Abstract The relatively limited data for the corrosion and pitting of high nickel alloys are reviewed herein and time-dependent trends developed for exposures in marine and atmospheric environments. Data sets for average or ‘uniform’ corrosion losses that are sufficiently extensive show topological consistency with the bimodal functional model previously observed for steels and various copper-nickel and aluminum alloys. Trends for localized corrosion (pit or crevice depth) plateau after earlier rapid growth over several years. The present observations add support to the concept that there is a change in corrosion behavior with extended temporal exposure and that this is generally consistent for many alloys. They also reinforce that shorter-term observations of maximum corrosion or pit depth usually is unsuited for extrapolation to, and prediction of, longer-term corrosion as typically important for practical infrastructure applications.

长期海洋和大气暴露中高镍合金腐蚀的非线性趋势

摘要 本文回顾了高镍合金腐蚀和点蚀的相对有限的数据，并针对海洋和大气环境中的暴露情况制定了随时间变化的趋势。足够广泛的平均或“均匀”腐蚀损失的数据集显示了与先前观察到的钢和各种铜镍和铝合金的双峰功能模型的拓扑一致性。经过几年早期快速增长后局部腐蚀（坑或裂缝深度）平台的趋势。目前的观察结果支持这样一个概念，即随着时间的延长，腐蚀行为会发生变化，这对于许多合金来说通常是一致的。他们还强调，对最大腐蚀或凹坑深度的短期观察通常不适合外推，
