Abstract: In order to meet the demand for the lightweight design of stage structures in seawater environments, this study focuses on the corrosion and wear properties of amorphous coatings on the surface of magnesium alloys.Through the analysis of the corrosion and wear problems faced by magnesium alloys in the application of stage structures, an Fe-based amorphous coating was deposited on the surface of AZ31 magnesium alloy by explosion spraying.The corrosion and wear mechanisms of the coating were investigated.The results show that the Fe-based amorphous coating has not undergone obvious crystallization and has a high content of the amorphous phase.Compared with the bare magnesium alloy substrate, the self-corrosion current density of the sample surface after coating deposition is reduced by a factor of 6.6, the hardness is increased by 12 times, and the wear resistance is enhanced by 144 times.The lamellar interface of the coating is a weak point for corrosion and wear, and the wear mechanism of the coating is fatigue delamination wear and oxidative wear.This study provides key technical support and a theoretical basis for the widespread application of magnesium alloys in the lightweight design of stage structures.
