Abstract

A composite anode for use in an impressed current cathodic protection system for control of corrosion and which is practically nonconsumable, capable of handling large current densities, and mechanically strong comprises an electric current discharging surface 12 made of platinum, rhodium, or an alloy of platinum group metals containing at least 50% of platinum or rhodium, or at least 50% of platinum and rhodium together and which is bonded, in metal-to-metal electrical contact, to an underbase of titanium 11 or an alloy containing at least 90% of titanium. The platinum group alloys may contain up to about 10% of other elements which do not affect the corrosion <PICT:0944715/C3/1> <PICT:0944715/C3/2> resistance of the anode. The anode preferably has an inner core of metal 13, Fig. 4, e.g. copper, silver, or aluminium, which has good electrical conductivity and which is completely sheathed by titanium metal. The platinum, which can be provided with a platinized surface, can be attached to the titanium e.g. by plating, spot-welding, spraying, but is advantageously applied by vacuum sublimation or cathodic sputtering methods. Suitable platinum metal alloys can contain 50%, 10%, 5% and 10% respectively of palladium, rhodium, ruthenium, and iridium, pure or commercially pure titanium, or alloys of titanium containing at least 90% of titanium being suitable for the underbase 11. Commercially available rhodium can be satisfactorily applied to the titanium underbase by electroplating. The platinum current discharging surface can be discontinuously dispersed on, without entirely surrounding, the titanium base 11 and the anode can be in the form of a strip, a dished disc, or a spiral for encircling a buried pipe. Reference has been directed by the Comptroller to Specification 877,901.
