Description

Technical Field

[0001] The utility model relates to the field of metal corrosion, and specifically relates to an accelerated corrosion device for metal materials under a simulated marine environment. Background Technique

[0002] At present, in order to simulate the influence of the marine environment on metal materials, indoor accelerated corrosion test methods are widely used. Among them, the neutral salt spray test is a commonly used method. However, due to the lack of clear standards for the salt content of the solution, the control of the simulated environmental temperature and humidity, and the selection of the acceleration period, the validity of the experimental data of this method is questionable and it is difficult to be used for research analysis and result induction and comparison. In addition, there are other defects and deficiencies in traditional accelerated corrosion schemes, such as the corrosion degree on the surface of metal materials not meeting the requirements of the actual marine environment and the degradation of performance indicators not being obvious.

[0003] On the other hand, although the test methods of hanging specimens in the actual sea or exposing them to the marine atmospheric environment can more realistically reflect the corrosion effect of metal materials, due to the influence of various environmental media and human subjective factors, there may be deficiencies in the final result analysis and the understanding of the damage mechanism, and it is difficult to guarantee the accuracy of the research method. In addition, this method may also lead to a relatively large difference in the corrosion results of various material products under the same test environmental conditions, and the main influencing factors of material corrosion damage are not clear.

[0004] In summary, there are many difficulties in simulating the corrosion development process under the marine environment by traditional test methods, and it is impossible to effectively grasp the main control factors. Content of the Utility Model
