Alloying contact zones by metallic nanopowders in sliding wear

Mechanical mixing and alloying in wear of steel-to-steel friction pair in the presence of metallic nanopowders have been investigated using XPS, SEM. Wear and friction coefficient dependencies have been obtained to demonstrate the effect of the mechanical alloying on both friction and wear. It has been shown that nanoadditives reduce friction and wear, modify surface roughness of worn surfaces and take part in forming mechanically mixed layers (MML).
