英文摘要	本文采用电化学交流阻抗技术，研究了溶剂类型和组成对长醇酸清漆涂层在0.5 mol•L-1氯化钠中浸泡不同时间后耐腐蚀性能的影响. 结果表明，含有不同溶剂的长醇酸清漆的保护效率随着溶剂的挥发性增加或给定挥发溶剂的组成增多而提高，这也从扫描电子显微镜和X-射线能量散射谱分析结果得到证实. 此外，剥离面积，即金属表面由于有机涂层的剥落而导致腐蚀的面积，随溶剂挥发性的增强而减小.; The effects of solvent nature and composition on the anticorrosive properties of a long alkyd varnish after different days of immersion in 0.5 mol•L-1 NaCl were studied using electrochemical impedance spectroscopy. The protection efficiencies of the long alkyd varnishes containing different solvents increased with increasing the volatility of solvent or the composition of a given volatile solvent, which was confirmed with the observations using scanning electron microscopy and energy-dispersive X-Ray spectroscopy. The delaminated area, the area where the organic coating is detached from the metal surface leaving it unprotected, was found to decrease by increasing the volatility of solvent.; This work was supported by Corrosion Laboratory, Chemistry department, Faculty of science, Alexandria university.; This work was supported by Corrosion Laboratory, Chemistry department, Faculty of science, Alexandria university.; 作者联系地址：1.亚历山大大学化学系，易卜拉欣，426 信箱，亚历山大 21321，埃及; 2. 埃及涂料及化学工业公司(PACHIN)质量控制与检验部，埃及; 3. 现代涂料国际集团（Mido），伯格阿拉伯, 亚历山大，埃及.; Author's Address: 1.Chemistry department Faculty of Science Alexandria university, Ibrahimia, P.O.
