Abstract

To prevent transport of deleterious oxygen and moisture to liquid electrolyte in an aluminum electroplating vessel, workpieces move towards the vessel through an antechamber containing inert gas under pressure and comprising a plenum chamber opening downwardly into a lock chamber containing aprotic liquid. They move down into the liquid, then up out of it, into and through an inverted-U-shaped passageway containing higher pressure inert gas and which communicates with the lock chamber below the surface of the liquid therein and communicates with the electrolysis vessel above the surface of the electrolyte. At each connection between parts, where atmospheric oxygen might move towards the electrolyte, there are double mechanical seals defining a substantially annular chamber filled with aprotic liquid that forms a gas barrier, and such liquid is, where possible, shielded by inert gas.
