Abstract
The surface modification for SUS316L stainless steel was carried out by electroplating Rh, ion beam assisted deposition Ta2O5 and sol-gel-derived TiO2. In Tyrode's stimulated body fluid, the surface modified samples had been investigated with electrochemical techniques. The results indicated that the electrochemical stability and dissolution were improved significantly after surface modification. Moreover, as to ion beam assisted deposition Ta2O5 and Sol-gel-derived TiO2 film, the metal's d orbit electron holes filled up by the oxygen electrons made against the adsorption of hydrogen. Thus the cathode process, which is controlled by the hydrogen reduction,was held back. X-ray diffraction analysis of SUS316L stainless steel after surface modification revealed that each method fored the uniform and compact film on SUS316L stainless steel. These films also prevented dissolving of elements and improved the electrochemical behavior of the SUS316L stainless steel.
