中文摘要:
      目的 研究B10铜镍合金在青岛港口海水全浸区的腐蚀规律。方法 进行室内模拟海水全浸试验以及港口海域实海全浸试验,利用三维视频拍照、电化学测试和失重分析等手段,对比分析了B10铜镍合金在海水全浸环境中的腐蚀形貌、腐蚀速率以及点蚀深度。结果 室内模拟环境中,随着浸泡周期增长,B10铜镍合金点蚀深度有增大趋势;实海环境中B10铜镍合金180 d腐蚀速率和点蚀深度均小于室内模拟环境;室内模拟环境中,B10铜镍合金的主要腐蚀产物为Cu2O和Cu2(OH)3Cl和Cu(OH)2组成。较高含量的Cu2O对海生物污损起到抑制作用。结论 由于海水环境不同,B10铜镍合金在室内模拟试验与实海试验中腐蚀形貌、腐蚀速率和点蚀深度均存在明显差异。
英文摘要:
      The work aims to study the corrosion regularity of B10 copper-nickel alloy in the seawater immersion zone of Qingdao harbor. The full immersion experiment was carried out respectively in indoor simulated seawater and real seawater of harbor. The corrosion morphology, corrosion rate and pitting depth of B10 copper-nickel alloy after full immersion in seawater were compared and analyzed by 3D video photography, electrochemical test and weightless analysis. In the indoor simulated environment, there was an increasing trend for the pitting depth of B10 copper-nickel alloy as the immersion period increased. The corrosion rate and pitting depth of B10 copper-nickel alloy after immersion for 180 days in the real sea environment were smaller than those in the indoor simulated environment. In the indoor simulated environment, the main corrosion products of B10 copper-nickel alloy were Cu2O, Cu2(OH)3Cl and Cu(OH)2. Higher levels of Cu2O inhibited the marine fouling. Due to different seawater environments, there are significant differences in corrosion morphology, corrosion rate and pitting depth of B10 copper-nickel alloy in indoor simulation test and real sea test.
