Electrochemical formation of self-organized porousstructures on metallic substrates in organic solvents and their application

在本工作中，我们研究了各种金属衬底在有机溶剂中多孔表面的电化学形成，并实现了不锈钢、镍基合金、钴铬合金和钛表面在含高氯酸盐离子的有机溶剂和钒在含硫酸和盐酸的有机溶剂中的多孔化。SEM观察和AFM分析表明，多孔结构的形貌与施加电压和持续时间等电化学条件有关。我们还发现，在模拟体液中，不锈钢表面的孔隙化可以提高细胞活性和抗腐蚀性

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
