Research on the Impact of China Atmospheric Environment and Road Conditions on Automotive Corrosion
This paper analyzes and summarizes the impact of China's natural environment,industrial atmospheric environment and road conditions on the occurrence and acceleration of corrosion in automotive metal materials.The results show that temperature,relative humidity,soil acidity and alkalinity,salt spray in coastal areas,road deicing salt,and industrial atmospheric pollutants are key factors that induce and accelerate the corrosion of vehicle bodies and components.Therefore,in automotive development,rational anti-corrosion design should be made based on these key factors,and corresponding corrosion verification methods should be established to improve the compatibility between the anti-corrosion performance of vehicles and their actual corrosion life,thereby reducing quality issues and cost waste telated to anti-corrosion.
