摘要
The oxidation of Al-implanted (implantation energy 40 keV, dose 10(16)-10(17) Al ions/cm2) AISI 321 stainless steel samples in air has been studied at temperatures between 450 and 650-degrees-C using the O-16(d,p)O-17 nuclear reaction. The determination of the distribution of the implanted Al atoms has been performed using the resonance at 992 keV of the Al-27(p,gamma)Si-28 nuclear reaction. The determined oxygen profiles indicate that the implantation of 5 x 10(16) and 10(17) Al ions/cm2 leads to an improvement of the oxidation resistance of the studied steel samples. The passivation/corrosion behaviour of the Al-implanted steel samples in 0.5M aqueous sulphuric acid solution has also been investigated electrochemically using potentiodynamic and cyclovoltammetric techniques. The passivation potential values and the repassivation moving to more positive values indicate an improvement of the corrosion resistance of the Al-implanted steel samples.
