Dry sliding wear analysis of aluminium alloy based cylinder liner by using linear reciprocating tribometer

Abstract

The present research is carried out to develop A6061 based composite for cylinder liner which can improve IC engine efficiency along with a reduction in engine weight. A6061 is reinforced with 2 wt%, 3 wt%, 4 wt% and 5 wt% of vanadium and cobalt filler powder, separately, and their wear behavior is examined. The mechanical characteristics and surface morphology of the composites were also investigated. Taguchi optimization technique with orthogonal array L16 is used for planning of experiments. Filler content, load and reciprocating frequency played major role on wear resistant property. The wear resistance improved with an increase in filler content in case of cobalt filled composite but in the case of vanadium filler, it reduces beyond 4 wt% wt% filler content. A6061 composite with 4 wt% vanadium content is found to have most improved mechanical and wear resistant properties among all the investigated compositions, which could effectively improve engine efficiency and reduce engine weight.
