Maganin oxidation na karafa shine samar da fim mai kariya a saman karafa ta hanyar hulɗar oxygen ko oxidants, wanda ke hana lalata karfe. Hanyoyin oxidation sun haɗa da oxidation thermal, alkaline oxidation, da acidic oxidation
Maganin oxidation na karafa shine samar da fim mai kariya a saman karafa ta hanyar hulɗar oxygen ko oxidants, wanda ke hana lalata karfe. Hanyoyin hadawan abu da iskar shaka sun hada da iskar shaka na thermal, alkaline oxidation, acidic oxidation (don karafa na baki), sinadarin oxidation, oxidation na anodic (don karafa mara nauyi), da sauransu.
Heat karfe kayayyakin zuwa 600 ℃ ~ 650 ℃ ta amfani da thermal hadawan abu da iskar shaka hanya, sa'an nan kuma bi da su da zafi tururi da kuma rage jamiái. Wata hanya kuma ita ce a nutsar da kayayyakin ƙarfe a cikin narkakken gishirin ƙarfe na alkali a kusan 300 ℃ don magani.
Lokacin amfani da alkaline hadawan abu da iskar shaka hanya, nutsad da sassa a cikin wani shiri bayani da kuma zafi su zuwa 135 ℃ zuwa 155 ℃. Tsawon lokacin jiyya ya dogara da abun ciki na carbon a cikin sassan. Bayan hadawan abu da iskar shaka magani na karfe sassa, kurkura su da ruwan sabulu dauke da 15g/L zuwa 20g/L a 60 ℃ zuwa 80 ℃ 2 zuwa 5 minutes. Sannan a wanke su da ruwan sanyi da ruwan zafi bi da bi sannan a bushe ko bushe su na tsawon mintuna 5 zuwa 10 (a zafin jiki na 80 ℃ zuwa 90 ℃).
Hanyar oxidation acid 3 ta ƙunshi sanya sassan a cikin maganin acidic don magani. Idan aka kwatanta da hanyar oxidation na alkaline, hanyar oxidation na acidic ya fi tattalin arziki. Fim ɗin kariya da aka samar akan saman ƙarfe bayan jiyya yana da juriya mai ƙarfi da ƙarfin injin fiye da fim ɗin bakin ciki da aka haifar bayan maganin iskar oxygenation na alkaline.
Hanyar hadawan abu da iskar shaka ta fi dacewa da maganin iskar shaka na karafa marasa tafe kamar aluminum, jan karfe, magnesium, da gami da su. Hanyar sarrafawa ita ce sanya sassan a cikin wani bayani da aka shirya, kuma bayan wani yanayi na oxidation a wani zafin jiki na wani lokaci, an samar da fim mai kariya, wanda za'a iya tsaftacewa kuma a bushe.
Anodizing Hanyar wata hanya ce ga hadawan abu da iskar shaka na wadanda ba ferrous karafa. Hanya ce ta amfani da sassa na ƙarfe azaman anodes da hanyoyin electrolytic don samar da fina-finai oxide akan saman su. Irin wannan fim ɗin oxide na iya zama fim ɗin wucewa tsakanin ƙarfe da fim ɗin rufewa, da haɓaka ƙarfin haɗin gwiwa tsakanin sutura da karafa, rage shigar da danshi, don haka tsawaita rayuwar sabis na sutura. Ana amfani da shi sosai a cikin ƙasan zanen zane.
