微弧氧化技術原理

將工(gong)(gong)件（鋁、鎂、鈦(tai)、鋯及其合金）和(he)不銹鋼（或石墨(mo)）板置于電(dian)(dian)(dian)(dian)解質水(shui)溶(rong)液(ye)中，工(gong)(gong)件接電(dian)(dian)(dian)(dian)源(yuan)(yuan)正極，不銹鋼（或石墨(mo)）板接電(dian)(dian)(dian)(dian)源(yuan)(yuan)負極，電(dian)(dian)(dian)(dian)源(yuan)(yuan)接通(tong)后工(gong)(gong)件表面(mian)發生(sheng)(sheng)陽極鈍(dun)化(hua)生(sheng)(sheng)成(cheng)高阻kang氧(yang)(yang)化(hua)膜，隨(sui)著(zhu)氧(yang)(yang)化(hua)膜增(zeng)厚以及外(wai)加(jia)電(dian)(dian)(dian)(dian)壓(ya)的(de)不斷增(zeng)加(jia)，高電(dian)(dian)(dian)(dian)場強度使得(de)氧(yang)(yang)化(hua)膜內部(bu)及表面(mian)電(dian)(dian)(dian)(dian)荷積累變得(de)嚴(yan)重(zhong)。固體(ti)絕緣材料(liao)中空間電(dian)(dian)(dian)(dian)荷的(de)存在(zai)(zai)使得(de)原來的(de)電(dian)(dian)(dian)(dian)場發生(sheng)(sheng)畸變，使局部(bu)電(dian)(dian)(dian)(dian)場加(jia)強，微(wei)弧(hu)(hu)氧(yang)(yang)化(hua)生(sheng)(sheng)產(chan)線多少錢(qian)，導致氧(yang)(yang)化(hua)膜擊穿(chuan)，微(wei)弧(hu)(hu)氧(yang)(yang)化(hua)生(sheng)(sheng)產(chan)線批(pi)發，產(chan)生(sheng)(sheng)火(huo)花放電(dian)(dian)(dian)(dian)。當氧(yang)(yang)化(hua)膜被(bei)擊穿(chuan)后，就會形成(cheng)基體(ti)金屬離(li)(li)子(zi)和(he)溶(rong)液(ye)中活性氧(yang)(yang)離(li)(li)子(zi)等物質擴(kuo)散轉移(yi)的(de)通(tong)道(dao)，微(wei)弧(hu)(hu)氧(yang)(yang)化(hua)生(sheng)(sheng)產(chan)線供應，基體(ti)金屬離(li)(li)子(zi)和(he)氧(yang)(yang)離(li)(li)子(zi)，在(zai)(zai)電(dian)(dian)(dian)(dian)化(hua)學、熱化(hua)學和(he)等離(li)(li)子(zi)體(ti)化(hua)學的(de)共同作用下，生(sheng)(sheng)成(cheng)氧(yang)(yang)化(hua)物陶瓷。
