Microstructural analysis of Al-SiC composites fabricated through centrifugal casting process

Abstract

This paper describes the fundamental needs of the centrifugal casting (CC) process. It is widely popular in foundries because of its simplicity and characteristics. CC is called as if the casting is produced with the help of the centrifugal force developed by the mould rotation. The true centrifugal casting (TCC) process is suitable for making hollow pipes, in which the centrifugal force provides good adhesion of molten metal on the mould’s wall. From the literature, CC is a method for the production of bulk functionally graded materials (FGMs). Many kinds of research have been done on the CC process and some of the results have been discussed here. In the case of FGMs by CC, the gradation of harder particles with higher density was found in the outer region because of the centrifugal force, according to this gradation and the transition of materials, the mechanical and wear properties are changed from one place to another place along the specimen. For this phenomenon, the CC process is suitable for the production of automobile components. This paper provides the baseline knowledge about CC in classification, process variables and the characterisation, advantages and applications, and CC uses in research.
