Coating adhesion is a critical factor in cold spray. Generally, particle impact velocity is a dominant factor of cold sprayed coating property, in addition, particle velocity heavily depend on spray angle. In this study, experiment was conducted to investigate the effect of spray angle, substrate hardness and surface roughness on copper coating adhesion strength and bonding morphology of individual copper particles. Spray angle is varied to six different levels: 30, 45, 50, 60, 75 and 90 degree. Used substrate materials are mirrored or blasted mild steel and aluminum alloy. The result shows that copper coating adhesion strength on mirrored steel substrate is increase with a decrease in spray angle. Deposition morphology of copper particles is vary depends on spray angle.
