Abstract
Bu çalışmada, %0,2-0,5 arasında Nd içeren AZ31 alaşımları alçak basınçlı kokil kalıba döküm yöntemiyle üretilmiştir. 400°C’de 4,7 ve 10 m/dk hadde hızlarında paso başına %30 deformasyon miktarıyla saç malzemeler üretilmiştir. Saç malzemelere mikro ark oksidasyon (MAO) yüzey kaplaması yapılmıştır. Farklı miktarda Nd içeren saç AZ31 alaşımlarına ASTM G-133 standardına göre kuru ortamda ileri-geri hareketli aşınma testi uygulanmıştır. Hem Nd ilavesinin hem de MAO kaplamasının saç AZ31 Mg alaşımlarının aşınma direnci üzerine etkisi mikroyapısal çalışmalar ile desteklenerek sistematik olarak incelenmiştir.

Abstract
In this study, in the range of 0.2% to 0.5% Nd elements were added to AZ31 alloys produced by low pressure die casting method. The hot rolling process was applied to these produced alloys at 400 °C with 4,7 and 10 meter per minute rolling speeds at 30% deformation rate per pass. Micro arc oxidation (MAO) were applied to produced alloys. The wear resistance of samples extracted from sheets that have included different surface morphology after various Nd adding were investigated at dry condition according to ASTM G-133 of the standard test method for linearly reciprocating ball-on-flat sliding wear. The effect of MAO coating and Nd addition on wear resistance of investigated alloys was studied systematically on the base of microstructure analysis.
