CONTRIBUTION TO THE STUDY OF CORROSION PHENOMENA IN INDUSTRIAL ATMOSPHERE THERMODYNAMIC APPROACH

摘要

The proposed corrosion resistance tests for electrical and electronic equipment involve setting up damp-air flows charged with H_2S, SO_2, NO_x and Cl_2 pollutants which dissolve on the surface films. A thermodynamic approach to reactions liable to occur on the metal surface is described with a view to classifying the various parameters to be allowed for interpreting corrosion phenomena both in industrial atmospheres and during kinetic tests or studies.
