    摘要: A metal surface, useful as an electrode in an electrolytic cell, is now described having enhanced adhesion of subsequently applied coatings combined with excellent coating service life. The substrate metal of the electrode, 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 and melt spray application of metal or ceramic oxide to ensure a roughened surface morphology. Usually 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.
