为降低电镀镍层表面孔隙率,提高其耐腐蚀性能,采用由多种缓蚀剂及表面活性剂复配而成的水基封闭剂对电镀镍层进行封孔处理,通过腐蚀试验及电化学试验研究封闭处理后镍层耐腐蚀性能。结果表面:处理后镍层表面形成一层光亮透明的吸附膜,封闭了镍层表面孔隙,降低了镍层孔隙率,提高了其耐腐蚀性能。 In order to reduce the surface porosity of the electroplated nickel layer and improve the corrosion resistance of the electroplated nickel layer, a water-based sealing agent prepared by compounding a plurality of corrosion inhibitors and surfactants is used to seal the electroplated nickel layer, Experimental study of the corrosion resistance of nickel layer after closed treatment. Results: The surface of the treated nickel layer formed a bright and transparent adsorption film, which closed the pores on the surface of the nickel layer, reduced the porosity of the nickel layer and improved its corrosion resistance.
