Rare-earth modification anode type zinc-aluminum alloy wire material for thermal spraying

The invention relates to a rare-earth modification anode type zinc-aluminum alloy wire material for thermal spraying which belongs to the technical field of metal alloys and thermal spraying. The wire material comprises the following components: 3-8% of Zn, 0.5-1.5% of Mg, 0.1-0.5% of Re, 0.05-0.2% of Ti, 0.01-0.17% of M, impurities of which the total amount is less than 0.5%, and the balance of Al, wherein Re is a rare-earth material, and M is any one or the combination of In, Sn and Ga. The wire material combines respective advantages of zinc and aluminum, an alloy coating is modified by adding rare-earth elements, the electrode potential of the coating is reduced by adding elements such as indium, tin, gallium and the like, and the current efficiency of the coating is improved, so that a compact coating with a good cathode protection function and a certain self-sealing function is obtained; and meanwhile the occurrence of corrosive pitting is avoided, therefore steel is effectively prevented from corrosion
