The Effect of Ceramic Oxide Type on Compressive Strength and Abrasive Wear Behavior in Different Ceramic Oxide Reinforced Al2024 Composites

Abstract

In this study, particulate tungsten trioxide (WO3), Neodymium oxide (Nd2O3), zirconium oxide(ZrO2) and aluminum oxide (Al2O3) ceramics were separately reinforced at 10% weight ratio into 2024aluminum matrix material by powder metallurgy method. Abrasive wear and compression strength testswere carried out on the composite samples. According to the data obtained, the type of ceramic oxidereinforcement in the composite structure was compared according to the wear behavior and compressivestrength. As a result of the abrasive wear tests carried, the lowest wear loss amount was obtained from theAl2O3 reinforced composite, while the highest wear loss value was obtained from the WO3 reinforcedsample. Looking at the compressive strengths, it was seen that the highest compressive stress was obtainedfrom the Al2O3 reinforced composite, while the lowest compressive stress value was obtained from theNd2O3 reinforced sample. It was understood that the hardness values of the ceramic oxides doped into theAl2024 matrix directly affect the wear loss and compressive strength values of the composite structures. Itwas concluded that WO3, Nd2O3, ZrO2 and Al2O3 reinforcement elements in the form of particles dopedinto the Al2024 matrix improve the mechanical properties of the composite structure.
