    Abstract: For thermocompression sealing at least one of the materials to be joined is provided with an oxide skin before or during the sealing operation. The oxide skin can be formed, for example by firing in air. It has been found that the method is particularly advantageous for seals between a CrNi-alloy and, for example a second element which consists of aluminium, for example the seal between an Al entrance window and a CrNi-steel envelope of an X-ray intensifier tube. Notably by addition of an intermediate material, in particular aluminium, seals can thus be realized between many materials.
