PERFORMANCE PARAMETER WITH COATING AND SURFACE TEXTURING ON PISTON RING: AN OVERVIEW

Reducing the energy consumption and exhaust emission, and improving the combustion efficiency of internal combustionengine are important for solving the problems of climate change and environmental pollution. The piston ring-liner systemis one of the most serious friction pairs in internal combustion engine, accounting for 26% of the total friction loss. This review paper explores various experimental techniques, coating materials, and texturing methods applied to piston rings. The aim is to enhance the performance, wear resistance, friction reduction, and overall durability of piston rings used in internal combustion engines. The study highlights different coating technologies such as thermal spraying, DLC (Diamond-like Carbon), and ceramic coatings. Additionally, it discusses various surface texturing techniques, including laser texturing and micro-machining, for optimizing the tribological performance of piston rings.
