Abstract
Official abstract text for this publication.
A corrosion-resistant nickel alloy is provided. The alloy includes the following components in percentage by mass: 4.68-5.35% of B, 5.69-6.41% of W, 27.68-28.39% of Cr, 12.65-13.42% of Al, and the balance of Ni and inevitable impurities. The corrosion-resistant nickel alloy is a Ni—W—B ternary alloy with main components of Ni, W and B, wherein the three elements have strong high-temperature corrosion resistance at a temperature of about 600° C., and have the potential of solid solution hardening and precipitate formation because all belong to solid solution forming elements, so that a creep strength of a nickel alloy matrix is improved. Meanwhile, Al and Cr are further added in the alloy formula, so that Al 2 O 3 and Cr 2 O 3 oxide layers can be formed, which play a role as a physical diffusion barrier against chlorine gas and other corrosive gases.
