Abstract: The environmental protection policies promoted the chromium-free development of anti-corrosion coatings for metal components in automobile，ship，bridge and other industries. The development of green，environment friendly，and energy-savingchromium-free zinc-aluminum coatings had become an important technical topic in variousindustries. This paper focused on the current research progress and application of chromium-free zinc-aluminum coatings. The anti-corrosion mechanism of chromium-free zinc-aluminum coatings，the main types of chromium-free film forming passivators，and the research progress of nano material modified zinc-aluminum coatings were summarized. It analyzed the current application status and prospects of chromium-free zinc-aluminumcoatings in fields such as automobile，ships，and bridges，and proposed the research method problems of chromium-free zinc-aluminum coatings，it was expected to provide reference forthe development and promotion of new chromium-free zinc-aluminum coatings.
