摘要 |
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 containing metal particles is ejected toward a base material from a nozzle, such that the material particles are melted with the flame. Thereafter, the melted material particles and flame are cooled before they reach the base material. For this cooling process, a gas is externally ejected toward the flame, such that the gas can gradually approach the central line of the flame. Preferably, the particle size of the material particles in the flame is within a range of 10 to 100 mum.
