Development of silver film coating on dental ti15mo alloy to enhance two-body wear resistance, biocompatibility and cytotoxicity effect

The basic aim of this in vitro study was to investigate the effects of different silver deposition times on the two -body wear, antibacterial and cytotoxicity properties of silver ions on Ti15Mo alloy. The direct current (DC) magnetron sputtering technique was used to create silver films at different times (30, 45 and 60 minutes); the experimental setup was predetermined. The phase structures, cross-sectional morphology, surface roughness, two-body wear behavior, antibacterial and cytotoxicity properties of all specimens were researched in detail. The surfaces of all films showed a homogeneous distribution. It was observed that silver films enhanced the two-body wear resistance of Ti15Mo alloys. Furthermore, significant correlations were discovered between hardness, surface roughness and wear volume loss. Compared to Ti15Mo alloys, the antibacterial and cytotoxicity test results showed that silver films deposited 30 and 45 min had superior antibacterial and biocompatibility properties.
