A basic polishing solution consisting of perchloric acid and methanol was optimized by adding citric acid and glycerol, and different kind of polishing solution was used for electropolishing of titanium nickel alloy wires. The surface morphology, corrosion resistance, and blood compatibility of untreated and polished wires were compared and studied. The results show that addition of citric acid and glycerol has a significant effect in corrosion inhibition and increases the controllability of the polishing process. With the optimized polishing solution, the surface of electropolished titanium nickel wire becomes flatter, with average roughness declined from 161.3 nm to 15.6 nm. The self-corrosion potential increases from -0.167 V to 0.045 V. The dissolved nickel content of phosphate buffer solution becomes lower, indicating the higher corrosion resistance. The hemolysis rate declines from 2.333% to 0.333%, and the number of adhesive platelet significantly decreases, thus the blood compatibility is enhanced.

添加柠檬酸和甘油对高氯酸-甲醇基础抛光液进行优化,用不同抛光液对钛镍合金丝材进行电解抛光,对比研究了抛光前后丝材的表面形貌、抗腐蚀性和血液相容性。结果表明,添加柠檬酸和甘油后抛光液缓蚀效果明显,增加了抛光过程的可控性;与抛光前相比,优化后抛光液电解抛光的钛镍丝材表面平整,平均粗糙度从161.3 nm降至15.6 nm,自腐蚀电位从-0.167 V升至0.045 V,磷酸盐缓冲液中镍溶出量更低,抗腐蚀性提高,溶血率从2.333%降至0.333%,血小板黏附数量明显减少,血液相容性得到改善。

添加柠檬酸和甘油对高氯酸-甲醇基础抛光液进行优化,用不同抛光液对钛镍合金丝材进行电解抛光,对比研究了抛光前后丝材的表面形貌、抗腐蚀性和血液相容性。结果表明,添加柠檬酸和甘油后抛光液缓蚀效果明显,增加了抛光过程的可控性;与抛光前相比,优化后抛光液电解抛光的钛镍丝材表面平整,平均粗糙度从161.3 nm降至15.6 nm,自腐蚀电位从-0.167 V升至0.045 V,磷酸盐缓冲液中镍溶出量更低,抗腐蚀性提高,溶血率从2.333%降至0.333%,血小板黏附数量明显减少,血液相容性得到改善。

A basic polishing solution consisting of perchloric acid and methanol was optimized by adding citric acid and glycerol, and different kind of polishing solution was used for electropolishing of titanium nickel alloy wires. The surface morphology, corrosion resistance, and blood compatibility of untreated and polished wires were compared and studied. The results show that addition of citric acid and glycerol has a significant effect in corrosion inhibition and increases the controllability of the polishing process. With the optimized polishing solution, the surface of electropolished titanium nickel wire becomes flatter, with average roughness declined from 161.3 nm to 15.6 nm. The self-corrosion potential increases from -0.167 V to 0.045 V. The dissolved nickel content of phosphate buffer solution becomes lower, indicating the higher corrosion resistance. The hemolysis rate declines from 2.333% to 0.333%, and the number of adhesive platelet significantly decreases, thus the blood compatibility is enhanced.
