a lack of unified and clear methods for testing materials in high-pressure hydrogen environments, resulting in a lack of scientific basis for the evaluation of material hydrogen embrittlement sensitivity, which also increases the potential safety risks of hydrogen energy equipment.

[0029] The present invention is described below in conjunction with preferred implementation steps. Figure 1 is a schematic diagram of a hydrogen embrittlement sensitivity detection system provided according to an embodiment of the present application, such as Figure 1 As shown, the system includes:

[0030] The gas supply system 101 is connected to the hydrogen embrittlement detection platform 102. The gas supply system 101 includes a booster pump. The gas supply system 101 is used to obtain a low-pressure gas source, transmit the low-pressure gas source to the booster pump for pressurization, obtain pressurized test gas, and provide the pressurized test gas to the hydrogen embrittlement detection platform 102, wherein the low-pressure gas source includes one of the following: helium and nitrogen.

[0031] Specifically, the low-pressure gas source can be an inert gas or hydrogen. In order to realize hydrogen embrittlement detection of hydrogen-absorbent materials, the hydrogen-absorbent materials can be placed in a hydrogen-absorbent environment or an inert gas environment, and then the hydrogen embrittlement sensitivity of the above-mentioned materials can be determined according to the pressure difference in different environments. In order to make the hydrogen-absorbent materials be in different gas environments, the gas supply system 101 can be used to pressurize the low-pressure gas source through a 150MPa booster pump, thereby providing test gas for the hydrogen embrittlement detection platform 102.

[0032] The hydrogen embrittlement detection platform 102 is used to perform hydrogen embrittlement sensitivity detection on the material to be detected using pressurized test gas to obtain a hydrogen embrittlement sensitivity coefficient.

[0033] It should be noted that the material to be tested refers to hydrogen-prone materials. The hydrogen embrittlement detection platform 102, as the main body in the detection system, can increase the pressure difference to cause the material to be tested to explode due to the different air pressures on both sides, thereby realizing the detection of hydrogen embrittlement sensitivity.

[0034] Specifically, hydrogen embrittlement sensitivity can be determined by the pressure difference method. A specific pressure can be applied on both sides of the material to be tested, wherein the pressure on one side of the material is maintained under the above-mentioned specific pressure conditions and is used as the constant pressure side, and the other side is gas-pressurized at different pressurization rates and is used as the pressurized side until the material to be tested bursts or ruptures.

[0035] Since the platform in the hydrogen embrittlement detection platform 102 is a fixed space, as the material to be detected is deformed, the space on both sides of the material to be detected changes. The constant pressure side is squeezed and deformed, and the space is reduced. It is necessary to control the pressure and properly exhaust the air to ensure the constant pressure on the constant pressure side. The material on the boost side swells and the space becomes larger.

In addition, the high-pressure buffer tank can also withstand higher pressure to avoid gas leakage or excessive pressure causing equipment damage.

[0047] At the same time, the second monitoring and control system is responsible for monitoring and adjusting the pressure data on the other side of the material to be tested to maintain the pressure balance on both sides of the material to be tested, thereby ensuring the accuracy and reliability of the test results. Through the synergy of these two monitoring and control systems, the pressure state of the material to be tested can be effectively controlled to ensure the accuracy and reliability of the test.

The exhaust gas in the platform can be discharged in time through the vent pipe and the ventilation port to ensure the accuracy and reliability of the detection.

[0052] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0053] This embodiment also provides a hydrogen embrittlement sensitivity detection system. Figure 2 is a schematic diagram of an optional hydrogen embrittlement sensitivity detection system provided according to an embodiment of the present application, Figure 3 is a schematic diagram of a hydrogen embrittlement detection platform provided according to an embodiment of the present application, such as Figure 2 , Figure 3 As shown in the figure, the system consists of three parts: gas supply system, monitoring and control system and hydrogen embrittlement detection platform.

[0067] Optionally, in the hydrogen embrittlement sensitivity detection method provided in the embodiment of the present application, determining the hydrogen embrittlement sensitivity coefficient according to the constant pressure data and N variable pressure data includes: for a boost rate value, calculating the ratio of the variable pressure data associated with the boost rate value to the constant pressure data, and obtaining a corrected bursting pressure value; obtaining the bursting time period data associated with each boost rate value, calculating the ratio of the corrected bursting pressure value associated with each boost rate value and the bursting time period data associated with each boost rate value, and obtaining N average boost rate values, wherein the bursting time period data refers to the time period from the time when the material to be detected is pressurized to the time when the material to be detected undergoes a bursting phenomenon; performing linear regression processing on the N average boost rate values ​​to obtain a bursting pressure calculation value; obtaining Y preset pressure calculation values, calculating the ratio of the bursting pressure calculation value to each preset pressure calculation value, and obtaining Y pressure ratios, and taking the maximum value of the Y pressure ratios as the hydrogen embrittlement sensitivity coefficient, wherein each preset pressure calculation value refers to a bursting pressure calculation value of the material to be detected in a hydrogen environment.

[0068] Specifically, when determining the hydrogen embrittlement sensitivity coefficient, since the pressure data on both sides of the material to be tested are different, the ratio of the changing pressure data on the pressure-increasing side to the constant pressure data on the constant pressure side under a certain pressure-increasing rate value can be calculated first, and then the corrected bursting pressure value can be obtained, which can be calculated by the following formula: P' u =0.75*P u / em, where P' u Indicates the corrected burst pressure value, P u represents variable pressure data, and em represents constant pressure data.

Furthermore, the average boost rate value associated with all boost rate values ​​can be subjected to linear regression processing to obtain the calculated blasting pressure value, that is, the calculated blasting pressure value P' can be obtained by the following formula: uHe :P' uHe =a+blgU, where a represents the regression constant and b represents the regression coefficient.

[0070] After obtaining the average pressure increase rate value U calculated under multiple hydrogen environments, these data are subjected to linear regression calculation to obtain the corresponding preset pressure calculation value, and then the ratio of the burst pressure calculation value to each preset pressure calculation value is calculated to obtain the pressure ratio, and finally the maximum value of the above pressure ratio is used as the hydrogen embrittlement sensitivity coefficient. In this embodiment, the hydrogen embrittlement sensitivity coefficient can be determined by comparison with the preset pressure calculation value, so as to more accurately evaluate the blasting performance of the material.
