<P>PROBLEM TO BE SOLVED: To provide a method for easily forming an amorphous film even on a large area part of a base metal with a simple operation. <P>SOLUTION: This forming method includes thermal-spraying a metal as a material onto the base metal so that the cooling rate can be 100,000°C/second or higher. The method controls, for instance, a maximum temperature of a thermal-spraying flame to 2,000 to 3,000°C and the temperature of a base metal surface to 500°C or lower. The metal used for the material preferably prepared by mixing metallic powders of Mg and Zn such that a weight ratio of Mg can be 2 to 5%. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
