Frictional Behavior of Aluminium MMC Foam Synthesized Using Dual Foaming Agent

Abstract

In the present article, an attempt is made to develop aluminium foam indigenously. The experimental setup for the production of aluminium foam is designed and fabricated. Investigation are made into the use of dual foaming agents (i.e. TiH2 and CaCO3) along with SiC to develop suitable aluminium foams which can be utilized for various engineering products like load-bearing elements, crash resistance elements etc. The process is standardized to produce aluminium foam with specific density with minimum variability. This aluminium foam produced possesses a very low coefficient of friction. This work successfully characterized the frictional properties of the developed material. In order to define the Frictional properties of this material, a mathematical model which uniquely defines the frictional behavior of this modified Al-MMC foam has been developed.
