Abstract
Internal nitriding is a process of surface saturation with nitrogen, in which there forms a diffusion layer, consisting of nitride particles that are uniformly distributed in a solid solution but without a surface zone of continuous nitrides, as in conventional nitriding. This is achieved by selection of the alloy chemical composition and the nitriding process regimes. The presence of this diffusion layer opens up broad possibilities for the hardening of various alloys, since a high level of brittleness of the layer is avoided. This is an advantage over conventional nitriding.
