Filed:

Sep 28, 1982

Appl. No.:

6/425443

Inventors:

George A. Kline - Birmingham MI

Assignee:

Eltech Systems Corporation - Chardon OH

International Classification:

C25C 326

US Classification:

204 64T

Abstract:

A low current density, fused salt electrolyte method for depositing passivating metals upon graphite. The passivating metals are applied at 50-100 milliamperes per cm. sup. 2 for 2-10 minutes followed by further deposition at 5-25 milliamperes per cm. sup. 2 in an inert fused salt electrolyte bath.

Abstract:

A process for electroplating copper from an aqueous alkaline non-cyanide bath has improved resistance to degradation. At least a portion of the plating bath is subjected to electrolysis by an insoluble anode to which the current is controlled independently from the current to the soluble copper anode in order to reduce the level of bath impurities and maintain the quality of the deposit.
