Abstract
Diamond particles are coated with a Ti metal to form Ti metal coated diamond particles product by contacting the diamond particles with an alloy of the following composition, Ti(1−x)Crx, where 0.05<x<0.5, at a temperature of less than about 850° C. and for a time sufficient for the alloy to coat the diamond particles. The resulting coated diamond particles have an average particle size ranging from about 5 to 800 μm and are coated with metal coating composed of an inner carbide layer enriched in Cr content and an outer layer depleted in Cr content.
Claims17
