| Résumé : |
The préparation of a surface frequently has a considerable influence on its subsequent corrosion behavior. it ia accordingly necessary to arrive at the best possible definition of the surface state for all corrosion test. The distinction made by P.A Jacquet between the three surface stat characteristics is : geometrical characteristics, chemical characteristics. They may be characterized by an electrochemical method involving the coulometric reduction of this oxide layer in sulphuric acid. Physical or structural characteristics: the superficial cold-work may be assessed by metallographical techniques on sections and enlargement of the X-ray diffraction lines. Chemical reactions : pitting corrosion in ferric chloride is greatly influenced by the surface roughness. The effect of initial passivation is very marked in all corrosive media which are not themselves passivating |
