摘要

采用电极阻抗法研究了锌片铬酸盐镀层在0.1mol/1NaClO4溶液中的耐蚀性。发现铬酸盐层的不均匀性和防腐性能与试样不同位置测得的阻抗数据之间存在相关性。阻抗测量和湿度测试的结果在实验误差范围内一致。

Study of chromate coatings by means of electrode impedance measurements

The corrosion resistance of chromate layers on zinc sheet was studied by electrode impedance measurements in 0.1 mol/1 NaClO₄ solutions. A correlation was found to exist between the inhomogeneity and corrosion protection of the chromate layers and impedance data measured at different spots of the specimen. The results of impedance measurements and humidity tests agreed within the experimental error.
