Influence of Nano-particle on the Wear behaviour of Thin Film Coatings: A Review

Abstract

The current study deals with the friction and wear behaviour of thin film coating used for automotive applications like piston rings, under the influence of nanoparticle like alumina-oxide, copper and many more. The study reports the influence of factors like load and speed under the presence of third body i.e. nano-particle and it has been found that the friction and wear of coatings are determined by adhesion at small load and dominated by adhesion and ploughing at higher load. The shape of particle also affects the wear properties during the test at Pin on disc tribometer. It is found that a small-sized particle can increase the wear of the coating by reducing the friction. These unique tribological mechanisms of the film can help to promote its wide applications in a sand-dust and presence of tiny particle environment.
