Uhlobo loku-1:I-Plating (okanye ukuguqulwa) iingubo
Ukufakwa kwesinyithi yinkqubo yokutshintsha umphezulu we-substrate ngokuwugquma ngezaleko ezibhityileyo zesinye isinyithi esifana ne-zinc, nickel, chromium okanye i-cadmium.
Ukufakwa kwesinyithi kunokuphucula ukuqina, ukukhuhlana komphezulu, ukuxhathisa ukubola kunye nenkangeleko yobuhle yecandelo.Nangona kunjalo, izixhobo zokucoca zisenokungabi zilungele ukuphelisa ukungafezeki komphezulu wesinyithi.Kukho iintlobo ezimbini eziphambili zokufakwa kwe-plating:
Uhlobo 2:Electroplating
Le nkqubo yokucwenga ibandakanya ukuntywiliselwa icandelo kwindawo yokuhlambela equlethe ioni zetsimbi zokwaleka.Umsinga othe ngqo uhanjiswa kwisinyithi, ubeke i-ion kwisinyithi kwaye wenze uluhlu olutsha phezu kwendawo.
Uhlobo 3:I-electroless plating
Le nkqubo ayisebenzisi umbane ngenxa yokuba i-autocatalytic plating engadingi amandla angaphandle.Kunoko, icandelo lesinyithi ligxininiswe kwizisombululo zethusi okanye ze-nickel ukuqalisa inkqubo ephula ii-ion zetsimbi kwaye yenza i-chemical bond.
Uhlobo 4:Anodizing
Inkqubo ye-electrochemical enegalelo ekudalweni kwexesha elide, elinomtsalane, kunye ne-corrosion-resistant anodic oxide finish.Oku kugqitywa kusetyenziswa ngokufunxa isinyithi kwibhafu ye-asidi ye-electrolyte ngaphambi kokuba ugqithise umsinga wombane phakathi.I-aluminiyam isebenza njenge-anode, kunye ne-cathode egcinwe ngaphakathi kwetanki ye-anodizing.
Iiyoni zeoksijini ezikhutshwa ngumxube we-electrolyte kunye neeathom ze-aluminiyam ukwenza i-anodic oxide kumphezulu wendawo yokusebenza.I-Anodizing, ngoko ke, i-oxidation elawulwa kakhulu ye-metal substrate.Ihlala isetyenziselwa ukugqiba iinxalenye ze-aluminiyam, kodwa iyasebenza nakwizinyithi ezingenayo i-ferrous ezifana ne-magnesium kunye ne-titanium.
Uhlobo 5:Ukugaya isinyithi
Oomatshini bokugaya basetyenziswa ngabavelisi ukugudisa imiphezulu yesinyithi ngokusetyenziswa kwe-abrasives.Sesinye sezigaba zokugqibela kwinkqubo yomatshini, kwaye inceda ukunciphisa uburhabaxa bomphezulu obushiywe kwintsimbi kwiinkqubo zangaphambili.
Baninzi oomatshini bokucola abakhoyo, ngamnye ubonelela ngamanqanaba ahlukeneyo okuguda.Iigrinder ezingaphezulu ngabona matshini baxhaphakileyo basetyenziswa, kodwa zininzi ezinye iigrinder ezikhethekileyo ezifumanekayo ezifana neBlanchard grinders kunye negrinder engenaziko.
Uhlobo 6:Ukupholisha/Ukubhuqa
Ngokucolwa kwentsimbi, izinto ezirhabaxa zisetyenziselwa ukunciphisa uburhabaxa bomphezulu wealloyi yentsimbi emva kokuba itshintshwe ngoomatshini.Ezi powders abrasive zisetyenziswa ngokudityaniswa namavili azivelayo okanye esikhumba ukupolisha kunye nokubhubhuza imiphezulu yesinyithi.
Ngaphandle kokunciphisa uburhabaxa bomphezulu, ukupolisha kunokuphucula inkangeleko yenxalenye - kodwa le yinjongo enye kuphela yokupolisha.Kumashishini athile, ukupolisha kusetyenziselwa ukudala izitya ezicocekileyo kunye namalungu.
Uhlobo 7:Electropolishing
Inkqubo ye-electropolishing yi-inverse yenkqubo ye-electroplating.I-Electropolishing isusa ii-ion zetsimbi kumphezulu wezinto zetsimbi kunokuba uzibeke.Ngaphambi kokusebenzisa umbane wombane, i-substrate ibhaptizwa kwindawo yokuhlamba i-electrolyte.I-substrate iguqulwa ibe yi-anode, kunye ne-ion ephuma kuyo ukuphelisa iziphene, i-rust, ukungcola kunye nokunye.Ngenxa yoko, umphezulu uyakhazimliswa kwaye ugudile, akukho ziqhuma okanye inkunkuma engaphezulu.
Uhlobo 8:Ukupeyinta
Ukwaleka ligama elibanzi eliquka amacandelwana ahlukeneyo okugqiba umphezulu.Olona khetho luqhelekileyo kwaye lungabizi kakhulu kukusebenzisa iipeyinti zorhwebo.Ezinye iipeyinti zingongeza umbala kwimveliso yentsimbi ukuze ibonakale ibonakale.Ezinye zikwasetyenziselwa ukuthintela umhlwa.
Uhlobo 9:Ukugquma umgubo
I-powder coating, uhlobo lwanamhlanje lomzobo, lukwakhona.Isebenzisa i-electrostatic charge, incamathelisa amasuntswana omgubo kwiindawo zentsimbi.Ngaphambi kokuba uphathwe ngobushushu okanye imisebe ye-ultraviolet, iinqununu ze-powder zigubungela ngokulinganayo izinto eziphathekayo.Le nkqubo iyakhawuleza kwaye iyasebenza ekupeyinteni izinto zetsimbi ezifana neefreyimu zebhayisekile, iinxalenye zemoto kunye nokwenziwa ngokubanzi.
Uhlobo 10:Ukuqhushumba
Ukuqhuma kwe-Abrasive ngokuqhelekileyo kusetyenziselwa iimveliso ezifuna i-matte texture engaguqukiyo.Yindlela yexabiso eliphantsi lokudibanisa ukucocwa komhlaba kunye nokugqiba kwintsebenzo enye.
Ngethuba lenkqubo yokuqhuma, i-high-pressure abrasive flow flows i-metal surface ukuze iguqule ukuthungwa, isuse i-debris kwaye ivelise ukugqiba okugudileyo.Ingasetyenziselwa ukulungiswa komphezulu, i-plating kunye nokugubungela ukwandisa ubomi bezinto zetsimbi.
Uhlobo 11:Ukubrasha
Ukuxukuxa ngumsebenzi ofanayo wokupholisha, ukuvelisa ukuthungwa komphezulu ofanayo kunye nokugudisa umphandle welungu.Inkqubo isebenzisa amabhanti e-abrasive kunye nezixhobo zokunika ukugqiba okuziinkozo kumphezulu.
Iziphumo zinokwahluka ngokuxhomekeke kwindlela ubuchule obusetyenziswa ngayo ngumenzi.Ukuhambisa ibhrashi okanye ibhanti kwicala elinye, umzekelo, kunokunceda ekudaleni imiphetho engqukuva kancinci kumphezulu.
Kunconywa kuphela ukuba kusetyenziswe kwizinto ezinqanda ukubola ezifana nensimbi engenasici, i-aluminium kunye nobhedu.
