Abstract
CrMoSiCN/Ag coatings are prepared on Ti6Al4V alloy via adjusting the Ag target current. The static antibacterial rates of CrMoSiCN/Ag coating H3 are 97.7 % and 94.5 % for E. coli and S. aureus. However, due to the formation of Ag2Mo2O7 tribolayer, the antibacterial rates of coating H3 with wear track further raise to 98.7 % and 96.6 % for E. coli and S. aureus, and the tribo-induced antibacterial enhancement effect is obvious for CrMoSiCN/Ag coating. Besides, the electrochemical noise and polarization results indicate that the corrosion mechanism of coating transfers from uniform corrosion to pitting corrosion with an increase in the Ag content. The electrochemical simulation result demonstrates that the galvanic corrosion at the interface of coating/substrate will accelerate the loss of coating material when the corrosion current icorr value of coating is close to that of substrate.
