AI Technical Summary
Existing electrochemical mechanical polishing processes suffer from problems such as excessive material removal from workpiece edges, low machining accuracy, and salt spray corrosion caused by liquid electrolytes.
Electrochemical grinding/electrochemical mechanical polishing is performed using a solid electrolyte gel. The solid electrolyte matrix, formed by agar, organophosphonic acid and abrasive, is used to generate and remove a passivation film through electrochemical reaction, thus avoiding the negative effects of liquid electrolyte.
It solves the problems of excessive material removal and salt spray corrosion at the workpiece edges, improves machining accuracy and surface quality, reduces costs and simplifies equipment, and is suitable for thin-walled curved workpieces.
