In order to study the corrosion phenomenon of automotive metals in the actual environment and different test methods, Zinc materials is selected as the research object. The corrosion phenomenon of Zinc plate in atmospheric environment, NSS neutral salt spray test and CCT cycle corrosion test are analyzed through the dimensions of corrosion morphology, weight loss and electrochemical corrosion analysis, and the corrosion fitting matrix of zinc material is obtained. The material corrosion characteristics under different corrosion atmosphere conditions are quantitatively analyzed, which provides a reference for exploring automobile intelligent evaluation methods, shortening corrosion test cycle and accelerating corrosion verification progress.
