ABSTRACT
The application of titanium as medical implants is limited to a certain extent due to its insufficient corrosion resistance, biological activity, and antibacterial ability. In this work, a gradient nanograined (GNG) layer was fabricated on the titanium surface by surface ultrasonic rolling treatment (SURT). The subsequent copperizing kinetics was greatly enhanced so that a thick copperized layer could be obtained on the surface of GNG Ti at a relatively low diffusion temperature (450 °C). Meanwhile, the GNG structure accelerated the release rate of Cu2+, which endows GNG Cu/Ti with strong antibacterial activity. Moreover, the corrosion resistance and cytocompatibility of GNG Cu/Ti were also evidently improved compared with coarse-grained Ti, indicating a good biomedical application prospect.
