Tribological Behaviour of Ion-Implanted SiC Ceramics

Abstract

Polycrystalline SiC was implanted with Ar⁺ ions, in order to investigate the effect of ion-implantation on the tribological properties of the ceramics. By Ar⁺ ion implantation, the friction coefficient μ for a steel(SUJ2) pin sliding against SiC disk was found to he decreased remarkably. Results from Raman spectroscopy indicated that the observed reduction in μ is related to the amorphous surface layer produced by the implantation.
