Tribological behaviour of nitrogen-implanted materials

Tribological studies of ZrO2‐implanted on stainless steel substrate

“…Pictures of wear track for implanted and unimplanted 316L stainless steel samples are shown in Figure 4(a), (b). These results are consistent with earlier work (Dogan et al, 2002a, b;Fayewelle, 1986;Kulkarni et al, 1992;Onate et al, 1994;Wang et al, 2000;Zhang et al, 1994).…”

Tribological behavior of biomaterial for total hip prosthesis

“…Fretting and sliding wear conditions lead to damage and then fracture of the passive oxide film [5][6][7][8] which could be disrupted at very low shear stresses [9]. Unfortunately, Ti is an extremely reactive metal and has a reputation for poor tribological properties [10,11] and inferior performance when compared with other implantable. In general, the friction, wear and corrosion failures are the main reasons of degradation [12] and great difference of tribological characteristics between bone and implant must be limited to increase the service life of the surgical implants and to avoid bone degradation and adsorption [4].…”

Thermo-Electric Detection of Early Fatigue Damage in Metals

“…The Rockwell C hardness of Ti-6Al-4V is normally 30-36 HRC in the annealed condition and may increase to 39 HRC on age hardening and it is about 36 HRC in the solution-treated and over-aged condition [14]. Titanium is an extremely reactive metal and has a reputation for poor tribological properties [15][16][17][18]. Titanium does not gall against most metal counterfaces, but it does adhesively transfer and wears at a high rate.…”
