Kev piav qhia
Cr3C2-NiCr yog cov khoom siv zoo sib xyaw siv dav hauv kev lag luam uas xav tau kub thiab hnav tsis kam.Cov khoom siv yog tsim los ntawm chromium carbide (Cr3C2) thiab npib tsib xee-chromium (NiCr) alloy, ua rau nws yog ib qho kev daws teeb meem zoo tshaj plaws rau kev siv qhov kub-kub oxidation thiab hnav tsis kam.
KF-70, KF-69, thiab KF-71 qib ntawm Cr3C2-NiCr paub txog lawv cov kev ua tau zoo thiab ua haujlwm ntev nyob rau hauv qhov kub thiab txias.Qhov loj me ntawm txhua qib yog li ntawm 15-45 μm thiab 20-53 μm, thiab lawv tau agglomerated thiab sintered kom ntseeg tau tias muaj zog tshaj plaws.
KF-70 Cr3C2-25NiCr muaj kev tiv thaiv zoo heev rau oxidation thiab hnav ntawm 815 ℃.Nws yog qhov pom zoo rau cov ntawv thov nyob rau hauv qhov chaw kub kub uas yuav tsum tau ua haujlwm ntev, xws li turbine blades thiab gas turbine engines.
KF-69 Cr3C2-20NiCr yog lwm qib zoo uas muaj kev tiv thaiv zoo tshaj rau oxidation thiab hnav ntawm 815 ℃.Nws yog qhov zoo tagnrho rau kev siv ntau yam kev siv kub-kub, nrog rau kev ua tshuaj lom neeg thiab kev kho cua sov.
KF-71 Cr3C2-30NiCr yog cov qib ua tau zoo tshaj plaws uas muaj qhov tawv zoo dua li lwm qib hauv tsev neeg Cr3C2-NiCr.Nws yog qhov pom zoo rau cov ntawv thov uas qhov kev ua haujlwm ntev thiab qhov hnyav yog qhov tseem ceeb, xws li cov cuab yeej siv roj thiab roj, cov pwm kub kub, thiab cov cuab yeej tuag casting.
Hauv cov ntsiab lus, Cr3C2-NiCr tsev neeg ntawm cov khoom, suav nrog KF-70, KF-69, thiab KF-71, yog ib qho kev daws teeb meem zoo tshaj plaws rau cov ntawv thov uas yuav tsum muaj qhov kub thiab txias oxidation thiab hnav tsis kam.Cov khoom no muaj kev ua tau zoo dua thiab muaj zog nyob rau hauv qhov kub thiab txias, ua rau lawv zoo tagnrho rau kev siv hauv kev lag luam xws li aerospace, automotive, thiab lub zog.Nrog lawv cov kev ua tau zoo thiab kev ntseeg tau zoo, Cr3C2-NiCr cov khoom yog qhov kev xaiv zoo tshaj plaws rau txhua tus neeg uas tab tom nrhiav kev ua haujlwm zoo, siv tau ntev rau kev siv kub.
