Tailoring the residual stress during two-step cold gas spraying and friction-stir surface integration of titanium coating

In this article, a novel processing route combining cold gas spraying (CGS) and friction-stir processing (FSP) was employed to fabricate a dense titanium surface coating with high integrity and superior mechanical property. After subsequent implementation of CGS and FSP processes, a coating layer wi...
