英文摘要	The corrosion behaviour of Ti alloy TA8-1, Cu alloy B19 and Cu are studied under simulated early deep geological conditions of Beishan, China. In the short-term experiment, the influence of temperature on the corrosion properties of the studied materials is investigated by electrochemical impedance spectroscopy (EIS), potentiodynamic polarisation and cyclic polarisation. In the long-term immersion tests, the evolution of corrosion behaviour is investigated by EIS, in combination with SEM, XPS and Raman analysis. The results show that Ti alloy TA8-1 has the minimum corrosion current density (10(-7) A cm(-2)) and low pitting susceptibility, attributed to the formation of a thin passive film. Cu has the relatively high corrosion current density (similar to 10(-5) A cm(-2)) and low pitting susceptibility. The corrosion resistance of the Cu2O/Cu-2(OH)(3)Cl deposit layer is maintained during the two-month immersion test at 50 degrees C. Severe localised corrosion occurs on the surface of B19 and the corrosion resistance deteriorates obviously during the immersion test.
