“…A large amount of plastic deformation occurred in the contact zone with the substrate material being pushed out of the scar and collecting at the edges (Figure 10 (d)). This type of wear behaviour can be attributed to severe plastic deformation of the untreated substrate coupled with severe adhesive wear due to the high reactivity of titanium when the protective and inert natural surface oxide has been removed by mechanical action [29], [32]. Scratches, abrasive grooves and some cracks normal to the sliding direction can also be observed within the scar (Figure 10 (d) and (e)).…”

“…During the test cycle adhesive bonds are formed between the titanium surface and the transfer Ti layer on the WC-Co ball as the reciprocal movement proceeds. As these bonds break, they generate wear particles [32]. These particles strain harden and oxidise, which increases their hardness and in turn results in ploughingforming the scratches observed in the wear scar (Figure 10 The shallower wear track of Ti834 (compared to Ti64) occurs as a result of the former's higher hardness and different alloying elements, specifically, its larger content of alpha stabilisers which alter the wear mechanisms occurring.…”

Despite the popularity of a number of techniques of thermochemical diffusion for titanium, in many cases the surface engineering processes used may not be economically viable options for industry. This work focuses on the application of Powder Immersion Reaction Assisted Coating (PIRAC), a relatively inexpensive nitriding treatment that is capable of providing a remarkable improvement in the surface characteristics of titanium alloys. The aim of this work was to determine whether PIRAC could be successfully applied to Ti-6Al-4V and the high-performance near-titanium alloy Timetal 834. In order to study the response of these materials to PIRAC nitriding, techniques such as X-ray diffraction, micro-indentation hardness, surface profilometry, optical and electron microscopy, nano-scratch adhesion testing and ball-on-plate reciprocatingsliding wear testing were employed. These techniques highlighted the markedly different response between the two alloys to the PIRAC treatment; namely, that Ti-6Al-4V forms a thick compound layer, while at the same processing temperature and time Timetal834 does not form any appreciable Ti 2 N phase instead forming a nitrogen-diffusion case with a thin TiN compound layer at the surface. This inherent difference in nitridability influences the metallurgical response of each alloy. Despite this, the surfaces of both alloys were still hardened considerably and their tribological performance in dry sliding conditions improved compared to the untreated alloys.

Abstract. Sliding contact will experience wear in majority of mechanical components during their service life where it reduces the performance of the components. The capability to predict the evolution of reciprocating wear scars, such as the scar's width and depth, would be a valuable tool when designing mechanical components. Wear scar mechanism behaviour is characterised during stabilized cycle reciprocating sliding wear test of Ti-6Al-4V investigated using pin-on-flat arrangement under variable duration of sliding. The test samples were analyzed using profilometer test, optical microscopy test, Scanning Electron Microscopy (SEM) test, Energy Depressive X-ray (EDX) test and Vickers Hardness (HV) test. Stabilised high number of cycles shows low wear rate and initiation period of low cycles produced higher wear rate.

“…Among all biomaterials, the Ti6Al4V alloy is one of the most used material because, in addition to its excellent biocompatibility, it exhibits low elastic modulus (comparable with that of human bone), good corrosion resistance, high specific strength, and fatigue resistance [2][3][4][5]. In general, the orthopedic bearing is manufactured from highly polished metal alloys with extreme precision that articulate against a metal material (CoCrMo or stainless steel), ceramic material or against a polymeric material, mainly ultra high molecular weight polyethylene (UHMWPE), in case of knee joints.…”
