Embodiment 1
[0020] In the thermal spraying wire in this embodiment, the core material is Al-5Mg alloy, the outer skin is Zn-0.8Al-0.35Re alloy, and the composition of the composite spraying wire is Zn-14Al-0.7Mg-0.3Re. Table 1 lists the relevant data of sprayed wire.
[0021] Table 1
[0022] Spray wire diameter / mm Al-5Mg diameter / mm Zn-0.8Al-0.35Re thickness / mm 1.6 0.88 0.36 2.0 1.1 0.45 3.0 1.65 0.675 4.0 2.2 0.9
[0023] The specific preparation method is as follows: the Zn-0.8Al-0.35Re alloy strips with a thickness of 0.36, 0.45, 0.675, and 0.9mm are rolled into a U shape by a rolling mill, and the U-shaped strips are respectively added with a diameter of 0.88mm, 1.1mm, 1.65mm, 2.2mm Al-5Mg alloy wire, then rolled into O shape by rolling mill, and finally made into Zn-14Al-0.7Mg- 0.3Re sprayed wire.

Description
technical field [0001] The invention relates to a novel thermal spraying wire material and a preparation method thereof. Background technique [0002] Thermal spraying of Zn, Al and their alloy coatings has always been one of the important technologies for surface corrosion protection of steel structures. In order to improve the corrosion protection ability of the coating on the steel substrate and ensure that the performance of the equipment will not be affected by surface corrosion failure during service, extensive research has been carried out on the spraying equipment, spraying process and spraying materials. Among them, arc spraying Zn-15Al solid wire to prepare binary alloy anti-corrosion coating is one of the most representative technologies. However, the corrosion resistance of Zn-15Al alloy coatings is weakened and the service life is significantly reduced under harsh conditions such as ocean, high temperature, high humidity, and high salt spray. For this reason, ...
