Hanyoyin gogewa sun haɗa da gyaran injin injiniya, gogewar sinadarai, polishing electrolytic, polishing ultrasonic, polishing ruwa, da polishing abrasive.A yawancin samfuran mabukaci, sassan aluminum da aluminum gami ana goge su ta amfani da gogewar injina da gogewar lantarki, ko haɗin waɗannan hanyoyin guda biyu.Bayan inji polishing da electrolytic polishing, saman aluminum da aluminum gami sassa na iya cimma wani bayyanar kama da madubi surface na bakin karfe.Ƙarfe madubin yawanci ba wa mutane jin sauƙi, salon, da kuma babban matsayi, yana ba su jin daɗin soyayya ga samfurori ko ta yaya.Madubin karfe yana buƙatar magance matsalar bugu na yatsa.
4. Anodizing
A mafi yawan lokuta, sassan aluminum (ciki har da aluminum da aluminum alloys) ba su dace da lantarki ba kuma ba su da wutar lantarki.Maimakon haka, ana amfani da hanyoyin sinadarai irin su anodizing don maganin saman.Electroplating a kan aluminum sassa ya fi wuya da rikitarwa fiye da electroplating a karfe kayan kamar karfe, zinc gami, da kuma jan karfe.Babban dalili shi ne cewa sassan aluminum suna da wuyar samar da fim din oxide akan oxygen, wanda ke tasiri sosai ga mannewar murfin lantarki;Lokacin da aka nutsar da shi a cikin electrolyte, ƙarfin wutar lantarki mara kyau na aluminum yana da wuyar sauyawa tare da ions karfe tare da ingantacciyar ma'auni, ta haka yana rinjayar mannewar Layer na electroplating;Ƙimar haɓakar haɓakar sassan aluminum ya fi girma fiye da na sauran karafa, wanda zai shafi ƙarfin haɗin kai tsakanin sutura da sassan aluminum;Aluminum karfe ne na amphoteric wanda ba shi da kwanciyar hankali a cikin maganin acidic da alkaline electroplating mafita.
Anodic hadawan abu da iskar shaka yana nufin electrochemical hadawan abu da iskar shaka iskar shaka ko gami.Ɗaukar samfuran aluminum da aluminum gami (wanda ake magana da su azaman samfuran aluminium) azaman misalai, ana sanya samfuran aluminium a cikin madaidaicin electrolyte azaman anodes.Ƙarƙashin ƙayyadaddun yanayi da halin yanzu na waje, an kafa wani Layer na fim din aluminum oxide akan saman samfuran aluminum.Wannan Layer na aluminum oxide fim inganta surface taurin da kuma sa juriya na aluminum kayayyakin, kara habaka da lalata juriya na aluminum kayayyakin, da kuma utilizes da adsorption damar da babban adadin micropores a cikin bakin ciki Layer na oxide fim, Coloring da saman samfuran aluminium zuwa launuka masu kyau da launuka iri-iri, suna wadatar da maganganun launi na samfuran aluminium da haɓaka ƙa'idodin su.Anodizing ne yadu amfani a aluminum gami.
Anodizing yana iya ba da takamaiman yanki mai launuka daban-daban akan samfur, kamar anodizing launi biyu.Ta wannan hanyar, bayyanar ƙarfe na samfurin na iya nuna kwatancen launuka biyu kuma mafi kyawun nuna fifikon samfuran samfuran.Koyaya, tsarin anodizing launi biyu yana da rikitarwa kuma yana da tsada.
5. Zane na waya
Tsarin zane na saman waya tsari ne na balagagge wanda ke samar da layi na yau da kullun akan saman kayan aikin ƙarfe ta hanyar niƙa don cimma tasirin ado.Metal surface waya zane iya yadda ya kamata nuna irin karfe kayan da aka yadu amfani da yawa kayayyakin.Hanya ce ta gama gari ta fuskar ƙarfe kuma yawancin masu amfani suna son.Misali, ana amfani da tasirin zane na ƙarfe na ƙarfe akan sassa na samfur kamar ƙarshen fuskar fitilar fitilun ƙarfe na haɗin gwiwa, hannayen ƙofa, ɓangarorin kulle kulle, ƙananan fanatin sarrafa kayan aikin gida, murhu bakin karfe, fanatin kwamfutar tafi-da-gidanka, murfin majigi, da sauransu. Zane na waya zai iya haifar da sakamako kamar satin, da sauran tasirin da ke shirye don zane na waya.

Tasirin layin waya na iya bambanta sosai.Ana iya nuna alamun waya masu kyau a fili a saman sassan ƙarfe ta amfani da fasahar zanen waya.A gani, ana iya kwatanta shi azaman gashin gashi mai kyau yana haskakawa a cikin ƙarfe matte, yana ba da samfurin fasaha da fasaha.
6. Fesa
Manufar fesa saman akan sassan aluminum ba wai kawai don kare farfajiyar ba ne, har ma don haɓaka tasirin bayyanar sassan aluminum.The spraying jiyya na aluminum sassa yafi hada electrophoretic shafi, electrostatic foda spraying, electrostatic ruwa lokaci spraying, da fluorocarbon spraying.
Domin electrophoretic spraying, shi za a iya hade tare da anodizing.Manufar anodizing pretreatment shi ne don cire maiko, ƙazanta, da kuma na halitta oxide fim daga saman aluminum sassa, da kuma samar da wani uniform da kuma high quality anodizing fim a kan m surface.Bayan anodizing da electrolytic canza launi na aluminum sassa, electrophoretic shafi da ake amfani.Rufin da aka kafa ta hanyar rufin electrophoretic shine uniform kuma na bakin ciki, tare da nuna gaskiya, juriya na lalata, juriya mai girma, da kusanci ga rubutun ƙarfe.
Electrostatic foda spraying shi ne aiwatar da spraying foda shafi a saman saman aluminum sassa ta foda spraying gun, forming Layer na Organic polymer film, wanda yafi taka kariya da kuma ado rawa.The aiki manufa na electrostatic foda spraying an taƙaice bayyana a matsayin ake ji wani korau high irin ƙarfin lantarki zuwa foda spraying gun, grounding da mai rufi workpiece, forming wani high-voltage electrostatic filin tsakanin gun da workpiece, wanda yake da amfani ga foda spraying.
Electrostatic ruwa lokaci spraying yana nufin saman jiyya aiwatar da ake ji ruwa coatings zuwa saman aluminum gami profiles ta wani electrostatic spraying gun don samar da wani m da kuma ado Organic polymer film.
Fluorocarbon spraying, kuma aka sani da "curium man", shi ne babban-karshen fesa tsari tare da high farashin.Sassan da ke amfani da wannan tsari na fesa suna da kyakkyawan juriya ga dusashewa, sanyi, ruwan acid da sauran lalata, juriya mai ƙarfi da juriya UV, kuma suna iya jure yanayin yanayi mara kyau.Babban ingancin kayan kwalliyar fluorocarbon suna da ƙyalli na ƙarfe, launuka masu haske, da ma'ana mai ma'ana mai girma uku.Tsarin fesa fluorocarbon yana da ɗan rikitarwa kuma gabaɗaya yana buƙatar jiyya na feshi da yawa.Kafin fesa, ana buƙatar aiwatar da jerin hanyoyin da za a bi da su, wanda yake da rikitarwa kuma yana buƙatar manyan buƙatu.
