Abstract

The invention discloses novel low-temperature environment-friendly friction-resistant B-and-Ge-containing aluminum alloy for hot dipping. The aluminum alloy comprises, by weight percentage, 0.2-0.4% of K, 0.5-0.8% of V, 0.4-0.5% of Ge, 1.0-2.0% of Sr, 0.3-0.5% of Sc, 0.1-0.2% of Ce, 0.1-0.2% of B and the balance aluminum. By means of the aluminum alloy, the current situation that at present, the field of hot dipping aluminum alloy of China is lag in technology is changed; and by means of technological innovation and optimization design, the development bottleneck of the production technology and device for hot dipping aluminum-steel plates applied to high-end fields of China is broken through. In the near future, the material can be definitely applied to more fields more widely.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to an aluminum alloy. Background technique [0002] Corrosion of steel refers to a damage phenomenon caused by chemical or electrochemical action when steel is in contact with the surrounding medium. Corrosion of steel has brought a lot of inconvenience to production and life, resulting in huge economic losses. The direct economic loss caused by steel corrosion in the world is about 700 billion U.S. dollars every year, which is 6 times the sum of losses caused by natural disasters such as earthquakes, floods, and typhoons. The loss caused by steel corrosion in my country accounts for about 4% of the gross national product, and the amount of steel scrapped due to corrosion accounts for about 25%-30% of the annual output of steel. [0003] Hot-dip galvanizing is the reaction of molten zinc with an iron substrate to produce an alloy layer, thereby combining the substrate and the coati...
