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 wear resistance (about 48 times) than that of the Ti-6Al-4V alloy tested under a normal load of 45 N. Severe delamination is found to be responsible for the low wear resistance of Ti-6Al-4V. In the case of Ti-24Al-11Nb, two wear mechanisms have been suggested: delamination with a lower degree of severity and oxidative wear. It is thought that the ability of Ti-24Al-11Nb to form a protective oxide layer during wear results in a much lower wear rate in this alloy. (C) 2002 Elsevier Science Ltd. All rights reserved.
