Research Progress of Plasma Nitriding in Low-Temperature for Austenitic Stainless Steel

Abstract:

In recent years, as a kind of heat treatment methods to improve the performance of the material surface, plasma nitriding gets more and more widely used. Among some new ways of plasma nitriding, treating of surface nano-crystallization before plasma nitriding has been more and more attractive. This technology is also applied to stainless steel on plasma nitriding in low-temperature, for it can not only improve the hardness and wear resistance of material surface, but also enhance corrosion resistance. In the article, several assistive technologies about plasma nitriding in low-temperature are described, including surface nano-crystallization, laser surface strengthening and pre-oxidation. Meanwhile, proposes that the further research will focus on the surface nano-crystallization before plasma nitriding in low temperature in the future.
