Abstract : In this study, 0.25 wt.% Multi-Wall Carbon Nanotube (MWCNT) reinforced magnesium matrix composites were
synthesized by semi-powder metallurgy technique. Uniform distribution of MWCNT and improvement of hardness and wear
performance were aimed at this work. Unreinforced AZ91 magnesium alloy and MWCNT reinforced composite were
fabricated in hot press test device. Argon atmosphere was used to prevent oxidation due to having poor oxidation resistance
of magnesium and its alloys. Scanning Electron Microscope (SEM) and X-ray Diffraction (XRD) were used to characterize
of the present phases and microstructure. Tribological test was conducted by reciprocating apparatus integrated with
tribometer test machine. Different loads (5N, 10N, 20N and 40N) were applied in dry sliding conditions. Based on the
results, hardness behavior is improved about 10% with the addition of MWCNT. Samples have free of microstructural
defects according to the SEM results. MWCNT reinforced sample has also lower wear rate than unreinforced magnesium
alloy.
