Title:

DEVICE AND METHOD FOR FORMING AMORPHOUS COATING FILM

Document Type and Number:

WIPO Patent Application WO/2011/086669

Kind Code:

A1

Abstract:

A device for forming an amorphous coating film is disclosed in which a flame containing raw-material particles is jetted from a spray gun toward a base material to melt the raw-material particles by the action of the flame, and the raw-material particles and the flame are cooled with a cooling gas before reaching the base material. In the device, a cylindrical structure which separates the flame from the outside air have been disposed in the region for melting the raw-material particles which is part of the passage through which the flame from the spray gun is jetted, and a channel for the cooling gas has been formed so that the channel is integrated with the cylindrical structure. This device has advantages that it is possible to form amorphous coating films of various metals including a metal that has a high melting point and a narrow supercooled-state temperature range and that the device is compact and generates little oxide.
