Inconel 625: "Tag nrho cov kev sib tw" hauv qhov kub thiab txias thiab thaj chaw muaj huab cua
Inconel 625: "Tag nrho cov kev sib tw" hauv qhov kub thiab txias thiab thaj chaw muaj huab cua
Lub hauv paus rau phau ntawv
Inconel 625 (Tsis yog N06625) yog ib tug npib tsib xee-} {}} Cov lus qhia ntawm nws cov yam ntxwv ua tau zoo, cov ntawv thov raug thiab yav tom ntej peev xwm .
I {.}}}} kev siv tshuaj lom neeg thiab kev ua haujlwm tseem ceeb
1.} Alloy Tsim
Qhov muaj pes tsawg leeg ntawm inconel 625 yog:
Npib tsib xee (ni): ntau dua los yog sib npaug rau 58% (Matrix, muab kev kub ntxhov siab)
Chromium (CR): {20-23% (anti-oxidation thiab corrosion tsis kam)
Molybdenum (mo): {{8-10% (txhim kho kom tsis txhob pitting thiab crevice corrosion)
Niobium (NB) + TANTALUM (TA): {}}}}}}}}}% (inhibiting mines heev qoob loo embrittlement)
2.} Cov Ntsiab Lus Tseem Ceeb
Corrosion Kuj:
Tiv taus txoj kev tawm tsam muaj zog xws li Chlorides, sulfuric acid, phosphoric acid;
Kev ua tau zoo heev hauv hiav txwv thiab acidic roj thiab roj ib puag ncig (corrosion tus nqi<0.025mm/year).
Kev Kub Siab Tshaj:
Kev siv ntev ntev: -196℃rau 980 degree;
Tensile lub zog tseem muaj ntau dua lossis sib npaug rau 170 MPa ntawm 980 degree.
Ua kev hloov kho tau:
Txhawb kev vuam (tig, laser vuam), forging, adcessitive manufacturing (3D printing) thiab lwm yam kev.
Ii {.} Khomob Kev Pabcuam
1.} Aerospace
Lub dav hlau cav cov khoom siv: combuster Chamber liner, Turbine Foob nplhaib (tiv taus cov pa roj kub (cua sov roj corrosion);
Rocket Expulsion System: Roj pipeline, valve (tiv taus kua oxygen / kua hydrogen tsawg kub ib puag ncig) .
2. marine engineering
Cov khoom sib sib zog nqus-hiav txwv
Desalination System: Evaporator Pipeline (tiv taus cov dej ntsev kom haum) .
3. lub zog thiab tshuaj lom neeg
Nuclear Reactor: Tswj Rod Kev Qhia Tube (Rauv thiab cua sov dej corrosion);
Cov Khoom Siv Petrochemical: Flue Roj Desulfurization Ntaus, Acid Gas Access Chav .
4. tawm teb
Kev Luam Ntawv 3D: Siv los tsim cov complex rab nyuj sib xyaw (xws li aviation radiators);
Hydrogen Zog Cia thiab Tsheb Thauj Mus Los: Cov Kev Lag Luam Hydrogen Cia Lub Tho kaub Streling (Anti-Hydrogen embrittlement) .
Iii {.} Qhov zoo thiab kev lag luam kev sib tw
1. muaj peev xwm hloov cov ntaub ntawv tsoos
Piv nrog 304 stainless hlau, lub neej pabcuam hauv cov pa hluav taws kub nyob ib puag ncig yog nce los ntawm {1} {1 zaug;
Tus nqi yog 20% qis dua Hastelloy c -276}}, thiab kev ua haujlwm vuam yog qhov zoo dua.
2. txheej txheem tshiab rooj plaub
Ntxiv cov khoom lag luam: Siv laser cladding (Ded) thev naus laus zis thev naus laus zis los txo cov weld tsis muaj zog; Nto cladding: cladding inconel 625 ntawm cov pa roj carbon staystrate, noj rau hauv tus account ob tus nqi thiab kev ua haujlwm .
Plaub, kev ceev faj rau kev siv
Cov txheej txheem vuam: gtaw (Argon arc vuam)}}}}}} kub vuam (tsawg dua los yog sib npaug rau 150 degree);
Kev Kho Cua Sov: Kev Kho Mob ({1150-1200 degree) tuaj yeem tshem tawm kev ntxhov siab nyob rau ntawm {2}℃(los tiv thaiv σ theem los nag);
Ua haujlwm hnyav: nws pom zoo kom siv cov khoom noj nrawm nrawm thiab muaj cov cuab yeej siv hluav taws xob tsis zoo (xws li cov pa roj ceramed cemented carbide) thaum txiav .
Tsib, kev lag luam qauv thiab yav tom ntej kev cia siab
Nrog rau kev txhim kho ntawm lub zog huv (hydrogen zog, lub zog nuclear) thiab kev ua haujlwm thoob ntiaj teb raws li cov tub rog hauv ntiaj teb no kom ntau dua 40%.
