研究领域

The research interests of Prof. G.J. Kipouros lie in the fields of Materials and Metallurgical Engineering - both in fundamental science and engineering applications, in the field of value-added metallurgy, and in the area of Chemistry and Processing of Materials. Primary interest is the electrochemical engineering of molten salt electrolysis. Specific areas of fundamental research are the thermodynamic, electrochemical and spectroscopic properties of reactive metal halide systems as apply to the production of the metals or coating of the metals. Recycling of reactive metals. Utilization of minerals in metal matrix composites. Metals of interest include the light, refractory and rare earth groups. Electrochemical aspects of copper and nickel production from aqueous solutions. Application of potentiodynamic techniques, cyclic voltammetry and electrochemical impedance spectroscopy in the investigation of passivation and corrosion of materials. A major interest is also the development and processing of powder metallurgy (P/M) light metals alloys as a means to sustainability of parts manufacturing. Modeling of processes used in the production of P/M automotive components as well as study of mechanical properties are areas of interest. Surface engineering and its role in the corrosion protection of reactive metals P/M alloys is examined. Secondary interest in the engineering applications include the development of electrochemical sensors for use in the process control and optimization of high temperature chemical processes. In the area of materials science and engineering the interest is in the study of the chemical stability of the interface between the second phase modification agent and the metal matrix in the composites and powder metallurgy alloys. The application of potentiodynamic techniques, cyclic voltammetry and impedance spectroscopy in the investigation of the corrosion of boride coatings on the sufrace of powder metallurgy alloys. Also the application of the scientific principles in the study and the development of phase-change materials. As a corollary of these studies the electrodeposition of metal matrix composites is also under investigation. The primary value-added metallurgy component of the research explores the potential application of certain naturally-occurring industrial mineral fibres/whiskers/particulates as reinforcement in metal-matrix composites. The use of certain minerals benification wastes as additives to metallurgical processes or as reinforcement in metal-matrix composites are also investigated. A secondary component of the research interests refer to the use of minerals in the development of inexpensive phase-change materials (PCM) for thermal storage.
