Bonding at Metal-Ceramic Interfaces in Hybrid Materials.
Abstract
Mechanical properties of metal-ceramic interfaces were measured at high temperatures. New methods were developed to measure the time and strain rate dependent properties of metal-ceramic interfaces under shear loading and under tensile loading. The shear experiment consisted of depositing a film of the ceramic on the metal and stretching the metal until periodic cracks developed in the ceramic film. Experiments on the copper/silica system demonstrated that these interfaces slide at high temperatures, with a linear relationship between sliding rate and the interfacial shear stress. In tensile experiments, bicrystals of copper and sapphire were loaded in tension.
