The atmosphere contains corrosive components and factors such as oxygen, humidity, temperature changes, and pollutants. The atmospheric environment causes a water film to form on the metal surface. In the atmosphere, harmful gases such as nitrogen, nitrogen, and nitrogen dissolve into the water film formed on the metal surface and act as corrosive ions to accelerate the corrosion process.
Under a certain temperature and humidity environment, harmful gases such as , , and N are used to accelerate corrosion of materials or products, and reproduce the degree of damage suffered by materials or products within a certain time range. Assessment of the gas corrosion resistance of materials and protective layers, and comparison of process quality of similar protective layers, can also be used to assess the gas corrosion resistance of certain products.
