摘要： 应用原子力显微镜(AFM)探针刮伤技术研究缓蚀剂对探针诱导铜镍合金加速溶解作用的影响.实验表明,在1.5 mol/L NaC l和0.01 mol/L HC l溶液中,使用AFM探针在750 nN的力负载条件下以接触模式对铜镍合金表面持续扫描,会加速样品的溶解,并在探针刮擦区域形成蚀坑.将有机缓蚀剂十二胺及无机缓蚀剂铬酸钠添加到腐蚀介质中后,由于在合金表面形成了吸附膜和钝化膜,从而抑制探针刮擦引起的铜镍合金的加速溶解.

Abstract: The accelerated dissolution behavior of Cu-Ni alloy induced by AFM tip scratching and the inhibition effect of corrosion inhibitors were investigated. The results showedthat, with a tip loading of 750nN ,continuous scan for 30 min in a contact mode on 4×4 μm~(2) of copper-nickel alloy in 1.5mol/L NaCl and 0.01mol/L HCl could enhance the dissolution of the sample and produced pits on the scratched area. Adding inorganic inhibitors, sodium chromateand organic inhibitor dodecylamine, to the solution suppressed the dissolution of copper-nickel alloyinduced by tip scratching, respectively, by improving the surface passivationperformance of metal surface and forming adsorption films on copper-nickel alloy.

Key words: AFM tip scratching, Enhanced dissolution, Dodecylamine, Sodium chromate
