摘　　要：应用SEM和XPS研究了退火工艺对热浸镀锌440 MPa IF-HS钢(高强度无间隙原子钢)板表面氧化物形貌、尺寸和分布状态的影响。结果表明,随着退火温度的升高和保温时间的延长,钢板表面氧化物数量先增加后减少,尺寸逐渐增大,其成分主要为MnO、Mn(PO)和NbN,并得出有利于钢板表面浸润性的退火工艺为850℃×60 s。The effect of annealing process on surface oxides morphology,size and distribution of hot dip galvanizing 440 MPa IF-HS steel（high strength interstitial free steel） was investigated by scanning electron microscope（SEM） and X-ray photoelectron spectroscopy（XPS）.The results show that the oxides amount is firstly increased and then decreased,and the oxides sizes are increased with the increasing of annealing temperature and time.The main oxides are MnO2,Mn3（PO4）2 and NbN,moreover it is found that the suitable annealing process is 850 ℃×60 s thus beneficial to wettability of the steel surface.
