【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。更多还原

【Abstract】 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 electrodeposition process is mainly controlled by supersaturation.更多还原
