[0002] Corrosion detection is a chemical experiment, the purpose of which is to detect the material test of the chemical or mechanical-chemical damage process caused by the interaction between metals or other materials and the environment. Corrosion test is an important means to master the characteristics of the corrosion system composed of materials and the environment, understand the corrosion mechanism, and thus control the corrosion process.

[0003] The existing corrosion detection generating device has a relatively simple structure. It only immerses the component sample in a container filled with a corrosion solution. Although it can achieve the purpose of detection, there are still other problems in the use process. For example, it does not have a stress application function. Since this failure mode is sudden, it is not easy to detect if the sample is simply placed in the corrosion solution, and the waiting time required for occurrence is relatively long, and the practicability is low. To solve the above problems, we propose an auxiliary stress corrosion cracking generating device. Content of the Utility Model
