Tasirin plating
Da dabara na plating bayani kai tsaye rinjayar da irin, taurin da sa juriya na shafi karfe. Tare da sigogi daban-daban na tsari, kauri, yawa da damuwa na ƙarfe crystallization shafi kuma za a iya sarrafawa.
Don samar da kayan aikin lantarki na lu'u-lu'u, yawancin mutane suna amfani da nickel ko nickel-cobalt gami. Ba tare da tasirin plating najasa ba, abubuwan da ke shafar zubar da rufin sune:
(1) Tasirin damuwa na ciki An samar da damuwa na ciki na rufi a cikin tsarin lantarki, da kuma abubuwan da aka haɗa a cikin raƙuman ruwa da narkar da su da samfurori da kuma hydroxide zasu kara yawan damuwa na ciki.
Damuwar macroscopic na iya haifar da kumfa, fashewa da fadowa daga rufin a cikin tsarin ajiya da amfani.
Don nickel plating ko nickel-cobalt gami, damuwa na ciki ya bambanta sosai, mafi girman abun ciki na chloride, mafi girman damuwa na ciki. Don babban gishiri na maganin maganin nickel sulfate, damuwa na ciki na maganin watt ɗin ya kasance ƙasa da na sauran maganin shafawa. Ta hanyar ƙara haɓakar kwayoyin halitta ko danniya mai kawar da damuwa, za a iya rage yawan damuwa na ciki na macro na rufi kuma za a iya ƙara yawan damuwa na ciki.
(2) Tasirin juyin halittar hydrogen a cikin kowane bayani na plating, ba tare da la'akari da ƙimar PH ba, koyaushe akwai takamaiman adadin ions na hydrogen saboda rarrabuwar kwayoyin ruwa. Sabili da haka, a ƙarƙashin yanayin da ya dace, ba tare da la'akari da plating a cikin acidic, tsaka tsaki, ko alkaline electrolyte, sau da yawa ana samun hazo hydrogen a cikin cathode tare da hazo na ƙarfe. Bayan ions hydrogen sun ragu a cathode, wani ɓangare na hydrogen ya tsere, kuma wani sashi yana shiga cikin matrix karfe da kuma shafi a cikin yanayin hydrogen atomic. Yana karkatar da lattice, yana haifar da babban damuwa na ciki, kuma yana sa suturar ta lalace sosai.
Tasirin tsarin plating
Idan an cire abun da ke ciki na maganin electroplating da sauran tasirin sarrafawa, rashin ƙarfi na wutar lantarki a cikin tsarin lantarki shine muhimmiyar dalilin asarar sutura. Tsarin samar da lantarki na kayan aikin lu'u-lu'u na lantarki ya bambanta da sauran nau'ikan lantarki. A plating tsari na electroplating lu'u-lu'u kayan aikin hada da komai plating (tushe), yashi shafi da thickening tsari.
