Suman Shrestha makes a preliminary evaluation of aluminium, copper and 316L stainless steel coatings prepared using the cold spray process
Cold spraying is a new process for depositing metals and their alloys as coatings without having to subject the spray particles or substrate to high temperatures. This avoids thermal degradation, evaporation or oxidation. Cold spray particles do not melt but deform on impact. The range of materials using the cold spray process is increasing and currently includes aluminium, copper, nickel, titanium and their alloys as well as some stainless steels.
To determine the microstructural characteristics such as porosity and oxide content and the adhesion of cold sprayed copper, aluminium and 316L stainless steel coatings.
