Abstract

Nakayama Steel Works LTD. has succeeded in attaining the cooling rate (105 -106 K/s) necessary for amorphous layering technique by using the innovative idea of immediately cooling the spraying flame. Amorphous alloy (Fe70Cr10P13C7) formed by the new technique displays a corrosion resistance more than 500 times higher than the one of SUS316L in aqua-regia immersion test, while the similarly formed amorphous magnetic alloy film (Fe81B13Si4C2) indicates high magnetism of 15.4 kGauss in magnetic flux density.
