Abstract

Nakayama Steel Works LTD. has succeeded in attainingthe cooling rate (105 -106 K/s) necessary for amorphouslayering technique by using the innovative idea ofimmediately cooling the spraying flame. Amorphous alloy(Fe70Cr10P13C7) formed by the new technique displays acorrosion resistance more than 500 times higher than the oneof SUS316L in aqua-regia immersion test, while the similarlyformed amorphous magnetic alloy film (Fe81B13Si4C2)indicates high magnetism of 15.4 kGauss in magnetic fluxdensity.
