Title (EN) IMPROVEMENTS RELATING TO METAL SPRAYING APPARATUS
(FR) APPAREILLAGE DE PULVERISATION DE METAL
Abstract: front page image
(EN)A metal spraying apparatus comprises a gun having convergent guide passages (36, 38) through which metallic wires are fed. An electrical potential is applied across the wires, by conductor elements (54), to cause arcing between the wires were they emerge from the guide passages, which melts the wires. A stream of compressed air causes molten metal droplets to be carried from the arcing zone towards the surface to which a metallic coating is to be applied. The apparatus also comprises a supplying device, to supply electricity and air under pressure to the gun. The conductor elements extend within conduits (18) through which air is fed to the gun, and the gun comprises a valve (9) for cutting off the flow of air through the gun. The supplying device comprises control means (82) which is responsive to such cut off, to cut off the supply of electricity to the gun.
(FR)Un appareillage de pulverisation de metal comprend un canon possedant des passages de guidage convergents (36, 38) au travers desquels des fils metalliques sont alimentes. Un potentiel electrique est applique sur les fils par des elements conducteurs (54) afin de provoquer un arc entre les fils au moment ou ils emergent des passages de guidage, ce qui les fait fondre. Un jet d"air comprime force des gouttelettes de metal fondu a etre arrachees de la zone de l"arc pour etre transportees vers la surface sur laquelle un revetement metallique doit etre applique. L"appareillage comprend egalement un dispositif d"alimentation, pour fournir de l"electricite et de l"air au canon et celui-ci comprend une soupape (9) pour couper le jet de gaz au travers du canon. Ce dispositif d"alimentation comprend des moyens de commande (82) qui sont sensibles a un tel arret afin de couper la fourniture d"electricite au canon.
