摘　　要：采用失重法、极化曲线法、交流阻抗法研究泛昔洛韦与十二烷基苯磺酸钠(SDBS)对黄铜在3.0%NaCl介质中的缓蚀作用。结果表明:当泛昔洛韦浓度为0.40 g/L、SDBS浓度为0.35g/L时,其复配缓蚀效率达到93.5%。泛昔洛韦和SDBS对黄铜的缓蚀机理分析表明,泛昔洛韦在铜合金表面通过物理与化学吸附共同作用形成保护膜,与SDBS发挥了极好的协同作用,阻碍Cl^-对铜的侵蚀,实现了对铜的高效保护。The inhibition effects of famciclovir and sodium dodecylbenzenesulphonate （SDBS） on corrosion of brass in 3.0% NaCI solution have been investigated using polarization curves, electrochemical impedance spectroscopy and weight loss measurements. It has been shown that the addition of the mixture of famciclovir and SDBS enhanced the inhibition efficiency to about 95% at the concentration of 0.40 g/L and 0. 35 g/L respectively. It is probabily ascribed to the formation of a adsorption film on brass through physical and chemical joint action by famciclovir, which exibits an excellent protection of brass with SDBS by synergistic effect,preventing the attack of Cl- , and protects the brass from corrosion.
