Abstract
ABSTRACTThe article is an account of the development of a new technique to improve the surface properties of materials by ion beam bombardment combined effect of ion implantation and ion beam mixing.Ti+ ion beam has been used to mix the surface of Cr-deposited on to Fe or to implant Ti+ into the surface of Fe. By comparing the electrochemical properties, it has been shown that the corrosion resistance of Cr-deposited Fe surface mixed with Ti + ion beam is much better than that of Ti+ ion implanted Fe surface, the critical current density Ic and minimum anodic passive current density Im are decreased by one order of magnitude in deacrated 1M CH3 -COONa-CH3 COOH solution (pH 7.3, 25°C). AES and SIMS observation show Nhat the gombined effect of implantation and mixing has been really achieved.
