Dab tsi yog lwm txoj kev xaiv rau inconel 625?
Peb ua ib qho tob tob ntawm ob qhov kev ua tau zoo nickel alloys thiab piv lawv cov kev qhia tshwj xeeb thiab kev siv.
Thaum koj tab tom nrhiav rau cov khoom zoo rau koj qhov project tom ntej, kev ua haujlwm ntawm kev ua tau zoo npib yuav yog qhov koj xav tau. Txawm li cas los xij, muaj cov qib xaiv los xaiv los ntawm tsev neeg tsis raug, ib qho uas yuav ua tau raws li qhov koj xav tau.
Lub almoy inconoy yog inconel alloy 625, uas yog ib qho ntawm feem ntau cov khoom siv feem ntau tsim. Nrog nws zoo corrosion tsis kam thiab lub zog siab, nws haum rau ntau cov ntawv thov hla ntau yam ntawm kev lag luam. Nws yog cov khoom siv nrov heev uas tuaj yeem daws ntau yam teeb meem rau cov cuab yeej tsim qauv. Qhov tseeb hais tias nws tau ua li ntawd rau ntau dua 50 xyoo thiab tseem siv tau yog ib qho uas siv yog cov lus pov thawj rau nws qhov zoo.
Txawm li cas los xij, yog lub zog siab yog qhov kev txiav txim siab thawj, Inconel Alloy 725 tej zaum yuav yog qhov zoo dua. Nws zoo ib yam li incoy alloy 625, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm corrosion tsis kam. Txawm li cas los xij, muaj qhov sib txawv tseem ceeb ntawm ob, uas yuav cuam tshuam rau kev txiav txim siab cov khoom uas siv.
Txhawm rau pab koj nkag siab txog qhov sib txawv thiab sib txawv ntawm ob cov ntaub ntawv tshwj xeeb, peb tau muab piv rau lawv cov yam ntxwv tseem ceeb thiab cov khoom.
Muaj pestrosition sib txawv
Qhov laj thawj incel 625 Alloy muaj xws li ntau ntau ntawm cov khoom xav tau yog vim nws cov cim muaj pes tsawg leeg. Nws yog lub nickel siab, nrog tsawg kawg 58% npib tsib xee nyob rau hauv kev sib xyaw. Nws tseem muaj chromium (20-23%) thiab molybdenum (}%), nrog rau ntxiv niobium (3. {5}}. 15%).
Niobium sib xyaw nrog molybdenum thiab distorts the Atomic matrox ntawm alloy, ua rau muaj kev mob siab rau qhov tsis muaj peev xwm ua kom muaj kev pab cuam kub. Qhov loj ntawm npib tsib xee thiab chromium ua ke muab cov khoom zoo kawg corrosion, cia nws los tiv taus cov khoom muaj xeb heev thiab cov chaw ib puag ncig.
Inconel 725 Alloy Shares ntau yam ntawm tib lub chaw ua yeeb yam - qhov tseeb, superficially, lawv yuav luag zoo ib yam. Nws khaws cov nyiaj npib ntau (55-59%) thiab chromium ({}. 5%}. 50%). Raws li qhov tshwm sim, cov khoom muaj kev sib xws corrosion tsis kam rau inconel 625 Alloy, ua rau nws haum rau ntau qhov kev xeb ntau puag ncig.
Txawm li cas los xij, muaj kev sib txawv me ntsis sib txawv ntawm cov muaj kev sib xyaw tag nrho ntawm ob cov ntaub ntawv. Inconel 625 alloy muaj cov nyiaj me me ntawm cobalt thiab nyiaj, uas tsis muaj nyob hauv Inconel 725 Alloy. Inconel 725 alloy muaj qhov siab dua titanium cov ntsiab lus ({}}. 4% piv rau lub 5%. Cov pob sib ntxiv thiab sib txawv ntxiv rau kev tsim cov micro-precipitates thaum tshav kub kub, uas ua rau muaj zog siab dua rau inconel 725 alloy.
Sib piv lub zog
Inconel 625 alloy yog ib lub nickel muaj zog. Raws li tau hais yav tas los, qhov no yog vim muaj kev cuam tshuam ntawm nws muaj pes tsawg leeg thiab ntxiv ntawm niobium. Qhov sib xyaw ntawm niobium nrog molybdenum tsim cov nyhuv tawv heev uas tshem tawm qhov kev xav tau ntawm kev kho kom muaj nag lossis daus. Rau ntau daim ntawv thov, qhov xam tau lub zog ntawm cov khoom no yog ntau tshaj li qhov txaus. Nws tseem ua kom zoo dua ntau lwm cov nickel alloys hauv thaj chaw no.
Txawm li cas los xij, qee zaum lub zog siab dua, tab sis tsis yog nyob rau cov nuj nqis ntawm kev tiv thaiv corrosion zoo heev. Inconel alloy 625 tau nthuav tawm thiab lag luam ua cov khoom siv hluav taws xob muaj zog tag nrho. Nws tau pom tias nws muaj cov khoom muaj hnub nyoog uas nws tau ua ntau yam kev sim ua tiav raws sijhawm los kawm nws cov teebmeem. Nws tau tshawb pom tias qhov sib ntxiv ntawm titanium tseem hloov kho lub hnub nyoog uas ua rau tawv tawv. Qhov no coj mus rau kev tsim cov alloy tshiab - peb hu nws tsis tau Incely 725 (Kawm ntxiv txog nws hauv cov ncauj lus ncauj lus ntxaws ntxaws no).
Hnub nyoog-hardened inconel 725 yog kwv yees li anneoy ecoycel 725 Lub zog no tuaj yeem muab rau cov khoom loj, tsis muaj kev sib txawv ntawm cov khoom uas tsis tuaj yeem txhawb nqa los ntawm kev ua haujlwm txias.
Cov ntawv thov sib txawv
Cov khoom twg yog xaiv feem ntau yog nyob ntawm qhov kawg npaj kev thov ntawm alloy.
Inconel 625 Alloy yog ntau yam thiab yog siv nyob rau hauv ntau ntawm kev lag luam. Piv txwv li, nws feem ntau yog siv nyob rau hauv cov ntawv thov seaterater vim nws txoj kev tiv thaiv kom tsis txhob muaj corrosion hauv nroog xws li pitting thiab crevice corrosion. Nws tseem tiv taus chloride ion muaj kev ntxhov siab corrosion. Yog li ntawd, nws cov ntawv thov suav nrog GARUSPAIL PRANKERER, Submarine Expulation Pipes, thiab submarine Kev sib txuas lus cable Juanjecting.
Nws tseem yog cov khoom siv ntawm kev xaiv hauv Aerospace kev lag luam, qhov uas nws lub zog siab, nkees nkees thiab weldability zoo nkauj yog nws cov peev txheej zoo tshaj plaws. Qhov no suav nrog kev siv cov dav hlau devwork, cav tso cov tshuab, thiab cov roj. Lwm cov kev siv kev lag luam kev lag luam suav nrog Nuclear Reactor Cheebtsam thiab yog siv dav siv hauv cov nroj tsuag ua haujlwm.
Inconel 725 Alloy tseem tseem siv tau dav hauv ntau qhov kev lag luam, tab sis thaum nws lub zog heev yog qhov yuav tsum tau ua, cov neeg yuav xaiv nws tsis suav 625 alloy. Piv txwv li, hauv kev sib sau ua ke, qhov uas tau txais kev tiv thaiv corrosive, Inconel pob qij txha, sab hnab pob txha caj dab, thiab polished bore cov throutets, thiab poluthed bore cov throutets, ntawm lwm yam.
Zoo li Inconel 625 Alloy, Inconel 725 Alloy tseem siv hauv kev lag luam marine. Ntawm no, nws yog qhov kev xaiv zoo rau cov khoom xws li high-lub zog tau xav tau yam tsis muaj kev txau, pitting, lossis kev sib ntxub.
Yog tias koj xav paub txog kev kawm ntxiv txog Inconel 625 Alloy lossis Inconel 725 Alloy lossis lwm tus tswv cuab ntawm peb pab pawg muag khoom niaj hnub no.
