化学镀Ni-Sn-P复合镀层的耐腐蚀性能
|
摘要
通过极化曲线、电化学阻抗谱(EIS)电化学实验及均匀腐蚀实验研究了化学镀Ni-Sn-P复合镀层分别在5%H_2SO_4和3.5%NaCl不同腐蚀溶液中的耐腐蚀性,探究了不同Sn颗粒含量对Ni-Sn-P复合镀层耐腐蚀性能的影响。结果表明,当Sn含量为2.0 g/L时,Ni-Sn-P复合镀层的失重最小,其抗腐蚀性能最好。当Sn含量高于2.0 g/L时,镀层失重增大,孔隙率上升,Ni-Sn-P复合镀层的耐腐蚀性能降低。在两种腐蚀溶液中,Ni-Sn-P复合镀层相比于Q235基体和Ni-P镀层具有更正的腐蚀电位,更高的传荷电阻值(R_(ct)),更小的双电层电容值(C_(d1)),更低的失重速率。这说明Ni-Sn-P复合镀层在不同酸性的腐蚀介质中的耐蚀性比Ni-P镀层及基体的显著增强。
The corrosion resistance behaviors of Ni-Sn-P composite coating were investigated by polarization curve,electrochemical impedance spectroscopy(EIS)and uniform corrosion test in 5.0%H_2SO_4 and 3.5% NaCl solutions.The effects of different content of Sn particle on the corrosion resistance of Ni-Sn-P composite coating were studied.The results show that the mass loss of Ni-Sn-P composite coating is lowest when the content of Sn is 2.0 g/L,indicating that Ni-Sn-P composite coating has the best corrosion resistance.The mass loss and porosity both increases when the content of Sn is greater than 2.0g/L,resulting in the decrease of corrosion resistance.In two corrosion solutions,compared with Q235 and Ni-P coating,Ni-Sn-P composite coating has a positive shift of corrosion potential,higher corrosion transfer resistance(R_(ct)),smaller double layer capacity(C_(d1))and lower weight loss rate,which indicates that Ni-Sn-P composite coating exhibits better corrosion resistance than that of Ni-P coating and Q235 matrix.
