摘要
The aim of this study is to investigate the behaviour of new dental titanium alloys containing either Ta or Mo in Carter-Brugirard on artificial saliva, with and without fluoride ions, and to compare with the behaviour of Ti6Al7Nb alloy, which is used frequently in dentistry. The open circuit potential was measured and the 44 polarization resistance and corrosion currents were estimated from linear sweep voltametric analysis, The results have shown that Ti40Ta and Ti40Mo alloys have a good corrosion resistance in artificial saliva, acidified saliva (pH = 2.5) and fluoridated saliva (1000 ppm F on). We established that the corrosion of Ti6Al7Nb, Ti40Ta and NOW alloys is enhanced in fluoridated acidified saliva.
