NiP Composite Coating of Piston Ring
by Plate and Bumper Method
M. Malathi, J. Herbert Mabel, and R. Rajendran
Abstract 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.

1 Introduction
In IC engines, piston rings are subjected to very high mechanical and thermal
stresses, and the durability of the part has to be ensured for maintaining the performance parameters throughout the vehicles’s life time [1–3]. To achieve the durability
with various fuels like gasoline, diesel, CNG, LPG and alcohol fuels, the parts are
