Abstract
In previous works, authors have noted that corrosive wear was mainly determined by electrochemical dissolution, where the wear volume was equivalent to the corrosion volume calculated according to Faraday's law with the anodic current density obtained by potential pulse method. However, the corrosion volume has not actually been measured yet for the confirmation. In this paper, a wear test using SUS304 (type 304) stainless steel in Na2SO4 solution was carried out to evaluate the corrosion volume in terms of dissolved iron determined by absorption spectroscopy as well as the calculation by Faraday 's law. As a result, both corrosion volumes were almost the same as the wear volume. Therefore, it was confirmed that the estimation of the corrosion volume by the potential pulse method was reasonable and the electrochemical factor was significant in the corrosive wear. Presented as a Society of Tribologists and Lubrication Engineers paper at the World Tribology Congress in London, United Kingdom, September 8–12, 1997
