发明名称 Piezoelektrisches Bauteil mit Sicherheitsschicht, Verfahren zu dessen Herstellung und Verwendung
摘要 <p>A piezoelectric component with a monolithic stack has piezoceramic layers and electrode layers arranged alternately one on top of the other, at least one porous security layer arranged in the stack for the formation of a crack if mechanical overload of the stack occurs, at least one outer electrode arranged at a lateral surface section for electric contacting of the electrode layers and a plastic sheath of the stack for protecting the stack, wherein the plastic sheath has silicon. The piezoelectric component is characterized in that a coating of the outer electrode, has silicon-free polymer, is arranged between the outer electrode and the plastic sheath. By coating the plating of the outer electrode, the area of the security layer present directly under the plating is protected from silicon component deposits. The piezoelectric component is used for the control of valves, particularly of injection valves of internal combustion engines.</p>
