摘 要：The effects of surface adsorption of bovine serum albumin（BSA） and human gamma-globulin（HGG） on the tribological performance of a DLC film were investigated using a quartz crystal microbalance with dissipation（QCM-D）, a ball-on-disk reciprocating tribometer, and a three-electrode electrochemical cell. The results showed that the wear depth in the BSA solution was higher than that in the HGG solution. In the HGG solution, the HGG-adsorbed layer could act as a lubricating layer and protect the DLC film from wear. The wear volume of DLC film in BSA and HGG mixture solution was higher than that in single HGG solution. This may be because the BSA molecules inhibit the formation of HGG adsorbed layer during sliding.
