Steel 12kh18n10t Crevice Corrosion Under Heat Transfer Conditions

摘要

During heat transfer from metal to solution, local metal activation occurs more readily within a crevice than under isothermal conditions, i.e., both for metal open surface temperature and also for crevice bottom temperature. Metal within a crevice is activated more readily the higher the heat flow density. Disruption of passivity is more likely to occur in the form of a corrosion spot close to a crevice bottom.
