Abstract

A facile and environment-friendly strategy is proposed to prepare dense, thin and antioxidant aluminum coatings on LA43M magnesium alloy via cold spraying and subsequent shot peening technologies. High-energy martensitic stainless steel particles are used to tamp the cold-sprayed coatings, which resulted in complete plastic deformation of Al particles and elimination of pores. The samples with shot-peened Al coating showed excellent corrosion resistance in electrochemical tests. Moreover, long-term salt spray and immersion test revealed that the shot-peened Al coating can effectively protect LA43M alloy from corrosion. Shot-peened Al coating offered promising and long term applications time in the harsh environment.
