Investigation of appropriateness of coated steel piston for aluminium alloy piston for small engines

Materials substitution is imperative research area. The aim of those research are may be the cost reduction,
improved performance on its physical, chemical or mechanical properties like improved strength, reducedweight or in terms of performances. The objective of this paper is to investigate the possibilities to use the steelpiston in place of the aluminium alloy piston for small engine applications like portable generator. Aluminiumalloy piston, uncoated steel piston, nickel coated steel piston and hard chrome coated steel piston considered.Steel pistons plated standard thickness and physically experimented. The thermal analysis like thermaldeformation, total and directional heat flux analysis were carried out in ANSYS software. For the outperformedpiston the CFD analyses on contoured particles carried out with help of ANSYS Fluent software. The CFD
analysis on contoured particles includes
