In general, neon implantation is not very effective in reducing wear rates. However, neon implantation into laser-melted steel turns out to reduce the wear rate substantially as a result of a conversion of residual tensile stresses into compressive ones. Nitrogen implantation, on the other hand, at a high dose of 3×1017 ions/cm2 at 90 °C exhibits a deleterious effect on the wear performance. A brittle layer of ε-Fe2(C,N)1-x nitrides is formed. At a lower dose of 1×1017/cm2 or implantation of nitrogen at 150 °C, the wear rate is also reduced.
