The utilisation of non-traditional composite coating materials, enhanced lubrication, and surface geometry optimisation have all contributed to the tribological performance. Piston rings are among the most crucial engine parts since friction causes between 40 and 45 percent of all energy loss. Fuel efficiency, power loss, and exhaust pollutants are all strongly impacted by the piston assembly’s tribological performance. The present study’s primary goal was to develop composite coating by using HVOF process. The composite coating’s characteristics showed a notable improvement, as evidenced by an approximate 12.5% rise in micro-hardness and an 80% decrease in residual stress. A significant reduction in mass loss of the coated sample was also demonstrated by the corrosion test findings, with reductions of roughly 75.2% after 0.5 hours, 53.1% after 1.5 hours, and 42% after 2.5 hours of exposure. After a high-temperature wear test, the mass loss of the as-deposited composite coatings was measured using an electrochemical procedure that contained 3.5 weight percent NaCl for the corrosion test. The present study’s primary goal was to use the HVOF technology to create a composite coating. The composite coating shows 320-380 HV micro-hardness and -10 to -55 MPa residual stress. The present observation is in line increase in the hardness of composite coatings. The production of carbide layers, and the development of oxides on the piston rings are all responsible for the abrupt increase in micro-hardness. Furthermore, as the temperature rises under test circumstances, thermal stress increases but structural stress decreases and compressive stress increases. Consequently, a decrease in residual stress is brought on by a rise in thermal stress.
