ABSTRACT:
A method for determining the adhesion of material layers of any composition on sintered ceramic elements, in particular of material layers on sensor elements for determining gas constituents in gas mixtures. The coated ceramic elements are immersed in an immersion bath consisting of a protic acid, and then subjected to a shock-type heat treatment. Adhesion is then assessed.
