【Abstract】 B~+ implantations to pure iron, pure nickel and S. S. 316L and ion-mixing with Fe-Ti system are conducted at low temperature in a liquid nitrogen cooled chamber. Electron diffraction and polarization curves are made from the implanted and mixed surfaces. Results show that the electrochemical behavior of the ion-implanted and ion-mlxed surfaces prevails substantially over that of their matrixes. Multi-polarization curves of the same specimen are used to study the corrosion behavior of the ion-implanted and ion-mixed surfaces, it is found that corrosion resistance correlates well with concentration-depth profile of ions.更多还原
