Implantation of Metal Ions into High Speed Steel for Improved Tribology

Abstract

AbstractHigh speed steel with a martensitic microstructure is widely used in tool industry, but often the usage is limited by severe abrasive and corrosive wear. Metal ion implantation is a promising method to improve the tribological behaviour of this steel, as was shown in several publications. In this paper we discuss the application V and Cr implanted high speed steel, both of these elements are alloying constituents of the steel matrix. Combined with implantation of carbon is also carried out.The tribological tests were performed with a pin-on-disc machine under dry sliding conditions. The obtained tribological results are discussed in relation to the microstructures of the nonimplanted and implanted samples.
