I-Electroplating yindlela apho isinyithi sihlanjululwa kwi-electrolyte ngesenzo somjelo osetyenzisiweyo kwaye sifakwe phezu kwendawo yokufumana i-metal covering layer.
Iigalvanized:
I-Zinc i-corrored ngokulula kwi-acids, i-alkali, kunye ne-sulfides.Umaleko we-zinc ngokuqhelekileyo uyagqithiswa.Emva kokudlula kwisisombululo sechromate, ifilimu yokudlula eyenziweyo ayilula ukusebenzisana nomoya omanzi, kwaye amandla okulwa nokubola aphuculwa kakhulu.Kumoya owomileyo, i-zinc izinzile kwaye akukho lula ukutshintsha umbala.Kumanzi kunye nomoya omanzi, uphendula nge-oksijeni okanye i-carbon dioxide ukuze wenze i-oxide okanye ifilimu ye-alkaline carbonic acid, enokuthintela i-zinc ukuba iqhubeke i-oxidize kwaye idlala indima yokukhusela.
Izinto ezisebenzayo: intsimbi, iinxalenye zentsimbi
chrome:
I-Chromium izinzile kakhulu kwi-atmosfera efumileyo, i-alkali, i-nitric acid, i-sulfide, izisombululo ze-carbonate kunye ne-organic acids, kwaye i-soluble lula kwi-hydrochloric acid kunye ne-asidi ye-sulfuric egxininisiweyo eshushu.Ukungalungi kukuba iqinile, ibhityile, kwaye kulula ukuwa.Ukufakwa ngokuthe ngqo kwechromium kumphezulu wamalungu entsimbi njengomaleko ochasene nokubola akulunganga.Ngokubanzi, i-electroplating enemigangatho emininzi (okt ukucwenga kobhedu → nickel → chromium) inokufikelela injongo yokuthintela umhlwa kunye nokuhombisa.Okwangoku, isetyenziselwa ngokubanzi ukuphucula ukunyanzeliswa kwamacandelo, ubungakanani bokulungisa, ukubonakalisa ukukhanya kunye nokuhlobisa.
Izixhobo ezisebenzayo: intsimbi yeferrous, ubhedu kunye nealloy yobhedu zero zokuhombisa ichrome yokucwenga, ukugquma kwechrome okunganxitywayo
Ukucwenga ubhedu:
I-Copper ayizinzile emoyeni, kwaye kwangaxeshanye, inamandla aphezulu kwaye ayikwazi ukukhusela ezinye isinyithi kwi-corrosion.Nangona kunjalo, i-copper ine-conductivity ephezulu yombane, i-copper plating layer iqinile kwaye ilungile, idityaniswe ngokuqinileyo kunye nesinyithi esisisiseko, kwaye inokusebenza kakuhle kokupholisa. enye i-electroplating, njengoluhlu olukhuselayo lokukhusela i-carburization, kunye nokunciphisa ukungqubuzana okanye ukuhlobisa kwi-bearing.
Izinto ezisebenzayo: isinyithi esimnyama, ubhedu kunye ne-alloy ye-alloy nickel-plated, i-chrome-plated bottom layer.
I-Nickel plating:
I-nickel inozinzo oluhle lwekhemikhali kwi-atmosfera kunye ne-lye, kwaye akulula ukutshintsha umbala, kodwa inyibilika ngokulula kwi-dilute nitric acid.Kulula ukudlula kwi-asidi ye-nitric egxininisiweyo, kwaye i-disadvantage yayo yi-porosity.Ukoyisa le ntsilelo, i-multi-layer metal plating ingasetyenziswa, kwaye i-nickel ngumaleko ophakathi.I-nickel plating layer inobulukhuni obuphezulu, kulula ukuyipolisha, inokukhanya okuphezulu kwaye inokunyusa ukubonakala kunye nokuchasana, kwaye inokumelana nokugqwala okulungileyo.
Izinto ezisebenzayo: zinokufakwa kumphezulu wezinto ezahlukeneyo, ezinje: i-alloys esekwe yintsimbi-nickel, i-zinc-based alloys, i-aluminium alloys, iglasi, iiseramikhi, iiplastiki, iisemiconductors kunye nezinye izinto.
Ukufakwa kwenkcenkce:
I-tin inozinzo oluphezulu lwekhemikhali.Akulula ukunyibilika kwizisombululo ze-sulfuric acid, i-nitric acid kunye ne-hydrochloric acid.Iisulfides azinampembelelo kwitoti.I-Tin nayo izinzile kwi-asidi ye-organic, kwaye i-compounds yayo ayinayo ityhefu.Isetyenziswa kakhulu kwizikhongozeli zeshishini lokutya kunye neenxalenye zenqwelomoya, ukuhamba ngenqanawa kunye nezixhobo zikanomathotholo.Ingasetyenziselwa ukuthintela iingcingo zobhedu ukuba zingachatshazelwa yisalfure kwirabha kwaye njengomaleko okhuselayo weendawo ezingezizo i-nitriding.
Izinto ezisebenzayo: intsimbi, ubhedu, i-aluminium kunye ne-alloys yazo
Ingxubevange yenkcenkce yobhedu:
I-copper-tin alloy electroplating kukupleyita ingxubevange yobhedu-tin kumalungu ngaphandle kokufakwa kwe-nickel, kodwa ngokuthe ngqo kwi-chromium yokubeka.I-nickel yintsimbi enqabileyo nexabisekileyo.Okwangoku, i-copper-tin alloy electroplating isetyenziswa kakhulu kwishishini le-electroplating ukuze ithathe indawo yokubeka i-nickel, enekhono elihle lokuchasa ukubola.
Izinto ezisebenzayo: iinxalenye zetsimbi, ubhedu kunye nobhedu lwe-alloy.
