Abstract

A method for predicting SCC performance is described involving the corrosion based design approach (CBDA) and the locations for analysis matrix (LAM). This method provides bases for considering all the factors that contribute to corrosion-related failure in an orderly framework. The CBDA includes the steps of environmental definition, material definition, mode definition, superposition, failure definition, statistical definition, accelerated testing, prediction, monitoring and feedback, and fix. The LAM is a matrix that applies to a specific subcomponent and provides a framework for explicit actions for each mode of corrosion at each location where conditions are the most aggressive.
