Abstract

The need to improve the mechanical and electrochemical performance of aluminum alloy for extended application is the motivation behind this present work which is the inoculation of TiO2/SnO2 composite particulates on A500 by stir casting route. The effect of Ti/Sn on A500 aluminum series on the properties and microstructure of the produced alloy were investigated. The TiO2/SnO2 was varied from 5 to 10 wt.%. The microstructural properties of these sequence alloys were investigated using scanning electron microscopy coupled with energy dispersive spectroscopy, and X-ray diffraction. The corrosion degradation properties in 3.65% NaCl solution were studied using linear potentiodynamic polarization technique. The wear and hardness of the composite-induced aluminum alloy were measured with dry abrasive MTR-300 testers and high diamond microhardness tester, respectively. The results showed that the average hardness value of 42.56 and 65.5 HV and wear loss of 1.5 and 0.5 g were obtained for the 0% and 10 wt.% TiO2/SnO2 in A500 series. Hence, the addition of TiO2�SnO2 led to the precipitation and modification of complex intermetallic particles like Al2SnTiO and AlSiSn which also indicate a fairly good interfacial interaction. This outcome has established that up to 10 wt.% particulate on A500 aluminum can be used in enhancing the tribology,
