  In this study, satellite 6 and NiCrBSi coatings deposited on hot work tool steel DIN-2344/1 by thermal spraying and cladding were investigated. Stellite 6 and NiCrBSi powders were deposited on the substrate by HVOF and Stellate 6 wire were cladded by GTAW. Scanning electron microscopy with energy dispersive spectroscopy and optical microscopy, pins on disk wear machine, macro and micro hardness meter were used to analyze the coatings. Results showed that the hardness and wear resistance of thermal spray coating were higher than cladding coating. At high temperature, the results of wear test show, that the NiCrBSi coating has the better wear resistance rather than satellite 6 coating. This behavior of NiCrBSi coating attributed to silicate and boride particles in this coating. On the other hand, the thermal spray satellite 6 coating show the very low friction coefficient due to chromium oxide formed on the surface of coatings. Manuscript profile
