Khoom Description
Nyob rau hauv magnesium alloys, muaj hlau, npib tsib xee, tooj liab, los yog cobalt muaj zog activates corrosion. Nyob rau hauv ntau tshaj li cov kab, cov hlau no precipitate li intermetallic tebchaw, thiab cov precipitate locales ua hauj lwm raws li active cathodic qhov chaw uas txo cov dej, ua rau poob ntawm magnesium. Tswj kom muaj nuj nqis ntawm cov hlau no txhim kho corrosion kuj. Txaus manganese kov yeej cov teebmeem corrosive ntawm hlau. Qhov no yuav tsum muaj kev tswj xyuas meej txog kev muaj pes tsawg leeg, nce nqi. Ntxiv cov tshuaj lom cathodic captures atomic hydrogen hauv cov qauv ntawm cov hlau. Qhov no tiv thaiv kev tsim cov roj hydrogen dawb, qhov tseem ceeb ntawm cov txheej txheem tshuaj corrosive. Qhov sib ntxiv ntawm kwv yees li ib ntawm peb puas qhov chaw arsenic txo qhov corrosion ntawm magnesium nyob rau hauv cov ntsev tov los ntawm ib qho ntawm ze li kaum.
