The requirement for lightweight, high-performance materials with higher wear
resistance, which is critical in industries such as aerospace, automotive, and
consumer-related sectors, has fueled the development of particle reinforced
metal matrix composites (PRMCs). These materials are an appealing alternative
for a broad variety of scientific and technological applications due to their
remarkable mechanical qualities and low cost. The primary goal of developing
metal matrix composite materials is to combine the favorable properties of
metals and ceramics. This study included several experimental experiments to
explore the behavior of stir-cast composites made of aluminum grade 6063 with
varying amounts of SiC, Al2O3, and TiO2 reinforcements. The specimens obtained
through the use of stir casting methodologies are subjected to a wide range of
mechanical tests, including tensile tests, impact analyses, hardness
measurements, and tribological investigations such as sliding wear tests and
erosive wear tests. The existence of phases inside the reinforced material was
determined using X-ray diffraction. The testing findings showed that the
integration of silicon carbide particles resulted in improved mechanical
properties owing to the particles' uniform distribution. Many variables impact
the properties of metal matrix composites (MMCs), including the interface
characteristics, the volume fraction of reinforcement, and the material
selection. The Al MMC's tribological metrics show a decrease in both the
coefficient of friction and the wear rate. The experimental findings show that
semi-ductile behavior exists in composites with a high erosion rate. The
aforementioned composite materials may find use in the aerospace and automotive
industries, where increased properties like as toughness, wear rate, density,
and hardness are desired. Nonetheless, these findings may serve as a foundation
for the creation of MMC components by both academics and industry designers. The
ductility test results show that the incorporation of reinforcement particles
(SiC-Al2O3-TiO2) in the matrix material of Al 6063-(SiC-Al2O3-TiO2) composites
reduces ductility significantly.
