ABSTRACT:
The adhesion of conductive layers to ceramic substrates in the application of such layers by low-energy techniques is improved by interposing between the high-conductivity metal layer and the substrate a layer of a refractory metal which is preferably also applied by low-energy vaporization. The metal layers can be provided in succession by reversing the polarity of electrodes composed of the metals of these layers which strike an arc vaporizing the metal to be deposited.
