1. Menene bakin karfe?
Bakin karfe wani nau'in karfe ne.Karfe na nufin karfen da ke dauke da kasa da 2% carbon (c), da fiye da 2% iron.Alloy abubuwa kamar chromium (CR), nickel (Ni), manganese (MN), silicon (SI), titanium (TI) da molybdenum (MO) ana kara zuwa karfe a cikin smelting tsari don inganta aikin karfe da kuma sanya karfe ya sami juriya na lalata (watau babu tsatsa), wanda shine abin da muke kira bakin karfe.Misali, kayayyakin mu bakin karfe:banjos, swivel gidan karshen hadin gwiwa,matsi na gida,yawan shaye-shaye, da dai sauransu.
2. Me ya sa bakin karfe tsatsa?
Bakin karfe yana da ikon yin tsayayya da iskar iska mai iska - tsatsa juriya, kuma yana da ikon yin tsayayya da lalata a cikin matsakaici mai dauke da acid, alkali da gishiri, wato, juriya na lalata.Duk da haka, juriya na lalata na karfe ya bambanta da sinadaran sinadaran, yanayin juna, yanayin sabis da nau'in matsakaicin muhalli.
Bakin karfe siriri ne, mai ƙarfi kuma lafiyayyan barga chromium mai arzikin oxide fim (fim ɗin kariya) da aka kafa akan samansa don hana atom ɗin oxygen ci gaba da shiga da oxidize, da samun juriya na lalata.Da zarar fim ɗin ya ci gaba da lalacewa saboda wasu dalilai, ƙwayoyin oxygen a cikin iska ko ruwa za su ci gaba da kutsawa ko kuma atom ɗin ƙarfen da ke cikin ƙarfe zai ci gaba da rabuwa, ya zama sako-sako da ƙarfe, kuma saman karfen zai ci gaba da lalacewa.Akwai nau'i-nau'i da yawa na lalacewa ga wannan abin rufe fuska na fuskar, kuma waɗannan sun zama ruwan dare a cikin rayuwar yau da kullum:
1. Kurar da ke ɗauke da wasu abubuwa na ƙarfe ko haɗe-haɗe na ɓangarorin ƙarfe masu kama da juna ana adana su a saman bakin ƙarfe.A cikin iska mai danshi, condensate tsakanin abubuwan da aka makala da bakin karfe yana haɗa su zuwa cikin ƙaramin tantanin halitta, yana haifar da halayen electrochemical da lalata fim ɗin kariya, wanda ake kira lalatawar electrochemical.
2. Ruwan 'ya'yan itace (irin su kankana da kayan lambu, miyar miya da phlegm) suna manne da saman bakin karfe.A gaban ruwa da oxygen, suna samar da kwayoyin acid, wanda zai lalata saman karfe na dogon lokaci.
3. Ana manne da saman bakin karfe da sinadarin acid, alkali da gishiri (kamar alkali da ruwan alkali da gwajin feshin ruwan lemun tsami don ado bango) don haifar da lalata a cikin gida.4. A cikin gurɓataccen iska (yanayin da ke ɗauke da adadi mai yawa na sulfide, oxide da hydrogen oxide), lokacin da aka haɗu da ruwa mai laushi, sulfuric acid, acid nitric acid da acetic acid za su sami maki ruwa, wanda zai haifar da lalata sinadarai.
3. Yadda za a magance tsatsa spots a bakin karfe?
a) Hanyar kimiyya:
Yi amfani da manna tsintsiya ko fesa don taimakawa sassan da suka lalace don sake ƙetare da samar da fim ɗin chromium oxide don dawo da juriyar lalata.Bayan tsinkayar, yana da matukar mahimmanci a wanke da ruwa mai tsabta yadda ya kamata don cire duk wani gurɓataccen abu da ragowar acid.Bayan duk jiyya, yi amfani da kayan aikin goge goge don sake gogewa kuma a rufe da kakin zuma mai gogewa.Ga waɗanda ke da ƙananan tsatsa a cikin gida, ana iya amfani da cakuda 1: 1 na man fetur da man inji don shafe tsatsa da tsutsa mai tsabta.
b) Hanyar injina:
