Abstract
A method of facilitating electrolytically depositing chromium onto a metal substrate from an electrolyte including an ionic form of chromium and one or more organic additives in an electrodeposition vessel by applying a current through the electrolyte from an anode to the metal substrate to deposit the chromium on the metal substrate. The method comprises providing the anode, the anode including a core comprising a valve metal, an interlayer disposed on the core and comprising one of a titanium-tantalum alloy or a titanium-palladium alloy, and a catalyst material layer disposed on the interlayer.
Claims9
A method of facilitating electrolytically depositing a metal onto a conductive substrate, the method comprising:
- depositing a metal onto a conductive substrate from an electrolyte including an ionic form of the metal and one or more organic additives in an electrodeposition vessel by applying a current through the electrolyte from an anode to the conductive substrate;
- and
- wherein the anode includes:
- a core comprising titanium,
- an interlayer disposed on the core and comprising one of a titanium-tantalum alloy comprising titanium and tantalum in a weight ratio of 30:70 to 70:30, a titanium-palladium alloy, titanium grade 7, titanium grade 7H, titanium grade 11, titanium grade 16, titanium grade 16H, titanium grade 17, or titanium grade 19, wherein the interlayer has a metal loading of about 0.2 g/m2 to about 3.5 g/m2;
- and
- a catalyst material layer disposed on the interlayer and comprising iridium and tantalum in a mass ratio of 9:1 to 2:1.
