不銹鋼(gang)電(dian)(dian)解(jie)拋(pao)光(guang)是(shi)一種利用電(dian)(dian)解(jie)原理(li)對不銹鋼(gang)表(biao)面(mian)進(jin)行處理(li)的(de)工藝。首先，將(jiang)待拋(pao)光(guang)的(de)不銹鋼(gang)零件作為陽極(ji)，浸入含有、硫(liu)酸等電(dian)(dian)解(jie)液(ye)中(zhong)，同時(shi)陰極(ji)是(shi)直(zhi)流電(dian)(dian)源的(de)負極(ji)。電(dian)(dian)流通過(guo)(guo)電(dian)(dian)解(jie)液(ye)時(shi)，陽極(ji)的(de)金屬溶解(jie)，形(xing)成離子(zi)，這(zhe)些(xie)離子(zi)在陰極(ji)上(shang)沉積(ji)，使不銹鋼(gang)表(biao)面(mian)形(xing)成光(guang)滑的(de)鏡面(mian)效果。拋(pao)光(guang)過(guo)(guo)程(cheng)中(zhong)，還會(hui)(hui)添加(jia)適量的(de)添加(jia)劑(ji)如(ru)拋(pao)光(guang)劑(ji)和緩蝕劑(ji)，以控制電(dian)(dian)流效率和防止過(guo)(guo)腐蝕。配方會(hui)(hui)根(gen)據(ju)不同的(de)不銹鋼(gang)類型和拋(pao)光(guang)要求進(jin)行調整，常見的(de)包括、硫(liu)酸、鉻酸、磷(lin)酸等，比例控制至關重(zhong)要。整個(ge)過(guo)(guo)程(cheng)需要嚴格(ge)控制溫度(du)、電(dian)(dian)流密度(du)和時(shi)間(jian)，以達(da)到理(li)想(xiang)的(de)拋(pao)光(guang)效果。
