Corrosion Chemistry. Faraday Discussion

Description

Introduction

Over the last decade or so, there has been immense progress in the development of tools, both experimental and theoretical, for probing the solid/fluid interface at the nanoscale. These advances open the way towards mechanistic understanding, and potentially prediction, of chemical processes occurring at this interface.  Amongst the fields beginning to benefit from such effort is corrosion science, which is primarily concerned with degradation of metallic materials immersed in either liquid or gaseous environments, and control thereof. Corrosion science does not always attract the plaudits of other more fashionable subjects, but is nevertheless of huge strategic importance. This statement is increasingly true as we move towards a world where every atom counts, e.g. in maintaining the performance of nano-devices, as well for ensuring sustainability through optimum use of natural resources.

Aims

The aim of this Faraday Discussion is to bring together experimentalists and theoreticians concerned with understanding at the nanoscale interfacial chemical processes relevant to corrosion and its control.

Format

The Faraday Division have been organising high impact Faraday Discussions in rapidly developing areas of physical chemistry and its interfaces with other scientific disciplines for over 100 years.

Faraday Discussions have a special format where research papers written by the speakers are distributed to all participants before the meeting, and most of the meeting is devoted to discussing the papers. Everyone contributes to the discussion - including presenting their own relevant research. The research papers and a record of the discussion are published in the journal Faraday Discussions.

Themes

  • Solid/Fluid Interface

In this session, studies concerned with nanoscale elucidation of the structure and fundamental chemical processes (e.g. ion adsorption) at solid/fluid interfaces will be discussed. Particular attention will focus on the solid/aqueous solution interface, as it is of central importance to corrosion. Contributions will cover experimental work, with particular emphasis on in situ studies using state-of-the-art probes, and theoretical modeling.

  • Corrosion Scales and Passive Films

Substrate adhered corrosion scales and passive films, which can both significantly affect corrosion (e.g. a passive film can reduce corrosion to a negligible rate), will be the topics of discussion here. Experimental/theoretical studies of both engineering and model (e.g. single crystal) substrates will be presented. Relationships between the composition-structure-chemistry-corrosion resistance of the scales/films will be addressed, together with insight into processes governing their initiation and growth, including the impact of environmental conditions

  • Localised Corrosion

Spatially confined corrosion phenomena (e.g. pitting), which can lead to rapid failure of otherwise corrosion resistant substrates, will be of concern in this session. Studies aiming to understand at the nanoscale the combined influences of substrate microstructure/geometry, mechanical distortion, and fluid chemistry on local corrosion initiation/progression will be presented. Modeling of these processes will also feature, as prediction of their occurrence is of huge technological concern

  • Corrosion Control

To complement the above sessions, this final session will address nanoscale understanding of corrosion control methods. In particular, it will be concerned with approaches where chemistry plays a key role, namely coatings, paints, and corrosion inhibitors. Topics of discussion will centre on those critical to gain mechanistic insight into corrosion resistance performance, including substrate bonding, structure/morphology, interfacial transport, and degradation mechanisms.
