Abstract
A method of improving adhesion of a nickel alloy to the surfaces of diamond particles and articles made therefrom. Diamond particles are electrolessly nickel plating with the nickel alloy formed with a transitional metal, such as molybdenum. Electrolessly plated particles are then gradually heated at a steady rate from room temperature to a desired heat treatment temperature in a non-oxidizing atmosphere formed by argon containing 10% hydrogen. Exemplary articles made by the aforementioned process include a grinding wheel having uniformly dispersed abrasive diamond particles having the Ni/Mo alloy coat thereon.
