Investigating The Lubricated Sliding Wear Behaviour of Aluminium Matrix Composite Produced by Stir – Squeeze Cast Process

Abstract

This investigation makes an attempt to assess the lubricated sliding wear behavior of aluminum matrix composite reinforced with varied weight percent of fly ash particulates as reinforcement using Dimensional Analysis. Through this analytical modeling, the input parameters & the process outcome are linked through an expression so that the wear behavior of the composite under lubrication can be predicted without conducting actual trials for any arbitrary values of the inputs. The produced base metal & composite specimen were subjected to lubricated sliding wear test & were compared with the theoretical wear values generated through analytical modeling using dimensional analysis and the regression equation obtained by Minitab -17 statistical tool to justify the validity of the models. Further validation trials were carried out for the intermediate process variable values and the results of validation trials were justified through R- Tool program.
