Raws li cov txheej txheem npaj, nws tuaj yeem muab faib ua deformed superalloy, casting superalloy thiab hmoov metallurgy superalloy. Raws li txoj kev txhawb zog, muaj cov khoom khov kho hom kev txhawb zog, nag lossis daus hom kev txhawb zog, oxide dispersion hom kev txhawb zog thiab fiber hom kev txhawb zog. Cov hlau kub siab feem ntau yog siv rau hauv kev tsim cov khoom kub siab xws li turbine blades, guide vanes, turbine discs, high-pressure compressor discs thiab combustion chambers rau aviation, naval thiab industrial gas turbines, thiab kuj siv rau hauv kev tsim cov tsheb aerospace, rocket engines, nuclear reactors, petrochemical khoom siv thiab Thee hloov pauv thiab lwm yam khoom siv hloov pauv zog.

daim ntawv thov khoom siv

5J1480 thermal bimetal 5J1480 precision alloy 5J1480 superalloy hlau-nickel alloy superalloy yog hais txog ib hom khoom siv hlau raws li hlau, nickel thiab cobalt, uas tuaj yeem ua haujlwm ntev ntawm qhov kub siab tshaj 600 ℃ thiab nyob rau hauv qee qhov kev ntxhov siab; thiab muaj lub zog kub zoo heev, zoo oxidation tsis kam thiab corrosion tsis kam, zoo qaug zog, tawg toughness thiab lwm yam khoom tiav. Lub superalloy yog ib qho austenite qauv, uas muaj kev ruaj ntseg zoo thiab kev pabcuam kev ntseeg siab ntawm ntau yam kub.

Raws li cov yam ntxwv kev ua tau zoo saum toj no, thiab qib siab ntawm kev sib xyaw ntawm cov superalloys, tseem hu ua "super alloys", yog cov khoom siv tseem ceeb uas siv dav hauv kev tsav dav hlau, aerospace, roj av, kev lag luam tshuaj lom neeg, thiab nkoj. Raws li cov ntsiab lus matrix, superalloys raug muab faib ua hlau, nickel-based, cobalt-based thiab lwm yam superalloys. Qhov kub ntawm cov hlau kub siab feem ntau tsuas yog ncav cuag 750 ~ 780 ° C. Rau cov khoom siv tiv taus cua sov siv ntawm qhov kub siab dua, nickel-based thiab refractory hlau-based alloys siv. Nickel-based superalloys nyob hauv txoj haujlwm tshwj xeeb thiab tseem ceeb hauv tag nrho cov teb ntawm superalloys. Lawv siv dav los tsim cov khoom kub tshaj plaws ntawm cov cav dav hlau dav hlau thiab ntau yam roj turbines kev lag luam. Yog tias lub zog ruaj khov ntawm 150MPA-100H siv ua tus qauv, qhov kub siab tshaj plaws uas cov hlau nickel tuaj yeem tiv taus yog >1100 ° C, thaum cov hlau nickel yog li 950 ° C, thiab cov hlau ua los ntawm hlau yog <850 ° C, uas yog, cov hlau nickel yog siab dua los ntawm 150 ° C txog li 250 ° C. Yog li tib neeg hu cov hlau nickel ua lub plawv ntawm lub cav. Tam sim no, hauv cov cav siab heev, cov hlau nickel suav rau ib nrab ntawm tag nrho qhov hnyav. Tsis yog tsuas yog cov hniav turbine thiab cov chav sib txuas xwb, tab sis kuj tseem muaj cov turbine disks thiab txawm tias cov theem kawg ntawm cov hniav compressor tau pib siv cov hlau nickel. Piv nrog cov hlau hlau, qhov zoo ntawm cov hlau nickel yog: qhov kub ua haujlwm siab dua, cov qauv ruaj khov, cov theem tsis muaj teeb meem thiab kev tiv taus siab rau oxidation thiab corrosion. Piv nrog cov hlau cobalt, cov hlau nickel tuaj yeem ua haujlwm hauv qab qhov kub thiab kev ntxhov siab ntau dua, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm cov hniav txav mus los.

5J1480 thermal bimetal 5J1480 precision alloy 5J1480 superalloy Hlau-nickel alloy Cov txiaj ntsig saum toj no ntawm nickel alloy muaj feem cuam tshuam nrog qee qhov ntawm nws cov khoom zoo heev. Nickel yog lub ntsej muag-centered cubic qauv nrog ib tug heev

Ruaj khov, tsis muaj kev hloov pauv allotropic los ntawm chav tsev kub mus rau qhov kub siab; qhov no tseem ceeb heev rau kev xaiv ua cov khoom siv matrix. Nws paub zoo tias cov qauv austenitic muaj ntau qhov zoo dua li cov qauv ferrite.

Nickel muaj kev ruaj khov tshuaj lom neeg siab, tsis tshua oxidizes hauv qab 500 degrees, thiab tsis cuam tshuam los ntawm cua sov, dej thiab qee cov kua ntsev hauv tsev kawm ntawv kub. Nickel yaj qeeb qeeb hauv sulfuric acid thiab hydrochloric acid, tab sis sai sai hauv nitric acid.

Nickel muaj peev xwm ua tau zoo heev, thiab txawm tias ntxiv ntau tshaj kaum hom alloying elements tsis tshwm sim cov theem phom sij, uas muab cov peev xwm rau kev txhim kho ntau yam khoom ntawm nickel.

Txawm hais tias cov khoom siv kho tshuab ntawm cov nickel ntshiab tsis muaj zog, nws cov yas zoo heev, tshwj xeeb tshaj yog thaum kub tsawg, cov yas tsis hloov pauv ntau.

Nta thiab siv: qhov kub nruab nrab rhiab heev thiab siab resistivity. Thermal sensor hauv kev ntsuas kub nruab nrab thiab cov khoom siv tswj tsis siv neeg
