Inconel 713C Coating by Cold Spray for Surface Enhancement of Inconel 718

Inconel 713C is a nickel-based superalloy usually considered as material of poor weldability due to its susceptibility hot cracking in the heat-affected zones. Cold spray, solid-state deposition technology that does not involve melting, can be proposed methodology deposit for surface enhancement other target components. In this study, coating was deposited on 718 substrate with high-pressure cold spray system. The characterized terms microstructure, hardness, and wear properties. cold-sprayed has low porosity level refined grain structures. Microhardness much higher than substrate. sliding tests showed resistance three times substrate, making suitable protective layer. main mechanisms include oxidation, tribo-film formation, adhesive wear.
