一、前言化学抛光是继电解抛光之后出现的一种不用外加电流即可抛光金属表面的方法,其最大优点是:(1)不需要直流电源和特殊的接触夹具;(2)可以抛光形状复杂和尺寸悬殊的零件;(3)生产效率高。此外,与电抛光一样,化学抛光除提供化学和物理清洁的表面外,还可除去表面的机械损伤层,提供一个机械清洁度的表面,有利于提高零件的机械强度。 First, the foreword Chemical polishing is a kind of method that can polish the metal surface without electric current after the electrolytic polishing, the biggest advantage is: (1) Do not need the direct-current source and special contact fixture; (2) Can polish the shape Complex and size of the parts; (3) high production efficiency. In addition, electro-polishing, in addition to electro-chemical and physical cleaning, removes mechanical damage from the surface and provides a mechanically cleanable surface that improves the mechanical strength of the part.
