Corrosion test: salt spray test + humidity test

Corrosion testing includes salt spray testing and humidity testing. Metal corrosion testing helps determine the susceptibility of materials to corrosion.

Corrosion testing also includes comparing the wear of different materials, evaluating the effectiveness of protective treatments, and identifying corrosion-causing materials.

Metal corrosion testing helps determine a material's strength and ability to withstand different environmental conditions. Since natural corrosion processes can be slow, many accelerated testing methods exist to predict corrosion behavior. A simple way to perform a corrosion test is to expose a sample of the material to environmental factors for a period of time and then evaluate the corrosion that has occurred.

Taking metal rust as an example, the damage caused by rust to metal is obvious to all. As industries develop, such as electroplating on metals, some electroplating processes help stop rust under salt spray testing.

In addition to the salt spray test, there is also a cyclic corrosion test, which is better than the traditional salt spray test for evaluating conditions such as crevice corrosion.
