Abstract
An abrasive coating and a process for forming the abrasive coating by co-depositing hard particles within a matrix material onto a substrate using a cold spray process. The cold sprayed combination of hard particles and matrix material provides a coating that is wear, erosion and oxidation resistant. The abrasive coating may have different compositions across its depth. The hard particles may be deposited at different densities across the thickness of the matrix material. A first layer of the abrasive coating proximate the surface of the substrate may be devoid of hard particles.
