高能等离子喷涂纳米Al2O3—13％TiO2涂层的组织与耐蚀性能

刘焱飞、刑书明、龚志强 等 4 位作者2011-01-01Acta Scientiarum Naturalium Universitatis Sunyatseni

本文采用高能等离子喷涂方法制备了纳米Al2O3-13％TiO2涂层。通过X射线衍射法（XRD）分析了涂层物相成分，利用电子显微镜观察涂层截面组织形貌，并检测涂层盐雾腐蚀性能与人造海水耐蚀性能。结果表明：该涂层显微组织结构不同于普通等离子啧涂的Al2O3-13％TiO2涂层；涂层在人造海水环境下平均腐蚀率为0．025g／m^2·h；盐雾气氛平均腐蚀率为0．0136g／m^2·h。

熔盐Na3AlF6-K3AlF6-AlF3系中氧化铝的饱和溶解度

王家伟、陈朝轶、靳学利2011-01-01有色金属：冶炼部分

采用旋转氧化铝片法研究了Na3AlF6-K3AlF6-AlF3体系的氧化铝溶解度，其中电解质组成为：K3AlF6占K3A1F6和Na3AlF6质量总和的O～50％，A1l3占23％～29％，对该范围的氧化铝溶解度提出了相关系数为0．994的经验计算公式和等氧化铝浓度图。研究结果表明：随着AlF3含量增加，氧化铝溶解度降低，AlF3含量小于25％的区域氧化铝溶解度较高；随着钾冰晶石的增加，均出现相同的趋势，氧化铝溶解度先增加后减少，在K／（K＋Na）含量为10％～40％时相对较高些；为了确保氧化铝溶解度大于4％，熔体温度必须高于840℃，故该复合冰晶石体系比较有潜力实现的低温电解温度是850℃。
