International Classification:

C25D 304
C25D 306
C25D 2118

US Classification:

205283

Abstract:

A sulfate scavenger for chromium-plating baths consists of barium chromate or dichromate or mixtures of the two, added either directly to the bath or as part of a replenishment mixture with chromic acid.

Sep 17, 1986

Appl. No.:

6/908434

Inventors:

Kenneth R. Newby - Berkeley Heights NJ

Assignee:

M&T Chemicals Inc. - Woodbridge NJ

International Classification:

C25D 534
C25D 304

US Classification:

204 29

Abstract:

What is described herein is a method of electroplating an adherent chromium deposit on a chromium substrate. The process is characterized by chemically oxidizing the chromium substrate before starting the electrodeposition of chromium thereon. A suitable chemical oxidizing agent is hydrogen ion, which can be furnished by a dilute acid solution. The invention is applicable to any chromium electroplating bath, including high energy efficient chromium baths, such as HEEF-40 baths, which are presently in commercial use.

International Classification:

H01M 400
H01M 800

US Classification:

429 18

Abstract:

An electrochemical cell construction features a novel co-extruded plastic electrode in an interleaved construction with a novel integral separator-spacer. Also featured is a leak and impact resistant construction for preventing the spill of corrosive materials in the event of rupture.

Inventors:

Kenneth Newby - Berkeley Heights NJ

Assignee:

M&T Chemicals Inc. - Woodbridge NJ

International Classification:

C25D 310

US Classification:

204 51

Abstract:

A method of treating a chromium electroplating bath which contains an alkyl sulfonic acid to prevent heavy scale build-up of lead dioxide on lead or lead alloy anodes used therein is described herein. The method involves applying a voltage across the electrodes in said bath which is greater than the normal operating voltage during electrodeposition of chromium.

Appl. No.:

8/268476

Inventors:

Kenneth R. Newby - Berkeley Heights NJ

Assignee:

Elf Atochem N. A., Inc. - Philadelphia PA

International Classification:

C25D 310

US Classification:

205283

Abstract:

The present invention provides an improved method for electroplating chromium, using lead anodes, while achieving the advantages of using methanesulfonic acid without suffering the excessive anode-corrosion characteristics associated with that acid. Accordingly, chromium is electrodeposited from a bath containing chromic acid, sulfate ion and an alkylpolysulfonic acid containing from one to about three carbon atoms. The preferred alkylpolysulfonic acid is methanedisulfonic acid.

Assignee:

Elf Atochem North America, Inc. - Philadelphia PA

International Classification:

C25D 310

US Classification:

205284

Abstract:

The present invention provides a process for electroplating chromium using lead anodes while achieving the advantages of using methanesolfonic acid without suffering the excessive anode-corrosion characteristics associated with that acid. Accordingly, chromium is electrodeposited from a bath containing chromic acid, sulfate and an alkylpolysulfonic acid containing from one to about three carbon atoms. The invention also provides a plating process for chromium electrodeposition, a plating bath for use in the inventive process, and a replenishment composition for existing plating baths.
