THE METHOD OF PLATING METAL WIRE OF CONTINUOUS LENGTH WHICH COMPRISES CONTINUOUSLY MOVING THE WIRE THEREALONG FROM A SOURCE OF SUPPLY THROUGH A PLURALITY OF CHAMBERS INCLUDING A GASEOUS METAL PLATING CHAMBER, HEATING SAID WIRE AS THE SAME IS CONTINUOUSLY MOVED ALONG TO A TEMPERATURE SUFFICIENT TO DECOMPOSE A HEAT-DECOMPOSABLE GASEOUS METAL COMPOUND BROUGHT IN CONTACT THEREWITH, SAID MOVING HOT WIRE BEING MAINTAINED IN A NON-OXIDIZING ATMOSPHERE, MOVING SAID HEATED WIRE INTO SAID PLATING CHAMBER AND SUBJECTING THE SAME TO A CONTINUOUSLY MOVING GASEOUS MASS OF AT LEAST A PORTION OF WHICH COMPRISES A HEAT-DECOMPOSABLE GASEOUS METAL COMPOUND, SAID WIRE BEING HEATED TO A TEMPERATURE SUFFICIENT TO CAUSE DECOMPOSITION OF SAID HEAT-DECOMPOSABLE GASEOUS METAL COMPOUND WHICH IS CIRCULATED IN CONTACT THEREWITH AND DEPOSITION OF THE METAL CONSTITUENT THEREOF ON THE SURFACE OF THE WIRE AS THE SAME IS CONTINUOUSLY MOVED THEREALONG, AND MAINTAINING A DIFFERENTIAL IN GASEOUS PRESSURES BETWEEN SAID PLATING CHAMBER AND PRECEDING AND SUCCEEDING CHAMBERS, SAID PRESSURES WITHIN THE CHAMBERS ADJACENT THE PLATING CHAMBER BEING SLIGHTLY HIGHER THAN THAT WITHIN SAID PLATING CHAMBER TO PREVENT LEAKAGE OF SAID GASEOUS METAL COMPOUND FROM SAID PLATING CHAMBER.
