摘要

在不同的恒流密度和恒温条件下，对Ti-12合金进行了阳极氧化。在4mAcm -2 ~ 64mAcm -2的恒流密度和298 ~ 338K的温度条件下，研究了不同电解质中阳极膜的动力学。根据地层电压(V)与时间(t)的关系图，计算出地层速率。成膜速率和击穿电压随恒流密度的增大而增大，随温度的升高而减小。在室温下，与其他阳极氧化条件相同的电解液相比，在室温下的硫酸电解液的动力学更好。

Anodic Behaviour of Ti-12 in Various Electrolytes

Anodization of Ti-12 alloy has been carried out in various electrolytes at different constant current densities and temperatures. Kinetics of anodic films was studied in different electrolytes at different constant current densities ranging from 4mAcm -2 to 64mAcm -2 and at different temperatures ranging from 298 to 338K. From the plots of formation voltage (V) vs time (t), rates of formation were calculated. The rate of film formation and breakdown voltage increase with increase in constant current density while decrease with increase in temperature. The kinetics were found better in sulphamic acid electrolyte at room temperature compared to other electrolytes at the same anodizing conditions.
