GO-Al2O3 hybrid material was prepared to enhance the bond strength between GO and chemically bonded ceramic coating (CBCC). TEM and FTIR results indicate that nano Al2O3 is successfully grafted to the surface of GO via chemical bonds. Besides, the tribological behavior of CBCC with GO-Al2O3 hybrid material was investigated. The results show that the friction coefficient and wear rate of CBCC decrease with the introduction of GO-Al2O3 hybrid material. In addition, the formation of debris becomes difficult as the cohesive strength of CBCC increases with the introduction of GO-Al2O3 hybrid material, which can improve the wear resistance of CBCC. Furthermore, because less debris on the worn surface makes bigger real contact surface against the counter ball than that of CBCC without GO-Al2O3 hybrid material, the contact stress obviously decreases, contributing to high wear resistance.
