STUDY ON LOCALIZED CORROSION OF METAL UNDER OIL FILM
油膜下局部腐蚀的探讨

The electrochemical parameters and their distribution of oil film were surveyed directly and the corrosion conditions of metal under oil film was studied by measuring the potential and corrosion current of each wire using wire beam electrode. The results showed that there was corrosion cell beneath oil film where corrosion occurred locally, the metal in cathode area was protected and that in anode area was corroded.
