An Electrochemical Tungsten Surface Was Treated for

An electrochemical solution for surface treatment of tungsten carbide, which include sodium carbonate, sodium citrate and water, the ratio of parts by weight: 15-20 of sodium carbonate, sodium citrate, 5-10, 70-80 water. Advantages of the present invention are: the human body without harm, low non-toxic, environmentally friendly, cost, can significantly improve the efficiency of tungsten retreat. The solution adopted for the electrochemical back corrugating roller, tungsten carbide layer can be drained away at the surface of about 4 to 6 hours.

An electrochemical solution treatment of the tungsten carbide surface, characterized in that it comprises sodium carbonate, sodium citrate and water, the parts by weight ratio of: sodium carbonate, sodium citrate 15-20 70 Water 5-10 -8`0.
