Abstract
A method of functionalizing a diamond crystal comprises hydrogenating a diamond crystal, chlorinating the hydrogenated diamond crystal; and exposing the chlorinated diamond crystal to a metal precursor. The exposing step deposits a layer of metal on surfaces of the diamond crystals. The diamond crystal formed by the method possesses surface sites that form a strong bond with the layer of metal to prevent separation thereat, and the layer of metal form strong bonds to a matrix material, for example one of a vitreous and metallic matrix. The functionalized diamond crystal can be used in abrasive products.
