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 2024 aluminum matrix material by powder metallurgy method. Abrasive wear and compression strength tests were carried out on the composite samples. According to the data obtained, the type of ceramic oxide reinforcement in the composite structure was compared according to the wear behavior and compressive strength. As a result of the abrasive wear tests carried, the lowest wear loss amount was obtained from the Al2O3 reinforced composite, while the highest wear loss value was obtained from the WO3 reinforced sample. Looking at the compressive strengths, it was seen that the highest compressive stress was obtained from the Al2O3 reinforced composite, while the lowest compressive stress value was obtained from the Nd2O3 reinforced sample. It was understood that the hardness values of the ceramic oxides doped into the Al2024 matrix directly affect the wear loss and compressive strength values of the composite structures. It was concluded that WO3, Nd2O3, ZrO2 and Al2O3 reinforcement elements in the form of particles doped into the Al2024 matrix improve the mechanical properties of the composite structure.
