Background
Metal corrosion is a phenomenon in which a chemical reaction or an electrochemical reaction occurs between a metal and a surrounding medium environment, thereby causing deterioration or destruction of the metal material. The basic methods currently used for metal corrosion protection are the following: (1) the composition of metal components is changed, and the corrosion resistance of the metal is improved; (2) treating the metal surface, such as brushing corrosion-resistant paint and the like; (3) with appropriate electrochemical protection. The electrochemical protection is mostly implemented by a sacrificial anode protection method. The sacrificial anode protection method is to connect the metal to be protected with the active metal with more negative potential to form a loop, and then to continuously dissolve the more active metal with more negative potential to provide a current source for cathodic protection. For example, in the protection of tanks, subsea pipelines, and ocean going vessel hulls. Commonly used sacrificial anode materials mainly include three types: zinc alloys, magnesium alloys and aluminum alloys. Compared with zinc-magnesium alloy, aluminum alloy has a relatively small specific gravity, and has a series of advantages of high current efficiency, large theoretical capacitance, rich raw material sources and the like, and is the most important sacrificial anode material. The conventional sacrificial anode is of a solid structure, only the structure surface of the solid structure is in contact with a medium, and when the sacrificial anode is used, the contact area with the medium is small, so that the working efficiency of the sacrificial anode is low.

Preferably, the preparation process is as follows:
(1) manufacturing an aluminum alloy rod; (2) homogenizing the aluminum bar; (3) detecting components; (4) drawing a pressing strip; (5) shredding; (6) compression molding; (7) heating and homogenizing.
Preferably, the composition of the aluminum wire is as follows: 3.0-6.0% of Zn, 0.01-0.05% of In, less than 0.05% of Si, less than 0.03% of Fe, less than 0.02% of Cu and the balance of Al.
Preferably, in the step (1), the materials are mixed according to the component requirements in the prepared materials, the smelting temperature is controlled to be 745-755 ℃, and liquid is subjected to slag skimming and degassing to obtain molten liquid; refining the molten liquid, wherein the temperature is controlled to be 740 and 745 ℃ in the refining process, and the standing time is 15-20min, so as to obtain aluminum liquid; casting into aluminum bars after double-stage filtration.
Preferably, in the step (2), the homogenizing temperature is 510 +/-10 ℃, the heat preservation time is 6-7 hours, and after air cooling is carried out for 30-40 min, water is used for cooling to the room temperature.
Preferably, the step (4) is: heating the aluminum bar with qualified component detection to 500-520 ℃, rolling into an aluminum alloy strip with a diameter of 4-6 mm, and drawing the aluminum alloy strip into an aluminum alloy wire with a diameter of 0.15-0.25 mm through a wire drawing device.
Preferably, the step (5) is: and (4) cutting the aluminum alloy wire prepared in the step (4) into short aluminum wires with the length of 5-15 mm through a spring machine.
Preferably, the step (6) is: heating the short aluminum wire prepared in the step (5) to 380-410 ℃, then randomly placing the short aluminum wire in a compression mold according to the quality requirement, and then compressing and molding. The porosity after compression molding is less than or equal to 50 percent.
Preferably, the step (7) is: and (4) heating the sample compressed and molded in the step (6) to 450-480 ℃ for homogenization, and obtaining the sacrificial anode after homogenization. By heating for homogenization, the surface material of the compressed aluminum alloy wire begins to migrate, and at the same time, the aluminum alloy wire and the interface contact each other, forming a sintering neck after contact. By heating and homogenizing, larger pores formed during compression molding are gradually reduced and further converted into small pores, so that the compression strength of the sacrificial anode is obviously improved.
The temperature for heating and homogenizing cannot be too high, once the temperature is too high, the metal in the anode is melted, the formed pores disappear, the specific surface area is greatly reduced, and the working efficiency of the sacrificial anode is affected.
