Cov lus piav qhia luv luv ntawm Niobium phiaj npaj
Molybdenum (10%) Niobium alloy alloy sputtering lub hom phiaj tuav daim ntawv thov cov zeem muag nyob rau hauv nyias {} Win} Zaj duab xis Hnub ci thiab cov lus qhia. Txawm li cas los xij, vim muaj cov pa oxygen ua los ntawm sintering, sintered molybdenum- niobgen cov ntsiab lus muaj cov ntsiab lus oxygen thiab ntom ntom. Txoj kev tshawb no npaj Niobium hmoov coated nrog niobium carbon (nbc) ntawm cov tshuaj vapor tshuaj lom neeg hauv ib lub ch4 cua.
NBC txheej tsis tsuas yog txwv tsis pub ua pa oxygen tab sis kuj rov ua kom zoo nrog nws kom ua kom tiav oxygen ntawm qhov ntsuas kub. Qhov cuam tshuam ntawm txoj kev npaj npaj, kev tshuaj tiv thaiv nruab nrab, thiab cov txheej txheem ntawm kev coj ua tau raug txiav txim siab: thiab lub sijhawm ntawm 60 feeb, thiab siab ntawm 0.04 MPA.
Lub ntsej muag saum npoo, cov khoom siv tshuaj lom neeg, faib tshuaj, thiab kev coj ua hluav taws xob tau pom tias siv hluav taws xob, x}} pa taws duab, thiab atomic quab yuam microscopy. Cov pa oxygen thiab cov khoom siv carbon tau txiav txim siab siv onh thiab cs analalyzers. Deg |-} hloov kho cov hmoov molybenter ntawm 1990 ppm, thiab ib qho kev txheeb ze ntawm 93%. Qhov zoo tshaj ntawm kev ingot no tau ntau dua zoo dua li kev ua haujlwm npaj siv unmodified niobium hmoov.
