Title:
COATINGS FOR THE INHIBITION OF UNDESIRABLE OXIDATION IN AN ELECTROCHEMICAL CELL
Document Type and Number:
WIPO Patent Application WO2004038071
Kind Code:
A3
Abstract:
A process for electroplating of metal utilizing a valve metal electrode substrate containing multiple coating layers is disclosed. A top coating layer of a valve metal oxide is applied over a first coating layer of an electrochemically active coating. The electrode may find use in an electroplating system containing organic substituents in which the consumption of the organic substituent is significantly decreased or in systems where it is desirable to suppress the oxidation of a species in an electrochemical cell.
