Investigation on wear behavior of Al6061 hybrid metal matrix composite in braking applications

摘要

The present article investigates the dry sliding wear behavior of Aluminium 6061 hybrid metal matrix composite (ALHMMC) and compare the results with cast iron(ci). The (ALHMMC) possess light weight, low corrosion and high strength which offer unique property, which can use in automobile brakes. The main objective of this work to investigate the sliding wear behavior of al6061 composites reinforce mos_2 particles and to optimize the process parameters in braking applications, the composite were prepared by using stir casting technique and optimization were done by using taguchi technique. The optimal combinations input parameters which will positively influence the wear rate and coefficient of friction. Dry sliding wear test method was used to conduct the experiments by using pin-on-disc wear testing machine, design of experiment was selected for analysis of the data. Investigation about applied load, sliding speed, sliding distance on wear rate and coefficient of friction during wearing process was carried out using ANOVA. results show that applied load has the highest influence followed by sliding distance and sliding velocity.
