Description	The P/M made VANADIS 6 cold work steel was plasma nitrided. Important surface characteristics like the microstructure, the hardness and microhardness, the nitrogen concentration depth profiles, the phase occurrence and wear behaviour were investigated. The core material consists of the MC- and M7C3- carbides, uniformly distributed in the matrix. Plasma nitriding led to the increase of both the surface hardness and the microhardness, due to the nitrogen saturation of thin near surface region. This promotes the formation of Fe4N- and Fe3N-nitrides and, at the highest processing temperature and longer time, also the CrN-phase. The occurrence of nitrogen enriched region at the surface increases the wear resistance. On the other hand, the fracture toughness drops down.
