Abstract
Corrosion behaviour of SS 316, Ni-based alloy 600, and Titanium alloy TA10 in four environments under 450 oC and 26 MPa for 60 h was studied in this work by corrosion rate, surface morphologies and EDS analysis. SS 316 suffered the most serious corrosion with many oxides and cracks formation when corrosive ions exist. Co-existence of Cl and PO4 helps inhibit corrosion of alloy 600. TA10 had the lowest corrosion rate and smallest oxide thickness, suggesting its excellent stability when exposed to harsh environments.
