The surface of the hot work tool steel X37CrMoV5-1 (W300) was subjected to different thermochemical treatments in order to improve its mechanical properties, corrosion and wear resistance. Nitrocarburising with or without post-oxidation based on the TENIFER procedure and low temperature powder aluminisingznitrocarburising with or without post-oxidation were performed. Nitrocarburised and nitrocarburisedzpost-oxidised layers were characterised by testing their basic properties (compound layer thickness, nitrocarburising depth and microhard-ness) as well as their corrosion resistance. First, the microstructures of aluminisedz+nitrocarburised samples (with or without post-oxidation) were analysed by means of optical microscopy, and then the microhardness distribution across the surface layer. Finally, the corrosion resistance of aluminised+znitrocarburised samples (with or without post-oxidation) were examined. Glow discharge optical spectroscopy was employed to investigate the distribution of elements in the coating layer of tested samples. © 2012 IHTSE Partnership Published by Maney on behalf of the Partnership.
