| 摘 要： | 为了更深地认识CNTs对Ni—P镀层电化学腐蚀性能的影响，采用复合化学镀技术，通过向优化的化学镀溶液中加入碳纳米管的方法在45^#钢基材上制备了Ni—P—CNTs复合镀层，并用相同工艺在45^#钢基材上直接化学镀Ni—P镀层作为对比。采用SEM／EDAX，XRD和TEM综合分析了复合镀层的形貌和结构，分析表明：所得镀层以非晶结构为主，碳纳米管均匀分布在镀层中。采用动电位极化及交流阻抗技术对比研究了Ni—P—CNTs复合镀层及纯Ni—P镀层在0．5mol／LNaCl＋0．05mol／LH2sO4酸性溶液中的电化学腐蚀行为，腐蚀实验结果表明：在该介质溶液中，与不含碳纳米管的Ni—P镀层相比，Ni—P—CNTs复合镀层的自腐蚀电位和自腐蚀电流密度较低，耐均匀腐蚀性能得到明显改善；此外，碳纳米管的加入还明显提高了Ni—P镀层在该介质溶液中的耐点蚀性能。

| Abstract: | Ni-P-carbon nanotubes(CNTs) composite coatings as well as Ni-P coatings on 45 # steel were prepared by electroless plating in order to investigate the effect of CNTs on the corrosion of the electroless Ni-P coating.The characteristics and microstrucrure of the coatings were assessed by SEM/EDAX,XRD and TEM.The results indicate the co-deposited CNTs are homogeneously dispersed in the mainly amorphous Ni-P alloys.The electrochemical corrosion behavior of the electroless Ni-P and Ni-P-CNTs composite coating in... |
