Technological Possibilities of Different Nitriding Techniques for Saturation of Heat-Resistant Steels of Martensitic Class

  • Published:
Metal Science and Heat Treatment Aims and scope

Complexly alloyed heat-resistant martensitic steels VKS-7 and VKS-10 are studied after nitriding. Comparative analysis of the curves describing the variation of microhardness of the diffusion layers, of the rates of their formation, and of the microstructure over the thickness of the specimens nitrided by different methods (vacuum, gas, and ion (in glow discharge) ones) is performed. It is shown that the diffusion layers in heat-resistant steels do not have an embrittling nitride net after vacuum nitriding and acquire such a net after ion and gas nitriding. The saturation over the contour of the treated parts with narrow channels and blind holes is shown to be substantially more uniform due to vacuum nitriding with cyclic pressure variation as compared to the other nitriding methods. The maximum saturation rate is provided by the ion processes. The distribution of microhardness is the more even after vacuum nitriding.
