In this present study, three insitu
composites have been produced with different
reinforcement of Al3Zr, ZrB2 and Al3Zr+ZrB2 in
AA5052 alloy matrix by direct melt reaction (DMR)
technique. These composites were characterized by
XRD for phases present, for morphology under SEM.
Mechanical properties have been evaluated in detail and
tribological properties have been studied under dry
sliding wear conditions for all composites for different
variables such as sliding distance and applied loads.
XRD and SEM results show the successful formation of
reinforcements. The mechanical and wear test results
shows that Al3Zr+ZrB2 reinforced AA5052 composite
has the superior mechanical properties and wear
resistance among all composites. This composite could
be a suitable substitute for existing materials for
applications related to automobile, aero-space and
marine applications.
