本发明属于医疗器械表面处理技术领域，具体涉及一种电解抛光液、应用及电解抛光方法。本发明提供的可降解镁合金支架的电解抛光方法，包括如下步骤：S1：将待抛光的可降解镁合金支架采用无水乙醇进行清洗；S2：采用上述电解抛光液进行电解抛光，电解抛光分多次进行，每次电解抛光之后用无水乙醇清洗。本发明提供的电解抛光方法，打破传统方法中的结合化学抛光（酸洗）步骤，减少支架在化学试剂中腐蚀时间，减少对支架基体的微观结构的影响；在单次抛光后增加清洗，可有效控制表面氧化膜的产生，可抛光出表面光洁度、平整度良好镁合金支架；本发明提供的电解抛光方法工艺简单、易操作，成本低，且适用范围广，适用于目前所有的镁合金抛光。

The invention belongs to the technical field of the surface treatment of medical instruments, in particular to an electrolytic polishing solution, an application and an electrolysis polishing method. The invention provides an electrolytic polishing method for a degradable magnesium alloy bracket, comprising the following steps: S1: washing the degradable magnesium alloys bracket to be polished with anhydrous alcohol; S2: The electrolytic polishing solution is used for electrolytic polishing, and the electrolysis polishing is carried out several times, and then cleaned with anhydrous alcohol after each electrolytic polishing. The electrolytic polishing method provided by the invention breaks the combined chemical polishing (pickling) step in the traditional method, reduces the corrosion time of the bracket in the chemical reagent, and reduces the influence on the microstructure of a bracket substrate; Adding cleaning after single polishing can effectively control the generation of surface oxide film and polish the magnesium alloy support with good surface finish and flatness. The electrolytic polishing method provided by the invention has the advantages of simple process, easy operation, low cost and wide application range, and is suitable for all current magnesium alloy polishing.
