Advanced Joining

Advanced joining technology aims at creating joints which can withstand harsh operating conditions (e.g. high temperatures, high or complex mechanical loads, corrosive environments), or joints in which the material interface assumes specific functional properties (e.g. thermal management functions). To achieve these goals, the joining process must be considered as an integral step of the manufacturing process. Our research is directed at understanding the complex relationships between all manufacturing steps (incl. the joining process), the microstructural evolution of the materials, and the resulting properties of the joined assembly. In particular, we focus on investigating dedicated interlayer and coating systems for material surface and joint interface engineering, and on exploiting nanoscale phenomena for novel joining concepts (e.g. → nanomultilayers and nanopastes for joining). By combining our expertise in joining technology and in corrosion management, we develop new joining solutions for the current and future needs of the industry (→ our services).
