Lub Luag Haujlwm ntawm Cov Khoom Sib Xyaws: Hlau, Nickel, Chromium, thiab Tshaj Plaws
Cov khoom ntxiv rau hauv cov hlau no ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov khoom siv thiab kev tiv thaiv xeb. Cov ntsiab lus Chromium txij li 19% txog 23% ua rau muaj txheej oxide tiv thaiv tas mus li, ua rau muaj kev tiv thaiv zoo tiv thaiv cov neeg sawv cev corrosive thiab txhim kho lub neej ntev ntawm cov hlau tsis xeb thiab superalloys. Nickel ua rau cov qauv siv lead ua ruaj khov thiab ua rau muaj kev tiv thaiv kub, tshwj xeeb tshaj yog hauv cov hlau-nickel-chromium alloy systems. Kev ntxiv molybdenum, ntawm qib txog li 9%, ua rau muaj kev tiv thaiv rau kev xeb pitting thiab crevice uas pom muaj nyob rau hauv dej hiav txwv thiab cov chaw muaj tshuaj lom neeg hnyav. Hlau pab txhawb kev ruaj khov ntawm kev ua kom cov kua muaj zog thiab muab kev txuag nyiaj hauv ntau qib.
Qhov Tseem Ceeb ntawm Kev Txheeb Xyuas Cov Khoom Muaj Peev Xwm Tseeb
Kev Ua Tau Zoo, Kev Ua Raws Cai, thiab Kev Siv Tau Ntev
Cov ntaub ntawv qhia txog cov khoom sib xyaw ua ke kom ntseeg tau tias cov hlau nickel ua tau raws li cov qauv kev siv tshuab thiab kev nyab xeeb hauv kev tsim hluav taws xob thiab kev tsim hluav taws xob. Cov hlau, nickel, thiab chromium uas tswj tau zoo (piv txwv li, 60–75% Ni, 19–23% Cr) cuam tshuam ncaj qha rau lub zog tensile thiab kev tiv thaiv creep ntawm 700–1100 ° C. Kev tshuaj xyuas tsis raug tuaj yeem ua rau muaj kev tawg tsis tau xav txog, poob qhov kub siab, lossis kev puas tsuaj loj heev hauv cov khoom siv hnyav. Kev lees paub zoo thiab kev taug qab tau vam khom kev txheeb xyuas cov khoom sib xyaw kom raug rau kev ua raws li txoj cai thiab kev lees paub lav.
Cov Chromium Cov Ntsiab Lus thiab Kev Tiv Thaiv Corrosion
Chromium ntawm 19–23% tsim ib zaj duab xis Cr₂O₃ oxide tas mus li, tseem ceeb rau kev tiv taus cov kua qaub, caustics, thiab oxidation kub siab. Kev tiv taus xeb ntawm cov hlau tsis xeb xav tau qhov tsawg kawg nkaus chromium feem pua: qis dua 19% ua rau muaj kev sib tsoo thiab kev tawm tsam intergranular ntau ntxiv. Hauv cov hlau nickel-chromium-iron siv hauv cov nroj tsuag tshuaj, kev poob ntawm 2% chromium txo lub neej ua haujlwm los ntawm 40%, ua rau muaj kev saib xyuas ntau ntxiv thiab kev tsis ua haujlwm tsis tau teem sijhawm.
Cov Kev Cov nyom tseem ceeb hauv kev tshuaj xyuas cov khoom siv rau cov hlau nickel
Hlau, nickel, thiab chromium muaj cov fluorescence peaks sib tshooj, ua rau XRF lossis spectroscopic quantification nyuaj. Cov matrices ntau yam nrog cov molybdenum me me lossis niobium xav tau kev calibration ruaj khov thiab kev raug. Kev ua yuam kev los ntawm cov teebmeem matrix lossis calibration drift ua rau kev faib cov hlau tsis raug, kev pheej hmoo ntawm kev ncaj ncees, lossis kev ua txhaum cai ntawm cov ntawv cog lus, nrog rau kev thov warranty thiab kev lav phib xaub.
