Effect on the mechanical properties of Za-27/graphite reinforced composites when routed through a squeeze casting process

Abstract

Zinc Aluminium Alloy with a presence of the alloy number of 27 is widely being used in the production as well as in the manufacturing of roller bearing and bushes mostly in the auto industry by replacing the bronze made bearings due to its low cost value along with the utmost best performance. And as an add-on, Zinc Aluminium Alloy 27 is a highly strengthened alloy with best metallurgical characters which is somewhat on the high side in the graph when relating it with other types of commonly utilized cast aluminium alloys. The current research work deals purely with increasing the mechanical characteristics of ZA 27 alloy and also to identify the characteristics of the similar alloy when it combines with a metal matrix composites that has been reinforced with the graphite which is purely produced by squeeze casting technique. With respect to this, the reinforced graphite and the Za 27 mixture increases the heat expansion and expands the autonomous lubrication property. The result of this research reveals about the input process parameter increase and then there will be a relevant improvement in its ductile character but with response to the rise in mass of the graphite particles, which will lead to the decrease in the mechanical property such as hardness.
