Evaluation of copper chill on tribological behaviour of LM13/ZrSiO₄/C hybrid metal matrix composites

Abstract

Composites place a vital role in applications of material science I,e aerospace, automobile, marine, etc... Dual reinforcement composites are a trending research area in the field of metal matrix composites. In this research article dual reinforcement i.e zirconium silicate and carbon are added to molten LM13 using the stir casting process in terms of (3+3), (6+3), (9+3) and (12+3) wt.% respectively using copper as a chill kept toward one end. Tensile, hardness, and microstructural studies are done on the composite specimen at the chill end and non-chill. It is found an increase in reinforcement and chilling effect increases the properties of the composite.
