Effect of Quenching Media on Corrosion Resistance of Al-Si-Mg Alloy
Abstract
This study aims to preparing of Al-Si-Mg alloy and study the effect of quenching
media (polymer solution and water) on the properties of prepared alloy such as corrosion
resistance in 3.5% NaCl , surface roughness and microstructure. Also study the effect of
addition alloying elements (Boron and Titanium) on above properties of prepared alloy.
The results showed that improvement in corrosion resistance and surface softness of
prepared alloys when addition of boron and titanium to the prepared alloy and when
quenched in polymer solution. Optical microscopic results showed that the
microstructure of prepared alloys when quenched in polymer solution consists of shape,
size and uniform distributing for grains in comparison with the same alloys when
quenched in water.
