Arc spraying can greatly improve the corrosion resistance of circular plate, select the appropriate spraying material and optimize the process parameters are the premise to achieve the best anti-corrosion effect, arc spraying is an efficient surface engineering technology, widely used in many industries, including aerospace, Marine, automotive, electric power and other fields. It forms a solid coating by creating an arc between two wires, melting the metal and atomizing it into micro-particles, which are then sprayed onto the substrate surface with compressed air or other gases. When applied to objects with more regular shapes such as round plates, arc spraying can provide the following advantages:
1, the formation of a barrier layer: arc spraying can form a continuous and dense layer of metal or alloy coating on the surface of the round plate, effectively blocking the corrosive medium (such as water, oxygen, chemicals, etc.) and the direct contact with the base metal, thereby delaying or preventing the corrosion reaction.
2, sacrificial anode effect: in some cases, the selected spray material (such as zinc, aluminum) is more active than the base metal, and the oxidation reaction is preferred in the corrosive environment, protecting the base metal below from corrosion, which is the so-called sacrificial anode protection principle.
3, increase the mechanical sealing: the coating formed by spraying can fill the original fine cracks or pores on the surface of the round plate, improve the integrity and sealing of the surface, and reduce the possibility of penetration of corrosive media.
4, self-healing ability: Some spray materials have a certain self-healing characteristics, even if the coating is locally damaged, it can repair small cracks under certain conditions, and continue to maintain the anti-corrosion effect.
5, improve hardness and wear resistance: the strong coating can resist physical wear, indirectly reducing the risk of corrosion caused by wear exposure to the matrix.
It should be noted that although arc spraying can greatly improve the corrosion resistance of the round plate, it is still necessary to check and maintain regularly in extreme environments or under prolonged exposure to ensure that the coating is intact. In addition, it is recommended to collaborate with a professional thermal spraying service company to obtain a targeted solution.
