芬兰破冰船潮湿表面的腐蚀往往十分严重。近十年来,三种新的防腐方法得到了成功应用:使用专用的无溶剂环氧漆;使用不锈钢螺旋桨和采用外加电流阴极保护。由这些改进所取得的经验是可靠的。它可以延长进坞周期,还能减少燃料消耗。未来的课题是研究在破冰船壳体的水线部位采用不锈钢。但这会带来新的腐蚀危险。为了研究电偶效应,在波罗的海海水中测量了不锈钢-碳钢电偶的断路电位。还对船头有不锈钢衬层的小船的底部进行了电位测量。
Finnish icebreaker wet surface erosion is often very serious. In the last decade, three new anticorrosive methods have been successfully applied: using a proprietary solvent-free epoxy paint; using a stainless steel propeller and applying an impressed current cathodic protection. The experience gained from these improvements is reliable. It can extend the dock cycle, but also reduce fuel consumption. The topic for the future is to study the use of stainless steel in the waterline sections of icebreaker housings. But this will bring new dangers of corrosion. In order to study the galvanic effect, the open circuit potential of a stainless steel-carbon steel galvanic was measured in Baltic Sea water. The bottom of the boat with stainless steel lining was also subjected to potential measurements.
