Abstract
Apparatus for electrodepositing aluminum in which an electroplating trough, which contains aprotic oxygen-free and water-free organo-aluminum electrolyte, is closed off in an airtight manner and is accessible only via a lock chamber disposed thereabove and which uses, for inserting and removing the work pieces, a detachable coupling rod carrying a frame with the articles to be electroplated permitting a strongly adhering aluminum layer to be deposited onto work pieces of any design desired with the exclusion of air.
Claims12
Apparatus for electrodepositing aluminum from an aprotic, oxygen-free and water-free organo-aluminum electrolyte comprising:
- a. an electroplating tank containing the electrolyte having means for closing it off in an airtight manner;
- b. means to supply an inert gas to said tank;
- c. a contact making and holding device disposed within the electroplating tank and adapted for horizontal or rotatable movement of a work piece holder;
- d. a lock chamber disposed above the electroplating tank having a closable lock opening for inserting and removing work pieces to be electroplated;
- e. a closable flap coupling said tank and said chamber;
- f. an inert gas flooding system for flooding said chamber;
- g. a coupling rod arranged in the lock chamber and supported for vertical motion into and out of said electroplating tank for receiving a work piece holder, transferring said holder to the contact making and holding device and reinserting said work piece holder.
