Characterization and Performance Analysis of Graphite and Molybdenum disulphide based Hybrid Composite Materials

Abstract

Abstract An attempt has been performed to observe the influence of heat treatment on composite specimen by dry sliding wear and hardness testing. The particulate reinforcements embedded with AA2218 Aluminium metallic element alloy with 4% constant weight proportion of Graphite, MoS2, with a variable amount of hard reinforcement particulates. Availability of fly ash is abounded and it has to be utilized in any other way. Instead of carbides and nitrides, introducing fly ash as reinforcement satisfies the structural and thermal properties. 5%, 10% & 15% of fly ash added to the composite by liquid scientific discipline route. To get better mechanical properties of composite specimens are treated with ASTM T6 standard. Performance of heat-treated hybrid composite was investigated with a pin on disc with a constant load 2 kg sliding at 300 rpm. Hardness of the specimen at temperature was conjointly measured before and once the heat treatment is completed. The results were compared with base alloy and untreated composite specimens. Heat treated metal exhibits high hardness and wear resistance. This investigation reveals that AA2218 Aluminium matrix composites with high hardness and wear resistance will replace the traditional material employed in automobile elements to get improved performance and longer life.
