Özet:

 


In this study, wear behavior of composite
materials produced by mechanical alloying method adding different amounts of B4C
to Al-Graphite matrix were investigated. After adding 2% (vol.) graphite to the
aluminum matrix, 3 different amounts (3%, 6% and 9%) of B4C were
added. The composite powders prepared were mechanically alloyed for 60 minutes.
The milled powders were cold-pressed under 700 MPa pressure. The green compacts
produced were sintered at 600 °C for 120 minutes. The sintered B4C
reinforced aluminum composite materials (AMCs) are characterized by the
scanning electron microscope (SEM+EDS), X-ray diffraction (XRD), and hardness
and density measurements. Wear tests were performed on a standard pin-on-disc
wear testing device with a load of 20 N at a sliding speed of 0.5 ms-1
and four different sliding distances (250-1000 m). As a result of the studies,
the hardness increases as the amount of B4C in the composite
material increases, while the density of AMC decreases. As a result of the wear
tests, the highest weight loss was obtained in the non-reinforced AlGr matrix
alloy, while the lowest weight loss was obtained in 9% B4C
reinforced composite materials. However, it was observed that there was a
decrease in the friction coefficient with increasing amount of reinforcement.
