Literature Overview On Fabrication of Composite Spur Gear

Abstract

Metal Matrix Composites (MMC) are used widely in many areas for engineering. Because of their strength to weight ratio and resistance to wear and high temperature so they were considered as one of the great materials for producing mechanical components for aerospace and automotive industries. We are taking aluminium 6061 metal as matrix and silicon carbide as reinforcement. In this metal matrix composites we are adding magnesium metal powder to the aluminum-silicon carbide molten state. Here magnesium mixed to increase the bonding strength of aluminium and silicon carbide it also increases strength and stiffness of the material. This matrix is produced by stir casting process. To produce the circular blank for gear the treated molten metal is poured into the cavity in the circular die. From the circular blank the teeth were cut by milling process. The strength and durability of both AlSiC MMC and AlSiC-Mg MMC are compared on the test result. Comparing the results, the most effective material is chosen.
