Experimental Analysis of Residual Stress, Micro-Hardness and Corrosion Behavior of HVOF Sprayed Composite Coating
Abstract: 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 …
