Topography, properties and corrosion resistance of glow-discharge nitrided layer produced on OT4-0 titanium alloy

摘要

The effects of heat nitnding of an OT4-0 titanium alloy (97.4 wt% Ti) sub-strate on its mechanical properties and electrochemical corrosion resistance are discussed. The potentiokinetic polarisation curves of the titanium alloy in initial state and titanium treated in a 1:1 vol. N_2/H_2 atmosphere (800°C) have been measured in acidified (pH = 2.7 and pH = 5.0) sulphate solutions.
