摘　　要：本工作用分光光度法研究铝在0.4～1.6M氨基磺酸溶液中,在40°～70℃温度条件下的腐蚀速率。根据腐蚀速率数据,利用Mathur提出的经验公式计算出铝在氨基磺酸溶液中腐蚀反应的动力学参数K,B,E和A。把这些动力学参数同铁在氨基磺酸溶液中腐蚀动力学参数进行比较,结果表明,两种金属具有相近的能量障阻,动力学参数K、B和A随着金属特性和实验条件的不同而有差异。The corrosion rate of aliuminium in 0.4～1.6M sulfamic acid under the temperature of 40°～70℃ are investigated by the spectrophotometry. Based on the experimental corrosion rate data the several kinetic parameters of aluminium in salfamic acid have been calculated such as K, B, E and A with the experienced equation put forward by Mathur. Comparing them with the results of iron in sulfamic acid solution, it is found that energy barrier of corrsion reaction of iron and aluminium in sulfamic acid solution is almost the same. There is several difference in Several kinetic parameters differ with the difference of metallic characteristics and experimental condition.
