A METHOD OF ELECTRODEPOSITING ON A CONTINUOUSLY TRAVELING METAL TRIP AN ALUMINIUM-CONTAINING COATING FROM A FUSED SALT ELECTROLYTE BATH CONTAINING ALUMINUM HALIDE COMPRISING PASSING THE STRIP THROUGH THE BATH IN ELECTRICAL, CIRCUIT WITH THE ELECTROLYTE WITHDRAWING THE STRIP FROM THE BATH WITH A COATING OF ELECTROLYTE ON THE STRIP THE WITHDRAWN STRIP BEING SUFFICIENTLY HOT TO VAPORIZE ALL OF THE ALUMINUM HALIDE CONTENT OF THE COATING OF ELCTROLYTE, PASSING THE STRIP THROUGH A HEATING ZONE REMOTE FROM THE ELECTROLYTE BATH TO HEAT THE STRIP TO A TEMPERATURE ABOVE THE VAPORIZATION TEMPERATURE OF THE ALUMINUM HALIDE ON THE STRIP TO VAPORIZE ALUMINUM HALIDE FROM THE STRIP, REMOVING THE HEATING ZONE VAPORS CONTAINING VAPORIZED ALUMINUM HALIDE, COOLING THE REMOVED VAPORS TO BELOW THE CONDENSATION TEMPERATURE OF THE ALUMINUM HALIDE IN A COOLING ZONE TO RECONDENGE THE ALUMINUM HALIDE FROM THE COOLED VAPORS, AND REMOVING THE RECONDENSED ALUMINUM HALIDE FROM THE COOLING ZONE.
