Abstract
For an example of brass material-Muntz alloy, the present work compared the microstructures and properties, such as, ceramic deposition efficiency, surface morphology, phase, microhardness, electrochemical behaviour and thermal property, of two kinds of brass-based composite coatings reinforced with SiC and Al2O3 by cold-spray additive-manufacturing. A potential application in repairing the Muntz component was implemented, and the restoration quality was assessed by the interfacial microstructure and tribological performance. In particular, cold spray was proved to be a suitable method of additive manufacturing the easily oxidized and vaporized material and repairing its component.
