Structure and properties of the diffusion layer of die steels after chrome−vanadium−nitriding

1. The diffusion layer on die steels after chrome-vanadium-nitriding contains type MN, M2(N, C), and M7C3 phases and nitrogen ferrite. 2. Nitriding of chromized and chrome-vanadized die steels leads to a significant increase in their scale and wear resistances.
