Özet
The conversion into the desired shape of the metal powders using Powder Metallurgy (PM) method
enables economically mass productions. This case allows producing parts with complex and high
dimensional accuracy with no machining. In this study the composites and hybrid composites with Al
matrix were produced using PM method with different ratios B4C and SiC. Microhardness and wear
experiments of the produced composites were investigated. Wear experiments were performed at a
constant speed of 0.5 m/s, application loads of 5, 10 and 15 N and sliding distances of 250, 500, and
750 m. Then, SEM images of composites and hybrid composites were captured. The increase of the
reinforcement ratio in the composites contributed to the increase of the hardness. The highest
hardness value was computed as 58.7 HV from 16% B4C reinforced composite. In addition, the
increase in the reinforcement ratio contributed to the increase of the wear resistance. The increase
in the load and sliding distance also increased the wear. The minimum weight loss was calculated as
18 mg from 5 N load, 250 m sliding distance and 16% SiC reinforced composite.
