Characterization of Aluminium 6013/Red Mud Composite Materials by Salt Spray Test

Composites have been in demand over the last twenty years for their better mechanical properties and corrosion resistance. In this publication, composites fabricated by liquid melt metallurgy techniques using aluminum 6013 as the matrix and red mud particles as reinforcements are subjected to salt spray tests and characterized by salt spray tests. Pre weighed samples of matrix and composites are placed in a salt spray chamber and continuously sprayed with a 5% sodium chloride solution for over 72 hours. Samples were periodically checked for surface damage. Samples were found to show no damage up to 48 hours. At the end of the experiment the damage to the matrix was greater than the composite. Composites are therefore more suitable than matrix alloys for applications where marine environments are present.
