Abstract

In this paper, the performance evaluation of aluminum alloy, their microstructural and mechanical properties associated with the change in induced composite particles were studied. The influence of TiO2.SnO2 metal composite in the range of 5-10% wt as inoculant on Al-Mg-Si series alloy and its corrosion resistance mechanism has been explored by liquid metallurgy and investigated in 3.65% NaCl solution using linear potentiodynamic polarization technique. The composite alloyed compositions and phase change were determined with (SEM/EDX and XRD). The surface structure of the alloy samples shows that TiO2.SnO2 particles were dispatched along the interface. The addition of TiO2.SnO2 to the alloy led to the precipitation and modification of complex intermetallic particles like Al2SnTiO and AlSiSn which also indicate a fairly good interfacial interaction. This phase orientation further reduces the possibility of corrosion penetration within the intermediate. It was found that the addition of dispersed composite in the melt provide feasible improvement on the hardness behavior.
