| Research Abstract |
In the present work we have examined the electrochemical formation of porous surface on various metallic substrates in organic solvents and achieved the porosification of stainless steel, nickel-based alloys, cobalt chromium alloy and titanium surfaces in perchlorate ion containing organic solvents and vanadium in organic solvents containing sulfuric acid and hydrochloric acid. SEM observations and AFM analyses indicated that the morphology of porous structure depended on electrochemical conditions such as applied voltage and duration. Wealso found that the porosification of stainless steel surface can improve cell activity as well as corrosion resistance in a simulated body fluid
