Environmental Degradation of Metals and Alloys: Surface Analytical Approach, Mechanisms, and Modeling

    [abstract] The understanding of the interactions of metal and alloy surfaces with their environment is a key for the control of environmental degradation of materials and the development of metallic materials with extended and predictable life time.

    Chemical and electrochemical interactions at metal and alloy surfaces （adsorption, oxidation, corrosion） can be studied using advanced surface characterization techniques （surface spectroscopies and microscopies）， combined with electrochemical measurements. The corrosion mechanisms are then deduced from the data, and modeling and simulation methods provide further insight.

    The aim of this lecture is to review recent results obtained by combining advanced surface analytical techniques,Time-of-Flight Secondary Ions Mass Spectrometry （ToF-SIMS）， X-ray Photoelectron Spectroscopy （XPS）， Scanning Tunneling Microscopy （STM）， Scanning Tunneling Spectroscopy （STS）， Current Sensing Atomic Force Microscopy （CS-AFM）， with electrochemical techniques and modeling by Density Functional Theory （DFT）。

    The following issues will be addressed :

    -Corrosion at the nanoscale

    -Early oxidation/corrosion stages studied by advanced surface analytical techniques （XPS, ToF-SIMS）

    -DFT modeling of the reactivity of oxide films on metals

    -New oxide coatings for corrosion protection, deposited by ALD （Atomic Layer Deposition）

    The selected examples will cover various metals （Cu, Ni） and alloys （nickel-base alloys, stainless steels, aluminium alloys）， with applications in the aeronautic, oil and gas, and nuclear industries.

 Pr. Philippe Marcus

    Pr. Philippe Marcus is Director of Research at CNRS （Centre National de la Recherche Scientifique） and Head of the Research Group of Physical Chemistry of Surfaces of Institut de Recherche de Chimie Paris, Ecole Nationale Supérieure de Chimie de Paris, Chimie ParisTech, France. Dr Marcus received his Ph. D. （1979） in Physical Sciences from University Pierre and Marie Curie, Paris, France.

    His field of research is surface chemistry, surface electrochemistry, and corrosion science, with emphasis on the understanding of the structure and properties of metal and alloy surfaces.

    His research interests include the growth mechanisms and structure of oxide layers on metals and alloys in gaseous and aqueous environments, adsorption of inorganic, organic and biomolecules, the mechanisms of corrosion of metals and alloys at the nanoscale, passivity, passivity breakdown and localized corrosion, initial stages of high temperature oxidation, and the applications of advanced surface analytical methods such as X-ray Photoelectron Spectroscopy, Scanning Tunnelling Microscopy and Spectroscopy, and Time-of-Flight Secondary Ions Mass Spectrometry.

    Dr. Marcus has published over 400 papers in scientific journals, books and conference proceedings in the areas of corrosion science, surface chemistry and electrochemistry, surface analysis and materials science, plus three books “Corrosion Mechanisms in Theory and Practice”， “Analytical Methods in Corrosion Science and Engineering” and “Molecular Modeling of Corrosion Processes”。 He has given over 100 invited lectures at International Conferences. He serves or served on the editorial board of five major journals in Electrochemistry and Corrosion: Electrochimica Acta, Corrosion Science, Materials and Corrosion, Corrosion Engineering, Science, and Technology, and Corrosion Reviews. Pr. Marcus has received a number of awards and honors, including the 2005 Uhlig Award from the Electrochemical Society, the 2008 Whitney Award from NACE International, the Cavallaro Medal of the European Federation of Corrosion in 2008, the U.R. Evans Award of the UK Institute of Corrosion in 2010, the Lee Hsun Award of the Institute of Metals Research of the Chinese Academy of Sciences in 2012. He was the D.B. Robinson Distinguished Speaker of the University of Alberta, Edmonton, Canada in 2013. He received the European Corrosion Medal of EFC in 2015. He is an elected Fellow of the Electrochemical Society （2005） and of the International Society of Electrochemistry （2009）。

    Dr Marcus has organised or co-organised several international conferences. He was the Chairman of ECASIA （the European Conference on Applications of Surface and Interface Analysis, Avignon （F）， 2001）， EUROCORR （the European Corrosion Conference, Nice （F）， 2004） and Passivity-9 （the 9th International Conference on the Passivation of Metals and Semiconductors and the Properties of Thin Oxide Layers, Paris （F）， 2005）。 In 2006 he was the Chair of the Gordon Research Conference on Aqueous Corrosion （New London, NH, USA）。 He was the Chair of EUROCORR in 2009, and of EMNT （International Symposium on Electrochemical Micro and Nanosystems Technologies） in 2010. He is the Chairman of EUROCORR 2016.

    Dr. Marcus was President of the European Federation of Corrosion from 2008 to 2012. He was Chairman of the Electrochemical Materials Science Division of the International Society of Electrochemistry. He is currently Chairman of the EFC Working Party on Surface Science and Mechanisms of Corrosion and Protection, Chairman of the International Steering Committee for the European Conferences on Applications of Surface and Interface Analysis, Vice-President and Chairman of the Scientific and Technical Committee of CEFRACOR （French Corrosion Center）。

    Pr Marcus teaches Surface and Interface Chemistry, Surface and Interface Analysis, and Corrosion Science at Chimie ParisTech （ENSCP）， Polytech'Paris （University Pierre and Marie Curie）， and Master “Materials for Energy and Structure”。
