Using electrospark alloying machine, a series of experiments were carried out to investigate the effect of electrospark surface strengthening process on the microstructure and the properties of the coatings with ultrafine cemented carbide as electrode material and white cast iron as substrate material. The results indicated that the optimum process parameters to be used reached a satisfying coating surface. Wear test results showed the coatings had a high wear-resistance.
