Abstract
A layer system for electrochemical probes has a ceramic substrate, electrodes applied on the ceramic substrate, a sensor layer arranged over the electrodes, and a structure for improving adherence of the sensor layer to the substrate and including at least one adherence improving layer portion which is located under and extends upwardly into the sensor layer and also is sintered with the substrate.
Claims18
A layer system for a semi-conductor resistance measuring sensor, comprising a ceramic substrate;
- electrodes applied on said ceramic substrate;
- a sensor layer arranged over said electrodes;
- and means for improving adherence of said sensor layer to said substrate, said means including at least one adherence improving layer portion located under and extending upwardly into said sensor layer, said at least one layer portion extending along at least one of said electrodes and also sintered with said substrate, said at least one layer portion being composed of a material which has at least one layer portion being composed of a same material as said substrate and thereby good adhesive strength is provided between said at least one layer portion and said substrate after sintering of said at least one layer portion and said substrate.
