Abstract
The poor tribological performances of titanium alloy as bone implants has important influence on its implantation failure. In this investigation, nitrogen-doped carbon quantum dots (NCDs) modified MXene (MXene/NCDs) composite coatings with “dual-action” effects were meticulously fabricated on the Ti6Al4V surface through grafting silane coupling agent and dopamine adhesion layers via chemical self-assembly techniques. The friction coefficient and wear rate of MXene/NCDs coated titanium alloy in SBF lubricant significantly decreased by 31.7 %and 91.6 %, might due to the double effect of MXene sheet slipping and NCDs rolling. Furthermore, the enhanced anticorrosion properties of MXene/NCDs coating were attributed to the ionic reaction between the surface of coating and SBF, effective shielding mechanism against the infiltration of active ions within the solution, indicated that the coating is expected to be applied in artificial joint system.
