A ) Recent Advances in Surface Analytical Techniques and Applications to Corrosion Research
organised by V. Maurice, A. Galtayries and P. Marcus
In order to understand and control the reactivity of metal and alloys at various stages of corrosion processes, it is essential to characterize their surface from the chemical and structural points of view. The continuing development of surface analytical techniques over the 4 last decades have allowed major progresses in the knowledge of corrosion-related surface modifications at liquid/solid and gas/solid interfaces, and both in ex situ and in situ conditions. The objective of the Workshop will be to exchange and discuss information on the most recent advances of surface analysis (including the various surface spectroscopies and surface imaging techniques) and their applications to all areas of corrosion research. Contributions on both technical advances and/or application developments are welcome.

B) Biomolecules and Biofilms on Surfaces: Impact on the Corrosion Resistance
organised by B. Tribollet, I. Frateur and R. Gubner
Biofilms can significantly affect the interfacial chemistry between the colonized material and the fluid, and influence the kinetics of corrosion processes. The adsorption of biomolecules on metals and alloys, the influence of bio-adsorption on the surface layer composition and structure, and the effect of microbial adhesion on the electrochemical behaviour of metallic materials will be considered. Papers on appropriate methods to characterise biofilms, their interactions with material surfaces, environments and biocides are also welcome.

C) Simulation, Modelling and Life Prediction
organised by R. Oltra, R.A. Cottis, M. Vankeerberghen and P. Marcus
Corrosion modelling has made considerable progress in the recent past in terms of both the fidelity of the models and the range of size scales. This is in part because new tools have become available (molecular simulation, FEM packages, probabilistic tools). This workshop will aim at presenting and discussing the state-of-the-art in corrosion modelling and simulation. Papers are solicited on all aspects of corrosion simulation, modelling and life prediction, including:
- atomistic simulation of the initial stage of the interfacial reactions (passivation, selective dissolution, coating degradation, localized corrosion)
- modelling of mass transfer control on the local chemistry (and/or electrochemistry),
- modelling of the effect of mechanical stresses and deformation,
- modelling of morphological degradation.

D) Corrosion of Archaeological and Heritage Artefacts: from Mechanistic Studies to Conservation Strategies
organised by P. Dillmann and G. Béranger
The understanding of corrosion mechanisms that occur on archaeological/heritage materials and artefacts is a challenge in different fields of research. It is a crucial step for setting up diagnosis methodologies to evaluate the conservation state of heritage buildings and artefacts. This diagnosis leads to general conservation strategies that could imply different
actions and treatments, from the simple measurement of the environmental conditions in a museum to the complete change of metallic pieces in a monument. Moreover, the study
of complex corrosion systems developed on ancient artefacts, allowing specific parametric measurements (reactivity, porosity…) and tests of mechanism hypotheses, helps the modelling
of the very long term corrosion behaviour for engineering materials used in the future as, for example, in the specific context of long term waste storage. The aim of this session, 5 years after the one that was held in Nice on the same subject, is to give a general overview of the hottest topics in this field, and to point out significant advances since 2004. It concerns all materials (metals, stone, glasses, etc) that are encountered in heritage context and are submitted to long term alteration/corrosion.

E) Workshop on Bio-Tribocorrosion
organised by P. Ponthiaux and J.-P. Celis
The objective of this workshop, the third one after Nice (2004) and Freiburg (2007), organised in collaboration with COST 533 Biotribology & Network for Industrial Wear Prevention (EUREKAENIWEP), is to exchange and discuss scientific and technological information leading to a growing understanding of the mechanisms governing surface degradation by tribocorrosion, but also of the possible self-healing aspects linked to tribocorrosion. Quite diverse industrial fields such as power plants, transportation, aeronautics, microelectronics and bio-engineering will be covered. Contributions related to industrial field experience as well as multi-scale analyses and multi-disciplinar approaches at laboratory scale are welcome. Contributions related to progress on testing and standardisation are also welcome.

F) Sea Water Fouling Control: Coatings, Biocides Treatments
organised by J.-P. Pautasso
In sea water, corrosion control, heat exchanger efficiency and hydrodynamic performances are closely dependent on fouling control (biofilm, microfouling, macrofouling). On one hand,
many owners are concerned by increasing the dry-docking intervals and the durability of their facilities in order to have higher operational availability combined to reduced running costs.
On the other hand, the worldwide pressure set by environment regulations limits the use of biocides, which could cause a critical reduction of performances. The objective of this workshop is to review the current situation and to predict possible future technological evolutions, through presentations dealing with R&D actions in progress, experimentation, standardization…
Two different applications will be considered:
- Antifouling coatings for underwater hull of ships,
- Biocide treatments for seawater piping systems applicable to the various metallic materials technologies in presence (steel, stainless steels, Ni base alloys, copper alloys...).

G) Corrosion Issues in Future High Temperature Nuclear Systems
organised by D. Féron, M. Schütze and R. Mizia
The importance of nuclear energy is increasing for sustainable development and particularly for the prevention of global warming and climate changes. New nuclear systems are under development to face these issues. These new nuclear systems are generally operating at higher temperatures and in very different media, which are often well-known for their aggressiveness (liquid metals, gas, molten salts, super critical water…). The reliable prediction of the corrosion behaviour of the selected materials for these new nuclear systems represents one of the greatest scientific and technical challenges. Clearly, the reliability and the viability of these predictions are of paramount importance in assuring the public that nuclear energy will play a key role in the future of energy production. With the goal of promoting scientific and technical exchanges, this workshop organised jointly by the "Corrosion by Hot Gases and Combustion Products" and "Nuclear Corrosion" EFC Working Parties and by the NACE's TEG 224X on Nuclear System Corrosion, will address the corrosion issues in the following future nuclear systems:
- Fusion technology reactors (ITER, DEMO),
- Hybrid systems (ADS),
- Generation IV systems: gas cooled reactors (HTR, VHTR, GFR), liquid metal reactors (LFR, SFR), molten salts reactor (MSR) and supercritical water reactor (SCWR).

H) Cathodic Protection of Steel in Concrete by Galvanic Anodes
organised by V. L'Hostis and G. Taché
Cathodic protection of steel in existing reinforced concrete structures by impressed current using a permanent current external source is a proven technique, with numerous applications. The use of galvanic anodes, without impressed current, is a more recent technique. In this system, current is supplied by the use of a dissimilar metal, coupled with the steel rebar. One application of sacrificial anode systems to repair patches is to provide cathodic protection to the parent concrete in the surrounding area. This is usually achieved simply by installation of an activated zinc anode within the repaired area during the repair process. These systems can include thermal sprayed pure zinc (or alloys), zinc adhesive anodes, zinc mesh anodes, cylindrical zinc anodes… The objective of this workshop is to exchange and discuss feedback experience on these techniques. Presentations of typical site installations, measurements and control are welcome.
