Effect of Tungsten Carbide Addition on the Wear Resistance of

Abstract. Ni-graphite coatings are widely used in industrial fields to improve the self-lubrication property of metallic surfaces. In this study, the effect of tungsten carbide (WC) addition on the microstructure, hardness and wear resistance of flame-sprayed Ni-graphite coatings was investigated. Microstructure examination of coatings shows that WC particles adhered well to Ni matrix but tended to come into contact with each other or graphite particles with the increasing addition amount.

Wear resistance of cast graphitic aluminium alloys

The high wear resistance is attributed to the presence of graphite particles in the matrix which act as a solid lubricant. Additions of nickel alone to Al-Si alloys decrease the wear resistance. Graphitic aluminium-silicon-nickel alloys containing above 2% graphite can be mated unlubricated against the rotating steel disk after a one minute

Wear Resistance Limited by Step Edge Failure: The Rise and

Similar behavior with substantially reduced wear resistance at the edge was also observed for monatomic graphene layer on graphite surface. Using molecular dynamics simulations, we attributed this markedly weak wear resistance at the step edge to two primary mechanisms, i.e., atom-by-atom adhesive wear and peel induced rupture.
