Ukwelashwa kokuqeda okungaphezulu kwakha indlela yenqubo yongqimba lwangaphezulu endaweni engaphansi, enezakhiwo ezihlukile zemishini, ezomzimba nezamakhemikhali ezinokwakheka kwe-substrate.Inhloso yokwelashwa okungaphezulu ukuhlangabezana nokumelana nokugqwala komkhiqizo, ukumelana nokuguga, ukuhlobisa noma ezinye izidingo ezikhethekile zokusebenza.
Ngokuya ngokusetshenziswa, indlela yokwelapha engaphezulu ingahlukaniswa ngezigaba ezilandelayo.
Indlela ye-Electrochemical
Le ndlela iwukusebenzisa ukusabela kwe-electrode ukwakha i-coating endaweni yokusebenza.Izindlela eziyinhloko yilezi:
(A) I-Electroplating
Esixazululweni se-electrolyte, i-workpiece yi-cathode, engakha ifilimu yokugqoka ebusweni ngaphansi kwesenzo samanje sangaphandle, esibizwa ngokuthi i-electroplating.
(B) I-anodization
Esixazululweni se-electrolyte, i-workpiece iyi-anode, engakha ungqimba olune-anodized ebusweni ngaphansi kwesenzo samanje sangaphandle, esibizwa ngokuthi i-anodizing, njenge-aluminium alloy anodizing.
I-anodization yensimbi ingenziwa ngezindlela zamakhemikhali noma ze-electrochemical.Chemical indlela ifakwa workpiece zibe uketshezi anodized, kuyoba ifilimu anodized, ezifana steel bluing ukwelashwa.
Indlela yamakhemikhali
Le ndlela isebenzisa ukusebenzisana kwamakhemikhali ngaphandle kwamanje ukwenza ifilimu enamathela endaweni yokusebenza.Izindlela eziyinhloko yilezi:
(A) ukwelashwa kwefilimu yokuguqulwa kwamakhemikhali
Esixazululweni se-electrolyte, i-workpiece uma ingekho yamanje yangaphandle, ngesixazululo sezinto zamakhemikhali kanye nokusebenzisana kwe-workpiece ukuze kwakhiwe ukunamathela enqubweni yayo engaphezulu, eyaziwa ngokuthi ukwelashwa kwefilimu yokuguqulwa kwamakhemikhali.
Ngoba ukusebenzelana phakathi kwezinto zamakhemikhali zesisombululo kanye nomsebenzi ngaphandle kwamanje kwangaphandle okungakha ifilimu enamathela endaweni yokusebenza, ebizwa ngokuthi ifilimu yokuguqulwa kwamakhemikhali.Okufana ne-bluing, i-phosphating, i-passivating, ukwelashwa kukasawoti we-chromium nokunye.
(B) Ukufakwa kwe-electroless
Esixazululweni se-electrolyte ngenxa yokuncipha kwezinto zamakhemikhali, ezinye izinto ezifakwa phezu kwendawo yokusebenza ukuze zenze inqubo yokunamathela, ebizwa ngokuthi i-electroless plating, njenge-electroless nickel plating, i-electroless copper plating.
Indlela yokucubungula eshisayo
Le ndlela yenza izinto ezincibilikayo zincibilike noma zisakazeke ezishisayo ezimweni zokushisa eziphezulu ukuze zakhe ifilimu yokumboza phezu kwendawo yokusebenza.Izindlela eziyinhloko yilezi:
(A) I-Hot Dip Plating
Faka izingxenye zensimbi ensimbi encibilikisiwe ukuze wenze ifilimu yokumboza phezu kwendawo yokusebenza, ebizwa ngokuthi i-hot-dip plating, njenge-hot-dip galvanizing, i-aluminium eshisayo nokunye.
(B) Ukufafaza okushisayo
Inqubo yokufaka i-athomu nokufafaza insimbi encibilikisiwe phezu kwendawo yokusebenza ukuze kwakhiwe ifilimu yokumboza ibizwa ngokuthi isifutho esishisayo, njengokufafaza okushisayo kwe-zinc, ukufuthwa okushisayo kwe-aluminium nokunye.
(C) Ukunyathela okushisayo
I-foil yensimbi eshisayo, ikhava ecindezelwe ebusweni bomsebenzi ukuze yakhe inqubo yefilimu yokuhlanganisa, ebizwa ngokuthi i-hot stamping, njenge-foil eshisayo ye-foil nokunye.
(D) Ukwelashwa kokushisa kwamakhemikhali
Ukwenza ukuthintana kwe-workpiece nekhemikhali bese uvumela ezinye izakhi ukuthi zingene endaweni yokusebenzela endaweni enezinga lokushisa eliphezulu, elibiza ukwelashwa kokushisa kwamakhemikhali, njenge-nitriding, carburizing njalonjalo.
Ezinye izindlela
Ikakhulukazi mechanical, chemical, electrochemical, indlela ngokomzimba.Izindlela eziyinhloko yilezi:
(A)I-Painting coating (B) I-Strike Plating (C) i-laser surface finish (D) Ubuchwepheshe befilimu obuqine kakhulu (E) I-Electrophoresis nokufutha nge-electrostatic
