AIR DISCHARGER FOR THERMAL SPRAYING, THERMAL SPRAYING DEVICE, AND METHOD FOR REPAIRING AN ARTICLE TO BE CORROSION-PREVENTED WITH THE USE OF THE THERMAL SPRAYING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a handy-type thermal spraying device which is lightweight and portable, does not make a base powder vaporize even when the powder overmelts, does not widely spout thermal spraying particles but precisely spout them only onto a part to be thermal-sprayed, and further does not peel a coating around the part to be thermal-sprayed due to thermal spraying heat, and to provide an air discharger for thermal spraying.;SOLUTION: The air discharger for thermal spraying which blows air supplied from an air feed section toward a thermal spraying direction from the circumferential front face of an air-discharging section 3 of a cylindrical body through an air pipe 2 comprises: a penetration port 4 for inserting a pipeline of a thermal spraying torch in a center of the air-discharging section; a plurality of air outlet holes 5 on a concentric circle in the circumferential front face of the air-discharging section; an air inlet hole 6 which is arranged in the circumferential rear face of the air-discharging section, communicates with a plurality of the air outlet holes in the air-discharging section, and engages one end of the air pipe; and an air inlet 7 in the other end of the air pipe to be connected with the air feed section.;COPYRIGHT: (C)2006,JPO&NCIPI
