Abstract

The invention discloses a corrosion-resistant liquid-state amplitude-modulated decomposition type nickel alloy for a ship power system condenser. The corrosion-resistant liquid-state amplitude-modulated decomposition type nickel alloy consists of the following components in percentage by weight: 1.2-1.8wt% of In, 2.0-3.5wt% of Ag, 2.0-3.0wt% of Bi, 1.0-1.5wt% of Pb, 3.0-5.0wt% of Fe, 1.5-1.8wt% ofSb, 0.2-0.4wt% of Sm, 4.0-6.0wt% of Al and the balance of nickel. The material provides a technical scheme different from the copper alloy for the corrosion-resistant liquid-state amplitude-modulateddecomposition type nickel alloy for the ship power system condenser. The alloy can be implemented and industrialized to greatly promote updating needs and commercial upgrading needs of the novel corrosion resistant material, under an extremely corrosion environment, in the national ship industry.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a nickel alloy. Background technique [0002] Nickel is a silvery-white ferromagnetic metal that is the main constituent of many magnetic materials. There are many types of nickel alloys, which can be divided into: 1:) Nickel-based superalloys according to different application goals. It has high strength, oxidation resistance and gas corrosion resistance at high temperature of 650-1000 ° C. It is the most widely used and highest high temperature strength alloy among superalloys. It is used to manufacture aero-engine blades and high-temperature components on rocket engines, nuclear reactors, and energy conversion equipment. 2:) Nickel-based corrosion-resistant alloys. It has good comprehensive performance, can resist various acid corrosion and stress corrosion, and is used to manufacture various corrosion-resistant parts. 3:) Nickel-based wear-resistant alloy. In addition to ...
