Umqulu omkhulu owenziwe ngocingo kukusetyenziswa kocingo lwentsimbi yekhabhoni ephantsi, emva kokwenza umzobo, ukususwa komhlwa, ubushushu obuphezulu be-annealing, ukupholisa kunye nezinye iinkqubo, ekusebenziseni kubanzi ngakumbi.Iqondo lobushushu bocingo olukhulu lolwelo olufakwe kwi-electroplating kufuneka lulawuleke kwi-30 ukuya kuma-50 ℃.Ngenxa yokuba iiyoni zekloridi kwindawo yokuhlambela ziyonakalisa kakhulu, izifudumezi zeglasi zequartz zisetyenziswa ngokubanzi.
Isetyenziswa ngokubanzi ekusebenzeni, ucingo lwentsimbi lunomonakalo othile, irusi elula kunye ne-corrosion, ngoko ke sinokusebenzisa indlela ye-galvanized ukuthintela ukubola kwemveliso.Ngokudibeneyo ukongeza kule ndlela, iindlela zonyango ezisetyenziswa ngokuqhelekileyo ngesinyithi kunye nonyango lwe-phosphating, unyango lwe-oxidation, njl. Unyango lwe-Metal phosphating: isinyithi kunye neemveliso zentsimbi ukususa ioli, i-rust, ibe yinto ethile yesisombululo setyuwa, unokwenza umaleko. yefilimu yetyuwa enyibilikayo emanzini kumphezulu wesinyithi, le nkqubo ibizwa ngokuba yi-phosphating treatment.
Umqulu omkhulu owenziwe ngamazi efilim yephosphating emnyama emnyama ukuya kwengwevu, ubukhulu buqhele ukuba yi-5-20μm, inokumelana nokugqwala okungcono emoyeni.I-Membrane sisakhiwo se-microporous, isakhono esinamandla sokupeyinta, esifana nokusetyenziswa njengepeyinti esezantsi, ukuxhathisa ukubola kunokuqhubela phambili.Unyango lwe-Metal oxidation: Yongeza iimveliso zentsimbi kwi-NaOH kunye ne-NaNO2 isisombululo esixubileyo, unyango lokufudumeza, umphezulu unokwenza umaleko wobunzima obumalunga ne-0.5-1.5μm ifilimu ye-blue oxide, ukuze ufikelele injongo yokuthintela ukubola kwentsimbi, le nkqubo ibizwa ngokuba unyango oluluhlaza, ekubhekiselwa kulo njengeblue.
Le filimu ye-oxide ine-elasticity enkulu kunye ne-lubricity, ayichaphazeli ukuchaneka kwamalungu.Ke ngoko, iinxalenye zezixhobo ezichanekileyo kunye nezixhobo ze-optical, intsimbi yasentwasahlobo, ishidi letsimbi elincinci, ucingo olucolekileyo lwensimbi kunye nokunye ngokuqhelekileyo unyango lwe-bluing.Unyango olusetyenziswa ngokuqhelekileyo lwegalvanizing yocingo olukhulu oluyintsimbi lulingana nokwenza umaleko okhuselayo kumphezulu wocingo lwentsimbi.Iindlela ezisetyenziswa ngokuqhelekileyo yidip galvanizing, ihot spray plating, vacuum plating njalo njalo.Iindlela ezahlukeneyo zineempawu ezihambelanayo.
