EFFECT OF METAL HARDNESS AND SURFACE FINISH UPON FRETTING CORROSION

Abstract

The fretting damage to each of two different surface finishes on each of two degrees of hardness of test specimens of the same carbon steel was determined. Five greases of nearly identical composition and physical characteristics were used, thus conceivably nullifying any effect due to these grease properties. If the hardness of the specimens was the same, the smoother finish suffered the most fretting damage in all but one case. When the effects of surface finish was considered it was observed that for the smoother finish the harder material fretted more, but for the coarser finish the softer material was affected most. This seeming contradiction has not been positively explained, but it is hoped that future work will provide information on which an explanation can be based.
