Abstract
This study explored enhancing WC-12Co coatings' performance and preventing decarburization by adding Cr, Cr3C2, and VC. Coatings were prepared using HVOF technology, and their microstructure, mechanical properties, wear behavior, and corrosion resistance were analyzed. Results indicated that VC and Cr3C2 add-ins effectively prevented decarburization, with T2 coatings (WC-12Co-2VC-2Cr3C2) showing lower porosity, higher hardness, and improved wear resistance. However, T1 coatings (WC-12Co-2VC-2Cr) demonstrated superior corrosion resistance due to Cr addition. The findings provide insights into the additives' effects on WC-12Co coatings and underscore the potential of VC and Cr3C2 as decarburization inhibitors.
