摘要： Amorphous alloys having an extremely high corrosion resistance comprise Cr and at least one element selected from Ta and Nb, as essential components, and are spontaneously passive owing to the formation of stable protective films, even in very corrosive environments such as poorly oxidizing concentrated hydrochloric acid. The amorphous alloy may further include one or more elements appropriately selected from other alloying elements of Al, Ti, Zr, Fe, Co, Ni, Cu, Mo and W. The amorphous alloys have advantageous properties, such as very high corrosion resistance, high corrosion resistance at elevated temperatures and high wear resistance, and, therefore are useful in chemical plants or other industrial and domestic applications.

摘要： This invention relates to a catalyst for cleaning exhaust gas, which is prepared by dipping in hydrofluoric acid an amorphous alloy composed of 20 to 80 atom % of one or more elements selected from the group consisting of Nb, Ta, Ti and Zr (the sum of Nb and Ta being up to 70 atom %), 0.5 to 20 atom % of one or more elements selected from the group consisting of Ru, Pd, Rh, Pt and Ir, and the balance of one or two of Ni and Co. This catalyst can clean at a low temperature an exhaust gas containing NO or CO discharged from apparatuses or engines wherein various organic substances are burnt.
