Qhov sib txawv tseem ceeb ntawm sintering thiab annealing yog sintering yog cov txheej txheem ntawm kev siv cov cua sov kom tshem tawm cov kev ntxhov siab sab hauv los ntawm qee cov ntaub ntawv, whereas annealing yog cov txheej txheem ntawm kev siv cua sov rau agglomerate hlau hais.
Sintering thiab annealing yog cov txheej txheem tseem ceeb uas muaj kev kho cua sov. Cov txheej txheem no suav nrog cov kauj ruam ua haujlwm sib txawv thiab kev ua haujlwm sib txawv ib yam nkaus.
Sintering yog dab tsi?
Sintering yog cov txheej txheem ntawm kev sib txuas ua ke me me ntawm cov hlau los ntawm kev siv cov cua sov hauv qab lub melting point ntawm cov hlau. Nws suav nrog kev siv cua sov kom tshem tawm cov kev ntxhov siab sab hauv los ntawm qee yam khoom siv. Cov txheej txheem no yog qhov tseem ceeb hauv kev tsim cov hlau. Kev siv cov txheej txheem sintering suav nrog kev tsim cov duab nyuaj, tsim cov alloys thiab muaj peev xwm ua haujlwm yooj yim nrog cov hlau uas muaj cov ntsiab lus melting siab.
Daim duab 01: Iron Powder
Hauv kev tsim khoom, peb yuav tsum siv lub txaj ntawm cov hmoov hlau los ntawm cov hlau ore. Cov hlau no yuav tsum tau tov nrog coke ua ntej siv nws. Tom qab ntawd lub txaj ntawm hlau yog ignited siv lub roj burner. Tom qab ntawd qhov kub hnyiab tau dhau los ntawm kev taug kev grate. Ntawm no peb yuav tsum kos cua los ntawm lub grate thiaj li yuav pib ib qho combustion cov tshuaj tiv thaiv. Tom qab ntawd muaj cua sov heev, uas ua rau cov khoom me me ntawm cov hlau tsim cov pob. Cov lumps no tsim nyog yuav tsum tau hlawv rau hauv lub qhov cub tawg kom thiaj li tsim tau cov hlau. Tsis tas li ntawd, cov txheej txheem sintering yog qhov tseem ceeb hauv kev tsim cov ceramic thiab iav thiab.
Yuav ua li cas?
Annealing yog txheej txheem kev kho cua sov uas peb yuav tsum tau ua kom sov cov hlau mus rau qhov kub tshaj plaws, tuav rau qee lub sijhawm, thiab tom qab ntawd txias nws los txhim kho ductility. Annealing yog tus txheej txheem ntawm softening ib cov khoom kom tau cov tshuaj thiab lub cev yam ntxwv. Qee yam ntawm cov khoom tsim nyog muaj xws li machinability, weldability, seem stability, thiab lwm yam.
Daim duab 02: Kev ntsuas kub ntawm qhov ntsuas kub
Cov txheej txheem annealing suav nrog cov cua sov ntawm cov hlau mus rau lossis ze qhov ntsuas kub tseem ceeb (qhov ntsuas kub tseem ceeb yog qhov kub ntawm qhov kub ntawm cov crystalline theem ntawm cov hlau hloov). Cua sov rau qhov kub siab ua rau nws tsim nyog rau fabricate. Tom qab cua sov, peb yuav tsum txias cov hlau mus rau chav tsev kub uas siv lub qhov cub.
Qhov txias qeeb ntawm cov hlau ua kom zoo dua microstructure. Qhov no tej zaum yuav ib nrab los yog tag nrho cais cov neeg. Txoj kev kho annealing yog siv rau cov hlau ntshiab thiab alloys thiab. Raws li cov txheej txheem no, muaj ob hom ferrous hlau raws li hauv qab no:
- Tag nrho cov annealed ferrous alloys (siv cov txheej txheem txias qeeb heev)
- txheej txheem annealed ferrous alloys (txias tus nqi yuav sai dua)
Lwm cov hlau xws li tooj dag, nyiaj, thiab tooj liab tuaj yeem ua tiav tag nrho, tab sis lawv yuav tsum tau txias sai sai siv txoj kev quenching hauv dej.
Qhov txawv ntawm Sintering thiab Annealing yog dab tsi?
Sintering thiab annealing yog cov txheej txheem tseem ceeb uas muaj kev kho cua sov. Qhov sib txawv tseem ceeb ntawm sintering thiab annealing yog tias sintering yog daim ntawv thov cua sov kom tshem tawm cov kev ntxhov siab sab hauv los ntawm qee cov ntaub ntawv, whereas annealing yog daim ntawv thov ntawm tshav kub rau agglomerate hlau hais.
Sintering yog cov txheej txheem ntawm kev sib txuas ua ke me me ntawm cov hlau los ntawm kev siv cov cua sov hauv qab lub melting point ntawm cov hlau. Annealing yog txheej txheem kev kho cua sov uas peb yuav tsum tau ua kom sov cov hlau mus rau qhov kub tshaj plaws, tuav rau qee lub sijhawm thiab tom qab ntawd txias kom nws thiaj li txhim kho ductility.
Hauv qab no yog ib daim ntawv qhia ntawm qhov sib txawv ntawm sintering thiab annealing.
Summary – Sintering vs Annealing
Sintering thiab annealing yog cov txheej txheem tseem ceeb uas muaj kev kho cua sov. Qhov sib txawv tseem ceeb ntawm sintering thiab annealing yog tias sintering yog daim ntawv thov cua sov kom tshem tawm cov kev ntxhov siab sab hauv los ntawm qee cov ntaub ntawv, whereas annealing yog daim ntawv thov cua sov rau agglomerate hlau hais.
