“…As the fretting process continued, the surface morphologies of the fretting contact zones became coarser, leading to stress concentration. Stress concentration could promote the initiation of the micro-cracks [6,20]. Some micro-cracks on the subsurface gradually extended to the free surface, resulting in the patch delamination in the fretting contact zones of BM and Cr-Ti samples.…”

“…To solve the problem of FF damage, the anti-wear and anti-fatigue properties of Ti alloys should be simultaneously improved. Surface hardening treatments can improve the wear resistance remarkably [6][7][8] but often reduce the fatigue resistance, owing to the low toughness of the hardened surface [9][10][11][12], making it difficult to solve the anti-wear and anti-fatigue issues through a single surface treatment.…”

This work reported a comparison between the wear and fretting fatigue (FF) behaviors of a Cr-alloyed layer and a Cr-Ti solid-solution layer. The hardness and toughness of both layers were evaluated to support this comparison. The results showed that the Cr-alloyed layer had high surface hardness but poor toughness, while the Cr-Ti solid-solution layer had excellent toughness but low hardness. The FF properties of the modified Ti6Al4V alloy depended on the trade-off between two factors: wear resistance and fatigue resistance. Although the Cr-alloyed layer could effectively resist the wear in fretting areas, its poor toughness caused the fatigue resistance to drop sharply and hence led to a premature failure in FF test. Due to the relatively good fatigue resistance, the Cr-Ti solid-solution layer had slightly higher FF life than that of the Cr-alloyed layer; however, its low hardness resulted in severe wear in correspondence with the fretting area and thus a failure to improve the FF properties of Ti6Al4V alloy. When combined with shot peening post-treatment, the FF life of both layers increased by about three times compared to that of the Ti6Al4V alloy. A further study showed that the poor toughness or low hardness still exerted negative influence on combination-treated samples.

“…Previous studies have shown that the embedding of WC particles in the Ni matrix changes the shape of Ni crystallites from pyramidal to quasi-spherical and reduces their average grain size [2,20,21]. In this work, nickel matrix with the finest grain size achieved by using 0.10 gL -1 SDS in the plating bath.…”

Although the content of co-deposited Mn in the matrix increases as duty cycle is increased, it does not affect the hardness.…”

Composition modulated nanocomposite of NiFe-Mn-Al 2 O 3 coatings were fabricated on mild steel using single bath technique through alternative variation of duty cycle at constant frequency (VD) and repeated alteration of frequency at constant duty cycle (VF). The number of layers was 32 and thickness of each layer was 2.5 lm. The results of microstructure examination by SEM and EDS for VD coatings exhibited that Fe/Al 2 O 3 -rich layers adjacent to Mn rich ones were deposited in a frequent manner. In the case of VF coatings, alternative variation of frequency did not affect the chemical composition of matrix and only changed the content of embedded nanoparticles. The microhardness of Ni-Fe-Mn-Al 2 O 3 multilayers compared to monolithic and multilayer Ni-Fe-Al 2 O 3 of the same thickness was significantly increased because of Mn incorporation into the matrix. The corrosion resistance was found to be better for VD coating in comparison to the VF ones.
