Saxanka Kaarboon-ka-Aan Tayada Sare leh
Saxanka birta-la'aanta ah guud ahaan waa magaca guud ee saxanka birta ah iyo saxan birta u adkaysata aashitada.Waxay soo baxday bilowgii qarnigan.Horumarinta saxanka birta ah ayaa dhigay qalab muhiim ah iyo aasaas farsamo oo loogu talagalay horumarinta warshadaha casriga ah iyo horumarka sayniska iyo tignoolajiyada.Waxaa jira noocyo badan oo ah taarikada birta ah oo aan lahayn astaamo kala duwan.
Waxay si tartiib tartiib ah u sameysay dhowr qaybood oo geedi socodka horumarka.Marka loo eego qaab-dhismeedka, waxa loo qaybiyaa afar qaybood: austenitic ahama saxan, Martensitic ahama saxan (oo ay ku jiraan roobab adag saxan bir ahama), saxan bir ferritic ahama, iyo austenitic iyo ferritic duplex ahama birta saxan?
Marka loo eego ka kooban kiimikada ugu weyn ee saxan birta ah ama qaar ka mid ah walxaha sifo ee saxanka birta, waxa loo qaybiyaa chromium saxan bir ahama, chromium nickel saxan bir ahama, chromium nickel molybdenum saxan bir ahama, chromium-kaarboon-yar saxan bir ahama, molybdenum sare saxan bir ah, saxan bir ah oo nadiif ah oo sarreeya, iwm.
Marka loo eego sifooyinka waxqabadka iyo isticmaalka taarikada birta, waxay u kala qaybsan yihiin nitric acid saxan bir ah oo adkaysi u leh, sulfuric acid saxan birta birta u adkaysta, daxalka u adkaysta saxan bir ah, diiqad u adkaysata saxan bir ah, xoog sare oo saxan bir ah, iwm.
Sida laga soo xigtay sifooyinka functional of saxan birta ah, waxa loo qaybiyaa hooseeyo-heerkulka ahama, saxan bir aan magnetic, saxan bir ahama goynta bilaashka ah, superplastic saxan bir ahama, iwm Waqtigan xaadirka ah, habka caadiga ah loo isticmaalo kala soocidda waa in u kala saar saxanka birta iyadoo loo eegayo sifooyinka qaabdhismeedka birta, sifooyinka kiimikada ee saxanka birta iyo isku dhafka labada.Guud ahaan waxa loo kala qaybiyaa saxan bir ahama ah oo martensitic ah, saxan bir ah oo bir ah oo ferritic ah, saxan bir ah oo austenitic ah, saxan birta duplex iyo roobka oo adkeeya saxan bir ahama, ama saxan bir ah oo chromium ah iyo saxan bir aan lahayn nikkel.
Qalabka saxarada iyo warqadaha, kulaylka beddelka, qalabka farsamada, qalabka rinjiyeeynta, qalabka filimaanta, dhuumaha, alaabta dibadda ee dhismayaasha xeebaha, iwm.
Iska caabbinta daxalka ee birta aan fiicnayn waxay inta badan ku xiran tahay halabuurka daawaha (chromium, nickel, titanium, silicon, aluminium, manganese, iwm.) iyo qaab dhismeedka gudaha.
Marka loo eego habka diyaarinta, waxaa loo qaybin karaa duubitaan kulul iyo qabow qabow.Marka loo eego sifooyinka qaab-dhismeedka ee darajada birta, waxaa loo qaybin karaa 5 qaybood: Nooca Austenitic, nooca AUSTENITIC FERRITIC, nooca ferritic, nooca martensitic iyo nooca adkeynta roobabka.
Saxanka birta ah waxa uu leeyahay dusha siman, caag sare, adkaanta iyo xoogga farsamada, waana u adkaysta daxalka aashitada, gaaska alkaline, xalalka iyo warbaahinta kale.Waa nooc ka mid ah birta daawaha ah oo aan fududayn in miridhku ku jiro, laakiin gebi ahaanba ma aha miridhku.Saxanka birta ah ee birta ah waxay awood u leedahay inay iska caabiso daxalka guud ee la mid ah nikkel chromium alloy aan degganayn 304. Kuleyliyaha dheer ee heerkulka heerkulka chromium carbide wuxuu saameyn karaa iska caabbinta daxalka ee Alloys 321 iyo 347 ee warbaahinta adag ee adag.
Waxaa inta badan loo isticmaalaa codsiyada heerkulka sare.Codsiyada heerkulka sare waxay u baahan yihiin iska caabin dareen xoog leh si looga hortago daxalka intergranular heerkulka hoose.
Wixii birta ah ee la jeexjeexay, marka hore ka saar maqaarka madow leh ng-9-1 chemistry, iyo kuwa saliidda leh, marka hore ka saar saliidda nz-b dereasing king dareere, heerkulku waa 60 ~ 80 ℃, workpiece waxaa lagu laalaaday anode, Da hadda waa 20 ~ 15A / DM2, iyo cathode waa aluminium antimony lead (oo ay ku jiraan antimony 8%) Time: 1 ~ 10 daqiiqo, Polishing → biyo dhaqid → filim oo lagu xayuubiyay 5 ~ 8% hydrochloric acid (heerkulka qolka: 1 ~ 3 ilbiriqsi) → biyaha dhaqida → qalaji.
