Comparison of corrosion, tribocorrosion and antibacterial properties of silver coatings on Ti15Mo by magnetron sputtering

The aim of this in vitro study was to evaluate the influence of + Ag coated conditions on the corrosion, tribocorrosion, antibacterial properties of Ti15Mo specimens. The mean wear volume loss of all test specimens after tribocorrosion test procedures were determined to use a noncontact 3D profilometer. The specimens hardness, roughness and microstructures were measured using the micro-hardness tester, surface profilometer, scanning electron microscopy (SEM) and Xray diffraction (XRD) analysis. The mean wear volume loss of 30 min + Ag coated Ti15Mo specimen was lower than the other specimens. In this study, correlations between the hardness, surface roughness and wear volume loss were found to be significant. The PVD coating process enhanced the antibacterial activity of Ti15Mo specimens owing mainly to the formation of the silver film on substrates
