Kev siv cov khoom siv Niobium
Kev tiv thaiv thermal thiab cov khoom siv hauv kev lag luam aviation thiab aerospace, cov raj hluav taws xob thiab lwm yam khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob kub thiab cov cemented carbides, thiab lwm yam.
Niobium Khoom Taw Qhia
Peb cov nplooj ntawv niobium yog txias dov thiab lub tshuab nqus tsev vacuum annealed nrog proprietary txo tus nqi kom ntseeg tau tias zoo tagnrho metallurgy.Txhua daim ntawv tau soj ntsuam nruj me ntsis rau qhov ntev, qhov chaw tiav, thiab flatness.
Niobium daim ntawv yog lub teeb tshaj plaws refractory hlau (qhov ceev 8.57 g / cc) thiab muaj kub melting kub (2,468ºC).Cov cuab yeej no tso cai rau nws cov alloys los muab cov qauv kev daws teeb meem ntawm qhov kub thiab txias: siab dua 600ºC hauv cov nickel raws li alloys thiab siab li 1,300ºC hauv niobium raws li alloys.
Niobium daim ntawv muaj lub cev thiab tshuaj lom neeg zoo ib yam li cov ntsiab lus tantalum.Nws tiv taus corrosion raws li nws daim ntawv dielectric oxide zaj duab xis.Cov hlau pib oxidize sai hauv huab cua ntawm 200 ºC.
Hauv qab -264ºC, niobium nthuav tawm cov khoom siv hluav taws xob.Nws ua haujlwm siab ntawm hluav taws xob tam sim-dawb, tsim kev sib nqus ntawm cov ntawv thov hauv cov chaw xws li kev tshawb fawb kho mob, cov ntaub ntawv tshawb fawb thiab kev thauj mus los.
