摘要

The tribological properties, electrochemical corrosion resistance, and biocompatibility performance of Ti6Al4V alloy were improved through a duplex surface treatment process consisting of high-temperature gas nitriding followed by amorphous carbon nitride (CN) coating deposition. The tribological properties of the specimens were evaluated using a reciprocating sliding wear tester, while the electrochemical properties were examined by potentiodynamic polarization tests. Finally, the biocompatibility of the samples was investigated by means of cytotoxicity tests performed using mouse leukemic monocyte macrophage cells (Raw 264.7). The duplex treatment significantly improved the tribological performance of the Ti6Al4V sample. In particular, compared to an untreated Ti6Al4V sample, the duplex surface treatment (CN-NTs) reduced the wear depth by around 55 times when sliding against a 316L counterbody and 16 times when sliding against a Ti6Al4V counterbody. Of the various specimens, the CN-T sample showed the best corrosion resistance, while the CN-NT sample showed the best biocompatibility performance.
