摘 要
针对高强钢构件在“三高一强”极端环境下对高耐蚀防护技术的迫切需求,系统开展了电刷镀锌镍合金工艺优化研究。重点探讨了镀液Ni摩尔分数(20%~40%)、温度(10~30℃)及工作电压(6~10 V)等关键工艺参数对镀层微观结构及耐腐蚀性能的影响规律。研究结果表明:当Ni摩尔分数为30%、镀液温度为20℃、工作电压为8~9 V时,可获得镍含量(质量分数)约9.15%、具有均匀细晶结构的致密镀层,其在5%(质量分数) NaCl溶液中的腐蚀电流密度最低可达4.62×10-6A/cm2,表现出最优的耐腐蚀性能。本研究确立的优化工艺参数可为高强钢构件现场刷镀修复提供有效的技术支撑,在装备再制造与长效防护领域具有重要的工程应用价值。
Abstract
In response to the urgent demand for high-corrosion-resistance protection technology of high-strength steel components under the "three highs and one strong" extreme environment, a research on the optimization of the zinc-nickel alloy brush plating process was systematically conducted. The focus was on exploring the influence of key process parameters, including the molar ratio of Ni in the plating solution (20%-40%), temperature (10-30 ℃), and working voltage (6-10 V), on the microstructure and corrosion resistance of the coating. The research results indicated that when the molar ratio of Ni was 30%, the plating solution temperature was 20 ℃, and the working voltage was 8-9 V, a dense coating with a uniform fine-grained structure and a nickel content of approximately 9.15% could be obtained. This coating exhibited the lowest corrosion current density of 4.62×10-6 A/cm2 in a 5% (mass fraction) NaCl solution, demonstrating optimal corrosion resistance. The optimized process parameters established in this study could provide effective technical support for on-site brush plating repair of high-strength steel components and had significant engineering application value in the fields of equipment remanufacturing and long-term protection.
