| Abstract: | Amorphous Al(Ti),Al(Pd)alloy layers are prepared by ion beam mixing,andthe passivationof the layers in NaHCO3 aqueous solution(pH6.5)is investigated by means ofthree sweep polarization measurement,backscattering spectrometry and electronic microscopy.The corrosion rate for Ti35Al65 is twenty four times less than that for pure aluminum,but therate for Pd30Al70 is 44% greater .It implies that the electronchemical properties of alloy additivesremains a domminant factor to consider when ion beam techniques are used to develop corro-sion resistant alloy materials. |
