Chapter 23 Mechanical and Tribological Performance of Aluminium Matrix Composite Reinforced with Nano Iron Oxide (Fe3O4) E. Bayraktar, M.-H. Robert, I. Miskioglu, and A. Tosun Bayraktar Abstract Aluminium matrix composite materials are used in aerospace, defence, automotive applications especially in the thermal management areas. Aluminium Matrix Composite (AMCs) reinforced with Nano Iron Oxide (Fe3O4) exhibit good physical and mechanical behaviour (electrical conductivity and wear resistance), which makes it an excellent multifunctional lightweight material. The present paper is based on low cost manufacturing of light and efficient materials for aeronautical applications. To that end, a study has been carried out on an aluminium matrix composite reinforced with Fe3O4-iron oxide and other alloying elements produced in our laboratory. Micro indentation tests were conducted on the AMC to investigate its elastic modulus, hardness, and scratch tests with very long cycles were performed to study its wear performance. Scanning Electron Microscopy examinations were made to study the morphology of damage surfaces. The goal was to get more information about the influence of fillers on the corresponding reinforcing and wear mechanism.

More recently, particulate reinforced MMCs have attracted considerable attention as a result of their relatively low cost and characteristic isotropic properties. Randomly reinforced aluminum metal matrix composites are a class of composite materials having trendy properties like low density, high specific stiffness, high specific strength, controlled coefficient of thermal expansion, increased fatigue resistance and superior dimensional stability in different environmental conditions (high temperatures etc.) [1–8]. These materials have appeared as a vital class of advanced materials providing engineers the possibility of tailoring the material properties to suit their needs [1, 3]. The particulate reinforced MMCs differ from the conventional engineering materials in that the structure and properties of these materials can be optimized by various processing techniques that have been improved over the last two decades. The processing methods utilized to manufacture particulate reinforced MMCs can be grouped based on the temperature of the metallic matrix during processing. In the frame of the research project going on, this present work aims to evaluate certain parameters of the aluminium matrix composite (AMC) reinforced with nano iron oxide (Fe3O4) that we have recently designed by a simple and a low cost manufacturing technique [1, 2].
