<p>The present invention provides a method and an apparatus for forming, by spraying, a commonly known amorphous coating film, which is not limited to a metallic glass or the like. According to this invention, a flame F containing metal particles is ejected toward a base material M from a nozzle 5, such that the material particles are melted with the flame F. Thereafter, the melted material particles and flame F are cooled before they reach the base material M. For this cooling process, a gas H is externally ejected toward the flame F, such that the gas can gradually approach the central line of the flame F. Preferably, the particle size of the material particles in the flame F is within a range of 10 to 100pm.</p> |
