1, kev ntxhov siab ua ntej plating qhov siab tshaj plaws tensile lub zog siab tshaj 1034Mpa qhov tseem ceeb thiab qhov tseem ceeb ua ntej plating yuav tsum nyob ntawm 200 ± 10 ℃ kev ntxhov siab nyem rau ntau tshaj 1 teev, carburizing lossis nto quenching qhov chaw yuav tsum nyob ntawm 140 ± 10 ℃ kev ntxhov siab nyem rau ntau tshaj 5 teev.
2. Tus neeg saib xyuas siv los ntxuav yuav tsum tsis muaj kev cuam tshuam rau lub zog ntawm cov txheej txheej thiab tsis muaj corrosion ntawm matrix.
3. Acid activation acid activation tov yuav tsum muaj peev xwm tshem tawm cov khoom siv corrosion thiab oxide zaj duab xis (daim tawv nqaij) ntawm qhov chaw ntawm qhov chaw, tsis muaj corrosion ntau dhau ntawm matrix.
4,galvanizedtuaj yeem siv zincate galvanized lossis chloride galvanized txheej txheem, yuav tsum siv cov khoom siv tsim nyog kom tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem txheej txheem no.
5, tom qab lub teeb plating yuav tsum tau nqa tawm kev kho lub teeb.
6, passivation kom tshem tawm hydrogen qhov chaw yuav tsum passivation tom qab tshem tawm ntawm hydrogen, passivation ua ntej daim ntawv thov ntawm 1% H2SO4 los yog 1% hydrochloric acid ua kom 5 ~ 15s.Passivation yuav tsum tau kho nrog cov xim chromate tshwj tsis yog tias tau teev tseg hauv cov duab kos duab.
