Hot-forging dies, made of AISI-H13 hot-work tool steel, were plasma-nitrided in order to improve the surface properties of the material. A diffusion layer without the white layer was formed on the material by controlling the nitriding parameters: vacuum pressure, temperature, N2 / H2 ratio and DC bias potential. The nitriding time was varied from 2 to 16 hours. Micro-hardness measurements were performed on the surface and through the diffusion layer for each nitrided material. Optical… CONTINUE READING
