Abstract: A simple hydrothermal method was used to synthesize silver-doped zirconia-reduced graphite oxide (Ag-ZrO2/r-GO) composite coating on CoCrMo, an alloy commonly used in artificial hip joints. The Ag-ZrO2/r-GO coating is mainly intended to extend the service life of artificial hip joints via a rational coating design, which consists of three components, namely, a ceramic component ZrO2, a friction reducing component r-GO, and an antibacterial agent Ag. After hydrothermal treatment in Zr(SO4)(2) center dot 4H(2)O solution containing GO at 200 degrees C for 24 h, ZrO2/r-GO coating of about 12.5 mu m thick was formed on CoCrMo substrate. Ag was incorporated subsequently by soaking in AgNO3 solution and calcination was carried out to improve the adhesion of the coating on CoCrMo substrate.
