Fatigue-like failure of thermally oxidised titanium in reciprocating pin-on-plate wear tests

Characterization of thermally oxidized Ti6Al7Nb alloy for biological applications

“…Although there are several surface modification techniques proposed in the literature, all of which are reported to be effective for increasing wear resistance, thermal oxidation (TO) appears to be a simple and cost effective way for this purpose [10][11][12][13][14][15][16][17]. This technique is based on oxygen diffusion into the material at elevated temperatures and enables surface hardening due to the formation of a relatively thick TiO2 layer on the surface with an oxygen diffusion zone (ODZ) beneath it.…”

Ceramic conversion treatment of titanium-based materials

“…14.6). Fatigue-like failures of CC treated titanium and its alloys have also been observed in reciprocating pin-on-plate sliding wear (Dahm, 2009) and wheel-on-wheel rolling-sliding wear tests (Dong and Bell, 2000). Interfacial fatigue was observed, as evidenced by the bench marks, when the applied load is above a critical value (Dong and Bell, 2000).…”

“…Since then, many researchers are exploring the potential of CCT for different titanium materials, such as CP Ti Qi, 2000;Krishna et al, 2007;Dahm, 2009), Ti-6Al-4V (Borgioli et al, 2005;guleryuz and Cimenoglu, 2005;Yazdanian et al, 2007;Biswas and Majumdar, 2009), Timet 550 (Boettcher et al, 2002), SP700 (Komotori et al, 2001;Kim et al, 2008), Ti-10Ta-10Nb (Ahn et al, 2008), Ti-6Al-17Nb (Meydanoglu et al, 2008) to achieve a variety of surface properties. The CCT technology has also been applied to TiAl intermetallics (Xia, 2004) and TiNi shape memory alloys (Ju, 2007).…”

“…Interfacial fatigue was observed, as evidenced by the bench marks, when the applied load is above a critical value (Dong and Bell, 2000). It has been found that interfacial fatigue progressed from isolated blisters, through widespread blistering, to final rupture of the oxide layer (Dahm, 2009).…”

Oil Dispersed Polymers Characteristics under External Voltage, Tribological and Corrosion Variables

“…The variation of sliding velocity is complex because the mechanism of wear include deformation and interfacial components, transfer also play an important role. For these reasons, no unique trend between wear rate and sliding velocity is to be expected and experiments show, that wear rate/sliding velocity relationships exhibiting maxima, minima or little variation can all be obtained, depending on the materials involved and the precise conditions of sliding imposed [22][23][24][25][26][27][28][29][30].…”
