Abstract
AbstractIn diesel engine, the loss of power occurs via various means like mechanical losses, cylinder cooling and exhaust from the engine. Frictional losses in diesel engine play a predominant role in mechanical losses. In this study, a chrome plated surface of piston ring material is tested for determining coefficient of friction and specific wear rate of the material against the uncoated surfaced material. The tribological analysis was conducted on pin-on-disc tribotester (ASTM-G99) under the full flooded and starved lubrication condition. The lubricant used for the experimental purpose is the standard 15W40 lubricant used in diesel engine. It was found that the coefficient of friction and specific wear rate (SWR) were reduced by using the chrome-coated piston ring surface as compared to the uncoated surface.KeywordsChrome platingPiston ringCylinder liner
