Abstract
Ceramic particles useful as abrasives in a metal matrix layer are described. The particles are coated with an oxide monolayer and a metal duplex layer. Preferably, the particles are silicon carbide; the oxide monolayer is aluminum oxide, and the metal duplex layer is a nickel-boron alloy over pure nickel.
