METHOD FOR IMPROVING SURFACE ROUGHNESS DURING ELECTRO-POLISHING

摘要

A surface is electropolished using a stream of electrolyte. A nozzle is used to apply the stream of electrolyte to the surface. The nozzle has an insulator wall and a partial electrode. The insulator wall and the partial electrode form a flow channel for the stream of electrolyte. The stream of electrolyte contacts the insulator wall and the partial electrode when the stream of electrolyte flows through the flow channel formed by the insulator wall and the partial electrode. The insulator wall is less electrically conductive than the partial electrode. A power supply is connected to the partial electrode. The power supply is configured to apply a charge to the stream of electrolyte through the partial electrode when the stream of electrolyte flows through the flow channel formed by the insulator wall and the partial electrode.
