| 摘 要： | 高强度铝合金被广泛用于飞机结构中，然而，这一系列铝合金抗腐蚀和耐磨性差，限制了其应用。而Ni-P合金镀层具有高的硬度和抗腐蚀性能等优异特点，成为增强表面性能的常用手段。采用化学镀镍工艺在铝合金（6061）表面进行化学镀镍处理，研究了pH值、沉积温度和沉积时间对沉积速率的影响。分析了化学镀镍层的成分和组织形貌，同时对镀层的硬度、抗腐蚀性进行了表征。试验表明，在铝合金表面化学镀镍可以显著提高铝合金表面的硬度，并改善其在5％NaCl溶液中的耐蚀性。

| Abstract: | High strength aluminium alloys are widely used in airframe construction.However,this series of alloys are susceptible to corrosion and wear to limit their usefulness.As is well known,nickel-phosphorous(Ni-P) plating exhibits high hardness and corrosion-resistant and usually is applied to improve the properties of surface.In this study,electroless Ni-P alloy plating on aluminum alloy and the effects of pH value,temperature and deposition time on deposition rate were investigated.Deposits composition and surf... |
