| Abstract: | TC16 titanium alloy was surface-modified by vacuum arc ion plating of TiN coating and micro-arc oxidation,while 18Ni steel was surface-modified by chemical oxidation.The level of galvanic corrosion,electrochemical impedance spectra and corroded morphology of the TC16 Ti alloy coupled with 18Ni steel was studied.Results indicate that there exists serious galvanic corrosion between TC16 Ti alloy and 18Ni steel,which can not be prevented by simply chemical oxidation treatment of 18Ni steel.By combining chemica... |
