Cov txheej txheem sintering hauv kev tsim thiab ua cov hmoov metallurgy qhov chaw yog ib qho ntawm cov txheej txheem yooj yim tshaj plaws ntawm cov hmoov metallurgy, uas ua lub luag haujlwm txiav txim siab hauv lub cev thiab cov khoom siv ntawm cov hmoov metallurgy qhov chaw.

Sintering yog kev kho cua kub kub, uas muaj kev paub txog ntawm sintering rauv, sintering cua, xaiv thiab tswj ntawm sintering tej yam kev mob, thiab lwm yam. Yog li ntawd, sintering yog ib tug heev nyuaj txheej txheem. Nyob rau tib lub sijhawm, sintering yog txheej txheem tshwj xeeb nrog kev siv lub zog loj, cov cuab yeej siv siab, thiab kev ntsuas tsis txaus ntawm cov khoom zoo, yog li nws yog ib qho tseem ceeb tshaj plaws uas cuam tshuam rau qhov zoo thiab tus nqi ntawm cov hmoov metallurgy qhov chaw. Cov txheej txheem sintering yog qhov tseem ceeb heev thiab yuav tsum tau tswj nruj me ntsis kom ntseeg tau qhov zoo ntawm sintered qhov chaw. Yog li ntawd, cov neeg ua haujlwm yuav tsum tau ua cov kev cob qhia tshwj xeeb, nkag siab thiab paub txog cov hauv paus ntsiab lus ntawm sintering, txheej txheem sintering (xws li cov ntaub ntawv, kub thiab sijhawm, sintering cua, ib puag ncig, thiab lwm yam), lub luag haujlwm ntawm sintering cua, thiab yam cuam tshuam rau qhov zoo ntawm cov khoom sintered, thiab lwm yam. Yuav kom paub qhov kev ua haujlwm sintering kom paub meej thiab txhim kho lub peev xwm los soj ntsuam cov teeb meem.

Yuav ua li cas yog lub compact ntawm hmoov metallurgy qhov chaw sintered?

Sintering yog kev kho cua sov ntawm cov hmoov los yog compacts ntawm qhov kub thiab txias hauv qab lub melting point ntawm lub ntsiab Cheebtsam. Lub hom phiaj yog los tsim ib daim ntawv cog lus metallurgical ntawm cov hmoov nplej, uas yog, cov khoom sib txuas ntawm cov hmoov nplej tau hloov mus rau hauv cov qoob loo ciam teb ntawm cov atoms.

Ntsiav tshuaj PM sintered qhov chaw Lub hom phiaj ntawm compact sintering yog hais tias txawm lub compact tau los ntawm nias muaj cov duab thiab loj ntawm cov neeg kho tshuab qhov chaw, nws lub zog yog tsawg heev thiab tsis tau raws li qhov yuav tsum tau ntawm kev siv. Ua ntej sintering, lub compact tsuas yog ib tug sib tov ntawm hmoov hais nyob rau hauv kev sib cuag nrog lub interface, tsis yog ib tug tiag tiag atomically bonded khoom. Yog li ntawd, sintering yog tsim nyog los ua kom lub compact mus rau hauv lub siab ntawm metallurgy, thiab endow hmoov metallurgy qhov chaw uas yuav tsum tau txhua yam thiab lub cev zog. Tom qab cov hlau hmoov compact yog sintered, lub zog thiab elongation tau zoo heev. Yog tias qhov kub thiab txias yog sintered ntawm 1200 ° C, lub zog tensile tuaj yeem nce ntawm xoom mus rau 200MPa, thiab elongation tuaj yeem nce ntawm xoom mus rau 8 feem pua.

Yuav tsum tau rau compact sintering ntawm hmoov metallurgy machinery qhov chaw

1. Qhov yuav tsum tau muaj rau qhov loj thiab cov duab.

Qhov loj thiab cov duab raug ntawm sintered qhov chaw, nrog rau qhov chaw roughness, yuav tsum ua kom tau raws li cov qauv tsim. Sintering ua rau shrinkage los yog expansion ntawm lub cev sintered, thiab deformation ntawm lub sintered lub cev vim tsis sib xws ceev faib ntawm lub compact thiab tsis sib xws rauv kub, yog li ntawd qhov luaj li cas thiab cov duab ntawm sintered khoom yuav hloov los ntawm sintering. Qhov no yuav tsum muaj kev tswj hwm nruj ntawm sintering tej yam kev mob txhawm rau kom ntseeg tau tias qhov loj thiab cov duab raug cov cai ntawm cov khoom sintered.

2. Cov kev xav tau ceev.

Nyob rau hauv sintering, txij li thaum sintering ntawm hmoov hais tshwm sim, thiab shrinkage los yog expansion ntawm cov khoom sintered tshwm sim, qhov ceev, porosity, thiab voids ntawm sintered khoom hloov nrog rau cov duab. Cov txheeb ze ntom ntom thiab porosity characterizes qhov ntom ntawm hmoov metallurgy qhov chaw. Raws li tus kheej-lubricating hmoov metallurgy roj-impregnated bearing, kuj muaj qhov yuav tsum tau rau kev sib txuas qhov khoob.

3. Lub koom haum xav tau.

Hmoov metallurgy qhov chaw yog tib yam li lwm cov ntaub ntawv, thiab lawv cov khoom siv sab hauv yog nyob ntawm tus qauv. Cov yam ntxwv ntawm cov qauv ntawm cov hmoov nplej yog cov nplej loj, theem qauv, theem faib, faib cov khoom siv hlau, porosity, pore loj, thiab porosity. puab. Kev tsim thiab kev hloov ntawm microstructure ntawm hmoov metallurgy qhov chaw feem ntau tshwm sim thaum lub sij hawm sintering.

4. Kev xav tau rau cov khoom siv kho tshuab thiab lub cev muaj zog.

Qhov kawg sintered qhov chaw yuav tsum ua kom tiav cov khoom siv kho tshuab thiab lub cev muaj zog. Mechanical zog muaj xws li lub zog, hardness, elongation thiab cuam tshuam toughness, thiab lwm yam.; Lub cev muaj zog muaj xws li qhov ntom ntom, hluav taws xob conductivity, thermal conductivity, thiab cov khoom sib nqus.

Lub sintering ntawm hmoov metallurgy qhov chaw yog muab faib ua cov khoom-theem sintering thiab kua-theem sintering. Khoom-theem sintering yog tsuas yog sintering ntawm metallurgical bonding ntawm hmoov metallurgy hais, thiab kua-theem sintering yog sintering ntawm tej molecular hais nyob rau hauv hmoov metallurgy ntawm ib tug kub siab tshaj lub melting point los tsim ib lub xeev cov kua. Cov txheej txheem sintering ntawm hmoov metallurgy compact qhov chaw tuaj yeem muab faib ua ntej sintering roj tshem tawm-siab kub sintering-txias. Ntsiav tshuaj PM sintered qhov chaw txais mesh siv rauv rauv nruam sintering txheej txheem thiab lub tshuab nqus tsev batch sintering, uas muaj peev xwm tsim nyog thiab txawj tswj cov txheej txheem sintering ntawm ntau yam hlau-raws li, tooj liab-raws li, thiab stainless hlau mechanical qhov chaw. Zoo meej sintering txheej txheem tswj plays ib qho kev sib txuas ntawm yav dhau los thiab yav tom ntej rau qhov zoo ntawm hmoov metallurgy qhov chaw.
