Waste particles are the huge environmental problem facing today. This paper mainly focuses on utilization of waste particles and aspect of tribology by examining economic, environmental impact on wear loss and coefficient of friction. Aluminium with a different weight fraction of agro (RHA) and industrial (fly ash) waste particulates are fabricated by double stir-casting process. The dry sliding wear behaviour of Al alloy and aluminium hybrid composites for various applied load, sliding distance with sliding speed on wear rate and friction coefficient was conducted by pin-on-disk apparatus. The hypothesis of this study is decreasing the wear loss and coefficient of friction increasing the lifespan of material and also minimising the cost of material. Limited attempts are made on aluminium with waste particles to examine the effect of sliding wear rate. The A356/7.5%RHA-7.5% fly ash hybrid composite achieved higher wear resistance superior to the as-cast alloy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
