摘要:
The present invention provides an improved anode formulation and an improved method of manufacture. More specifically, the invention provides a tri-layer anode having an improved service life when used, for example, for steel strip electrogalvinizing. In one embodiment of the invention, the anode is comprised of a titanium substrate which is roughened and heat treated and subsequently coated with a first coating of iridium oxide/tantalum oxide. After the anode is heat treated, it is next coated, preferably by an electrodeposition process with a second coating of platinum. Finally, the anode is coated with a third coating of iridium oxide/tantalum oxide and subsequently heat treated.
