title: In-situ spectroelectrochemical characterization of the electrochemical growth and breakdown of a lead dodecanoate coating on a lead substrate.
abstract: This paper concerns a time lapse spectroelectrochemical study of the growth of lead dodecanoate layers on a lead substrate in an aqueous solution using cyclic voltammetry. In-situ synchrotron radiation X-ray diffraction measurements were carried out on station BM26A (DUBBLE) at the European Synchrotron Radiation Facility (ESRF) in France. The diffraction pattern images were taken using a two-dimensional Mar CCD camera. After deposition of the coating, a spectroelectrochemical study of a linear sweep voltammetry experiment using an acetic acid electrolyte, simulating 'active' lead corrosion, was carried out on both a bare and lead dodecanoate coated sample. The results show that the coating inhibits the formation of new lead corrosion products.
