Abstract: This work deals with reduction of surface roughness of reciprocating parts of an internal combustion engine and its frictional loss and thereby improving overall efficiency. Surface coatings can be used to reduce surface wear of components. The use of these coatings for engine applications presents a suitable solution to this problem. The materials coated can suddenly show very different properties compared to what they exhibit on a macro scale, enabling unique applications. A major part of the power produced by the engine is lost in overcoming friction between the reciprocating parts. Friction coefficient can be found by the test conducted on Pin on disk apparatus. Before coating bench mark values are taken from uncoated and we compare those valued with values obtained after coating. The technique used for coating is Wire Arc Spray process.
