An Investigation on the Feasibility of Cr2alc Max Phase for Automotive Applications

Abstract

In this thesis, attempts have been made to examine the feasibility of Cr2AlC MAX phase on the aspects of lubrication and thermal management for automotive applications. The Cr2AlC MAX phase was studied as composite coatings, bulk composites, and as a nano additive to improve the efficiency of the engine. The piston ring is the focus area for the composite coating. The formation of tribofilm on the worn surface was analysed by Scanning Kelvin Probe (SKP) measurement of bulk composites produced by hot pressing. Cr2AlC MAX phase as a nano additive was investigated for the piston ring cylinder liner frictional pair for lubrication aspects and thermal management in the engine coolant circuit newline
