Description

Corrosion due to electrochemical reaction processes is a widespread concern costing the world upwards of $1 trillion each year. Most corrosion in wet or humid environments removes material from a structure and could compromise the stability and functionality of the original design. Corrosion modeling in both space and time allows one to predict the extended effects of electrochemical corrosion, and to optimize corrosion protection systems.

In this talk, electrochemical corrosion mechanisms will be reviewed, such as galvanic, pitting, and crevice corrosion. Multiphysics modeling challenges of corrosion processes, that involve electrochemistry analysis, structural mechanics, transport of chemistry species and fluid flow will be discussed. Case studies include spatial and/or temporal simulation of sacrificial anodes, Impressed Cathodic Current Protection (ICCP), anodic protection, stress corrosion in underground pipelines, and the effect of stray currents, utilizing either a finite element method (FEM) or a boundary element method (BEM) within COMSOL Multiphysics software suite.
