A method for determining the adhesion of layers of a ceramic sensor element for detecting at least one property of a measurement gas in a measurement gas space

摘要

It is a method for the determination of the adhesive strength of layers of a ceramic sensor element (10) for detecting at least one property of a measurement gas in a measurement gas space, in particular for the detection of a portion of a gas component in the measuring gas or a temperature of the measurement gas, is proposed. The method comprises introducing a ceramic sensor element (10) with a layer structure (12) of a plurality of layers in a first immersion bath (40) with a first protic solution (42), introduction of the coated ceramic sensor element (10) in a second dip bath (44) with a second protic solution (46), wherein the first protic solution, and the second protic solution (46) are selected in such a way that a precipitation reaction takes place, in the case of a salt between the layers and / or within the ceramic sensor element (10) fails, thermal treatment of the sensor element (10) and checking of the sensor element (10) to damage to the layers.
