铜合金在海洋环境中以均匀腐蚀为主,其中以全浸最重、潮差次之、飞溅最轻。随暴露时间的增加,平均腐蚀速度降低。在泥沙冲击腐蚀条件下,多数铜合金腐蚀速度增大。HAl77-2A板在全浸和潮差区显示出最优的耐蚀性。半硬态QSn6.5-0.1合金板材在全浸区的腐蚀速度较低,特别是对泥沙冲击腐蚀不敏感。随着暴露时间增加,抗海洋生物附着能力亦降低,死亡海洋生物腐烂产生的硫化物引起严重局部腐蚀。双相黄铜腐蚀速度高于单相黄铜。BFe30-1-1管组织不均匀导致晶间腐蚀。由于残余应力影响,管材腐蚀速度大于板材。多数铜合金腐蚀速度与时间关系服从幂函数规律。
Copper alloy in the marine environment to uniform corrosion, of which the most full dip, tide second, splash the lightest. With the increase of exposure time, the average corrosion rate decreased. Corrosive erosion in sediment conditions, the majority of copper alloy corrosion rate increases. HAl77-2A plate in the dip and tidal zone showed the best corrosion resistance. Semi-hard QSn6.5-0.1 alloy sheet corrosion rate in the whole immersion zone is low, especially for the impact of sediment erosion is not sensitive. As exposure time increases, anti-marine attachment capacity also decreases, resulting in serious localized corrosion of sulfides resulting from the decay of dead marine organisms. Duplex brass corrosion rate higher than single-phase brass. BFe30-1-1 uneven tube structure leads to intergranular corrosion. Due to residual stress, pipe corrosion rate is greater than the plate. The corrosion rate of most copper alloys and the time obeys the law of power function.
