Tasirin maganin da aka riga aka yi wa fenti
Tsarin maganin matrix na ƙarfe kafin shiga tankin plating ana kiransa maganin pre-plating. Maganin pre-plating ya haɗa da: gogewa ta injiniya, cire mai, zaizayar ƙasa da matakan kunnawa. Manufar maganin pre-plating shine cire burr, mai, fim ɗin oxide, tsatsa da fatar oxidation a saman matrix, don fallasa ƙarfen matrix don haɓaka layin ƙarfe akai-akai da kuma samar da ƙarfin ɗaurewa tsakanin molecular.
Idan maganin da aka riga aka yi wa plating bai yi kyau ba, saman matrix ɗin yana da siririn fim ɗin mai da fim ɗin oxide, ba za a iya fallasa yanayin ƙarfe na matrix ɗin gaba ɗaya ba, wanda zai hana samuwar ƙarfen da aka yi wa fenti da ƙarfen matrix, wanda kawai injina ne, ƙarfin ɗaurewa ba shi da kyau. Saboda haka, rashin kyawun magani kafin a yi wa fenti shine babban dalilin zubar da shafi.
Tasirin farantin
Tsarin maganin plating yana shafar nau'in, tauri da juriyar lalacewa na ƙarfen rufi kai tsaye. Tare da sigogi daban-daban na tsari, ana iya sarrafa kauri, yawa da damuwa na lu'ulu'u na ƙarfen rufi.
Don samar da kayan aikin lantarki na lu'u-lu'u, yawancin mutane suna amfani da gami na nickel ko nickel-cobalt. Ba tare da tasirin ƙazanta na plating ba, abubuwan da ke shafar zubar da shafi sune:
(1) Tasirin damuwa ta ciki Damuwar ciki na rufin ana samar da ita ne a lokacin da ake sanya wutar lantarki a cikin wutar lantarki, kuma ƙarin abubuwan da ke cikin raƙuman da aka narkar da su da samfuran ruɓewarsu da hydroxide za su ƙara damuwa ta ciki.
Damuwa ta macroscopic na iya haifar da kumfa, fashewa da faɗuwa daga murfin yayin adanawa da amfani.
Ga plating na nickel ko nickel-cobalt, damuwar ciki ta bambanta sosai, mafi girman abun ciki na chloride, mafi girman damuwar ciki. Ga babban gishirin maganin shafawa na nickel sulfate, damuwar ciki na maganin shafawa na watt bai kai na sauran maganin shafawa ba. Ta hanyar ƙara haske na halitta ko wakili mai kawar da damuwa, za a iya rage damuwar ciki ta macro na murfin sosai kuma za a iya ƙara yawan damuwar ciki.
(2) Tasirin juyin halittar hydrogen a cikin kowace mafita ta plating, ba tare da la'akari da ƙimar PH ɗinsa ba, koyaushe akwai wani adadin ions na hydrogen saboda rabuwar ƙwayoyin ruwa. Saboda haka, a ƙarƙashin yanayi mai dacewa, ba tare da la'akari da plating a cikin wani abu mai acidic, tsaka tsaki, ko alkaline electrolyte ba, sau da yawa akwai ruwan hydrogen a cikin cathode tare da ruwan ƙarfe. Bayan ions na hydrogen sun ragu a cathode, wani ɓangare na hydrogen yana fita, kuma wani ɓangare yana shiga cikin ƙarfen matrix da shafi a cikin yanayin hydrogen na atomic. Yana karkatar da layin, yana haifar da babban damuwa na ciki, kuma yana sa murfin ya lalace sosai.
Tasirin tsarin shafa
Idan aka cire abubuwan da ke cikin maganin electroplating da sauran tasirin sarrafa tsari, gazawar wutar lantarki a cikin tsarin electroplating muhimmin dalili ne na asarar shafi. Tsarin samar da kayan aikin lu'u-lu'u na electroplating ya bambanta sosai da sauran nau'ikan electroplating. Tsarin plating na kayan aikin lu'u-lu'u na electroplating ya haɗa da plating mara komai (tushe), rufin yashi da tsarin kauri. A cikin kowane tsari, akwai yuwuwar matrix ya bar maganin plating, wato, dogon ko gajeriyar katsewar wutar lantarki. Saboda haka, amfani da tsari mai ma'ana, tsari na iya rage fitowar abin da ke haifar da zubar da shafi.
