摘要
在室温下采用含1 mol/L NaCl和1%(体积分数)蒸馏水的乙二醇溶液对钛合金管进行电化学抛光。测试了在不同极间距下抛光时电流密度随电压的变化,得到较佳的抛光电压和极间距分别为17 V和20 mm。在该条件下电化学抛光后,镍钛合金管表面形成TiO2薄膜,整体光滑、均匀,表面粗糙度为70.5 nm。
The electrochemical polishing of nickel-titanium alloy tube was carried out in an ethylene glycol solution containing 1 mol/L of NaCl and 1vol.%of distilled water at room temperature.The variation of current density with voltage during the process of polishing at different inter-electrode distances were studied.The optimal voltage and interelectrode distance were determined to be 17 V and 20 mm,respectively.After electrochemical polishing under the optimized conditions,a TiO2 thin film was formed on the smooth and uniform surface of nickel-titanium alloy tube with a roughness of 70.5 nm.
