ABSTRACT:
A thermal spraying device with a first blowing mechanism for lengthening a droplet formed near the tips of thermal spraying materials by arc, and a second blowing mechanism for a blowing a tip portion of the lengthened droplet to atomize it into droplets and to scatter atomized droplets towards a face to be thermally sprayed. The first blowing mechanism lengthens the droplet so that the second blowing mechanism propels air to the tip portion of the lengthened droplet that is separated from a location where the tips of thermal spraying materials are adjacent and the arc is generated. Arcing between the tips of the thermal spraying materials continues stably, and satisfactory thermal spraying is possible.
