“…After wearing under the high applied load of 20 N the un-processed Ti sample has experienced severe surface damage (Figure 9(c, d)). As a rule of thumb, the tribolayer stability is significantly influenced by its substrate mechanical properties namely hardness and toughness [43]. Therefore, the formation of large metallic patches free of protective tribolayer on the worn surface can be regarded as an indication of extensive tribolayer delamination that is seemingly occurred as a result of the increased temperature (substrate softening) and lack of sufficient support from the tribolayer.…”

Friction surface stirring (FSS) was employed to enhance the tribological properties of commercially pure Ti (CP-Ti). Applying FSS under the optimised process parameters (i.e. rotation and traverse speeds of 100 rpm and 8 mm/min, respectively) was found to increase the surface hardness of as-received CP-Ti from about 200–630 HV. The sliding wear resistance was therefore increased by 76, 76, and 85% under applied loads of 5, 10, and 20 N, respectively. The average friction coefficient (AFC) of CP-Ti also reduced considerably by the FSS. For instance, the AFC was reduced from 0.67 ± 0.07 and 1.04 ± 0.14 to about 0.33 ± 0.03 and 0.45 ± 0.04 at the applied loads of 5 and 20 N, respectively. The wear and friction mechanisms were also discussed.
