Phase-field modeling for pH-dependent general and pitting corrosion of iron

Scientific Reports, 2018
This study proposes a new phase-field (PF) model to simulate the pH-dependent corrosion of iron. The model is formulated based on Bockris’s iron dissolution mechanism to describe the pH dependence of the corrosion rate.

Development of a Method for Corrosion Fatigue Life Prediction of Structurally Loaded Bearing Steels

, 2001
In this study a simplified method to predict corrosion fatigue properties for the Cr-alloyed bearing steel 100CrMnMo8 is proposed. With this method corrosion pits are assumed to act as defects, which could initiate fatigue cracks.
