摘要:
为提高建筑用铝型材的耐久性，解决其在应用中易受腐蚀和磨损的问题，本研究对建筑用铝合金表面电镀工艺及应用性能进行分析。实验选用建筑领域常用的Al-Cu-Mg-Mn铝合金型材作为基材，采用六水硫酸镍、柠檬酸、硼酸、氨水、十二烷基硫酸钠以及石墨烯等试剂制备电镀液。通过调整石墨烯含量制备了3组电镀试件，并对其微观形貌、物相组成、电化学耐腐蚀性能和耐磨性能进行测试。结果表明：在石墨烯含量为3 g/L的电解液中制备的试件表现出最优异的综合性能，其镀层结构致密无缺陷，自腐蚀电位显著正移至?0.15 V(vs. SCE)，自腐蚀电流密度最低，电荷转移电阻最大，耐腐蚀性能显著优于其他两组试件。同时，该试件在摩擦测试中表现出稳定且最低的摩擦系数，磨损失重最小，磨损速率最低，磨损形貌损伤轻微(以氧化磨损和轻微粘着磨损为主)，耐磨性能最优。由此证明，在镍基电镀液中添加3 g/L石墨烯对铝型材进行表面处理，可显著提升其耐腐蚀和耐磨性能，这为建筑用铝型材的实际应用提供了一种高效、可行的表面处理方案。
Abstract:
In order to improve the durability of aluminum profiles for construction and solve their susceptibility to corrosion and wear in application, the surface electroplating process and application performance of aluminum alloys for construction were analyzed. The experiment selected Al-Cu-Mg-Mn aluminum alloy profiles commonly used in the construction field as the substrate, and prepared electroplating solutions using reagents such as nickel sulfate hexahydrate, citric acid, boric acid, ammonia water, sodium dodecyl sulfate, and graphene. Three sets of electroplated specimens were prepared by adjusting the graphene content, and their microstructure, phase composition, electrochemical corrosion resistance, and wear resistance were tested. The results show that the specimens prepared in an electrolyte with a graphene content of 3 g/L exhibit the best comprehensive performance, with a dense and defect free coating structure, a significant positive shift in self-corrosion potential to ?0.15 V (vs. SCE), the lowest self-corrosion current density, the highest charge transfer resistance, and significantly better corrosion resistance than the other two groups of specimens. At the same time, the specimen exhibits stable and lowest friction coefficient, minimal wear loss, lowest wear rate, slight wear morphology damage (mainly oxidative wear and slight adhesive wear), and the best wear resistance performance in the friction test. This proves that adding 3 g/L graphene to nickel based electroplating solution for surface treatment of aluminum profiles can significantly improve their corrosion resistance and wear resistance, providing an efficient and feasible surface treatment solution for the practical application of aluminum profiles in construction
