This project is a community project run by the IEPT (Technical University Clausthal) and the IW (Leibniz University Hanover) under the umbrella of the Clausthal Centre for Material Technology. Together, the deoxidation mechanisms during the vacuum soldering of steels are to be elucidated. During preliminary work it was established that the deoxidation behaviour or various steels differs greatly.

In order to be able to optimise soldering processes, a reaction chamber is being built in which the conditions that prevail during an industrial vacuum soldering process can be reproduced. Steel samples prepared in this chamber can be studied without atmospheric contact with their surface composition and finish, and thus enable conclusions to be drawn regarding the influence of temperature during the soldering process. In addition, the influence of various gases is to be studied, and as such plans have been made to reproduce soldering processes in a silane-contaminated low argon vacuum.

All trials are to be conducted in parallel in the reaction chamber in the IEPT and in a vacuum soldering furnace at the IW, with the results to then be compared. Based on the findings, a physical model will be developed that enables predictions for soldering processes.
