Abstract
It is essential to develop an innovative type of material for improving the mechanical and tribological properties from the existing one in the field of materials. New developments are focussed not only to improve the above said properties of materials, also to have contradictory combinations of properties. Functionally graded material (FGM) is one that will be providing solution to upcoming applications. In this paper, fabrication of FGM using centrifugal casting method is discussed. This method is widely used, because of its commercial viability and less technology requirements, compared to other methods of fabrication. A centrifugal casting setup is fabricated to develop FGM parts. Technical considerations in designing of centrifugal casting setup highlights the problems encountered and considerations while fabricating it. Influence of parameters like processing temperature, cooling rate, particle size, density and rotational speed of mould, on fabrication of centrifugally cast part are discussed, to understand their effect in modifying the properties of materials. With improved properties and their combinations, FGMs satisfy the needs across various applications such as biomaterials, aerospace, thermal barrier coatings, which are growing further and few applications where it is being used are deliberated.
