The mixture was mixed with 0.5 g of low melting point glass (softening point: 360°C) consisting of 22.3%-AtOl, 2%-G+1022-3%, and heated to melt the glass. As a result, the autoclave-treated powder wetted well with glass and did not fall off even when cut, whereas the untreated powder fell off when cut and had very poor wettability with glass.

However, in amorphous alloys containing Ni as a main component, NiO is often formed, but these differ depending on the manufacturing conditions. Furthermore, in the case of amorphous alloys containing both Co and Fe*Co and Ni or Fe and Nif, CoFe2O4 and CoNi204. FaN
Oxides such as i204 are formed. It has been found that oxidation resistance, corrosion resistance, and playability with inorganic materials are significantly improved regardless of which of the above crystalline oxides is formed.

More preferably, the thickness is 0.1 to 1 μm. This is because when the thickness is less than 0.05 μm, the growth of crystalline oxide is small and the wettability with inorganic substances is not improved much. On the other hand, when the thickness exceeds 5 μm, the proportion of crystalline material This is because the characteristics of the amorphous alloy deteriorate as the amorphous alloy increases.
