7th European Conference on Tribology in conjunction with the special event - 4th Austria-India-Symposium on Materials Engineering and Tribology The European Conference on Tribology 2019 (ECOTRIB 2019) is the seventh in the series of this biennial Conference events primarily focused on the economy and industrial landscape of Central and South Europe. This conference will be organized in Austria by the Austrian Tribology Society in cooperation with the Austrian Center of Competence for Tribology (AC²T) and the TU Wien (Technische Universität Wien) and the ECOTRIB partners: the Italian Tribology Association, the Slovenian Society for Tribology and Swiss Tribology. It is the prominent challenge for tribology and tribologists to cope with the actual tasks of technological development considering both the economic situation and the ecological needs as addressed by the acronym of the conference. ECOTRIB 2019 will provide an international forum for researchers from industry and academia to discuss the latest research approaches and results in tribology as well as recent applications concerning reduction of wear, controlling of friction and enabling reliable function of technical systems. Conference language will be English. Austria-India-Symposium Materials science is an essential scientific field for the economic and ecological optimization of products and production processes. Wherever two parts move relative to one another, and thus the interaction between the system elements are relevant, tribological knowledge, regarding friction, lubricant application and wear, is necessary to solve the requirements. Thus materials science and tribology are closely linked together. Austria has a long tradition in product and process development, but a very small national market. India is a fast growing market with a huge demand on products and a fast increasing number of well-educated young scientists. The aim of this event is to address challenges where knowledge in Tribology and Material Sciences are important tools to solve industrial requirements in India and Austria and to bring together scientists and experts from companies of both countries.
