ABSTRACT:
A cathode-ray tube comprises an evacuated envelope which includes a faceplate panel joined to a funnel. A steel shrinkfit implosion protection band having a metallic protective coating thereon is fitted around the periphery of the panel to apply a compressive force thereto. The corrosion resistance of the band is enhanced by providing a metallic barrier layer between the steel band and the metallic protective coating.
A method of forming the enhanced corrosion resistant band also is disclosed.
