摘　　要：铜合金作为船舶螺旋桨主要的组成材料,它的对抗海水腐蚀的性能比较好、同时具有较高的延展率和比较好的冲击韧性、适合铸造的加工方法、性价比较好。然而,由于海洋工作环境所致,使得船舶需要向提升体型与提升速度的方向前进,所以对动力输出,也就是螺旋桨系统的要求越来越高。因此,研制出机械性能好、耐空泡腐蚀、剥蚀性能好、腐蚀疲劳强度高的螺旋桨材料成为提高海洋设备性能的关键。本文针对船舶航行中出现的空泡腐蚀问题,概述了铜合金空泡腐蚀的机理,并总结了控制铜合金空泡腐蚀的常用方法。As the main component materials of ship propeller,copper alloys have good resistance to seawater corrosion,high ductility and good impact toughness,suitable for casting processing and good cost performance.However,due to the marine service environment,ships are needed to develop in the direction of lifting shape and speed,so the requirements for power output,that is,propeller system,are becoming higher and higher.Therefore,the development of propeller materials with good mechanical properties,good cavitation corrosion and denudation resistance and high corrosion fatigue strength has become the key to improve the performance of marine equipment.In this paper,the cavitation corrosion mechanism of copper alloy is summarized,and the common methods to control the cavitation corrosion of copper alloy are summarized.
