Corrosion protection of magnesium alloys by cold spray

Corrosion protection by cold spray is a method by which thick aluminum coatings can be directly and locally applied to magnesium alloys to reduce or eliminate general or galvanic corrosion. Cold spray technology is based on the fact that every metal displays a temperature-dependent critical particle velocity above which the particles bond to the substrate. The method is capable of producing thick coatings that exhibit extremely low porosity …
