Description
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,
