Thermochemical treatment of steels in the plasma of a hydrostatic glow-spark discharge
- 201 Downloads
This article presents results from studies of the thermochemical treatment of steel parts based on their nitriding in the plasma of a hydrostatic glow-spark discharge (GSD). The article examines the nitriding of carbon and alloy steels in a GSD plasma (hydroplasma nitriding), as well as combination methods of treating carbon steels. One of the combination methods discussed is diffusion saturation of the steel by a metal, nitrogen, and carbon.
