The enhancement of wear resistance for nitrogen-implanted tungsten carbide
Abstract
The enhancement of the wear resistance for tungsten carbide (WC-Co) is investigated by using an ion implantation technique. A ball-on-disc-type tribometer confirmed that the wear resistance was systematically increased with increasing dose and implantation energy of the nitrogen ions. In accordance with the increase in the wear resistance, the nano-indentation measurements showed that the hardness for the nitrogen-implanted WC-Co with an energy of 120 keV (dose: 1 × 1018 ions/cm2) was increased by about 2.8 times compared to that for as-received WC-Co.
