Problems solved by technology

Today, with the rapid development of new materials, the corrosion test in the natural environment is difficult to meet the needs of quickly and accurately evaluating the corrosion resistance of materials. Therefore, in general, this test is only carried out on some conventional materials to provide the necessary basic corrosion data for theoretical research.

Embodiment Construction

[0044] A non-destructive monitoring and testing method for simulating accelerated corrosion of materials in a marine environment, the flow chart of which is shown in figure 1 shown. The realization of this method requires the synergistic effect of the accelerated corrosion test module for simulating the marine environment and the non-destructive monitoring and detection module for corrosion potential.

[0045] The corrosion acceleration test module simulates the marine atmosphere area, splash area, tidal range area, full immersion area and sea mud area in different sea areas by controlling the propeller speed, temperature, humidity, pH value, light, precipitation and other factors. According to the sea environment that needs to be simulated, the required motor speed is calculated through the formula of "International Wave Level Table". When the working environment of the test material is in slight waves or small waves, the motor speed is not high at this time, and the sample ...

Abstract

The invention relates to a test method for lossless monitoring and detection for the material accelerated corrosion under a simulated marine environment, which comprises a corrosion accelerating test under the simulated marine environment and a test for the lossless monitoring and detection for the corrosion potential of material, wherein the corrosion accelerating test under the simulated marine environment is performed on a corrosion accelerating module, which can be used for finishing the tests for the marine or industrial atmospheric corrosion, splashed spoondrift corrosion, tidal range corrosion, full-soaking corrosion and sea mud microbiological corrosion. The test for the lossless monitoring and detection for the corrosion potential of material is finished by using a corrosion potential lossless monitoring and detection module. The method provided by the invention has the advantages that an environment for simulating each corrosion area in the ocean is supplied, the test period is shortened by performing the corrosion accelerating test, and the corrosion degree of the material is monitored and detected in the whole process. The method is used for supplying a technical support for evaluating the corrosion resistance of the material under the marine environment, thereby shortening the period of researching and testing the material.

Description

technical field [0001] The invention belongs to the technical field of material corrosion, and specifically relates to a test method for accelerating material corrosion in a simulated marine environment and implementing non-destructive monitoring and detection. Background technique [0002] Seawater is a strong electrolyte solution containing a variety of salts, and steel structures are easily corroded under such conditions. Therefore, people devote themselves to the research of various anti-corrosion materials, hoping to reduce the loss caused by corrosion. At present, the assessment of material performance generally includes natural environment corrosion test and laboratory corrosion test. Corrosion tests in natural environments can truly reflect the corrosion status and laws of materials. However, the test period is generally long, the cost is relatively high, and it is difficult to monitor the corrosion state in real time. Today, with the rapid development of new mate...
