Izixhobo zedayimane ze-electroplated zibandakanya iinkqubo ezininzi kwinkqubo yokuvelisa, nayiphi na inkqubo ayanele, iya kubangela ukuba i-coating ziwe.
Isiphumo sonyango lwangaphambili
Inkqubo yonyango ye-matrix yensimbi ngaphambi kokungena kwi-tank yokucoca ibizwa ngokuba yi-pre-plating treatment. Unyango lwangaphambili lwe-plating lubandakanya: ukupolisha ngoomatshini, ukususwa kweoli, ukukhukuliseka kunye namanyathelo okusebenza. Injongo yonyango lwangaphambili kukususa i-burr, i-oyile, ifilimu ye-oxide, irusi kunye nesikhumba se-oxidation kumphezulu we-matrix, ukuze uveze isinyithi se-matrix ukukhulisa i-lattice yesinyithi ngokuqhelekileyo kwaye yenze i-intermolecular force force.
Ukuba unyango lwe-pre-plating alulungile, umphezulu we-matrix unefilimu yeoli encinci kakhulu kunye nefilimu ye-oxide, umlingiswa wensimbi yensimbi ye-matrix ayinakubonakaliswa ngokupheleleyo, eya kuthintela ukubunjwa kwentsimbi yokugubungela kunye nentsimbi ye-matrix, eyona nto i-inlay yomatshini, amandla okubopha ahluphekile. Ke ngoko, ukunganyangeki kakuhle phambi kokutyalwa ngoyena nobangela wokuphalala kwengubo.
Isiphumo sokutyalwa
Ifomula yesisombululo se-plating ichaphazela ngokuthe ngqo uhlobo, ubunzima kunye nokuxhatshazwa kokugqoka kwentsimbi yokugubungela. Ngeeparamitha zenkqubo ezahlukeneyo, ubukhulu, ubuninzi kunye noxinzelelo lwe-crystallization yentsimbi yokugquma inokulawulwa.
Ukuveliswa kwezixhobo ze-diamond electroplating, abaninzi abantu basebenzisa i-nickel okanye i-nickel-cobalt alloy. Ngaphandle kwempembelelo yokungcola kweplating, izinto ezichaphazela ukuchithwa kokugquma zezi:
(1) Impembelelo yoxinzelelo lwangaphakathi Uxinzelelo lwangaphakathi lwengubo luveliswa kwinkqubo ye-electrodeposition, kwaye izongezo kwi-wave edibeneyo kunye nemveliso yazo yokubola kunye ne-hydroxide iya kwandisa uxinzelelo lwangaphakathi.
Uxinzelelo lwe-macroscopic lunokubangela iibhubhu, ukuqhekeka kunye nokuwa kwengubo kwinkqubo yokugcina kunye nokusetyenziswa.
Kwi-nickel plating okanye i-nickel-cobalt alloy, uxinzelelo lwangaphakathi luhluke kakhulu, luphezulu umxholo we-chloride, ngakumbi uxinzelelo lwangaphakathi. Kwityuwa ephambili yesisombululo se-nickel sulfate, uxinzelelo lwangaphakathi lwesisombululo se-watt singaphantsi kunesinye isisombululo sokugubungela. Ngokongeza i-organic luminent okanye i-arhente yokuphelisa uxinzelelo, uxinzelelo lwangaphakathi lwangaphakathi lwe-macro lunokuncitshiswa kakhulu kwaye uxinzelelo lwangaphakathi oluncinci lunokwandiswa.
(2) Isiphumo se-hydrogen evolution nakwesiphi na isisombululo se-plating, kungakhathaliseki ukuba yiyiphi ixabiso le-PH, kusoloko kukho umlinganiselo othile we-hydrogen ion ngenxa yokwahlukana kwee-molecule zamanzi. Ngoko ke, phantsi kweemeko ezifanelekileyo, kungakhathaliseki ukuba i-electrolyte ene-asidi, engathathi hlangothi, okanye yealkaline, kukho imvula ye-hydrogen kwi-cathode kunye nemvula yesinyithi. Emva kokuba ii-ion zehydrogen zinciphile kwi-cathode, inxalenye ye-hydrogen iyabaleka, kwaye inxalenye ingena kwi-matrix yesinyithi kunye nokugquma kwimeko ye-athom ye-hydrogen. Igqwetha i-lattice, ibangela uxinzelelo olukhulu lwangaphakathi, kwaye yenza ukuba i-coating ikhubazeke kakhulu.
Iziphumo zenkqubo yokucwenga
Ukuba ukubunjwa kwesisombululo se-electroplating kunye nezinye iziphumo zokulawula inkqubo azibandakanyi, ukungaphumeleli kwamandla kwinkqubo ye-electroplating kuyimbangela ebalulekileyo yokulahleka kwengubo. Inkqubo yokuvelisa i-electroplating yezixhobo zedayimani ze-electroplating zihluke kakhulu kwezinye iintlobo ze-electroplating. Inkqubo yokufakwa kwezixhobo zedayimani ye-electroplating ibandakanya ukufakwa okungenanto (isiseko), ukugquma kwesanti kunye nenkqubo yokuqina. Kwinkqubo nganye, kukho ithuba lokuba i-matrix ishiye isisombululo se-plating, oko kukuthi, ukuphuma kwamandla okude okanye okufutshane. Ke ngoko, ukusetyenziswa kwenkqubo esengqiqweni ngakumbi, inkqubo inokunciphisa ukuvela komcimbi wokuphalaza.
