摘　　要：通过在EDTA(乙二胺四乙酸)络合SrSO4水溶液中进行电沉积的方法,在SS304基板上制备SrSO4涂层,通过扫描电镜(SEM)和X射线衍射仪(XRD)研究SrSO4晶体在电沉积过程中的生长规律。不锈钢阳极表面生成的SrSO4晶体在(210)晶面上出现了择优取向生长,而在(002)晶面上的生长受到抑制。SrSO4晶体在电沉积工艺中的生长过程主要受过饱和度控制。An electrochemical deposition process was used to deposit SrSO4 coatings onto the anode surface of SS304 stainless steel, from the Sr- EDTA chelating aqueous solution. The growth behavior of SrSO4 crystal during electrodeposition process was investigated by means of scanning electron microscopy（SEM） and X-ray diffraction（XRD） . Oriented crystal growth of SrSO4 occurred along（210） crystal plane, however, the crystal growth along（002） crystal plane is inhibited. The crystal growth behavior of SrSO4 during the electrodepositiou process is mainly controlled by supersaturation.
