Complex Deformation–Ion-Plasma Treatment of Steel 08Kh18N10T-Sh

Abstract

The structure and properties of the surface and of the core of steel 08Kh18N10T-Sh subjected to radial forging and subsequent saturation by the method of ion-plasma nitriding are studied. It is shown that the complex deformation–ion-plasma treatment accelerates the nitriding process and provides a high level of strength of the surface and of the core of steel 08Kh18N10T-Sh. The lower the saturation temperature, the shorter the hold time and the higher the degree of the deformation of the steel, the more deformed α-phase capable to accelerate the saturation process is preserved in the structure.
