Resume

Prof. Kure got her M.E. from the Surface Finishing Technology Research Institute of Northeastern University in China and Ph.D. in Hokkaido University in Japan. She had worked in Shenyang Chemical Engineering University, Kansai Research Institute (KRI) in Kyoto, National Institute for Materials Science (NIMS) in Tsukuba, Central Research Institute of Electric Power Industry in Yokosuka, and Mitsubishi Shindoh (Mitsubishi Materials) Co., Ltd in Aizuwakamatsu. Finally, she joined Iwate University as an associate professor in 2012 and then Nagoya Institute of Technology as a full professor since 2017.

Prof. Kure majored in functional surface finishing of various base materials (ferrous metals including carbon steels and stainless steels, non-ferrous metals such as Cu, Al, Ti, Zr, Mg alloys, ceramics and glass, CNT/CNF, graphene, etc.). Her research fields covered broad surface finishing fields including anodizing, electro-plating, electroless-plating, alternating current electrodeposition, sol-gel process, laser irradiation, and RF-sputtering deposition, to achieve versatile metal/alloy and oxide/composite coatings. The functional coating materials can be applied for automotive terminals/connectors, engine parts, electronic devices, anode active materials of lithium-ion batteries, catalytic electrodes of direct ethanol fuel cells, photocatalytic films, perpendicular magnetic recording media, and various components with high electrically conductive coatings for electric vehicles and electrical power supply, as well as high thermal conductive coatings for power devices.     

Abstract

Surface finishing technology of materials plays an essential role in ensuring safety and performance in versatile fields including power electronic devices, automobiles and mechanical equipment, battery and energy conversion, as well as aircraft and aerospace parts. Various electrochemical methods, including electroplating, anodizing, electro-etching or electro-polishing, alternating current plating, as well as electroless plating, are usually used to fabricate versatile metallic and oxide films on various materials for broad industrial applications.

We will introduce several novel electrochemical approaches to fabricate functional nanocomposite films on various non-ferrous materials, e.g., to fabricate Ag(Sn, Cu, Ni)-Graphene composite coatings on copper and aluminum alloys with high electrical and thermal conductivities for automotive terminals/connectors and power electrical/electronic devices (Fig.1a), Al₂O₃/Sn(Ni)-MoS₂ composite coatings on aluminum alloys with enhanced lubricity/wear resistance for engine/transmission parts, TiO₂-TiN(-Sn, MoO_x, MoS₂) composite films on titanium for high-safety anode materials of lithium-ion batteries with large capacity (Fig.1b), and Al(Ti, Mg)-Ni-W-Mo-O-based composite oxide coatings on Ti, Al, and Mg alloys for various transportation/aircraft parts with enhanced mechanical strength and excellent corrosion resistance.
