Document Type and Number:
Japanese Patent JPH083138
Kind Code:
B2
Abstract:
Disclosed is a corrosion resistant aluminum-based alloy which is composed of a compound having a composition consisting of the general formula: AlaMbMocXdCre wherein: M is one or more metal elements selected from the group consisting of Ni, Fe, Co, Ti, V, Mn, Cu and Ta; X is Zr or a combination of Zr and Hf; and a, b, c, d and e are, in atomic percentages; 50% = a = 89%, 1% = b = 25%, 2% = c = 15%, 4% = d = 20% and 4% = e = 20%, the compound being at least 50% by volume composed of an amorphous phase. The Al-based alloy exhibits a very high corrosion resistance in severe corrosive environments, such as hydrochloric acid solution or sodium hydroxide solution, due to the formation of a highly passive protective film. Therefore, the alloy exhibits a good durability in long services under such severe corrosive environments.
