Investigation of the transition zone in a joint between high-temperature piezoceramics and metal

摘要

Interaction of materials in a bond between piezoceramics and copper, made through a chromium barrier interlayer, has been evaluated. The blocking effect of chromium on diffusion of bismuth into copper, as well as the value of diffusion of bismuth, which is not in excess of thickness of the chromium barrier layer, have been estimated.
