Fikradda carbide sibidhka: walxo isku dhafan oo ay soo saartay birta budada ah oo ka kooban iskudhis bir celin ah (wejiga adag) iyo birta isku xidhan (wejiga isku xidhan).
Matrix-ka carbide sibidhka wuxuu ka kooban yahay laba qaybood: Qayb waa wejiga adag: Qaybta kale waa birta isku xidhka.
Marxaladda adagi waa carbide ee biraha kala-guurka ee miiska xilliyeed ee walxaha, sida tungsten carbide, carbide titanium, carbide tantalum, kuwaas oo aad u adag oo leh dhibic dhalaalaysa in ka badan 2000 ℃, qaar xitaa in ka badan 4000 ℃.Intaa waxaa dheer, nitrides birta kala guurka, borides, silicides sidoo kale waxay leeyihiin sifooyin la mid ah oo loo isticmaali karaa sida weji adag in carbide sibidhka.Joogitaanka marxaladda adag ayaa go'aamisa qallafsanaanta aadka u sarreeya iyo xirashada caabbinta daawaha.
Biraha isku xidha guud ahaan waa biraha kooxda birta, sida caadiga ah cobalt iyo nikkel.Soo saarista karbidhida sibidhka, budada alaabta ceeriin waxaa lagu doortaa cabbirka walxaha u dhexeeya 1 iyo 2 microns iyo heer sare oo nadiif ah.Alaabta ceeriin waxaa lagu qiyaasaa iyadoo loo eegayo saamiga ka kooban ee loo qoray, oo lagu daraa khamriga ama warbaahinta kale ee mashiinka kubbadda qoyan, qoyan qoyan, si ay si buuxda isugu qasan, la jajabiyo, la qalajiyo, la shaandheeyo oo lagu daraa dhuka ama xanjo iyo noocyada kale ee wax lagu dhejiyo. wakiilada, ka dibna la qalajiyey, shaandheyn oo la sameeyey isku dar ah.Dabadeed isku dar ah waa granulated, la riixay, oo kuleylinta meel u dhow barta dhalaalka ee birta xidhxidhan (1300 ~ 1500 ℃), wejiga adag iyo biraha xidhan waxay samayn doonaan daawaha eutectic ah.Ka dib qaboojinta, marxaladda adag ayaa loo qaybiyaa qulqulka ka kooban birta isku xiran waxayna si dhow ula xiriirtaa midba midka kale si uu u sameeyo mid adag.Adkeydka karbidhida sibidhka waxay kuxirantahay heerka adkaanta iyo cabirka hadhuudhka, ie mar kasta oo heerka adkaanta heerka sareeyo iyo inta uu le'eg yahay cabirka hadhuudhka, waa ay sii weynaataa engegnaanta.Adkaynta karbidhida sibidhka waxaa lagu go'aamiyaa birta isku xidhka ah, iyo marka ay sare u kacdo nuxurka birta isku xidhka ah, way sii badanaysaa xoogga foorarsiga.
Astaamaha aasaasiga ah ee carbide sibidhka:
1)Adayg sare, caabbinta xirashada sare
2) Module sare ee barti
3) Xoog cadaadis sare leh
4) Degganaanshiyo kiimikaad oo wanaagsan (asiidh, alkali, iska caabin oksaydh heerkul sare ah)
5) adkaanta saameyn hoose
6) Kordhinta hoose ee balaadhinta, kulaylka iyo korantada oo la mid ah birta iyo alloyskeeda
Codsiyada carbide sibidhka: Qalabka casriga ah ee casriga ah, xidho walxaha adkaysi u leh, heerkulka sare iyo alaabta u adkaysata daxalka.
Faa'iidooyinka qalabka carbide (marka la barbar dhigo birta alloy):
1) Si aad ah, daraasiin ama xitaa boqolaal jeer si loo hagaajiyo nolosha qalabka.
Nolosha qalabka birta ayaa la kordhin karaa 5-80 jeer, nolosha gage ayaa kordhay 20-150 jeer, nolosha caaryada ayaa kordhay 50-100 jeer.
2) Kordhi xawaaraha goynta birta iyo xawaaraha qodista qolof ah si xad dhaaf ah iyo tobanaan jeer.
3) Hagaajinta saxnaanta cabbirka iyo dhamaystirka dusha sare ee qaybaha mashiinka.
4) Waxaa suurtagal ah in lagu farsameeyo qalabka mashiinka adag sida daawaynta kulaylka u adkeysata, daawaynta saamaynta iyo birta adag ee adag, kuwaas oo ay adag tahay in lagu farsameeyo birta xawaaraha sare leh.
5)Waxay samayn kartaa qaybo u adkaysta daxalka ama heerkulka sare u adkaysta qaybo ka mid ah xidhashada, sidaas darteed hagaajinta saxda ah iyo nolosha mashiinada iyo qalabka qaarkood.
Kala soocida Carbide sibidhka:
1. WC-Co (tungsten drill) nooca daawaha: oo ka kooban tungsten carbide iyo cobalt.Mararka qaarkood qalabka wax lagu gooyo (mararka qaarkood sidoo kale qalabka rasaasta) ku dar 2% ama ka yar carbide kale (tantalum carbide, niobium carbide, vanadium carbide, iwm) sida daroogo.Cobalt sare: 20-30%, cobalt dhexdhexaad ah: 10-15%, cobalt hoose: 3-8%
2. WC-TiC-Co (tungsten-iron-cobalt) -nooca daawaha.
Alloy titanium hoose:4-6% TiC, 9-15% Co
Daawaha Chin Dhexdhexaad: 10-20% TiC, 6-8% Co
Daawaha sare ee titanium: 25-40% TiC, 4-6% Co
3.WC-TiC-TaC(NbC) -Co alloys
Daawaynta WC-TiC-Co waxay leedahay iska caabin oksaydh heerkul sare oo ka fiican iyo sidoo kale qaska kulaylka ka fiican, sidaas darteed badiyaa waxay leedahay nolosha aaladda sare.TiC:5-15%, TaC(NbC):2-10%, Co:5-15%, inta soo hartay waa WC.
4. Carbid sibidhed bir ah: oo ka kooban tungsten carbide ama carbide titanium iyo birta kaarboon ama birta daawaha.
5. Titanium carbide alloy ku salaysan: oo ka kooban kaarboon marka loo eego titanium, birta nikkel iyo birta molybdenum ama molybdenum carbide (MoC).Wadarta waxa ku jira nikkel iyo molybdenum inta badan waa 20-30%.
Carbide waxaa loo isticmaali karaa in lagu sameeyo burka rotary, daab CNC, wax gooya, mindiyo wareeg ah, mindiyo jeexjeexa, garbaha alwaax, daab miinshaar, ulaha carbide, iwm.
