鱼雷在发射管内长时间海水浸泡的情况下,鱼雷与海水直接接触部位会由于海水腐蚀而发生性能变化,因此需要对接触海水部位如壳体进行防海水腐蚀处理,以达到耐海水腐蚀使用要求.本文主要针对大面积接触海水的壳体、鳍舵和连接螺钉等腐蚀机理进行分析,提出可能采取的预防措施.%Under the circumstances that a torpedo is immersed in seawater for long in a launching tube, the performance of the parts that are directly contacting seawater could change because of corrosion. In order to protect the torpedo from the corrosion of seawater, anti-corrosion measures are necessary for the parts, such as the torpedo shell, which are contacting seawater. This article mainly analyses the mechanism of corrosion on the water-contacting parts such as shells, horizontal tail fin and rudder,and connecting screws etc. Meanwile, preventive measures are also proposed.
