  • Patent number: 5718777
    Abstract: An amorphous alloy which is resistant to hot corrosion in sulfidizing and oxidizing atmospheres at high temperatures, consisting of at least one element selected from the group of Al and Cr and at least one element selected from the refractory metals Mo, W, Nb, and Ta, a portion of the set forth refractory metals being allowed to be substituted with at least one element selected from Fe, Co, Ni and Cu. The addition of Si further improves the alloy's oxidation resistance.
    Type: Grant
    Filed: July 23, 1996
    Date of Patent: February 17, 1998
    Assignees: Koji Hashimoto, YKK Corporation
    Inventors: Koji Hashimoto, Hiroki Habazaki, Stanislaw Mrowec, Marek Danielewski
