Research advances in environmental corrosivity mapping techniques

Abstract

Corrosion map is the most direct form of environmental corrosion, which can provide data support for the anti-corrosion design, construction and operation and maintenance of engineering equipment intuitively and quickly. The research advancements in environmental corrosivity mapping techniques are reviewed here. It delineates the atmospheric and soil corrosivity classification methods through qualitative and quantitative analysis. The merits and constraints of these classification methods and interpolation methods when applied to corrosion mapping are critically assessed.
