Definitions
- This invention relates to plating aluminum; and it comprises a method of electrically plating articles of aluminum and aluminum alloys with other metals wherein such an article is electro- 5 lytically treated until an oxidized film develops,
- an expedient which consists in first producing an oxidized coating of different nature and-afterwards simultaneously partially removing it and depositing a film coating of another metal on, the aluminum as the coating is partially removed.
- the metal of the surface is a part of the surface of the oxidized coating of different nature and-afterwards simultaneously partially removing it and depositing a film coating of another metal on, the aluminum as the coating is partially removed. The metal of the surface.
- the coating can be,par-,
- Thefilm coati'ng deposited from an alkaline bath although very thin, adheres well to the underlying layer.
- the film coating can be afterwards plated in the regular way in any convenient bath with nomore difllculty than an article of the same kind made of copper, or of brass, as the case may be.
- the metal for the film coating is best copper or brass, although cadmium, silver or gold can be used if desired.
- the metal for the main coating may be any of the usual metals deposited by electroplating that is, copper, brass, gold, silver, nickel, chromium, .cadmium, etc.
- the present process is applicable to the coating of aluminum with any metal which may be desired for decoration or protection.
- the first and second step of the process may be conducted in a single bath
- alternating or direct current may be used; the article being made an anode in the latter event.
- the article is made a cathode and voltage may beapplied as is necessary, that usually used being ordinarily over 5 volts. After formation of the primary metallic or film coating, the main coating is applied.
- an article of aluminum is made an anode for 15 to 30 minutes in a chromic acid bath of the kind described. This converts the usual 110 .the deposition of brass.
- the article is removed from the chromic acid bath, washed and made a cathode at about 6 volts in an alkaline bath adapted for After two to three minutes passage of the current enough metal is deposited on the aluminum in adherent relationship therewith to serve as a basis for subsequent plating. After washing, the article may be directly plated with any desirable metal among those named hereinbefore.
- an aluminum article is placed in a bath containing double copper-alkali cyanids and zincalkali cyanids, together with a counter electrode of sheet iron and an alternating current is imposed.
- This current may be at 30 to 40 volts and the current density may be 800 amperes per square meter.
- direct current is substituted, making the aluminum a cathode without changing the treating bath.
- the brassed article may be removed from the bath and plated with gold, copper, brass, tin, silver, nickel, chromium, cadmium, etc., in any suitable bath.
- Plated aluminum articles produced under the present invention may be buffed, polished and otherwise finished in the usual ways.
