Tungsten-removing Treatment Method of Tungsten Carbide Work Piece

The invention relates to the technical field of tungsten-removing treatment methods and provides a tungsten-removing treatment method of a tungsten carbide work piece, which has no damages on human bodies and no toxin, and is environmental friendly and low in cost. The tungsten-removing treatment method comprises the following technical steps of: washing the tungsten carbide work, clamping, preparing electrolyte, removing a coating and washing.

The withdrawal of tungsten carbide workpiece processing method characterized by comprising the following process steps: (1) tungsten carbide workpiece cleaning: first with cleaning liquid carbide workpiece, the workpiece surface to remove oil tungsten carbide, tungsten carbide with water Rinse the workpiece; (2) clamping: tungsten carbide workpiece fixture, so that the tungsten carbide is rotatably secured to the workpiece at both ends of the cell; (3) the preparation of the cell electrolyte: Add in an electrolytic cell in a ton water and then added to 50kg of Na2CO3UOkg potassium sodium tartrate and stirred and dissolved; (4) removal of the coating: tungsten carbide workpiece as anode and a stainless steel plate as the cathode, turn on the power, so that the workpiece is rotated in the electrolytic tank tungsten carbide, full contact with the electrolyte, an electrolytic reaction occurs, the current density at (200-300) * Wu DL (A ^ m2), the electrolytic solution controlled at 10-13 PH, temperature controlled at 20-80 ° C, the electrolysis reaction time is 12 hours; (5) Cleaning: Remove tungsten carbide workpiece after electrolysis, its surface with water to rinse.
