The present invention addresses problems in the diamond saw blade and segment art. One aspect of the invention comprises a method for making handleable, strong, discrete, metal-clad abrasive pellets. This method comprises the steps of:

Diamond pellets and saw blade segments made therewith

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.

Multi-layer metal coated diamond abrasives for sintered metal bonded

Multi-layer coated diamond abrasive particles having improved wear performance in abrasive tools 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 applied by electroless deposition, preferably comprised of nickel/phosphorus or cobalt/phosphorus.
