Abstract

CORROSION TESTS WITH ULTRASONICS ? IT is well known that the corrosion of iron, zinc, aluminium, magnesium, etc., is slower in moving water than in water at rest. This has been explained by the protective oxide film theory, i.e. the supply of oxygen to the metal surface is more adequate in moving water for the formation of complete films than in water at rest. When ultrasonic waves are used to stir the corroding solution in which the metal is immersed, the wet corrosion may be explained by a colloid science argument rather than by oxide film theory.
