Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a zinc alloy. Background technique [0002] The loss caused by the corrosion of metal materials to the national economy is astonishing. According to statistics, the weight of metal products that fail due to corrosion every year in the world is equivalent to about one-third of the annual output of metals. In the industrially developed Britain and the United States, the economic losses caused by corrosion account for about 4% of the total output value of the national economy. Due to the unfavorable implementation of protective measures for steel in my country, the loss caused by corrosion accounts for a larger proportion. The implementation of the hot-dip galvanizing process is one of the most basic and extensive methods of steel corrosion protection in the world. A layer of galvanized layer is formed on the surface of steel products by hot-dip galvanizing process, and the very d...
