针对飞机结构用铝合金在使用过程中容易发生腐蚀的缺点，采用化学镀工艺在2024航空铝合金表面制备了Ni-P合金、Ni-W-P合金和Ni-P-MWCNTs复合镀层3种镀层，研究多臂碳纳米管（MWCNTs）与Na₂WO₄添加量对镀层沉积速率的影响，并对三种镀层的表面微观形貌、结合力、疏水性能、耐蚀性等进行观察与分析。结果表明：Ni-P-MWCNTs复合镀层的沉积速率随着WMCNTs量的增加呈现先增后减，当WMCNTs加入量为0.3 g/L时，其沉积速率达到最大值10.03 mg/（cm²·h）。Ni-W-P合金镀层的沉积速率随着Na₂WO₄加入量的增大而增大并逐渐趋于稳定，当Na₂WO₄加入量为18 g/L时，沉积速率达到15.21 mg/（cm²·h）。几种试样的综合性能由强到弱依次为Ni-W-P镀层 > Ni-P-MWCNTs镀层 > Ni-P镀层 > 基体试样。

Aiming at the shortcomings of aluminum alloys for aircraft structures that were prone to corrosion during use, three types of cladding such as Ni-P alloy cladding, Ni-WP alloy cladding, and Ni-P-MWCNTs composite cladding were prepared on the surface of 2024 aviation aluminum alloy by chemical plating process. The effects of MWCNTs and Na₂WO₄ additions on the deposition rate of the claddings were studied, and surface micromorphology, adhesion, hydrophobic properties, corrosion resistance of the three coatings were observed and analyzed. The results show that the deposition rate of Ni-P-MWCNTs composite cladding increased first and then decreased with the increase of the amount of WMCNTs. When 0.3 g/L WMCNTs was added, the deposition rate reached a maximum of 10.03 mg/(cm²·h). The deposition rate of Ni-W-P alloy cladding gradually increased with the increase of the amount of Na₂WO₄ and gradually stabilized. When 18 g/L Na₂WO₄ was added, the deposition rate reached 15.21 mg/(cm²·h). The comprehensive performance of several samples in order from strong to weak was as follow:Ni-W-P coating > Ni-P-MWCNTs coating > Ni-P coating > matrix sample.
