EFFECT OF ULTRASONIC CLEANING OF CORROSION RESISTANCE OF PHOSPHATE-COATED PANELS

Abstract

Zinc and manganese phosphated steel panels were exposed to high frequency vibrations in various media to determine the effect of this cleaning procedure on the corrosion resistance of the coated panels. Phosphated panels showed diminished corrosion resistance after exposure to these vibrations in water and water-based cleaners, but were not affected after exposure to ultrasonics when trichloroethylene was used as the medium. Phosphate-coated panels ultrasonically cleaned and then treated with supplementary oil exhibited relatively the same corrosion resistance as oiled phosphated panels not exposed to ultrasonic vibrations. Test procedure is given and results are discussed.
