Abstract (en)
The method involves generating ultrasonic signals by a diaphragm that includes a diaphragm base (4). A surface coating is coated on the base, where the surface coating includes a chromium layer (20). A nickel layer (18) is a multi-layer and is arranged between the base and the chromium layer. The thickness (26) of the base and the thicknesses (22, 24) of the layers (18, 20) of the coating are influenced such that a given resonance frequency of composite materials is adjusted by the base and the layers. A layer of the nickel layer is galvanically coated using a sulfamate electrolyte. An independent claim is also included for an ultrasonic sensor.
