目前,国内电解加工夹具主要采用玻璃钢和不锈钢二种材料;由于璃玻钢材料吸力率高,热膨胀系数较大,耐磨性较差,经过电解液的冲刷、浸泡,产生起层现象,电阻率迅速降底,成为导体或半导体,又由于电解加工杂散电流的作用,通常不锈钢等金属材料在电解中都发生离子迁移,产生了严重蜂窝状腐蚀,一副新夹具经不长时间就产生腐
At present, the domestic electrolysis processing fixture mainly adopts two kinds of materials of glass fiber reinforced plastic and stainless steel. Because glass glass steel material has high suction rate, large thermal expansion coefficient and poor abrasion resistance, after electrolytic solution is washed and soaked, Quickly down to become a conductor or a semiconductor, but also due to the role of stray current electrolysis processing, usually stainless steel and other metal materials have occurred in the electrolysis ion migration, resulting in a serious honeycomb corrosion, a new fixture after a long time produce rot
