Ion nitriding is one of the most effective chemical heat-treatment technologies that significantly improve the performance characteristics of steels. In modern manufacturing, where the requirements for material strength and wear resistance are continuously increasing, optimizing ion nitriding conditions is particularly important. The effects of treating 20H13 and 09G2S steels at 450–550 °C for 4–12 h at a pressure of 300 Pa in a gas mixture of 90% N2 and 10% Ar, were investigated both with and without the hollow cathode effect (HCE). Surface microhardness, nitrided-layer depth, and microstructure were evaluated. The highest values were obtained at 450 °C after 12 h with HCE. The surface microhardness of 20H13 steel reached 1305 HV50 with a layer depth of 180 μm, while that of 09G2S steel reached 960 HV50 with a layer depth of 120 μm. The nitrided layers exhibited a gradual transition to the substrate and a well-defined diffusion zone. The use of HCE increased the surface microhardness by approximately 36% and 24% and the layer depth by 80% and 71% for 20H13 and 09G2S steels, respectively.References
