Advanced technologies for the preparation of coatings containing complex metallic alloys — •Constantin Vahlas¹ and Witold Gulbinski² — ¹Centre Interuniversitaire de Recherche et d Ingenierie des Materiaux (CIRIMAT-CNRS), Toulouse, France — ²Physics Department, Faculty of Mechanical Engineering, Technical University of Koszalin, Poland

The development of advanced technologies for the processing of CMA-based coatings presents a major interest for numerous application domains. Indeed such technologies are widely recognized to be key underpinning and critically enabling areas of R&D on which most industrial sectors and fields of technology application, directly or indirectly depend. The presentation will introduce the state of the art in this field and the projected research within the CMA Network of Excellence. The use of selected PVD and MOCVD techniques will allow for processes and materials optimization with regard to the aimed application (e.g. hard and/or low friction coatings). To face problems arising from the multi-element nature and the often extremely narrow composition domain of CMAs, multisource coating methods as an alternative of deposition from alloy targets, and selected combinations of organometallic precursors will be studied. Dedicated reactors, appropriate operating conditions, state of the art diagnostics and characterization techniques will also be investigated.
