電解研磨の原理
Principles of Electropolishing.
溶液中に研磨対象物を入れて電流を流す事により、凸面が優先的に溶解し表面を平準化＝【研磨】します。
研磨対象を＋（プラス）極に接続し、対極板を－（マイナス）極に接続します。
NiTiの電解研磨においては複雑で小さな形を均一に研磨する事が難しく専門的な知識を使い研磨を行っています。
By placing the object to be polished in the solution and passing an electric current through it, convex surfaces are preferentially dissolved and the surface is leveled = [polished].
The object to be polished is connected to the + (positive) pole, and the counter plate is connected to the - (negative) pole.
In electrolytic polishing of NiTi, it is difficult to uniformly polish complex and small shapes, and polishing is performed using specialized knowledge.
