Abstract

The adherence and the bond strength of metal-to-ceramic joints are described in terms of the fracture energy Gc and the fracture resistance Kc. Small three- or four-point bend test specimens of 30 to 60 mm length notched or precracked at the metal-ceramic interface are used to determine the Gc and Kc data. Examples of bond strength measurements on metal-to-ceramic joints and plasma-sprayed ceramic layer-metal substrate combinations aim to demonstrate the applicability of the method.
