摘要:
The invention proposes a process for the surface treatment of aluminum in order to produce an electrical contact, and a corresponding component part, wherein an oxide layer on the aluminum surface is removed, for example by etching, in a first step and, in a second step, before an oxide layer is re-formed, the surface is sealed wet-chemically with a conversion layer having metal ions of zirconium or titanium.

摘要:
The invention relates to a diaphragm (1) for an ultrasonic transducer having a diaphragm body (2) which is made of metallic material and is provided on an outer surface region (5; 8) with a coating (10). In order to make it possible for the diaphragm surface to be provided with a particularly damage-resistant coating, the coating (10) has a transparent form such that the surface region (5; 8) of the diaphragm body (2) is visible through the coating (10).

In order to ensure an optimal position of a magnet (3) in relation to a Hall IC (2) or, respectively, its Hall effect elements (4, 5), the magnet (3) and the Hall IC (2) are displaceable in relation to one another and, namely, in the direction of the lateral distance of the two Hall effect elements (4, 5). It is preferred that the Hall IC (2) is retained stationarily in the rotational speed sensor, and the magnet (3) is retained so as to be displaceable and lockable in position, in particular in a base member (10) of the sensor housing.
