Modification of the hot work tool steel surface by different thermochemical treatments
The surface of the hot work tool steel X37CrMoV5-1 (W300) grade 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 aluminising + nitrocarburising with or without post oxidation were performed. Nitrocarburised and nitrocarburised + post oxidised layers were characterized by testing their basic properties (compound layer thickness, nitrocarburising depth, micro hardness) as well as their corrosion resistance. First, the microstructures of aluminised + nitrocarburised samples (with or without post oxidation) were analysed by means of optical microscopy, and then the micro hardness distribution across the surface layer. Finally, the corrosion resistance of aluminised + nitrocarburised samples (with or without post oxidation) were examined. The Glow Discharge Optical Spectroscopy (GDOS) was employed to investigate the distribution of elements in the coating layer of tested samples.
