Vanadium Nitrogen Alloy nrog cov yam ntxwv zoo

Vanadium-nitrogen alloy yog cov khoom sib xyaw ua los ntawm vanadium pentoxide, carbon hmoov, activator thiab lwm yam khoom siv raw. Nyob rau hauv qhov kub thiab txias, cov khoom siv raw no raug tshuaj lom neeg los tsim cov vanadium-nitrogen alloys. Vanadium-nitrogen alloy feem ntau yog siv rau hauv kev tsim cov hlau microalloyed, uas tuaj yeem txhim kho lub zog thiab tawv ntawm cov hlau thiab txuag steel noj. Vanadium nitride ntxiv rau cov hlau tuaj yeem txhim kho cov khoom siv dav dav ntawm cov hlau xws li lub zog, toughness, ductility thiab thermal fatigue resistance. Qhov sib ntxiv ntawm vanadium-nitrogen alloy kuj tuaj yeem ua rau cov hlau muaj qhov zoo weldability. Txhawm rau ua tiav tib lub zog, ntxiv vanadium nitride tuaj yeem txuag tau 30-40% ntawm vanadium ntxiv, yog li txo cov nqi.

Cov txheej txheem tseem ceeb ntawm cov khoom siv rau kev tsim cov vanadium-nitrogen alloy yog ib qho chaw nruam thawb phaj siab kub rauv, uas siv hluav taws xob cua sov cov ntsiab lus xws li silicon-molybdenum rods kom tau txais cov cua sov. Nyob rau hauv ib txwm muaj siab thiab nitrogen huab cua tiv thaiv, cov blanks ua los ntawm raw cov ntaub ntawv xws li vanadium pentoxide, carbon hmoov, thiab activator yog muab tso rau hauv lub kub-kub rauv thiab hnov ​​nyob rau ntawm ib tug kub ntawm 1500 ~ 1800 degree los tsim vanadium-nitrogen alloy.

Vanadium-nitrogen alloy tuaj yeem siv rau hauv cov qauv hlau, cov cuab yeej hlau, cov raj xa dej, cov hlau tuav thiab cov cam khwb cia hlau txhawm rau txhim kho cov khoom siv dav dav ntawm cov hlau xws li lub zog, toughness, ductility thiab thermal fatigue resistance. Hauv kev tsim cov hlau tsis muaj zog tsawg, vanadium-nitrogen alloy tuaj yeem ua tau zoo micro-alloying ntawm vanadium thiab nitrogen tib lub sijhawm, txhawb cov nag lossis daus ntawm carbon, vanadium, thiab nitrogen tebchaw hauv cov hlau, thiab ua si zoo dua. lub luag hauj lwm ntawm sedimentation strengthening thiab grain refinement. Cov tshiab qib peb qib steel tuav uas tsim los siv vanadium-nitrogen alloying tshuab tsis tsuas yog txhim khu kev ruaj ntseg thiab av qeeg tsis kam ntawm lub tsev vim nws muaj zog, tab sis kuj txuag 10% mus rau 15% ntawm cov hlau piv rau kev siv cov hlau thib ob. tuav.

Vanadium-nitrogen alloys yog cov ntaub ntawv zoo tshaj plaws rau kev lag luam aerospace vim lawv lub zog siab, hnav tsis kam thiab corrosion kuj, xws li kev tsim cov cav cav, cov khoom siv dav hlau, thiab lwm yam. Vanadium-nitrogen alloys tuaj yeem siv los tsim cov khoom siv tsheb loj. , xws li cav pistons, gears, bearings, thiab lwm yam, los txhim kho kev ua tau zoo thiab kev nyab xeeb ntawm tsheb. Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam steel, qhov kev thov rau cov hlau ua haujlwm siab tau nce ntxiv. Raws li ib qho tseem ceeb alloy additive, kev lag luam thov rau vanadium-nitrogen alloy tseem loj hlob. Kev tshawb fawb thiab kev tsim kho thiab kev tsim khoom siv tshuab ntawm vanadium-nitrogen alloy tau txhim kho tas li, thiab nws yuav tsum tau siv rau hauv ntau thaj chaw yav tom ntej, nrog rau kev lag luam dav dav.
