摘要:
针对高压电器用铝合金类零部件在服役过程中易发生腐蚀的现象，采用电镀工艺在6063铝合金表面制备银镀层，对中间铜镀层、预镀银层的表面微观形貌、耐蚀性进行观察和分析，研究镀铜工艺对镀层耐蚀性能的影响。结果表明，镀层致密度与耐蚀性能呈正比；低浓度镀铜溶液条件下，镀层致密度及耐蚀性能得到了提升；镀液中的杂质会影响镀层沉积的致密度，导致耐蚀性能降低；镀液添加剂对镀层致密度及耐蚀性能无明显改变。
Abstract:
In response to the corrosion phenomenon of aluminum alloy components used in high-voltage electrical appliances during service, a silver coating was prepared on the surface of 6063 aluminum alloy using electroplating technology. The surface microstructure and corrosion resistance of the intermediate copper and silver coatings were observed and analyzed, and the influence of copper plating technology on the corrosion resistance of the coating was studied. The results indicate that the density of the coating is directly proportional to its corrosion resistance. Under low concentration copper plating solution conditions, the density and corrosion resistance of the coating have been improved. Impurities in the plating solution affect the density of the deposited coating and reduce its corrosion resistance. The additive in the plating solution has no significant effect on the density and corrosion resistance of the coating
