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.　©　2020　Elsevier　B.V.
