船舶杂散电流腐蚀与防护案例分析

Study on Stray Current Corrosion and Protection of Ships

船舶杂散电流腐蚀是一种电化学腐蚀。本文以某船舵叶、美人架、螺旋桨异常腐蚀现象分析船舶杂散电流发生的原因、危害及防护措施,对于类似船舶的设计建造可引以为鉴。

The stray current corrosion of a ship is an electrochemical corrosion. Taking the abnormal corrosion of the rudder blade, the propeller and its shaft bracket as examples, the cause, harm and protective measures of stray current of a ship, are analyzed The results is helpful to designers in the design and construction of ships.
