Earlier works have demonstrated that Fe2B-based arc-sprayed coatings and weld overlays present outstanding dry erosion resistance when compared to other carbide-based coatings and overlays. The present work was undertaken to examine their wear resistance, particularly their slurry erosion resistance. Cored wires containing chromium (2-20 wt%) and carbon (0.2-1.2 wt%) additives were deposited by arc spraying and gas metal arc welding (GMAW). The abrasion, particle erosion and slurry erosion resistances of these (Fe-B-Cr-C) coatings and overlays were evaluated in laboratory. The results demonstrate that both differences in cored wire composition and variations in the deposition process must be considered in order to obtain the best wear properties.
