Notes:
Two type of ceramic composite coatings of Fe-Cr-B alloy reinforced with cobalt-coatedtungsten carbide (WC-Co) particles or nickel-coated tungsten carbide (WC-Ni) particles weredeposited on a mild steel substrate by arc spraying, respectively. The microstructure of the coatingwas investigated by optical microscopy. X-ray diffraction analysis was used to study the phasecomposition in the coating. The microhardness of the coating was determined. The wear behavior ofthe coating was evaluated. The results showed that the WC-Co/FeCrB coating has the excellentabrasive wear resistance which is about 11 times higher than that of Q235 mild steel. The main wearmechanism of both coatings was silica scratching and micro-cutting of the matrix and the resultantpulling out of WC particles
