摘要
指出传统车身腐蚀分析时凭主观判断等级的局限性,认为电化学技术可以从更加微观和客观的角度对腐蚀行为作出分析。通过电化学经典的极化曲线和阻抗谱,可以对车身腐蚀机理进行解释。阐明了电化学技术在汽车腐蚀分析中的使用价值和应用前景。
The limitation of judging the grade subjectively in the conventional corrosion analysis of car body was pointed out.It was stated that electrochemical technologies could be used to analyze the corrosion behaviors more microscopically and objectively.The corrosion mechanism of car body can be interpreted through the measurement of electrochemical polarization curves and impedance spectra.The application value and prospect of electrochemical technologies in automobile corrosion analysis were expounded.
