        Corrosion resistance test is a material test that detects the chemical or physical (or mechanical)-chemical damage process caused by the interaction of metals and other materials with the environment. It is an important means to grasp the characteristics of the corrosion system composed of materials and environment, understand the corrosion mechanism, and thus control the corrosion process.
