Example Embodiment

[0017] In the following, the present invention will be further described in conjunction with the embodiments.

[0018] The formulations of the examples are shown in Table 1.

[0019] According to Table 1, the metal raw materials are weighed according to the proportion, and are sequentially added to the smelting furnace to be smelted together. After refining and pouring, the billet is formed, and then it is drawn into a wire through a wire drawing machine for many times. The wire diameter is 3mm.

Abstract

The invention discloses a rare earth aluminum alloy wire for thermal spraying, which belongs to the technical field of thermal spraying. The wire contains aluminum, zinc, magnesium and the like, and also contains two or more than two rare earth metal elements, and the total weight of rare earth metal elements accounts for 0.51-5.00% of the total weight of the wire. The invention has the advantages that the processing and manufacturing process is convenient and the product coat cost is moderate; and the metal thermal spraying coating made from the wire has good adhering capability, good physical and mechanical property, good corrosion-resistant property, and moderate construction cost, and is favorable for popularization and application.

Description

technical field [0001] The invention relates to a metal wire material for thermal spraying in the field of surface engineering corrosion protection, in particular to a rare earth aluminum alloy wire material for thermal spraying, and belongs to the technical field of thermal spraying. Background technique [0002] Metal corrosion has become the greatest hazard to large steel structures, seriously affecting their safety and life. According to the statistics of the U.S. Highway Administration in 1998, there were 279,543 interstate and national bridges in its territory, and 68,466 bridges needed to be repaired due to corrosion, with a corrosion rate of 24.5%. The 7th corrosion loss survey released by the United States in 2002 showed that the annual direct corrosion loss in the United States was 276 billion US dollars from 1999 to 2001, accounting for about 3.1% of GDP; in my country it reached 4%, and the indirect corrosion caused by corrosion The loss is more difficult to estim...
