ABSTRACT:
A method of preparing electrodes is now described, which electrodes have enhanced adhesion of subsequently applied coatings combined with excellent coating service life. In the method, a substrate metal, such as a valve metal as represented by titanium, is provided with a highly desirable rough surface characteristic for subsequent coating application. This can be achieved by various operations including etching to ensure a roughened surface morphology. In subsequent operations, a barrier layer is provided on the surface of enhanced morphology. This may be achieved by operations including heating, as well as including thermal decomposition of a layer precursor. Subsequent coatings provide enhanced lifetime even in the most rugged commercial environments.
