Microstructure ntawm Stainless hlau hmoov

Microstructure ntawm Stainless hlau hmoov
Qhov loj ntawm cov hmoov hlau:
Feem ntau, txoj kab uas hla ntawm 3D luam ntawv hlau hmoov zoo dua. Qhov no yog vim hais tias yog hais tias lub cheeb ntawm cov hmoov yog me me, qhov zoo dua sintering nyhuv thaum lub sij hawm sintering txheej txheem, thiab lub zog tsav ntawm sintering kuj yuav nce. Ntxiv mus, qhov me me ntawm txoj kab uas hla, qhov sib txawv me me thaum lub sij hawm stacking, yog li xyuas kom meej qhov zoo thiab lub zog ntawm cov khoom. Txawm li cas los xij, txoj kab uas hla ntawm cov hmoov yuav tsum tsis txhob me npaum li qhov ua tau, xws li txoj kab uas hla ntawm cov hmoov me me dhau, nws yuav ua rau spheroidization thaum lub sij hawm sintering, ua rau cov hmoov tsis sib xws thiab cuam tshuam rau kev luam ntawv. Qhov tseeb.
Hlau hmoov purity:
Tsis tas li ntawd, cov ntsiab lus ntawm oxygen thiab nitrogen kuj yuav tsum tau tswj nruj me ntsis. Tam sim no, cov hmoov npaj tshuab siv rau hlau 3D luam ntawv feem ntau yog raws li txoj kev atomization. Cov hmoov muaj qhov tshwj xeeb ntawm thaj chaw loj thiab nws yooj yim rau oxidation. Hauv kev siv tshwj xeeb xws li aerospace, cov neeg siv khoom muaj cov kev cai nruj dua rau qhov ntsuas no, xws li cov hmoov hlau kub kub. Cov ntsiab lus oxygen yog 0.006 feem pua ​​-0.018 feem pua, titanium alloy hmoov muaj cov pa oxygen ntawm 0.007 feem pua ​​-0.013 feem pua ​​, thiab stainless hlau hmoov muaj cov pa oxygen ntawm 0.010 feem pua ​​-0.025 feem pua ​​.
Particle loj faib ntawm hlau hmoov:
Kev xaiv cov hmoov hlau hmoov me me rau 3D luam ntawv feem ntau yog ua los ntawm cov tshuab luam ntawv hlau uas muaj zog sib txawv. Cov tshuab luam ntawv uas siv lasers li lub zog muaj qhov ua kom pom tseeb zoo thiab muaj ntau dua rau cov hmoov zoo. Haum rau kev siv 15-53 μ M hmoov ua khoom siv. Txoj kev ua hmoov ntxiv yuav tsum tau nthuav tawm cov hmoov txheej los ntawm txheej; Cov hmoov sib kis tshuab siv los ntawm cov kab hluav taws xob muaj cov ntsiab lus tuab me ntsis, ua rau lawv tsim nyog rau melting coarse hmoov, feem ntau haum rau 53-105 μ Coarse hmoov ntawm m; Siv rau coaxial hmoov pub hom. Rau cov tshuab luam ntawv, qhov loj me me yog 105-150 μ Cov hmoov ntawm m tuaj yeem siv los ua khoom siv.
