Abstract

The invention discloses a hot-dipped galvanized aluminum alloy containing Mg and Ca for a fishery steel wire under the marine environment. The hot-dipped galvanized aluminum alloy comprises the ingredients of, in percentage by weight, 0.3-0.5% of Ca, 2.0-4.0% of Mg, 0.3-0.5% of Ti, 1.0-3.0% of Sn, 30.0-42.0% of Al, 0.5-0.8% of Cr and the balance zinc. The hot-dipped galvanized aluminum alloy for the marine fishery steel wire can be used at the temperature of 420-480 DEG C, and better corrosion resistance is achieved compared with a traditional hot-dipped coating. The hot-dipped galvanized aluminum alloy has great significance to prolonging of the service life of the marine fishery steel wire.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a zinc alloy. Background technique [0002] The ocean covers about 71% of the earth's surface, and the marine industry has become an important pillar of the world's economic development. The salt concentration in seawater is high, oxygen-rich, and there are a large number of marine microorganisms and macrobiotics. Coupled with the impact of waves and sunlight, the marine corrosion environment is relatively harsh. Corrosion in the marine environment has become the most important factor affecting the safety, service life and reliability of facilities, and has attracted great attention from governments and industries around the world. [0003] The steel wire will corrode in seawater and shorten the service life of the steel wire. For wire ropes used in marine fishing and other offshore operations, improving their corrosion resistance is the key to extending their service life. Hot...
