|Title:||Optimization of magnetic and electrical properties of new aluminium matrix composite reinforced with magnetic nano iron oxide (Fe3O4)|
|Abstract:||The utility of new permanent magnetic materials and their continual improvement became an attractive area for the academic and industrial partners. In the modern technology, there is no scene of permanent magnet applications decaying in near future. Naturally, there are optimistic prospects for innovative applications, especially if the properties of cost-effective magnetic pieces can be manufactured to new requirements such as corrosive and wear stability and/or high temperature applications, etc. Today, permanent magnets are unique in their capability to deliver magnetic flux into the air gap of a magnetic circuit without any continuous expenditure of energy. Aluminium matrix composite materials are used in aeronautical, aerospace, defence and automotive applications especially in the thermal management areas. Aluminium Matrix Composites (AMCs) reinforced with Nano Iron Oxide (Fe3O4) exhibit good physical and mechanical behaviour (electrical conductivity and magnetic permeability), which makes it an excellent multifunctional lightweight material. In the frame of this present work, low cost-effective permanent magnetic composites are proposed by using Aluminium Matrix Composites (AMCs) reinforced basically with Nano Iron Oxide (Fe3O4) and also addition of other reinforcement alloying elements such Nickel Oxide (NiO) have stabilized the structure. As for magnetic iron oxide, it is very easy to produce as nanoscale particles that were presented in the former papers. Magnetic iron oxide nanoparticles (Fe3O4) with a lattice parameter 0.8397 nm are very adaptable for new electromagnetic applications. Cost reduction can be obtained by reducing the total raw material cost as well as more efficient manufacturing and assembly. Electromagnetic applications such as electric motors, fast switching actuators or inductor cores for power electronics. As well-known pulse transformers (e. g. ignition systems) operate in high and transient magnetic fields. High resistivity products have specifically been developed to maintain low eddy-current losses in large cross-sections. Owing to the good magnetic and electrical properties, magnetite iron oxide (Fe3O4) is one of the favored and paramount characterized filler materials. The present paper is based on low cost manufacturing of light and efficient materials for aeronautical and automotive applications by creating these new type of composites based on aluminium matrix (AMCs) reinforced with Magnetic Nano Iron Oxide|
