The application of the ion‐beam technique to the nitriding of steels is described. Preliminary results indicate that the technique can be successfully applied for this purpose. Some of the structural changes obtained by this technique are similar to those obtained by ion nitriding. The main difference is the absence of the compound layer and the iron nitrides diffraction lines. The dependence of the resultant microhardness on beam voltage for super nitralloy was found to be different from that of 304 stainless steel.
