ABSTRACT:
An electric arc spray metalizing apparatus includes a spray gun which delivers a metalizing coating to the substrate, and a wire feed drive mechanism which pushes wires to the spray gun through cables. The wire is pushed by a pair of drive contact rollers or devices which are connected in a tandem relationship and operatively contact each wire to individually impart driving or pushing force to the wire. The wires are directed at the spray gun to an intersection point where electrical energy creates an arc for consuming the ends of the wires at the intersection point. The wires are electrically charged by contact with a curved wire guide as the wires are bent when pushed through the wire guide. A flow stream of pressurized gas is directed onto the intersection point and the molten metal of the consumed wire ends is directed in a spray stream of molten metal particles. A pair of deflecting streams of pressurized gas influence the spray stream by deflecting it into an elliptical or elongated deposition pattern. The orientation of the spray stream and deposition pattern can be changed relative to the spray gun by rotating a deflection housing which creates the deflecting streams. The wire feed drive mechanism includes a housing for shielding the interior elements from the ambient environment, and a supply of pressurized gas is directed to the interior of the housing to prevent the entrance of airborne particles.
