Stress Corrosion Cracking of Mild Steel in a Phosphate Solution

Stress corrosion cracking of mild steel in a phosphate environment has been investigated at both room temperature. and 100°c: Prediction of this solution as a cracking medium was made on the basis of results obtamed from high and low sweep rate potentiodynamic polarisation curves.X-ray analysis indicates that at 100°c the stress corrosion behaviour may be related to the type of phosphate film formed at the metal surface.
