Wear properties of nanocrystalline aluminum alloys and their composites

Friction and wear behavior of surface nanocrystallized aluminium alloy under dry sliding condition

“…A few research works has been published on the tribocharacteristics of nanocrystalline surfaces [4][5][6][7][8]. The friction and wear resistance of nanocrystalline surface layer of low carbon steel and pure copper produced by surface mechanical attrition technique process shows a decrease in friction coefficient and improved wear resistance [4,5].…”

Effect of sintering on microstructure and mechanical properties of nano-TiO2 dispersed Al65Cu20Ti15 amorphous/nanocrystalline matrix composite

“…Both these non-equilibrium processing routes are known to significantly decrease the grain size, enhance solid solubility limit, increase volume percent of the precipitate (intermetallic) phase and even transform the crystalline aggregate into amorphous or glassy product. Among the most widely studied systems, melt spun Al-Ln-Tm (Ln = lanthanides like Y, Ce; Tm = transition metals like Ni, V, Cr) are known to develop nanocrystalline/glassy product with high strength [11][12][13][14]. It has been suggested that strength of the amorphous materials can be further enhanced, and limited ductility can be introduced through the dispersion of nanometric phases [15][16][17].…”

Fretting wear behavior of nanocrystalline surface layer of pure copper under oil lubrication

“…During the last decade, tribological properties of nanostructured materials have been paid more attention and many experimental results have shown a significant enhancement in friction and wear properties of nanostructured materials, e.g. [1][2][3][4][5]. However, it should be mentioned that most investigations on wear properties of nanostructured materials have been focused on sliding wear mode.…”
