As nonmetallic materials, diamond has high interfacial energy with metallic surfaces, resulting in low coherence. Electroless nickel-tungsten-phosphorus plating and subsequent iron-tungsten alloy electroplating on diamond surface were adopted. The morphology and composition of the obtained deposits were analyzed by means of SEM and X-ray diffraction, with results that tungsten which is a carbide-forming element reacted with carbon atoms of the diamond surface, and coherence between diamond and metal surface was enhanced. Defective deposits were investigated and method of prevention has been proposed.
