METHOD FOR FABRICATING NANO-POWDERS USING Al-BASED AMORPHOUS ALLOY

摘要

The present invention relates to a method of manufacturing a nano powder using an aluminum-based amorphous alloy, comprising the steps of preparing an aluminum-based amorphous alloy containing 80-99 at% of Al, 0.5-10 at% of Ni and 0.5-10 at% of Y, And a step of heating the prepared aluminum-based amorphous alloy to deposit vaporized material on the substrate at a temperature ranging from room temperature to 2/3 of the melting temperature of the aluminum-based amorphous alloy, whereby the strength, abrasion resistance, And a nano powder excellent in resistance to corrosion can be produced.;
