What is Corrosion Test, What Testing Items are There
January 10, 2022
Corrosion testing machine，Corrosion testing, material testing for the detection of chemical or physical (or mechanical)-chemical damage to metals or other materials due to their interaction with the environment.
Corrosion test is an important means to master the characteristics of the corrosion system composed of materials and environment, understand the corrosion mechanism, and thus control the corrosion process.
① Determine the suitability of various anti-corrosion measures in a given environment, the best choice, quality control methods and the expected service life of components after these measures are taken;
②Evaluate the corrosion resistance of the material;
③ Determine the corrosiveness of the environment, and study the effects of impurities and additives in the environment on the corrosion rate and corrosion form;
④ Study the pollution effect of corrosion products on the environment;
⑤ Carry out reproducibility test when analyzing the cause of component failure;
⑥ Study the corrosion mechanism.
Corrosion Test Detection
Salt spray corrosion test
The salt spray test is a comprehensive salt spray test, which is actually a neutral salt spray test plus a constant damp heat test.
Gas Corrosion Test

The gas corrosion test is used to determine the suitability of the product for operation and storage in the atmosphere, especially the contacting and connecting parts. The main factors affecting corrosion are temperature and humidity, atmospheric corrosive elements, etc.
