METHOD FOR PRODUCTION OF INSOLUBLE ANODE ON TITANIUM BASE Russian patent published in 2012 - IPC C23F13/00 H01R4/66 C25B11/10 

FIELD: metallurgy.

SUBSTANCE: titanium base of an anode is arranged from a thin-walled titanium pipe with a titanium wire wound onto it and forming an outer relief layer, at the same time a groove is applied onto a pipe with threading, with depth of 0.1-0.3 mm, with a pitch of 1.5-3 of titanium wire diametre, where spot welded pipes are fixed by winding along a threaded groove and fixed, with further filling of the space between turns of the wire with a layer of manganese dioxide layer. Additionally the protective layer made of manganese dioxide includes a highly dispersed powder of titanium carbide with specific surface of at least 10 m²/g in the amount of 3-5%.

EFFECT: increased resource of anode operation is the technical result of the invention, the warranty service life of the entire system of electrochemical protection makes more than 50 years.
