Development of WC-based metal matrix composite coatings using low-pressure cold gas dynamic spraying

► Mixed WC and Ni powder to form various compositions of mechanical blends. ► Fabricated WC-based metal matrix composite coatings using low-pressure cold-spray. ► Increased amount of WC particles in the coating improved coating hardness. ► Coating hardness was explained using mean free path and rule of mixtures method. ► Low temperature prevented decarburization of the WC particles.
