Influence of heat flux on localised corrosion of stainless steel under boiling conditions

Abstract

The article deals with the influence of heat flux on localised forms of corrosion of stainless steels under the conditions of phase transition on a metal surface. The observations focused on the influence of the initiation and propagation of pitting corrosion and stress corrosion cracking. Pitting corrosion was tested in the environment of 0.6% FeCl 3 þ 0.3% EDTA þ 0.1% HCl, the susceptibility to stress corrosion cracking was verified in 35% MgCl 2 . The tests proved a negative influence of heat flux on the initiation and propagation of non-uniform corrosion.

“…Trochu odlišný je vliv, pokud na povrchu probíhá i fázový přechod, tzn. vypařování vody z elektrolytu [3]. U nižších úrovní tepelného toku dochází pod bublinkami ulpělými na povrchu po delší dobu ke tvorbě štěrbinové koroze.…”
