以往研究防锈油的电化学方法大多把涂油的金属试样浸没在溶液中,本文提出的新方法则在薄层水膜下进行。它是在特制的测试探头上涂油后覆盖镜头纸,置于湿热气氛中。已用该方法测试了极化电阻、极化曲线、交流阻抗等。
In the past, the electrochemical methods of anti-rust oil mostly immersed the oiled metal sample in the solution. The new method proposed in this paper was carried out under the thin water film. It is in a special test probe after the oil coated lens cover, placed in a hot and humid atmosphere. This method has been used to test the polarization resistance, polarization curve, AC impedance and so on.
