Electroplating surface treatment kusho

I-Electroplating yindlela lapho insimbi idonswa khona ku-electrolyte ngesenzo somsinga osetshenzisiwe bese ifakwa phezu kwento ukuze kutholwe isendlalelo sensimbi.

Okukhanyiswe:
I-Zinc igqwala kalula kuma-asidi, ama-alkali, nama-sulfide.I-zinc layer ngokuvamile ayidluliswanga.Ngemuva kokudlula kusixazululo sechromate, ifilimu ye-passivation eyakhiwe akulula ukusebenzisana nomoya omanzi, futhi nekhono lokulwa nokugqwala liyathuthukiswa kakhulu.Emoyeni owomile, i-zinc izinzile futhi akulula ukushintsha umbala.Emanzini nasemoyeni oswakeme, ihlangana ne-oxygen noma i-carbon dioxide yakhe i-oxide noma ifilimu ye-alkaline carbonic acid, engavimbela i-zinc ukuthi ingaqhubeki ne-oxidize futhi idlale indima yokuvikela.
Izinto ezisetshenziswayo: insimbi, izingxenye zensimbi

i-chrome:
I-Chromium izinzile kakhulu emkhathini oswakeme, i-alkali, i-nitric acid, i-sulfide, izixazululo ze-carbonate nama-asidi aphilayo, futhi incibilika kalula ku-hydrochloric acid kanye ne-sulfuric acid egxilile eshisayo.Ububi ukuthi iqinile, iyaphuka, futhi kulula ukuwa.I-chromium plating eqondile ebusweni bezingxenye zensimbi njengongqimba oluphikisana nokugqwala akulungile.Ngokuvamile, i-electroplating enezingqimba eziningi (okungukuthi i-copper plating → i-nickel → i-chromium) ingafinyelela injongo yokuvimbela nokugqwala.Njengamanje, isetshenziswa kabanzi ukuthuthukisa ukumelana nokugqoka kwezingxenye, usayizi wokulungisa, ukubonakaliswa kokukhanya nokuhlobisa.
Izinto ezisetshenziswayo: insimbi engavuthwanga, ithusi nengxubevange yethusi uziro ukuhlobisa nge-chrome plating, ukufakwa kwe-chrome okungagugi

I-Copper Plating:
I-Copper ayizinzile emoyeni, futhi ngesikhathi esifanayo, inamandla aphezulu futhi ayikwazi ukuvikela ezinye izinsimbi ekugqwaleni.Kodwa-ke, ithusi line-conductivity ephezulu kagesi, ungqimba lwe-copper plating luqinile futhi lulungile, luhlanganiswe ngokuqinile nensimbi eyisisekelo, futhi lunomsebenzi omuhle wokupholisha. enye i-electroplating, njengesendlalelo sokuvikela ukuvimbela i-carburization, nokunciphisa ukungqubuzana noma umhlobiso ekuthwaleni.

Izinto ezisetshenziswayo: insimbi emnyama, ithusi ne-copper alloy-plated nickel, ungqimba olungezansi olufakwe nge-chrome.

I-Nickel Plating:
I-nickel inokusimama okuhle kwamakhemikhali emkhathini nase-lye, futhi akulula ukushintsha umbala, kodwa incibilika kalula ku-nitric acid ehlanjululwayo.Kulula ukudlula ku-nitric acid egxilile, futhi ukonakala kwayo i-porosity.Ukuze unqobe lokhu kungalungile, kungasetshenziswa ungqimba lwensimbi olunezingqimba eziningi, futhi i-nickel iyingqimba ephakathi.Isendlalelo se-nickel plating sinokuqina okuphezulu, kulula ukupholishwa, sinokubonakala okuphezulu kokukhanya futhi singakhuphula ukubukeka nokumelana, futhi sinokumelana nokugqwala okuhle.
Izinto ezisetshenziswayo: zingafakwa phezu kwezinto ezihlukahlukene, njenge: ama-alloys asekelwe ensimbi-nickel, ama-alloys asekelwe ku-zinc, ama-alloys e-aluminium, ingilazi, i-ceramics, amapulasitiki, ama-semiconductors nezinye izinto.

I-tin Plating:
Ithini inokuqina okuphezulu kwamakhemikhali.Akulula ukuncibilika ezixazululweni ze-sulfuric acid, i-nitric acid ne-hydrochloric acid.Ama-sulfide awanawo umthelela ethini.Ithini libuye lizinze kuma-asidi aphilayo, futhi izinhlanganisela zawo azinabuthi.Isetshenziswa kabanzi ezitsheni zemboni yokudla kanye nezingxenye zezindiza, ukuhamba kwemikhumbi kanye nemishini yomsakazo.Ingasetshenziselwa ukuvimbela izintambo zethusi ukuthi zingathintwa isulfure enjolobeni futhi njengongqimba oluvikelayo lwezindawo ezingezona i-nitriding.
Izinto ezisetshenziswayo: insimbi, ithusi, i-aluminium kanye nama-alloys awo

Ingxube ye-Copper tin:
I-electroplating ye-Copper-tin alloy iwukuba icwecwe le-copper-tin alloy ezingxenyeni ngaphandle kwe-nickel plating, kodwa i-chromium plating ngokuqondile.I-Nickel iyinsimbi eyivelakancane futhi eyigugu.Njengamanje, i-copper-tin alloy electroplating isetshenziswa kabanzi embonini ye-electroplating ukuze ithathe indawo ye-nickel plating, enekhono elihle lokulwa nokugqwala.
Izinto ezisetshenziswayo: izingxenye zensimbi, izingxenye zethusi nezethusi.
