The surface image and inner structure of electroless Ni-P-B 4 C deposit layers were observed and analyzed by SEM, optical microscope and X-ray diffractometer. The results showed that with increase of the amount of B 4 C particles in the plating solution, the number of the surface nodular protrusions increased. The particles of B 4 C evenly dispersed on the Ni-P matrix and adhered well in the coatings. The presence of the B 4 C particles does not change the phase composition. The mechanical properties of composite coatings were measured. The results indicated that with increase of the content of B 4 C, the hardness and wear resistance were obviously improved, but the critical load was decreased.read more
