1. Dab tsi yog qhov tseem ceeb ntawm tus kheej thiab tus thawj coj ntawm GH3030?
GH3030 yog feem ntau teev npe ntawm lwm qhov "GH" series alloys. Dab tsi yog nws cov tub ntxhais xeeb core, thiab nws ua li cas nws tsis pom meej los ntawm cov muaj zog ntau xws li GH4169?
Gh3030 yog cov khoom -}}}}} daws teeb meem noickel {2} buad supalloy. Nws lub npe thoob ntiaj teb ua lag luam yog Nimonic 75 ™. Qhov kev faib tawm no yog qhov tseem ceeb thiab tam sim ntawd teeb tsa nws sib nrug ntawm alloys zoo li GH4169.
Qhov tseem ceeb sib txawv lus dag nyob rau hauv lub zog expagchism:
GH4169: ib qho dej nag: - Harden Alloy, ntxiv dag zog los ntawm cov ntim siab ntawm γ '' thiab γ 'theem. Qhov no muab nws muaj zog heev li cas tab sis ntxiv cov kev nyuaj ntxiv nrog kev ua haujlwm kub.
GH303030: ib qho khoom khov kho -}} daws cov tshuaj tiv thaiv ntxiv. Nws derives nws lub zog tsis yog los ntawm kev siv hluav taws xob, tab sis los ntawm cov atoms ntawm alloy, hlau) yaj ncaj qha rau lub ntsej muag ci ntsa iab thiab cuam tshuam nrog kev tshem tawm lub crystal.
Tus thawj coj ntawm GH3030 tsis yog nws qhov kawg tensile lub zog, tab sis nws zoo oxidation tsis kam, zoo formability, thiab siab ua lag luam. Nws yog tsim rau ntev - kev pab cuam hauv oxidizing tsis kam rau 800- ib puag ncig yog qhov tseem ceeb dua li lub zog raw.
2. Dab tsi yog Metallurgical hauv paus rau nws qhov siab- kub ua haujlwm thiab ruaj khov?
Cov tshuaj lom neeg muaj pes tsawg leeg thiab cov microstructure yooj yim ntawm GH3030 pab tau nws txoj kev ua tau zoo?
Qhov metallurgy ntawm GH3030 yog yooj yim yooj yim thiab siv tau rau nws lub hom phiaj npaj. Nws muaj pes tsawg leeg yog ua kom haum rau kev tiv thaiv ib puag ncig thiab microstration ruaj khov.
Lub npib tsib xee - chromium matrix (~ 70% ni, ~ 20% cr): cov ntawv no cov tub ntxhais ntawm alloy.
Nickel muab lub ruaj khov, ducast, anustenic (ntsej muag {- chaw sau cubic) lub hauv paus uas khaws nws cov qauv ntawm qhov kub.
Chromium yog tus yuam sij rau oxidation tsis kam. Thaum muaj kub, nws ua qhov ntom ntom, ua rau cov txheej txheem, thiab txuas ntxiv cov txheej ntawm chromium oxide (cr₂o₃) rau saum npoo. Cov txheej no ua raws li qhov muaj txiaj ntsig zoo, tiv thaiv cov pa oxygen los ntawm cov cua los ntawm kev nkag mus thiab oxidizing lub hauv qab hlau.
Cov teeb meem daws tau cov tshuaj tiv thaiv ntxiv: cov ntsiab lus xws li Titanium thiab Aluminium yog tam sim no nyob rau hauv me me. Thaum tsis muaj txaus los ua kom muaj kev sib zog ua tsaug rau qhov tawv (zoo li hauv Nimonic 80a lossis 90), lawv pab kom txhim kho qhov ruaj khov ntawm cov khoom tiv thaiv oxide.
Microstration tsim: Lub -}}}}}}}} kev ruaj khov. Nws tsis yauv theem kev hloov pauv lossis cov nag lossis daus ntawm cov kab hauv qab theem nrab (zoo li sigma lossis era}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}. Qhov no zam cov teeb meem embrittlement uas tuaj yeem ua rau muaj kev nyuaj ntxiv. Nws ruaj khov yog nws cov cuab tam zoo tshaj plaws rau ntev - daim ntawv thov lub neej.
3. Hauv kev siv tshwj xeeb yog GH3030 qhov kev xaiv uas nyiam tshaj plaws?
Muab nws cov cuab yeej tshwj xeeb, qhov twg yog GH3030 feem ntau thiab siv tau zoo?
Gh3030 yog cov khoom siv ntawm kev xaiv hauv high - qhov kev siv kub, thiab qhov uas muaj kev txhawj xeeb tshaj plaws yog qhov kev txhawj xeeb thawj. Nws thawj qhov chaw yog aerospace thiab cua sov kev lag luam.
Aerospace & Dav hlau tshuab:
Cheebtsam: Kev sib txuas sib xyaw Chamber, cov nplaim hluav taws, cov khoom sib xyaw ua ke, thiab kub {{} pa cua tshuab pa.
Vim li cas Gh3030? Hauv kev sib txuas ua ke, cov khoom siv tau ncaj qha rau cov roj kub. Thaum cov qib kev ntxhov siab muaj qhov nruab nrab, lub thermal cycling thiab oxidizing ib puag ncig yog huab. GH3030's Zoo Oxidation Resplations Tiv thaiv hlawv {}}}}}}}}}}}}}}
Kev lag luam cua sov thiab kev kho cua sov rhuab:
Cheebtsam: pob tawb kho cua sov, cua sov lub pob tawb, rauv muffles, radiant tubes, thiab thermocouple sheaths.
Vim li cas Gh3030? Nws muab kev ua tau zoo heev ntawm kev ua tau zoo thiab tus nqi rau cov khoom siv uas yuav tsum ua haujlwm kom dhau mus tsis muaj qhov kub thiab tsis muaj oxidation lossis distortion.
Lub zog tiam:
Cheebtsam: Cov thermal teeb meem sib xyaw ua ke, cov nplhaib sib khi, thiab cov tub dai hauv cov pa roj av.
Hauv tag nrho cov xwm txheej no, GH3030 yog xaiv thaum tus qauv stainless hlau zoo li 310s yog nyob ntawm lawv cov kev ua tau zoo thiab kev ua haujlwm zoo li GH4169 tsis yog muaj kev ntxhov siab.
4. Dab tsi yog qhov tseem ceeb ntawm kev tsim khoom thiab muag saib GH3030 kav?
Cov tawv nqaij - kev daws qhov ntawm Gh3030 cuam tshuam nws cov chaw tsim khoom, tshwj xeeb yog tsim cov kav dej thiab cov leeg?
Qhov no yog ib qho ntawm GH3030's Standout zoo. Nws ib qho tib yam -}}} Cov qauv daws teeb meem ua rau nws muaj kev kub ntxhov ntau dua li cov nag lossis yooj yim}}} HARDENDED superalloys.
Txias thiab kub thawj: GH3030 muaj cov qauv ua kom zoo thiab tuaj yeem tsim kom muaj cov duab ua ke, suav nrog cov kav dej, siv ob qho tib si txias thiab kub ua haujlwm. Nws cov haujlwm ua haujlwm hnyav yog qis dua li ntawm ntau lwm cov superalloys, tso cai rau ntau yam kev tawm tsam ntau ntawm cov kauj ruam nruab nrab.
Vuam: Gh3030 yog cais raws li muaj kev sib luag heev. Nws tuaj yeem welded siv cov txheej txheem sib xws li roj tungsten arc vuam (GMaw / Mig) thiab roj Weld kev kho kom sov kom ua rau muaj kev kub ntxhov nag.
Muab tub rog sib xyaw ua ke: qhov sib xyaw sib xyaw ua ke (piv txwv li, GH3030 xaim) lossis ib qho siab dua ib qho zoo li ernicr-3 feem ntau siv.
Kev Ceev Faj: Thawj qhov kev txhawj xeeb tseem tsis yog tshaj tawm - Weld kev laus, tab sis kev tiv thaiv lub chaw weld kev tawm tsam oxidation reedored yog rov qab los. Ib qho kev daws teeb meem tom qab vuam yog qee zaum ua rau rov ua kom tsis muaj cov nplai ntawm cov cua sov {{}}} cuam tshuam cheeb tsam.
Machining: thaum tseem xav tau ntau lub zog thiab saib xyuas dua li cov hlau, GH3030 yog ntau dua yooj yim dua "Gummy" lossis ua haujlwm siab} Hardening Alloys zoo li GH4169. Nws ntau twv ua ntej tshaj tawm kev tsim kho thiab kev ua haujlwm hnyav ua haujlwm kom muaj ntau dua cov tshuab hloov pauv ruaj khov.
5. Dab tsi yog cov ciaj ciam thiab cov kev txwv ntawm GH3030?
Dab tsi yog qhov tseem ceeb txwv thiab tsis ua hauj lwm hom ntawm GH3030 uas cov kws ua haujlwm yuav tsum xav txog?
Nkag siab rau thaj tsam ntawm GH3030 yog qhov tseem ceeb los tiv thaiv nws cov kev ua txhaum cai thiab ua kom muaj kev pab cuam.
Lub zog txwv (thawj kev txwv): Gh3030 yuav tsum tsis txhob siv nyob rau hauv high- kev siv kev ntxhov siab. Nws cov txiaj ntsig thiab lub zog sib txawv yog qhov qis dua li cov nag lossis daus- Cov khoom siv tsis yooj yim li GH4169, tshwj xeeb tshaj yog nyob rau qhov kub thiab txias saum toj siab tshaj 600 ° C. Siv nws rau cov txheej txheem turbine zoo nkauj lossis ib tus ncej tseem ceeb yuav ua rau muaj kev tiv thaiv sai sai.
Thaum lub sij hawm kub thiab txias rau load - Cov kabmob oxidation: ° C, nws load - bearing bearing medly kom kub nce. Rau cov txheej txheem sib xyaw, nws cov kev pab cuam kub nyob rau hauv cov kev ntxhov siab tseem ceeb yog qhov qis dua, feem ntau nyob rau hauv 700-800 ° C ntau ntau. Kev tsim tsim yuav tsum yog ua raws nws cov ntaub ntawv nkag thiab tsis muaj zog, tsis yog nws cov oxidation tsis kam.
Txwv ib puag ncig cov kev txwv:
Sulfidation: thaum zoo heev hauv oxidizing ib puag ncig, nws cov ntsiab lus nickel ua rau nws raug kev tawm tsam kom txo qis sulfidizing.
Chloride nres: Zoo li ntau npib tsib xee {{chromium alloys, nws tuaj yeem yog kev ntxhov siab citting rau hauv cov xwm txheej tshwj xeeb.
Tus nqi vs. Kev Ua Haujlwm: Rau kev thov uas oxidation qhov kawg tsis kam ntawm GH2747 (nrog 35% CR) yuav tsum muaj, GH3030 yuav tsis muaj txaus. Hloov siab, rau qis {{5 5}} sov daim ntawv thov, ib qho yooj yim stainless hlau li 321 lossis 310s yog tus nqi ntau dua {8}- kev xaiv zoo.
Xaus: Gh3030 yog "Workhorse" khoom -} daws superalloy. Nws tsis yog qhov muaj zog tshaj plaws, tab sis nws yog txhim khu kev qha, ruaj khov, thiab siv tau heev. Nws ua rau zoo nyob rau hauv high - kub, qis}}} kev tsim tawm kev tsim tawm nyob rau qhov twg yog qhov yuav tsum tau ua tiav.
