A method of improving adhesion of a nickel alloy to the surfaces of diamond particles and articles made therefrom comprises electrolessly nickel plating with a nickel alloy formed with a transitional metal, such as molybdenum, titanium, niobium and chromium,gradually heating at a steady rate from room temperature to a desired heat treatment temperature in a non-oxidizing atmosphere formed for example by argon containing 10% hydrogen. Articles made by the aforementioned process include grinding wheels having uniformly dispersed abrasive diamond particles having a Ni/Mo alloy coat thereon and printed circuit boards.
