Abstract

The invention discloses an anti-corrosive liquid amplitude-modulation decomposing type nickel alloy for a lithium bromide refrigerator. The anti-corrosive liquid amplitude-modulation decomposing typenickel alloy comprises the following components in percentage by weight: 0.6 to 0.9wt% of Ca (calcium), 1.5 to 2.8wt% of Ag (silver), 3.0 to 4.0wt% of Bi (bismuth), 2.0 to 2.5wt% of Pb (plumbum), 4.0to 6.0wt% of Si (silicon), 0.4 to 0.8wt% of Mn (manganese), 0.1 to 0.3wt% of Ce (cerium), 5.0 to 8.0wt% of Cu (copper), and the balance of nickel. The anti-corrosive liquid amplitude-modulation decomposing type nickel alloy has the advantages that a technical scheme different from copper alloy is provided for the anti-corrosive alloy of the lithium bromide refrigerator, and a kind of nickel alloywith excellent casting property is provided; the implementing and industrialization of the alloy can greatly promote the updating of anti-corrosive novel materials under the extreme corrosion environment of lithium bromide and commercial upgrading requirements in refrigerating industry of China.

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 ...
