High temperature annealing of the pickled sample, followed by secondary pickling desorption, has been attempted for further refining. 并嘗試在此后進(jìn)行高溫退火以再次造成表面擴散偏聚，然后繼以二次酸洗去吸附除雜。
Experiments indicate that acetone exhibits the best degreasing effect and that well-arranged porous anodic alumina film is obtained without annealing and electropolishing. 實(shí)驗結果表明，采用丙酮除油效果最好，不經(jīng)高溫退火和電化學(xué)拋光仍能得到高度有序的多孔陽(yáng)極氧化鋁膜，使制備工藝得到了簡(jiǎn)化。
