摘　　要：探讨了微弧氧化溶液体系电导率对陶瓷层生长速度的影响 ,并以击穿场强作为反映陶瓷层致密度的物理参量 ,测定了实验条件下电导率与击穿场强的关系。结果表明 ,陶瓷层的生长速度与溶液电导率之间有近似线性的正比增长关系 ;Effect of conductivity of solution on growing rate of micro\|arc oxidation ceramic coatings is studied. The relationship between the conductivity of solution and the insulating intensity that reflects the compact of the coatings is measured in terms of experiment. The results show that there is a approximately linear relationship between the growing rate and the conductivity of solution, and the insulating intensity of coatings, i.e, density of the coating, is increase at beginning and then decrease as the increase of conductivity of solution.
