Study on the Behaviour of Surface Wear and Friction for a Pure Aluminium Casting Product Using Permanent Mould

Abstract

Aluminium is a popular choice for structural applications because of its low weight, large specific strength, excellent heat transmission capabilities, and mostly due to its strength-to-weight ratio being high. Any desired shape or form of aluminium may be manufactured using permanent mould casting operation. However, porosity arises as a typical defect where pores cause an increase in surface roughness, which in turn increases wear and friction of the surface and reduces material strength. A variety of porous characteristics on the surface are formed in the casting process by regulating casting pouring parameters like the temperature and velocity of pouring. The presented research establishes a better knowledge of the relationship between the wear and frictional behaviour with temperature and velocity of pouring. In this context, the casting process has been done by creating a three-dimensional model by Ansys Fluent. Observations reveal that the frictional and wear behaviour of pure aluminium increases with the temperature of pouring and reduces with the velocity of pouring.
