  • Patent number: 5135633
    Abstract: An anode arrangement used in electrolytic processes for steel strip galvanizing or chrome-plating has a plate-like anode of titanium with an active surface, which is connected to a generally planar carrier having a steel core and a current supply conductor comprising a sleeve element and a bushing element. The core has a passage extending through it to receive the bushing element, and, for protection against attack by the electrolytic solution, the core is loosely surrounded by an envelope of titanium foil; in the region of the bushing element, the envelope has passages, the edges of which are welded to the bushing element in a gas-tight and fluid-tight manner.
