Abstract
Multi-layer coated diamond abrasive particles which exhibit good retention in abrasive tools and are simpler to manufacture are provided, wherein the coating comprises a single homogenous, carbide forming metal primary layer, preferably of chromium, and at least one non-carbide forming secondary layer, preferably of nickel, iron, cobalt, or alloys thereof. The primary layer is preferably applied so as to chemically bond to the surface of the diamond abrasive particles without sintering following deposition by using chemical vapor deposition or packed salt bath deposition.
