铜表面BTA联合TTA自组装膜在柠檬酸中耐蚀性能研究
Study on the corrosion resistance of BTA and TTA composite self-assembled films on copper surface in citric acid
摘要
Abstract
Aiming to solve the problem of poor performance of benzotriazole(BTA)self-assembled films on the pure copper surface in high-temperature citric acid solutions,the corrosion inhibition rate of the compounding system containing BTA,tolyltriazole(TTA),and ethanolamine(EA)in a 4%citric acid solution under a water bath at 60 ℃ was evaluated using inductively coupled plasma optical emission spectrometry.According to the orthogonal test results,the optimal mass fractions of BTA,TTA,and EA in the ternary system were determined to be 0.150 0%,0.075 0%,and 0.005 0%,respectively,achieving a corrosion inhibition rate of 98.2%.The corrosion resistance,microstructure and surface composition,and hydrophobic properties of the self-assembled films were characterized using electrochemical workstation,scanning electron microscope,Fourier transform infrared spectroscopy,energy dispersive X-ray spectrometer,and interfacial tensiometer.The results indicate that,compared with the single component system of BTA with a mass fraction of 0.150 0%,the ternary compound group demonstrated a better synergistic effect,which altered the structure of the self-assembled film and improved its corrosion resistance.关键词
