ABSTRACT:
A method of improving adhesion of a nickel alloy to the surfaces of cubic boron nitride particles and articles made therefrom. Cubic boron nitride particles are electrolessly nickel plated with the nickel alloy formed with the metalloid, such as boron. 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 cubic boron nitride particles having the Ni/B alloy coat thereon.
