In the current study, a high-velocity oxyfuel (HVOF) system is used to generate an enhanced temperature sliding wear-resistant iron-based (FeNiCrMo) composite coating on a boiler steel substrate. FeNiCrMo (70%) and WC-12Co (30%) were mechanically mixed prior to coating utilizing the ball-milling technique. The HVOF system later used feedstock to create the coating. The coating samples were put through the necessary metallurgical and mechanical characterization processes. With pin-on-disc equipment, additional substrate and coating samples were acquired for a wear test without the need of lubrication. By using 10-N and 20N loads at room temperature and 200°C and 300°C conditions, wear tests were conducted.
