Entwicklung von Metallisierungs- und Fuegeverfahren fuer Al_2O_3-Dispersionskeramiken mit dem Ziel der Anwendung in der Verschleissschutz- und Elektrotechnik/Elektronik Abschlussbericht

A systematic investigation on the reactive brazing technique resulted in a suitable joining technology for Al_2O_3 dispersion ceramics (ADC). By application of different reactive solders ADC-CrNi steel and ADC-copper joints are obtained by a single-step process without preceding metallizing. Performance of brazed joints determined in bending tests corresponds with ADC-wetting behaviour of the reactive solders as determined by in vacuo tests. Fracture toughness of the ADC/reactive solder joints largely depends on the duration of the brazing process. Besides the vacuum stove technique, also induction brazing can be applied to the preparation of ADC-steel joints.
