Abstract
ABSTRACTAn investigation of the ion beam mixing of Mo and Ta layers with 304 stainless steel and the potentiodynamic polarization behavior of the modified surfaces are described.Alternating thin layers (<100Å) of stainless steel (304) and either Mo or Ta were deposited by electron beam evaporation. Ion mixing was performed with 2 MeV Ni+ at a fluence of 5 × 1016cm−2. Examination of the mixed surfaces with TEN revealed characteristics of the amorphous phase and in some cases being embedded with crystalline regions for both Mo and Ta mixed stainless steel surfaces. The amorphous surfaces were tested for their corrosion behavior in 1M H2SO4 and O.1M NaCl solutions by the potentiodynamic polarization method. Significantly improved corrosion behavior were obtained for modified surfaces compared to unmodified stainless steel.
