Multi component powder injection moulding of metal-ceramic-composites
Mehrkomponentenpulverspritzgießen von Metall-Keramik-Verbunden
Two-component powder injection moulding is a new processing route in powder technology that can be used for the manufacturing of complex shaped metal-ceramic composites in large scale. The following work presents two process variants known from polymer injection moulding (multi component injection moulding and inmould labeling) to achieve a co-sintered metal-ceramic component containing steel 17-4PH and yttria stabilized ZrO2. The chemistry of the metal-ceramic interface is determined by x-ray analysis and electron microscopy respectively. The strength of the joining zone is determined by tensile test. The composition of the metal and the ceramic material was systematically modified to achieve an adjusted sintering shrinkage and a chemical compatibility between both materials respectively.
