Investigation of Wear and Microhardness Behaviors of AA2196 Matrix Composite Materials Reinforced with Ceramics Produced by Powder Metallurgy Method
Abstract
This study aims to investigate the microhardness and wear properties of AA2196 alloy, one of the new generation aluminum-lithium (Al-Li) alloys, reinforced with single and dual (hybrid) ceramic composites. The produced materials were evaluated to improve their properties. The microhardness and wear tests were conducted to assess the mechanical properties of the materials. The results indicate that the dual ceramic reinforced composite materials with AA2196 matrix exhibit superior performance compared to the single compositions. The 12% reinforced hybrid composite alloy (Alloy13) demonstrated the highest microhardness result, while the 2% and 4% reinforced hybrid composite materials exhibited the highest wear resistance. These findings suggest that the microhardness and wear properties of AA2196 alloy can be enhanced through the use of ceramic composites.
