3rd Materials Technology Colloquium Chemnitz (19/20 Oct. 2000)
After the success of the first two events in previous years, which focused on modern materials technology and brazing processes, the Materials Technology Colloquium in Chemnitz is well on its way to becoming a good tradition. Proof of this is the increasing number of participants from 81 last year to 134 this year. Participating organisations at the event were: the German Association for Welding and Allied Processes (DVS), the German Society for Materials Science (DGM), the Association for Thermal Spraying (GTS) and the German Society for Electroplating and Surface Technology (DGO). The focus of this year's conference was on the latest development trends in thermal spraying.
Professor Wielage - the patron of the conference - welcomed all guests of honour and participants. Further words of welcome were addressed to the auditorium by Prof. Matthes, the prorector of Chemnitz University of Technology, by DI Heinrich, the managing director of GTS e.V., by DI Satke, the chairman of the Thermal Spraying Working Group and by Prof. Steinhäuser, the chairman of DGO e.V.. The prorector, Prof. Matthes, addressed the general situation at Chemnitz University of Technology, whose focus is now shifting again from the economic and human science directions to the technical directions. With a large number of 2,500 new enrolments this year, the goal of a total of 10,000 students seems achievable.
Prof. Wielege opened the round of scientific contributions with his presentation on developments and trends in thermal spray technology. He gave the participants an overview of the diverse areas of application of thermal spray coatings in the automotive and aerospace industries, medicine, electronics, marine and other industrial sectors. In Germany, for example, thermal spraying is the strongest growth sector in surface technology with an increase of 10%. Taking into account economic and ecological aspects, the integration of thermal spraying into the production process chain represents a major challenge.
Prof. Heberlein, Univ. of Minnesota, spoke about new developments in arc spraying. Modelling of the temperature and velocity distributions in the plane between the wire tips as well as experimental and model investigations of the droplet formation and size distribution were the focus of his contribution.
Prof. Milewski, Inst. for Precision Mechanics, Warsaw, reported on the development of thermal spraying in Poland, whereby his institute played and still plays the decisive role in international cooperation, scientific further development as well as in the transfer of scientific results to industry. He emphasised the great potential of the Polish economy for international cooperation.
In a very lively and practical presentation, Mr. Jansen, AGA Gas GmbH & Co. KG, Hamburg, made all listeners aware of occupational safety when handling technical gases, which is often neglected in everyday life, partly out of habit and partly out of ignorance. Experimental demonstrations illustrated that protective gases do not serve to protect the operator or how vital oxygen can also become life-threatening.
Contributions by DI Beczkowiak, Praxair Tafa, Wiggensbach and DI Horeth, Praxair Services GmbH & Co. KG referred to the production, properties and application range of powders in thermal spraying and to modern plant technology.
In his lecture on computer-aided layer development, Dr Wilden, TU Chemnitz, enthralled the auditorium with his computer animations of the formation of the metal droplets, their transport to the substrate and their spreading and solidification on the substrate.
Further descriptive and interesting technical papers were given on the second day of the event by DI Wank, TU Chemnitz, on the use of thermal plasmas for the synthesis of Si-C-N coatings, by DI Weich, Euroflamm GmbH, on applications of thermally sprayed coatings, by DI Schnick, TU Chemnitz, on thermal spraying of incongruently melting material systems, by DI Hofmann, TU Chemnitz, on the use of themography in defect assessment and coating analysis, by Dr. Nolde, IAG Industrie-Analagen-Bau Georgsmarienhütte GmbH, on thermal spraying in the steel industry, by DI Schwarz, Coatec Gesellschaft für Oberflächenveredlung mbH & Co. KG, on thermal spraying from the user's point of view, and by Dr Ren, Zoz GmbH, Wenden, on high-energy grinding and mechanical alloying of powder.
As part of the 3rd Materials Technology Colloquium, laboratory tours took place, during which the participants learned about the good technical equipment of the Chair of Composite Materials at TU Chemnitz. The HVOF systems Diamond Jet Hybrid (Sulzer Metco) and TOPGUN K (Praxair Tafa) for high velocity flame spraying, the vacuum plasma spraying system, the furnace laboratory, the electron microscopes, the corrosion and wear laboratory and the metallography were visited. In an extensive poster show, the Chair of Composite Materials provided information about its wide-ranging research activities.
At the end of the conference, the mood was generally enthusiastic: there were many opportunities to find out about new development trends and to establish and expand professional connections. Building on the success of the conference, the 4th Materials Technology Colloquium has already been announced, which is planned for next year together with the 4th Industrial Conference on Surface and Heat Treatment Technology (OWT) from 20-21 September 2001 in Chemnitz. At the same time, Prof. Wielage also invited to the conference Composites and Material Composites, which will take place in Chemnitz from 5 - 7 September 2001.
