Amorphous alloys resistant against hot corrosion

摘要

An amorphous alloy which is resistant to hot corrosion in sulfidizing and oxidizing atmospheres at high temperatures, consisting of Cr and at least one element selected from refractory metals of Nb and Ta, a portion of the set forth refractory metals being allowed to be substituted with at least one element selected from Ti, Zr, Fe, Co, Ni and Cu. The addition of Si further improves the alloy's oxidation resistance.
