Effect of sliding speed on friction and wear behaviour of nanocrystalline nickel tested in an argon atmosphere

Tribological Behaviour of Pure Ti with a Nanocrystalline Surface Layer Under Different Loads

“…The wear mechanism changed from abrasive and adhesive wear under 1-2 N to abrasive wear under 5 N for CG Ti. The different wear mechanism between nanocrystalline/ UFG alloys and CG counterpart has also been reported by other researchers [15,16,[18][19][20][21]. For example, UFG CuAl-Fe alloy showed only abrasive wear characteristics while the wear track of CG counterpart showed large extent of adhesion wear (delamination) and severe plastic deformation in sliding direction [21].…”

Sliding wear behavior of nanocrystalline nickel coatings: Influence of grain size

“…However, other investigators have also indicated the importance of surface oxidation [9,11] and its role in wear and friction of nanocrystalline Ni. If the influence of grain size on the wear rate is entirely through its effect on hardness (i.e., HallPetch relationship, Fig.…”

“…In addition, the earlier work of Shafiei et al [11] has evaluated the wear behavior of nc-Ni coating, having a single grain size (15 nm). In the present study, PED Ni coatings with three grain sizes in the nano regime (21, 42 and 195 nm) have been subjected to wear tests in order to study the influence of grain size on COF and sliding wear rate.…”

Tribological behavior of Fe70Ni30 alloy with nanoscale twins under liquid paraffin lubrication

“…[4][5][6][7][8][9][10][11] Because the large volume fraction of grain boundaries could block the dislocation movement, 3 the strength and hardness of the nanostructured metals improves significantly, which is beneficial to the enhancement of their wear resistance. Wang et al 4 reported that due to the hardness improvement, the wear resistance of nano-eutectic Fe 1.87 C 0.13 alloy is about 2-6 times higher than that of the annealed coarse-grained counterpart.…”
