In automotive engines, piston rings are one of the critical components operating inside the engine keeping the vehicle mileage. The function of piston rings is for better sealing of combustion gases and oil scrapping. With the usage and time, the piston rings wear out. This introduces the need for ring coating of high quality which can operate under high temperature without damaging or peeling off and is also corrosion resistant. The NiP composite coating gives preferable high hardness and improves wear and friction resistance. The good property enhancement of the composite material is also an important factor to be considered. Property of a composite depends on the volume fraction of dispersed phase. In order to achieve good property enhancement, the volume fraction has to be increased. One such technique of achieving this is the plate and bumper method which involves the usage of fixture and is to be moved up and down. The volume fraction achieved in this method is around 8–10%. This method helps in incorporating the particles and achieving a high volume fraction with a slow plating rate. Results shows that considerably the plate and bumper helps in improving the incorporation of composite and contributes more to the mechanical property enhancement of the piston rings.
