CORROSION OF GRAIN BOUNDARIES : INITIATION PROCESSES AND TESTING
Résumé
The aim of this paper is to discuss with numerous citations the processes which involve the initiation of the preferential dissolution at grain boundaries. Different parameters are considered : structural features, electrical properties, chemical properties, electrochemical and autocatalytic effects. Different tests are reviewed specialy with regard to segregation and structure effects. It is pointed out that the composition of grainboundaries is the most important since it modifies all the above-mentionned parameters.
