Abstract Dependence of the tribocorrosion behaviour of nickel-aluminium bronze (NAB) on load in artificial seawater was investigated. Results from electrochemical measurements revealed that, decreases in the corrosion potential and polarisation resistance were induced by increased load, implying an increased susceptibility to corrosion. Quantitative calculations indicated that the synergy of wear and corrosion was crucial, particularly for the corrosion-accelerated wear component, which combined with pure mechanical wear were the predominant cause of degradation of NAB. Moreover, selective α-phase corrosion behaviour was observed, with the boundaries of intermetallic κ III and κ IV precipitates corroded preferentially.

人工海水中镍铝青铜的载荷相关摩擦腐蚀行为

摘要 研究了人工海水中镍铝青铜（NAB）摩擦腐蚀行为对载荷的依赖性。电化学测量结果表明，腐蚀电位和极化电阻的降低是由负载增加引起的，这意味着对腐蚀的敏感性增加。定量计算表明磨损和腐蚀的协同作用是至关重要的，特别是对于腐蚀加速磨损部件，它与纯机械磨损相结合是 NAB 降解的主要原因。此外，观察到选择性 α 相腐蚀行为，金属间 κ III 和 κ IV 析出物的边界优先腐蚀。
