研究铝在硫酸溶液中复合阳极氧化时的铝试件表面温度的变化行为。实验表明，由于粉体的加入可明显降低铝试件表面的温度，其下降程度与粉体本性有关。随着粉体加入量的增加，铝试件表面温度下降也愈大，但到一定加入量后，会出现一个稳定值。铝的复合阳极氧化可明显提高阳极氧化膜层厚度，其主要原因是由于铝试件表面温度降低所致。
The surface temperature change of Al test pieces in H2SO4solution during composite anodizing is researched. The test result shows that the surface temperature of Al pieces is evidently decreased because of the presence of insoluble powders, the extent of temperature decrease relates to insoluble powders' character. With more amount insoluble powders are added, the surface temperatures of Al pieces is even more reduced and finally towards a steady value. The thickness of anodizing film is evidently increased because of composite anodizing. The main reason is the decrease of surface temperature of Al pieces.
