| Abstract: | Decarburization poses a significant challenge in HVOF-sprayed WC-12Co coatings, leading to a decline in overall performance. To address this issue, this experimental study explores the impact of incorporating cerium oxide (CeO2) on tungsten carbide coatings' dry erosive and abrasive wear behavior. The deposition of coatings onto low-carbon AISI 1020 grade steel was accomplished using a high-velocity oxy-fuel (HVOF) coating technique. Various aspects of the coatings, including microstructure, phase composition, porosity, adhesive bond strength, and microhardness, were thoroughly examined. Analysis of the coatings' cross-sectional morphology revealed that the grains of CeO2-modified WC-12Co coatings exhibited a finer structure than conventional WC-12Co coatings. The addition of rare earth oxides reduced porosity while having minimal impact on bond strength; specifically, the modified coating with a 2 wt.% cerium oxide content displayed a microhardness of 1320 ± 70 HV0.3 and an adhesive bond strength of 73.60 ± 5 MPa. Notably, this modified coating demonstrated enhanced erosive and abrasive wear resistance and the optimized addition of 2 wt.% shows 20 and 130% lower erosive and abrasive wear than the conventional WC-12Co coating, respectively.
