The effect of cryogenic treatment on the wear resistance of aluminium alloy LM 25, LM25+5 % fly ash and LM25+10% fly ash composites, which are synthesized by squeeze casting method, was investigated. The impact of the parameters on the wear resistance was studied under two different cryogenic soaking periods [0hrs (untreated), 12hrs and 24 hrs.] and three different load and sliding velocities with the help of pin-on-disc test rig. The wear tests were performed according to Taguchi’s approach. The percentage contribution of the cryogenic soaking period was determined by means of analysis of variance. The load was found to be more significant than cryogenic soaking period and velocity on wear loss of the composites. Regression model was generated to envisage the wear loss.
