“…The large fluctuation of the friction coefficient at 10 N load was possibly due to formation of cyclic, localized fracture of a transfer layer of softer material which is of titanium alloy in this case thus indicating that the possible wear mechanism here is three body abrasion. Similar results have been reported by some earlier investigators for ceramic, polymer and metal counter face materials [12].…”

Friction and wear are the most commonly encountered industrial problems leading to the replacement of components and assemblies in engineering. There have been great advances in the development of aerospace technology because of the use of titanium alloys. Titanium alloys have wide range of applications for which they have received considerable interest recently because they show an astonishing range of mechanical properties. The present investigation covers the study of dry sliding friction and wear of the Ti6Al4V alloy, which alone covers about 50% of the total world production of titanium alloys. The main objective of this study is to investigate the dry sliding friction and wear behaviour of titanium alloy (Ti-6Al-4V) sliding against EN31 steel. The results show that the wear rate of the Ti6Al4V alloy decreases with increasing sliding velocity and decreasing normal load with few exceptions thus showing typical transition characteristics. The average coefficient of friction decreases as the normal load increases with few exceptions. Also the average coefficient of friction increases as the sliding distance increases for all loads and sliding velocities. The average length of biggest, medium and smallest wear debris was found to be 1.026 µm, 0.711 µm and 0.401 µm respectively.

“…Large frictional fluctuations occurred when metal and ceramic balls slide against Ti-alloy disks. Higher friction coefficient with larger fluctuation and high wear rate were observed at the lower sliding speed [12]. The dry sliding wear resistance of the oxidised titanium strongly depends on the material of the counterbody.…”

“…Specific wear rates of as-sintered Ti2Cu and Ti 10Cu were 1.23 © 10 ¹13 and 1.16 © 10 ¹13 m 3 /N·m, respectively. The obtained specific wear rates were similar to those reported by J. Qu et al 23) In their study, Ti6Al4V sliding against 440C stainless steel yields specific wear rate between 1.5 © 10 ¹13 and 1.7 © 10 ¹13 m 3 /N·m. This means that wear performance of sintered TiCu alloys and Ti6Al4V alloy against stainless steel were comparable.…”

Titanium2 mass%Cu and Ti10 mass%Cu alloys were fabricated by powder metallurgy. The alloys were precipitation hardened to observe effect of heat treatment to their wear property. It was found that hardness of the two alloys increased after solution treatment to 320 and 526 HV, and after aging to 441 and 612 HV. However, wear resistance, as characterized by friction coefficient and mass loss in a pin-on-disc wear test deteriorated. In term of wear resistance, a lamellar morphology of eutectoid ¡Ti/Ti 2 Cu was favorable to the homogenized morphology of heat treated alloys. Lowest specific wear rate was found in as-sintered Ti10 mass%Cu, having a value of 1.16 © 10 ¹13 m 3 /N·m.

“…Current developments in Ti processing predict the accessibility of lower-cost Ti and have revived interests in exploring the tribo-behaviour of Ti alloys as bearing materials [15][16][17][18]. Titanium and its alloys exhibit low tribological properties but their wear resistance can be improved by surface treatments promoting growth of the surface hardness, leading to changes of the wear mechanism and a lowering of the wear rate [19].…”

This paper deals with the study of the enhancement of the tribological properties of AA2024 through the deposition of a titanium coating. In particular two different coatings were studied: (1) untreated titanium coating; and (2) post-deposition laser-treated titanium coating. Titanium grade 2 powders were deposited onto an aluminium alloy AA2024-T3 sheet through the cold gas dynamic spray process. The selective laser post treatment was carried out by using a 220 W diode laser to further enhance the wear properties of the coating. Tribo-tests were executed to analyse the tribological behaviour of materials in contact with an alternative moving counterpart under a controlled normal load. Four different samples were tested to assess the effectiveness of the treatments: untreated aluminium sheets, titanium grade 2 sheets, as-sprayed titanium powders and the laser-treated coating layer. The results obtained proved the effectiveness of the coating in improving the tribological behaviour of the AA2024. In particular the laser-treated coating showed the best results in terms of both the friction coefficient and mass lost. The laser treatment promotes a change of the wear mechanism, switching from a severe adhesive wear, resulting in galling, to an abrasive wear mechanism.
