Aluminum matrix composites (AMCs)
have evolved into a special field of materials science and
engineering by becoming a premise for consistent
research due to their excellent strength, low density,
improved wear resistance, and enhanced thermal
properties. The essence of AMCs lies in their ability to
offer countless opportunities to tailor material properties
as per the design requirements. In the current
investigation, AMC has been synthesized by
incorporating titanium diboride (TiB2) particles into pure
aluminum melt adopting liquid state processing route.
AMCs containing 3, 6, 9, 12 and 15wt.% of TiB2 were
obtained by varying the reinforcement content.
Metallographic and tribological studies were conducted
on the as-cast AMCs. Microstructural observation shows
a homogenous distribution of TiB2 particles into the
aluminum matrix. A pin-on-disc tribometer was used to
evaluate the dry sliding behavior of the AMC under
varying load and speed at a constant sliding distance. The
obtained results show an improvement in the wear
behavior of AMC in contrast to unreinforced aluminum.
The addition of TiB2 plays an important role in enhancing
the tribological properties of AMCs. The details
presented in the current work encourage researchers to
shift concentration from conventional metals and alloys
to AMCs which offer superior wear properties.
