       US 5370776 

 

　　A simple, expedient method for measuring the effectiveness of a corrosion inhibitor provided to a metallic surface by a surface layer, wherein the layer is formed by use of the corrosion inhibitor is a corrosive fluid. The method employs the measuring of a high frequency phase angle as an indicator of inhibitor effectiveness.

 

　　提供一种测量金属表面腐蚀抑制剂表层有效性的简单、权宜的方法，其中使用的缓蚀剂形成的表层是一种腐蚀性流体。 该方法采用测量高频率相位角，作为抑制剂的效果的指标。
