A compression ring may be a metal seal between the pistons and cylinder walls in a combustion chamber of Internal combustion engine, the important function of the compression ring is to cover the combustion area in order that there’s no movement of gases from the engine chamber to the crank case area. Supportive heat transmission from the piston to the cylinder wall helps in achieving the specified power exerted at the piston crown and efficiency of an engine. This compression ring is continuously subjected to friction and wear. To overcome or decrease the wear and tear it’s coated with certain materials which rises the lifetime of the ring. In this project we are using Chrome and Moly coated piston rings. The Coating thickness were measured using Image Analyzer. The Pin-on-Disk (POD) testing machine used to find the wear and tear rate of Chrome and Moly coated piston rings. The results obtained from the test were studied for optimum piston ring coating and found that the moly coating shows greater resistance to wear compared to the chrome coating as per the obtained results from the pin on disk equipment
