Consolidation of tool steel powders and simultaneous joining to a stainless 316L steel areperformed by hot isostatic pressing (HIP). Two tool steel grades are considered: a high vanadiumalloyed carbon tool steel, and a high vanadium and chromium alloyed nitrogen tool steel.The boundary layer arising during diffusion bonding is in focus and, in particular, the diffusionof carbon and nitrogen over the joint.Measurements of the elemental concentration profiles andcorrosion tests by the double loop–electrochemical potentiokinetic reactivation (DL-EPR)method are performed. Comparative calculations with the DICTRA software are performedand are found to be in agreement with the experimental results. It is found that the carbon toolsteel grade has a more critical influence on the corrosion resistance of the stainless 316L steel incomparison to the nitrogen tool steel grade.
