HiPIMS: technology, physics and thin film applications

HiPIMS (high power impulse magnetron sputtering) is the topic of one of our invited speaks, which will be addressed by Professor Tiberiu Minea from the Université Paris-Sud, Laboratoire de Physique des Gaz et des Plasmas (France). Minea holds a PhD in Plasma Physics from that French university. He is the president of the French Federation of Scientific Societies, which groups the Physical, Optical, Electronics and Electro-technics, and Vacuum societies. He is also the president of the Scientific and Technical Committee at the French Vacuum Society. He authored/co-authored 67 articles in peer-reviewed international journals, 2 book chapters and 2 international patents; advised 11 doctoral theses and presented 16 invited speaks in conferences.The magnetron technology is worldwide used for thin film deposition since the late 1960s and it becomes over the years the standard for Physical Vapor Deposition (PVD). During the last decade, the development of HiPIMS has emerged as a promising alternative to improve the quality of the deposited films. HiPIMS takes advantage from the significant ionization of the sputtered material being one of the ionized PVD technologies.In our symposium "Surface Engineering - functional coatings and modified surfaces", Professor Minea is going to talk about the technology, physics and thin film applications on HiPIMS.

Mechanical, thermal, and electronic properties of transition metal dichalcogenides.

Our invited speaker Christopher Muratore is the "Wright Brothers Institute Endowed Chair Professor" at University of Dayton, Department of Chemical and Materials Engineering (USA). He holds a BSc in Metallurgical and Materials Engineering (1999) and a PhD in Materials Science and Engineering (2002), both from Colorado School of Mines (USA). In the past, he worked for the Air Force Research Laboratory and was a postdoctoral fellow at the Naval Research Laboratory. The papers he authored or co-authored have more than 1.090 citations.

In the American Vacuum Society (AVS), Muratore has held executive positions and coordinated meetings and projects. He has carried out editorial activities as a guest editor for Thin Solid Films and Surface and Coatings Technology. He was honored by Air Force Research Laboratory (Cleary Award Finalist, 2010), the American Vacuum Society (Bunshah Award, 2003), and the McQuiston Fellowship (2001).

In our symposium "Surface Engineering - functional coatings and modified surfaces", Professor Muratore is going to talk about mechanical, thermal, and electronic properties of transition metal dichalcogenides (TMD), such as molybdenum disulfide (MoS2). These remarkable two-dimensional layered semiconductor materials are ubiquitous space lubricants and have many other unique characteristics. During his talk, Muratore is going to present a demonstration of TMD thin films growth on diverse substrates by novel vapor phase techniques, in particular an ultra-high vacuum (UHV) physical vapor deposition (PVD) process. Muratore will also share with our audience the excellent properties of the obtained TMD films, grown up to several square centimeters, as well as his investigations relating to the application of these materials in thermoelectric devices.

Tribologia de motores flex-fuel

No Simpósio N do XIII Encontro da SBPMat (João Pessoa, 28 de setembro a 2 de outubro), Amilton Sinatora, professor titular da Escola Politécnica da USP, compartilhará com os participantes desafios e resultados do consórcio Triboflex. O consórcio reúne empresas do setor automotivo e universidades com o objetivo de aumentar o entendimento dos fenômenos relativos ao desgaste, atrito e lubrificação em motores flex-fuel que utilizam etanol e gasolina. Além de apresentar resultados técnicos obtidos até o momento, Sinatora abordará dificuldades e soluções encontradas na gestão do consórcio.

Amilton Sinatora é engenheiro metalurgista pela Escola Politécnica da USP (1975) e mestre e doutor em Engenharia Mecânica pela Unicamp (1986 e 1990, respectivamente). Fez pós-doutorado na Ruhr Universität Bochum, na Alemanha. Foi gerente de Inovação e Tecnologia da Villares Rolls, empresa produtora de cilindros para laminação. É bolsista de Produtividade em Pesquisa do CNPq - Nível 1B.

Pesquisa desgaste e atrito em componentes mecânicos bem como as formas de controlá-los. Nestes temas e em temas correlatos, orientou 20 dissertações de mestrado e 12 teses de doutorado. Coordena projetos de pesquisa e inovação com empresas dos setores de mineração, metal-mecânico e automotivo por meio do projeto TRIBOFLEX.

Dia 30 de setembro (terça-feira) às 9:30 hs., no Centro de Convenções de João Pessoa - room 2

Thin films seen in the light of high energy synchrotron radiation: stress and microstructure analysis using energy-dispersive diffraction.

Our invited speaker Professor Christoph Genzel is head of the Department of Microstructure and Residual Stress Analysis at the Helmholtz-Zentrum Berlin für Materialien und Energie (HZB), in Germany. At HZB he is also the deputy head of the Institute of Applied Materials, where he coordinates a group of diffraction and scattering. Besides, Genzel is Associate Professor at the Technische Universität Berlin.

In our symposium "Surface Engineering - functional coatings and modified surfaces", Professor Genzel is going to present his talk about stress and microstructure analysis of thin films using energy-dispersive diffraction. Genzel will demonstrate that (contrary to a widespread opinion) high energy synchrotron radiation and thin film analysis may "fit together". Genzel will share with our audience the corresponding experiments he performed on the materials science beamline EDDI at BESSY II, which is one of the very few instruments worldwide that is especially dedicated to energy-dispersive diffraction.

At Humboldt-Universität Berlin, Professor Genzel completed his Diploma thesis in crystallography (X-ray diffraction), his Doctoral thesis in X-ray topography (1984) and his habilitation in X-ray residual stress analysis. He has large professional experience on diffraction methods using high energy synchrotron X-rays, neutrons and laboratory X-rays; depth-resolved analysis of residual stress, microstructure and texture by angle and energy-dispersive diffraction, and in-situ analysis of stress and microstructure evolution under service conditions.
