The immersion plating aluminum alloy coating materials are low in cost and high in property.

Description

technical field [0001] The invention relates to an aluminum alloy coating material, in particular to a low-cost and high-performance immersion aluminum alloy coating material. Background technique [0002] The loss caused by corrosion to steel is extremely serious. According to incomplete statistics, 1 / 3 of the world's annual steel production is lost due to corrosion, and the annual loss in China alone is hundreds of millions of yuan. At the same time, corrosion can also cause casualties. . At present, there are two effective methods to prevent and control the corrosion of steel materials: one is metal alloying; the other is metal coating anticorrosion method. The production process of metal alloying is complex and expensive, so its popularity is limited. Hot-dip galvanizing is recognized as one of the most effective and direct methods of protecting steel in the anti-corrosion method of metal coating. [0003] Focusing on adding a variety of alloying elements to improve t...
