To find and confirm the most effective preparing technology, the effect of sintering temperature and calefactive velocity upon mechanical properties and microstructures of the materials before and after infiltration were studied. In order to control the coefficient of thermal expansion and colors of the glass as well as the fluidity and infiltration property of the melted glass, we modified the formula of the glass.

The results show that the composite coating is metallurgically bonded to the substrate and the microstructure is fine and uniform. The hardness of the composite coating is up to 400 HV, which is 2.5 times that of the substrate. Under room temperature and oil lubrication condition, the sliding wear tests indicate the friction coefficient and weight loss of the composite coating are smaller than those of substrate. The worn surface of the composite coatings is much smoother than that of the substrate, without grooves and crater.
