【摘要】 采用表面能谱分析、电化学以及恒温恒湿、交变湿热等试验方法,研究了酸洗工艺对无间隙原子钢(IF钢)腐蚀性能的影响。结果表明,5%盐酸酸洗后IF钢表面Mn元素含量降低,耐腐蚀性提高;盐酸酸洗提高了IF钢的抗腐蚀能力,消除了IF钢表面Mn元素的富集。更多还原

【Abstract】 he effect of pickling on thecorrosion resistance of interstitial free steel ( IF steel) was studiedby using energy dispersive X-ray analysis, electrochemical test,corrosion test at constant temperature and humidity, and alterna-ting damp-and-hot corrosion test. It has been found that the con-tent of manganese on the surface of IF steel is reduced after beingdipped in 5 % hydrochloric acid bath, and hence the corrosion re-sistance of the IF steel is increased. The reason might be thatetching in hydrochloric acid contributed to eliminaton of the en-richment of manganese on surface of IF the steel, leading to in-creasing corrosion resistance of the steel.更多还原
