Effect of nitrogen-ion implantation on the unlubricated sliding wear of steel

Abstract

The effect of 30-keV nitrogen-ion implantation on the unlubricated sliding wear of type-38 NCD4 steel has been investigated. The effect of implants is seen to reduce the amount of wear for nitrogen doses above 1017 ions/cm2. The reduction in the wear persists also after removal of a material thickness greater than the penetration depth of the implanted nitrogen ions.
