Corrosion-resistant electroplated sucker rod and preparation method thereof

The invention provides a corrosion-resistant electroplated sucker rod and a preparation method thereof, and belongs to the technical field of well drilling. Comprising the following steps: S1, pretreatment; s2, preparing an electroplating solution; and S3, electroplating. According to the corrosion-resistant electroplated sucker rod prepared through the method, a La/Ce doped Ni-W-graphene coating is formed on the surface of the sucker rod through an electroplating method, the coating is fine and smooth, the corrosion resistance and wear resistance of the sucker rod are greatly improved, the mechanical property is improved, the service life of the sucker rod is prolonged, and the service life of the sucker rod is prolonged. The device is suitable for high-temperature and high-pressure high-corrosive environments of H2S, Cl , CO2 and mixed media thereof. 本发明提出了一种耐腐蚀电镀抽油杆及其制备方法，属于钻井技术领域。包括以下步骤：S1.预处理；S2.配置电镀液；S3.电镀。发明制备的耐腐蚀电镀抽油杆通过电镀的方法在抽油杆表面形成一层La/Ce掺杂的Ni-W-石墨烯镀层，镀层细腻、平整，极大的提高了抽油杆的耐腐蚀以及耐磨性能，力学性能提高，延长了其使用寿命，适用
