Khawv koob ntawm Fusing Hlau Tsis Melting

 

Taw qhia

Sintering yog cov txheej txheem hloov pauv uas ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv hlau ua haujlwm siab,

suav nrogntxeem tau hlau lim, sintered stainless hlau npog, sintered suction lim,av noo vaj tse, ISO KF lim, Sparger thiab lwm yam.

 

Cov txheej txheem no suav nrog kev cog cov hmoov hlau thiab cua sov hauv qab lawv cov ntsiab lus melting,cia cov khoom sib txuas

thiab tsim ib qho khoom siv.Txoj kev no yog qhov tseem ceeb rau kev tsim cov khoom siv nrog cov lus qhia meej thiab txhim kho

mechanical zog.

 

Ib lo lus nug tseem ceeb tshwm sim:

Yuav ua li cas hlau hais fuse rau hauv ib qho khoom tsis muaj melting?

Cov lus teb yog nyob rau hauv cov hauv paus ntsiab lus ntawm solid-state sintering, qhov twg diffusion thiab particle rearrangement tshwm sim

ntawm qhov kub thiab txias, ua kom muaj zog ntawm cov khoom sib txuas sib txuas.

Yog li cia peb qhia cov ntsiab lus ntxiv thiab tham txhua yam txog Solid-State Sintering hauv qab no.

 

Solid-State Sintering yog dab tsi?

Solid-state sintering yog cov txheej txheem tsim khoom siv los tsim cov khoom siv los ntawm cov hmoov hlau los ntawm kev siv cua sov thiab siab.

tsis pub cov ntaub ntawv yaj.

Txoj kev no txawv nws tus kheej los ntawm lwm yam kev tsim khoom, tshwj xeeb yog cov uas koom nrog cov hlau liquefied, xws li

casting lossis vuam, qhov twg cov ntaub ntawv hloov mus rau hauv lub xeev ua kua ua ntej solidification.

 

Nyob rau hauv solid-state sintering, hlau hais yog compacted ua ke thiab raug rau kub kub, feem ntau hauv qab lub melting.

point ntawm lub hauv paus hlau.

Qhov cua sov no ua kom yooj yim rau atomic diffusion - kev txav ntawm atoms hla ciam teb ntawm cov khoom uas nyob ib sab

- tso cai rau lawvdaim ntawv cog lus thiab tsim ib cohesive khoom loj.

Raws li qhov kub thiab txias, cov khoom siv rov ua dua thiab loj hlob ua ke, txhim kho lub zog thiab kev ncaj ncees ntawm cov khoom kawg.

Tus yuam sijtxoj caiTom qab solid-state sintering yog tias fusion ntawm hlau hais tshwm sim ntawm qhov kub thiab txias yam tsis muaj

xav kom lawv ua kua.

 

 

Qhov kev qhia tshwj xeeb no ua rau cov tuam txhab tsim khoom kom ua tiav cov khoom xav tau hauv cov khoom kawg thaum tswj qhov seem

raug thiab tiv thaiv cov teeb meem xws li shrinkage lossis distortion uas tuaj yeem tshwm sim los ntawm melting. Yog li ntawd, solid-state sintering yog dav

siv nyob rau hauv daim ntaub ntawv uas high-performance thiab precision yog qhov tseem ceeb, xws li nyob rau hauv zus tau tej cov porous hlau lim.

 

Lub luag hauj lwm ntawm qhov kub thiab txias hauv Solid-State Sintering

Solid-state sintering yog cov txheej txheem uas ua kom sov cov khoom hlau mus rau qhov kub hauv qab lawv cov ntsiab lus melting, ua rau lawv "mos"

thiab nce lawv atomic mobility. Qhov kev txhim kho atomic kev txav mus los no yog qhov tseem ceeb rau cov txheej txheem sintering, vim nws tso cai rau cov atoms

nyob rau hauv cov hlau hais kom txav tau yooj yim dua.

Thaum lub sij hawm solid-state sintering, lub siab yog siv rau cov hlau hais, coj lawv los ze zog ua ke thiab pab txhawb atomic diffusion.

Atomic diffusion yog qhov txav ntawm atoms hauv cov khoom siv, tso cai rau cov atoms ntawm ib qho hlau mus rau hauv qhov chaw.

nruab nrab ntawm lwm yam. Qhov ntim ntawm qhov khoob no los ntawm atomic diffusion ua rau muaj cov khoom denser thiab ntau cohesive.

Nws yog ib qho tseem ceeb uas yuav tsum tau hais txog tias thoob plaws hauv cov txheej txheem sintering khoom, cov khoom tseem nyob ruaj khov.

Cov khoom hlau tsis yaj;Hloov chaw, lawv dhau los ua "mos" txaus los ua kom muaj atomic diffusion, ua rau tsim

ntawm ib tug denser, ntau ruaj khov qauv.

 

Atomic Diffusion: Qhov zais cia tom qab Particle Fusion

Atomic diffusion yog ib lub tswv yim tseem ceeb hauv kev ua haujlwm hauv lub xeev sintering uas piav qhia txog kev txav ntawm atoms ntawm ib qho mus rau lwm qhov, tshwj xeeb tshaj yog nyob rau thaj tsam uas lawv sib cuag. Cov txheej txheem no tseem ceeb heev rau kev sib xyaw ntawm cov hlau tsis muaj melting, tso cai rau lawv tsim kom muaj zog, cohesive bonds.

Thaum cov khoom siv hlau raug cua sov, lawv cov atoms tau txais lub zog, uas ua rau lawv txoj kev txav mus los. Ntawm cov ntsiab lus sib txuas ntawm ob qhov, qee cov atoms tuaj yeem txav los ntawm ib qho mus rau qhov khoob ntawm lwm qhov. Qhov kev txav ntawm atomic no tshwm sim feem ntau ntawm qhov chaw thiab cov npoo uas cov khoom sib chwv, tsim kom muaj kev sib xyaw ntawm cov ntaub ntawv. Raws li atoms los ntawm ib tug particle diffuse mus rau cov nyob sib ze particle, lawv sau nyob rau hauv voids, zoo fusing ob particles ua ke.

Qhov tshwm sim ntawm no atomic diffusion yog tsim ntawm cov khoom muaj zog ntawm cov khoom, txhim kho cov khoom siv ntawm cov khoom. Txij li cov txheej txheem no tshwm sim ntawm qhov kub thiab txias hauv qab lub melting point, qhov kev ncaj ncees ntawm cov qauv hlau yog tswj, tiv thaiv cov teeb meem uas tuaj yeem tshwm sim los ntawm melting, xws li distortion lossis tsis xav tau theem hloov.

 

Puas Muaj Kev Ciam Teb Ntawm Cov Hlau Particles Tiag Tiag?

Ib lo lus nug ntau txog cov txheej txheem sintering yog seb thaj tsam ntawm ib tus neeg hlau puas ploj mus. Cov lus teb yog nuanced: thaum cov khoom ua ib feem fuse thaum lub sij hawm sintering, qee qhov ciam teb tuaj yeem pom nyob ntawm qhov degree ntawm sintering thiab cov kev cai tshwj xeeb ntawm daim ntawv thov.

Thaum lub sij hawm sintering txheej txheem, raws li atomic diffusion tshwm sim, hais tias txav los ze zog ua ke thiab sib txuas ntawm lawv cov ntsiab lus sib cuag. Qhov kev sib txuas no ua rau txo qis ntawm cov ciam teb pom, tsim kom muaj kev sib koom ua ke ntau dua. Txawm li cas los xij, kev ploj ntawm tag nrho cov ciam teb tsis zoo li, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov xws li cov ntxaij lim dej ntxeem tau, qhov uas tswj tau qee qhov ntawm cov porosity yog qhov tseem ceeb rau kev ua haujlwm.

Hauv cov ntxaij lim dej ntxeem tau hlau, piv txwv li, qee theem ntawm qhov ciam teb ciam teb yog qhov zoo. Cov ciam teb no pab txhais cov qauv ntxeem tau, tso cai rau cov yam ntxwv txaus nyiam thaum tseem muab lub zog txaus. Nyob ntawm cov xwm txheej sintering - xws li qhov kub thiab txias, lub sijhawm, thiab kev siv siab - qee thaj tsam yuav nyob sib txawv, ua kom cov khoom khaws nws cov khoom ua haujlwm.

Zuag qhia tag nrho, thaum sintering txhawb kev sib raug zoo ntawm cov khoom thiab txo cov visibility ntawm ciam teb, qhov twg lawv ploj mus txawv raws li cov ntawv thov tshwj xeeb thiab cov yam ntxwv xav tau ntawm cov khoom kawg. Qhov kev sib npaug ntawm qhov sib txuas ntawm cov khoom sib txuas thiab kev tswj xyuas cov yam ntxwv tseem ceeb yog qhov tseem ceeb rau kev ua kom tau zoo hauv ntau yam kev siv.
