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.
