“…However, for many engineering applications (including in automotive applications like pistons and cylinder heads) wear accounts for more than 50% of materials losses in service [12][13][14] and thus the exploration of the tribological properties and wear resistance of the novel nanocrystalline Al alloys is of critical importance.…”

Nanocrystalline Al-Ni-Gd-Co alloys with exceptionally high hardness have been recently developed from amorphous precursors. In the present work, the reciprocating sliding wear in the gross slip regime of these novel nanocrystalline Al-based alloys has been investigated under small amplitude oscillatory sliding motion using a martensitic chrome steel as the counter material. When compared to pure Al or Al-12Si alloy, these nanocrystalline alloys exhibit excellent wear resistance and a lower coefficient of friction when sliding against steel. The 2 enhanced wear resistance of the novel nanocrystaline Al alloys is related to their ultra-high hardness and the hybrid nanostructure that mainly consists of nanometric intermetallic phases embedded in a nanocrystalline fcc-Al matrix. Three body abrasive conditions were created at the initial stages of the wear tests due to the formation of micro-and nano-particulate debris from the worn surface of the Al alloys; the debris was compacted under the subsequent sliding cycles forming layers that are protective to the extensive wear of the Al alloys.

“…Recent extensive research in the field of surface engineering is driven by the progressive growth of the need for high wear-resistant surfaces that have enhanced physical properties using diverse techniques. Yuan et al [2] improved the wear resistance of aluminum by reinforcing it with in situ AlB2 particles. Rao and Das [3] improved the wear resistance of AA2024 alloy by reinforcing it with SiC particles.…”

Laser surface alloying is one of the recent technologies used in the manufacturing sector for improving the surface properties of metals. Aluminum alloys are key materials in the manufacturing sector. This favors their high demand in many industries. In this study investigation, the surface alloying of pure aluminum was conducted using a CO2 laser. Four types of alloying powders were used with a 2:1:1 combination of copper, magnesium, and manganese. The hardness of the alloyed zones of Al-CuMgMn increased by 2 to 7 times at a 1.7 kW processing laser power. To assess the rate of wear for the alloyed samples, a modified Lancaster wear coefficient was considered. When the pin-on-disc wear test at 10 N and 20 N loads was analyzed with different sliding speeds, a reduction in wear by 30–50% appeared due to surface alloying. The result shows good insight into the wear behavior. In the same way, microstructure and surface morphology studies displayed a good metallurgical bonding without defects. In a statistical sense, the friction and wear behavior matched with an asperity-based model. The experimental results revealed that laser surface alloy has more wear resistance.

The analysis of structure, defect substructure, elemental and phase compounds and friction properties of Al-11wt%Si alloy surface layer of subjected to complex treatment was carried out by methods of scanning and transmission electron microscopy. Complex treatment includes the electroexplosion influence by Al-Y 2 O 3 compound and subsequent electron beam irradiation. The surface layer ≈ 80 μm thick is formed by high-velocity crystallization cells of 0.8-1.3 μm in dimension. Interlayers 50-75 nm thick located along the cells of high-velocity crystallization are enriched by atoms of silicon and yttrium. Complex surface treatment leads to the increase by 18 times in wear resistance and decrease by 1.6 times in the friction factor of the modified layer.
