摘　　要：使用电化学、恒温恒湿和交变湿热的大气腐蚀实验方法,使用两种不同频率的超声波对电解钝化无间隙原子钢(IF钢)的腐蚀电化学行为进行了研究。结果表明,当使用较低频率的超声波时,可以使IF钢阳极电解钝化的耐蚀性提高。而外加较高频率的超声波时,使IF钢阳极电解钝化的耐蚀性降低。超声波对IF钢电解钝化试样耐蚀性的影响主要是由超声空化作用、洗脱作用以及升温作用等几个方面来作用的。The corrosion study methods,which consisted electrochemistry method,contant temperature and humidity experiment,and alternating humidity and temperature experiment,were carried out to investigate the effect of corrosion and electrochemical behavior on Interstitial Free Sheet(IF) steel using ultrasonic electrolytic passivation.It was shown that the corrosion resistance of electrolytic passivation IF steel was increased when using lower frequency ultrasonic,while the higher frequency ultrasonis can reduce the corrosion resistance of electrolytic passivation IF steel.The main effect factors of ultrasonic for the electrolytic passivation IF steel were related to the action of ultrasonic cavitation,elution and elevated-temperature.
