Summary

High authority piezoceramic actuators incorporate joints in their design. These joints must be stiff to minimize actuation loss between piezoceramic elements yet pliable to survive high frequency cycling. Shear is the anticipated joint failure mode. The effects of joint finish and electrode material on shear strength were evaluated for epoxy-joined piezoceramic specimens. No strength difference due to surface finish was noted for joints with electrodes. Different failure behavior was observed for joints with either air-dried Ag or sputter-deposited Au electrodes. FEM code was developed to model joint performance as a function of constituents, thickness, and shape.
