Abstract

In this study, AI6061 coating was deposited on AZ31B magnesium by cold spray with a commercially AI6061 powder blended with large sized stainless steel particles (as shot-peehing particles for in-situ shot-peening assited densifying of the coating) using nitrogen gases at low working gas pressure and temperature. Powders and coatings were characterized by scanning electron microscopy and microhardness measurements. It was found that through introducing the in-situ tamping effect by using shot-peening (SP) particles, the plastic deformation of deposited particles is significantly enhanced, thereby resulting in a dense AI6061 coating. SEM observations revealed that no SP particle was incorporated into AI6061 coating. The effect of SP particles on the deposition efficiency of AI6061 particles was also examined. The electrochemical corrosion experiments revealed that using the novel in-situ shot-peening assisted cold spraying it is possible to deposit fully dense AI6061 coating which can provide complete protection for the magnesium materials from corrosion.
