[Effect of fluoride ion on corrosion of two dental titanium alloys].


OBJECTIVE To investigate the effect of fluoride concentration on the corrosion behavior of Ti-12Zr alloy and Ti-6Al-4V alloy in a simulated oral environment. METHODS Each specimen was put into the acidic artificial saliva (pH = 4.0) with different NaF concentration (0%, 0.05%, 0.1%, 0.2%) and electrochemical experiment was carried out. Then the surface… (More)
