MECHANICAL AND TRIBOLOGICAL PROPERTIES OF OXIDE LAYERS OBTAINED ON Ti-6Al-7Nb ALLOY
Journal Title: Tribologia - Year 2016, Vol 267, Issue 3
Abstract
The research presented in the paper was focused on determining the effects of thermal oxidation parameters on the mechanical and tribological properties of oxide layers formed on Ti-6Al-7Nb titanium alloy for biomedical applications. Titanium alloy was oxidized at 600 and 700°C for 72h. The study found that, at lower temperatures, the oxidized alloy surface was covered by a nonuniform oxide layer. A 100°C increase in the treatment temperature yielded a uniform layer covering the whole surface of the alloy. Hardness measurements showed that thermal oxidation resulted in the formation of oxide layers characterized by a 3-fold higher hardness compared to untreated alloy. Tribological tests showed that thermal oxidation effectively improves the resistance of Ti-6Al-7Nb alloy to sliding wear. Tribological tests demonstrated that an increased oxidation temperature was associated with improved resistance to sliding wear.<br/><br/>
