Abstract
WE have been interested in the nature and amount of films formed on metals during and immediately after cleaning by abrasion, and have made measurements of the thickness of such films using a modification of the electrolytic method of Evans and Miley1. We find that films of substantially the same thickness, giving similar cathode potential time curves at constant current, are present on freshly abraded copper whether the abrasion is carried out in air or under benzene. A somewhat thinner film was found when an abrasive wet with water was used. The results are summarized in the accompanying table, the figures in the third and fourth columns representing the means of at least three determinations for experiments 1–3 and of two determinations for experiments 4 and 5. Typical curves are given in the accompanying figure.
