Dangane da yadda ake amfani da shi, ana iya rarraba dabarar jiyya ta saman zuwa sassa masu zuwa.
Hanyoyin lantarki
Wannan hanya ita ce amfani da amsawar lantarki don samar da shafi a cikin farfajiyar aiki.Manyan hanyoyin sune:
(A) Electrolating
A cikin electrolyte bayani, da workpiece ne cathode, wanda zai iya samar da wani shafi fim a kan surface karkashin mataki na waje halin yanzu, wanda ake kira electroplating.
(B) Anodization
A cikin electrolyte bayani, da workpiece ne anode, wanda zai iya samar da anodized Layer a kan surface karkashin aikin na waje halin yanzu, wanda ake kira anodizing, kamar aluminum gami anodizing.
Ana iya aiwatar da anodization na karfe ta hanyar sinadarai ko hanyoyin lantarki.Chemical Hanyar da aka sa workpiece a cikin anodized ruwa, shi zai samar da wani anodized fim, kamar karfe bluing magani.
Hanyar sinadarai
Wannan hanyar tana amfani da hulɗar sinadarai ba tare da halin yanzu ba don samar da fim ɗin shafi akan farfajiyar aikin.Manyan hanyoyin sune:
(A) maganin fim ɗin canza sinadarai
A cikin electrolyte bayani, da workpiece a cikin rashi na waje halin yanzu, da bayani na sinadaran abubuwa da workpiece hulda don samar da wani shafi a kan ta surface tsari, da aka sani da sinadaran hira film magani.
Saboda hulɗar tsakanin sinadaran abubuwa na bayani da workpiece ba tare da waje halin yanzu wanda zai iya samar da shafi fim a kan workpiece surface, wanda ake kira sinadaran hira film.Kamar bluing, phosphating, passivating, chromium gishiri magani da sauransu.
(B) Plating mara amfani
A cikin maganin electrolyte saboda raguwar abubuwan sinadarai, wasu abubuwan da aka ajiye a saman kayan aikin don samar da tsarin sutura, wanda ake kira electroless plating, irin su electroless nickel plating, electroless copper plating.
Hanyar sarrafa thermal
Wannan hanyar tana yin kayan narkewa ko yaduwa na thermal a cikin yanayin yanayin zafi don samar da fim ɗin shafi a saman kayan aikin.Manyan hanyoyin sune:
(A) Ruwan tsoma zafi
Saka sassa na ƙarfe a cikin narkakken ƙarfe don samar da fim ɗin shafa akan saman kayan aikin, wanda ake kira plating mai zafi, irin su galvanizing mai zafi, zafi mai zafi da sauransu.
(B) Fushin zafi
Tsarin atomizing da fesa narkakkar karfen a saman farfajiyar aikin don samar da fim ɗin shafa ana kiransa spraying thermal, kamar feshin zafin jiki na zinc, feshin zafin jiki na aluminum da sauransu.
(C) Tambarin zafi
The karfe tsare mai tsanani, matsi rufe surface na workpiece samar da wani shafi film tsari, wanda ake kira zafi stamping, kamar zafi tsare tsare da sauransu.
(D) Maganin zafi na sinadarai
Yin hulɗar aiki tare da sinadaran kuma bari wasu abubuwa a cikin farfajiyar aiki a cikin yanayin zafi mai zafi, wanda ake kira maganin zafi mai zafi, irin su nitriding, carburizing da sauransu.
