prof V.S Muralidharan

I wrote a paper on " origin of corrosion potentials "in BULLETIN OF ELECTROCHEMISTRY , a journal came from CECRI( CENTRAL ELECTROCHEMICAL RESEARCH INSTITUTE KARAIKUDI -6 INDIA

you can ask for reprints from the librarian CECRI KARAIKUDI

OCP becoming noble is an indication of passivity ; that is all

you have to measure the film using ellipsometry or can calculate using CV

please see the papers by M.SATO emeritus professor JAPAN who discussed the subject with me when he came to India
