Unyango lokugqitywa komphezulu kukwenza indlela yenkqubo yomaleko womphezulu kumphezulu we-substrate we-substrate, eneempawu ezahlukeneyo zoomatshini, ezibonakalayo kunye neekhemikhali kunye ne-substrate material.Injongo yonyango lomphezulu kukuhlangabezana nokumelana ne-corrosion yemveliso, ukumelana nokunxiba, ukuhlobisa okanye ezinye iimfuno ezikhethekileyo zokusebenza.
Ngokuxhomekeke kusetyenziso, ubuchule bonyango lomphezulu bunokwahlulwa ngokwezi ndidi zilandelayo.
Indlela ye-Electrochemical
Le ndlela kukusetyenziswa kwe-electrode reaction ukwenza i-coating kwi-workpiece surface.Ezona ndlela ziphambili zezi:
(A) I-Electroplating
Kwisisombululo se-electrolyte, i-workpiece yi-cathode, enokuthi yenze ifilimu yokugqoka phezu komhlaba phantsi kwesenzo sombane wangaphandle, obizwa ngokuba yi-electroplating.
(B) I-Anodization
Kwisisombululo se-electrolyte, i-workpiece yi-anode, enokuthi yenze umaleko we-anodized phezu komhlaba phantsi kwesenzo sombane wangaphandle, obizwa ngokuba yi-anodizing, njenge-aluminium alloy anodizing.
I-anodization yensimbi inokuqhutywa ngeendlela zeekhemikhali okanye ze-electrochemical.Indlela yeMichiza ibeka i-workpiece kwi-liquid anodized, iya kwenza ifilimu ye-anodized, efana ne-steel bluing treatment.
Indlela yeMichiza
Le ndlela isebenzisa ukusebenzisana kweekhemikhali ngaphandle kwangoku ukwenza ifilimu yokwambathisa kumphezulu womsebenzi.Ezona ndlela ziphambili zezi:
(A) unyango lwefilimu yokuguqulwa kweekhemikhali
Kwisisombululo se-electrolyte, i-workpiece ngokungabikho kwangoku kwangaphandle, ngesisombululo sezinto zekhemikhali kunye nentsebenziswano ye-workpiece ukwenza i-coating kwi-surface process yayo, eyaziwa ngokuba yi-chemical conversion film treatment.
Kungenxa yokuba ukusebenzisana phakathi kwezinto zeekhemikhali zesisombululo kunye ne-workpiece ngaphandle kwangoku yangaphandle enokuthi yenze ifilimu yokugubungela kwindawo yokusebenza, ebizwa ngokuba yifilimu yokuguqulwa kweekhemikhali.Okufana ne-bluing, i-phosphating, i-passivating, unyango lwetyuwa lwe-chromium njalo njalo.
(B) Ukufakwa kwe-electroless plating
Kwisisombululo se-electrolyte ngenxa yokunciphisa izinto zekhemikhali, ezinye izinto ezifakwe kumphezulu we-workpiece ukwenza inkqubo yokugquma, ebizwa ngokuba yi-electroless plating, njenge-electroless nickel plating, i-electroless copper plating.
Indlela yokulungisa iThermal
Le ndlela yenza ukunyibilika kwezinto okanye ukusasazwa kwe-thermal kwiimeko zobushushu obuphezulu ukwenza ifilimu yokwambathisa kumphezulu we-workpiece.Ezona ndlela ziphambili zezi:
(A) Ukufakwa kwediphu eshushu
Beka iindawo zentsimbi kwintsimbi etyhidiweyo ukwenza ifilimu yokugquma phezu kwendawo yokusebenza, ebizwa ngokuba yi-hot-dip plating, efana ne-hot-dip galvanizing, i-aluminiyam eshushu njalo njalo.
(B) Ukutshiza nge-thermal
Inkqubo yokutshiza i-athomu kunye nokutshiza isinyithi esityhidiweyo phezu kwendawo yokusebenza ukwenza ifilimu yokugubungela ibizwa ngokuba yi-thermal spraying, njengokutshiza kwe-thermal ye-zinc, ukutshiza kwe-thermal ye-aluminium kunye nokunye.
(C) Isitampu esishushu
Ifoyile yesinyithi ifudunyezwe, icinezele ukugubungela umphezulu wesixhobo sokusebenza ukwenza inkqubo yokugquma ifilimu, ebizwa ngokuba yi-hot stamping, efana nefoyile eshushu njalo njalo.
(D) Unyango lobushushu beMichiza
Ukwenza unxibelelwano lwesixhobo sokusebenza kunye neekhemikhali kwaye uvumele ezinye izinto zibe kwindawo yokusebenza kwindawo yobushushu obuphezulu, obubizwa ngokuba lunyango lobushushu bekhemikhali, njenge-nitriding, carburizing njalo njalo.
Ezinye iindlela
Ngokukodwa oomatshini, iikhemikhali, i-electrochemical, indlela yomzimba.Ezona ndlela ziphambili zezi:
(A)Ipeyinti yokupeyinta (B) Ukubetha ucwecwe (C) ukugqiba ngelaser umphezulu (D) Ubuchwephesha befilimu obuqine kakhulu (E) I-Electrophoresis kunye nokutshiza nge-electrostatic
