Investigations on mechanical behaviour of nano zirconium oxide and graphite particles reinforced copper-tin alloy metal composites

Abstract

Due to its fundamental mechanical qualities, copper matrix composites (CMC) with reinforcement of graphite (Gr) and nano zirconium oxide (ZrO2) are a more popular composite material for applications in the automotive, aerospace, and marine industries. The properties and quality of the composite material are directly impacted by how difficult it is to distribute reinforcement uniformly throughout the matrix. In the present study, ZrO2 and Gr particles are used to strengthen Cu alloy composites, and their microstructure and mechanical behaviour are examined. In this study, the mechanical characteristics of an alloy consisting of 90% Cu and 10% Sn were compared to various nano ZrO2 and graphite particle compositions. SEM and EDS were used to conduct microstructural study of the mechanical parameters such as hardness, tensile strength, and particle dispersion in matrix composites with reinforcement. After testing, it was discovered that hardness and tensile strength of the composite Cu-Sn alloy with ZrO2 mixture were greater than copper alloy matrix.
