The invention relates to a filiform corrosion resistant zinc-aluminum-magnesium coated steel plate and a preparation method thereof, and belongs to the technical field of coating. The coated steel plate comprises a steel substrate and a zinc-aluminum-magnesium coating attached to at least part of the surface of the steel substrate, and the zinc-aluminum-magnesium coating comprises the following chemical components in percentage by mass: 1-4% of Mg, 1-4% of Al, 0.5-2% of Bi and a substrate element Zn; and the zinc-aluminum-magnesium plating layer contains an Mg-Bi compound. Bi is added into the plating layer, the Bi and Mg in the plating layer form an Mg-Bi compound, the Mg-Bi compound exists in the plating layer in a granular or ellipsoidal shape, on one hand, part of magnesium is consumed, the number of eutectic structure Mg-Zn compounds in the plating layer is reduced, and therefore the sensitivity of filiform corrosion is reduced; and on the other hand, the Mg-Bi compound also has certain corrosion resistance, so that the overall corrosion resistance of the coating can be further enhanced.

A proper amount of Sb is added into the plating layer, Sb and Mg react to generate an Mg-Sb compound, on one hand, the Mg-Sb compound consumes part of magnesium, the number of eutectic structure Mg-Zn compounds in the plating layer is reduced, and therefore the sensitivity of filamentous corrosion is reduced; and on the other hand, the Mg-Sb compound also has certain corrosion resistance, so that the overall corrosion resistance of the coating can be further enhanced.

This utility model discloses a high tensile strength and corrosion resistance cable for offshore wind power, comprising a cable core consisting of a central tensile rope and multiple moisture-proof insulated cores; the moisture-proof insulated cores are tangent to the central tensile rope; moisture-proof and water-blocking filler is used to fill the gaps in the cable core; a shielding aluminum-plastic composite tape is wrapped around the cable core; a corrosion-resistant composite layer is provided outside the shielding aluminum-plastic composite tape; a flexible buffer layer is extruded outside the corrosion-resistant composite layer; a steel tape armor layer is provided outside the flexible buffer layer; a PTFE film tape is overlapped and wrapped around the steel tape armor layer; and an outer sheath is extruded outside the PTFE film tape. By optimizing the cable structure and material selection, the tensile strength and corrosion resistance of the cable are improved, while maintaining the cable's flexibility and service life, to meet the high requirements of offshore wind farms for cables.
