Cov yam ntxwv ntawm Nickel alloys
Dab tsi ua rau npib tsib xee?
Pom tseeb, cov khoom siv uas nquag muaj nyob hauv txhua nickel alloys yog ... npib tsib xee. Qhov ruaj khov hlau coj mus rau cov kev sib xyaw ua xeb, oxidation thiab qhov kub ua hauj lwm sib xyaw ua ke nrog qib siab ntawm kev ua siab loj thiab muaj peev xwm. Nws tsis muaj qhov xav tau uas Nickel alloys yog qhov kev xaiv Stalwart thoob plaws ntau yam kev lag luam thiab cov haujlwm. Qhov tseeb, nws tau kwv yees xyoo ntawd rau xyoo, 90% ntawm txhua tus Nickel muag tau yuav tshwj xeeb yog ua rau cov alloys.
Nickel alloys tuaj yeem ua rau ntau yam sib txawv, txhua tus muab nws tus kheej cov txiaj ntsig tshwj xeeb. Lawv ua rau cov khoom siv sib dua, ntev dua, corrosion resistant, thiab muaj zog txaus rau cov ntawv thov nyuaj tshaj plaws.
Nickel thiab Nickel alloys yog cov hlau tsis muaj nrog siab lub zog thiab tawv, zoo heev corrosion, thiab kev nce qib kub. Cov khoom lag luam sib txawv ua ke ntawm kev muaj pes tsawg leeg, qib kawm, cov qauv, qhov ntev, thiab cov yam ntxwv. Kev lag luam ntshiab, tsis muaj tseeb, lossis cov npib tsib tsawg heev tsis muaj lossis tsuas muaj tsawg tsawg ntawm cov khoom siv. Los ntawm kev sib piv, Nickel alloys muaj cov txiaj ntsig tseem ceeb ntawm cov khoom ntxiv lossis cov ntawv pov tseg. Clad lossis Bimetal Stock muaj ob qho sib txawv uas tau sib raug zoo ua ke. Hlau Matrix Composites muaj cov composite lossis alloy matoy lossis alloy matrouse tau ntim nrog, cov roj av, cov lus tseem ceeb, lossis ntaub npuag. Lwm yam tsis muaj cai, tshwj xeeb thiab cov kab nickel kuj muaj. Cov ntaub ntawv no feem ntau yog raws li cov txheej txheem alloy, siv cov cuab yeej siv ua haujlwm tshiab, lossis muaj cov khoom siv rau cov ntawv thov tshwj xeeb.
Ntau npib tsib xee thiab Nickel alloys tau raws li cov qauv hauv tebchaws Asmeskas, cov koom haum kev sib tham (SAE), thiab hlau lag luam kev sib txawv xws li Asmeskas Hlau thiab Hlau Lub Koom Haum (AISI). Cov haujlwm tsis yog cov hlau thiab alloys ib tsab ntawv ua ntej thiab tsib tus lej. Nickel thiab Nickel alloys muaj rau cov tsis muaj n qeb thiab muaj cov qauv tsim xws li tsis ua N02200. Lwm cov qauv rau npib tsib xee thiab nickel alloys muaj cov qib, European|QQ thiab QQS yog siv los xaiv cov khoom lag luam me me.
Xaiv npib tsib xee thiab nickel alloys yuav tsum tau tsom xam ntawm qhov ntev, cov txheej txheem ntau lawm, thiab ua tau zoo. Sab nraud inch (OD), sab hauv lub taub (ID), tag nrho cov ntev, thiab tag nrho cov tuab yog qhov ntev. Cov ntaub ntawv feem ntau tau cam, wrought, extruded, forged, txias, txias, kub-polled, lossis tsim los ntawm kev cog lus hmoov hlau los yog alloys. Kev ua tau zoo nta rau npib tsib xee thiab nickel alloys suav nrog kev tiv thaiv kom xeb, cua sov, thiab hnav.
Nickel yog cov paub zoo yog cov khoom tseem ceeb ua ke hauv cov hlau tsis muaj zog, ni-cu alloys, super alloys-resistant thiab kub alloys. Nickel Ferromagnetic nrog lub ntom ntom ntawm 8.9 g / cm3. Nws yog ducile thiab mallyable zoo li hlau. Nickel alloys tau paub zoo rau lawv lub zog kub siab thiab zoo ua rau xeb.
Ntawm Nickel alloys
Cov Nickel alloys tuaj yeem raug cais ua cov pab pawg hauv qab no raws li lawv cov tshuaj lom neeg muaj pes tsawg leeg:
(1) npib tsib xee
Ntshiab Nickel (99.56%)
Cov lag luam ntshiab npib tsib xee (wrought) 99.6-99.7%.
(2) npib tsib xee thiab tooj
Tsawg Nickel alloys (2-13% ni)
Cupronickel (10-30% ni)
Tsis muaj cov ntaub ntawv sib nqus (~ 60% ni)
High nickel alloys (tshaj 50% ni)
(3) npib tsib xee thiab hlau
Wring kom muaj alloys hlau (0. 5-9% ni)
Nrum alloy hlau ({0}}}. 5-0.9% ni)
Alloy cam khwb cia hlau (1-6, 14-36% ni)
(4) Cov hlau-npib tsib xee thiab chromium alloys
Stainless hlau (2-25% ni)
Marages cov hlau (18% ni)
(5) Nickel-chromium-molybdenum thiab hlau-npib tsib xee daus daus los daus.
