Response Of Ti-6al-4v And Ti-24al-11nb Alloys To Dry Sliding Wear Against Hardened Steel

A.S. Md Abdul Haseeb

Titanium alloys have been of great interest in recent years because of their very attractive combination of high strength, low density and corrosion resistance. Application of these alloys in areas where wear resistance is also of importance calls for thorough investigations of their tribological properties. In this work, Ti-6Al-4V and Ti-24Al-11Nb alloys were subjected to dry sliding wear against hardened-steel counter bodies and their tribological response was investigated. A pin-on-disc type apparatus was used with a normal load of 15-45N and sliding speed of 1.88 ms -1. In the steady state, it was demonstrated that Ti-24Al-11Nb had a substantially higher …
