Holistic model for atmospheric corrosion Part 1 - Theoretical framework for production,transportation and deposition of marine salts

Abstract

This paper discusses the limitations of parametric modelling of corrosion and presents the case that accurate and flexible models of atmospheric corrosion require an ‘holistic’ approach. In such an approach, the processes controlling corrosion across a wide range of physical scales are modelled. These models are based as much as possible on the processes controlling the phenomena under consideration. Being fundamentally based, these models can be extended outside the data sets from which they are derived. This is the first of a series of papers outlining the use of this approach to predict corrosion in marine environments. It will consider the theoretical formulations required to model the production, transport and deposition of marine salts. It will present some predictions from these formulations and it will discuss the implications to corrosion of this theoretical understanding. Later papers will present the incorporation of these models into an information system and the validation of these models against data.
