Kev ua tau zoo thiab kev siv ntau yam ntawm cov hmoov metallurgy raw cov ntaub ntawv feem ntau nyob ntawm lawv txoj kev npaj. Cov txheej txheem hmoov sib txawv txiav txim siab txog morphology, particle loj tis, purity, thiab cov qauv sab hauv ntawm cov hmoov, yog li cuam tshuam rau kev tsim thiab sintering tus cwj pwm. Mastering cov hauv paus ntsiab lus thiab cov yam ntxwv ntawm ntau yam kev npaj yog qhov yuav tsum tau ua ua ntej kom ua tiav cov khoom siv raw thiab kev ua kom zoo dua qub.
Kev npaj cov hmoov hlau yog feem ntau muab faib ua ob pawg: cov txheej txheem ntawm lub cev thiab cov txheej txheem tshuaj. Ntawm cov txheej txheem ntawm lub cev, atomization yog siv dav tshaj plaws, suav nrog roj atomization thiab dej atomization. Gas atomization siv lub siab - cua ntws ceev kom tawg cov hlau molten rau hauv cov tee dej thiab ua kom lawv khov sai, ua rau cov hmoov uas feem ntau yog kheej kheej nrog zoo flowability, haum rau siab -precision pressing. Dej atomization siv siab - lub dav hlau dej siab los cuam tshuam cov yaj, ua rau cov cua txias siab, ua cov hmoov uas feem ntau tsis sib xws, nrog rau qhov chaw ntxhib thiab muaj zog ntsuab lub cev sib txuas. Txoj kev plasma rotating electrode melts thiab atomizes spherical hmoov siv lub siab -rotating electrode, ua hmoov nrog zoo purity thiab sphericity, feem ntau siv nyob rau hauv siab -kev ua tau zoo alloys. Cov txheej txheem tshuaj muaj xws li kev txo qis, txoj kev electrolysis, thiab cov txheej txheem carbonyl. Txoj kev txo qis siv cov hlau oxides ua cov khoom siv raw, txo lawv nrog hydrogen lossis carbon kom tau cov hmoov. Cov txheej txheem no yog qhov paub tab, tus nqi qis, thiab tsim nyog rau cov khoom lag luam loj xws li hmoov hlau. Electrolysis txoj kev tau txais siab -cov hmoov purity los ntawm electrochemical deposition, nrog tswj morphology, thiab feem ntau yog siv rau conductive cov ntaub ntawv xws li tooj liab thiab npib tsib xee. Cov txheej txheem carbonyl siv cov thermal decomposition ntawm hlau carbonyl compounds los tsim ultrafine, siab -purity hmoov, haum rau tshwj xeeb functional applications.
Kev npaj ntawm cov hmoov uas tsis yog-nws yog xim hlau encompasses txoj kev xws li kev sib tsoo tshuab, tshuaj synthesis, thiab siab - qhov kub thiab txias. Ceramic thiab carbide hmoov feem ntau tau txais los ntawm siab - kub khoom - xeev cov tshuaj tiv thaiv los yog vapor - theem deposition, nrog particle loj thiab crystallinity tswj tau raws li cov tshuaj tiv thaiv. Graphite hmoov feem ntau tau los ntawm ntuj flake graphite los ntawm kev sib tsoo thiab kev faib tawm; lattice defects yuav tsum tau tswj kom tsis txhob muaj kev ua haujlwm degradation.
Kev npaj cov ntaub ntawv pab qhia txog qhov sib xws thiab kev ruaj ntseg ntawm cov formulation. Lubricants feem ntau tau los ntawm kev sib tov thiab tshuaj tsuag kom qhuav, thaum cov binders tuaj yeem ua tiav qhov xav tau viscoelasticity los ntawm polymerization lossis blending txheej txheem.
Feem ntau, txoj kev npaj rau hmoov metallurgy raw cov ntaub ntawv muaj ntau haiv neeg, txhua tus muaj nws tus kheej zoo thiab kev txwv. Los ntawm kev txiav txim siab xaiv thiab sib txuas cov txheej txheem ua haujlwm tom ntej, qhov sib npaug zoo tuaj yeem ua tiav ntawm morphology, purity, thiab kev ua tau zoo, muab cov khoom siv raw khoom lav rau siab - cov khoom zoo.
