Quality assurance plays a central role in surface technology. Therefore, production-integrated quality assurance concepts and test methods are being developed at Fraunhofer IFAM which allow stable process control. The new requirements for quality assurance resulting from the trend towards digitalization in manufacturing are also taken into account. In addition, the institute has accredited testing facilities that are also used for failure analysis. Topic-specific training courses and regular technology transfer to industrial practice complete the core competence of surface technology.
