Product Description

Cov txheej txheem ntau lawm ntawm spline hmoov metallurgy sintered qhov chaw

1. Kev npaj cov khoom nyoos hmoov. Cov txheej txheem milling uas twb muaj lawm tuaj yeem muab faib ua ob pawg: cov txheej txheem siv tshuab thiab cov txheej txheem ntawm lub cev thiab tshuaj. Txoj kev siv tshuab tuaj yeem muab faib ua: mechanical crushing thiab atomization method; Txoj kev siv lub cev thiab tshuaj lom neeg tau muab faib ua: electrochemical corrosion method, txo txoj kev, chemical method, reduction-chemical method, vapor deposition method, kua deposition method thiab electrolytic method. Ntawm lawv, txoj kev siv dav tshaj plaws yog txoj kev txo qis, atomization txoj kev thiab txoj kev electrolysis.

2. Cov Spline PM Parts yog tsim rau hauv ib qho kev sib cog lus ntawm cov duab uas xav tau. Lub hom phiaj ntawm kev sib sau yog ua kom lub compact ntawm ib tug tej yam zoo thiab loj, thiab ua kom nws muaj ib tug tej yam ceev thiab lub zog. Txoj kev molding yog yeej muab faib ua siab molding thiab non-pressure molding. Compression molding yog feem ntau siv hauv compression molding. Tsis tas li ntawd, 3D tshuab luam ntawv kuj tseem siv tau los ua embryo blocks.

3. Sintering ntawm compacts. Sintering yog txheej txheem tseem ceeb hauv cov txheej txheem hmoov metallurgy. Lub compact tsim yog sintered kom tau qhov kawg yuav tsum tau lub cev thiab mechanical zog. Sintering yog muab faib ua chav tsev sintering thiab multi-system sintering. Rau cov khoom siv-theem sintering ntawm chav tsev thiab cov khoom siv ntau yam, qhov kub ntawm sintering yog qis dua qhov melting point ntawm cov hlau thiab alloy siv; Rau cov kua-theem sintering ntawm cov khoom siv ntau yam, qhov sintering kub feem ntau qis dua qhov melting point ntawm refractory tivthaiv thiab siab tshaj qhov melting point ntawm fusible tivthaiv. melting point. Ntxiv rau qhov zoo tib yam sintering, kuj tseem muaj cov txheej txheem sintering tshwj xeeb xws li xoob ntim sintering, immersion immersion method, thiab kub nias txoj kev.

4. Kev ua haujlwm tom qab ntawm cov khoom. Kev kho mob tom qab sintering tuaj yeem ua tau ntau yam raws li cov khoom sib txawv. Xws li kev ua tiav, roj immersion, machining, kev kho cua sov thiab electroplating. Tsis tas li ntawd, nyob rau xyoo tas los no, qee cov thev naus laus zis tshiab xws li dov thiab forging kuj tau siv rau kev ua cov hmoov hlau metallurgy tom qab sintering, thiab ua tiav cov txiaj ntsig zoo.

Powder Property (cov khoom ntawm hmoov)

Lub sij hawm dav dav rau tag nrho cov khoom ntawm hmoov. Nws suav nrog: cov khoom geometric ntawm cov hmoov (particle loj, qhov chaw tshwj xeeb, qhov pore loj thiab cov duab, thiab lwm yam); cov khoom siv tshuaj ntawm cov hmoov (tshuaj muaj pes tsawg leeg, purity, oxygen cov ntsiab lus thiab acid insolubles, thiab lwm yam); cov khoom siv ntawm cov hmoov (xws li ntom ntom, fluidity, thiab lwm yam), formability, compressibility, stacking lub kaum sab xis thiab shear lub kaum sab xis, thiab lwm yam. cov khoom ntawm lub cev thiab cov khoom saum npoo ntawm cov hmoov (qhov tseeb ntom ntom, gloss, yoj nqus, kev ua haujlwm saum npoo, ze li feem pua ​​​​26mdash; ta( feem pua ​​26ccedil;) muaj peev xwm thiab cov khoom sib nqus, thiab lwm yam). Cov khoom siv hmoov feem ntau txiav txim siab qhov ua tau zoo ntawm cov khoom siv hmoov metallurgy mus rau qhov loj.

Qhov tseem ceeb tshaj plaws ntawm cov khoom geometric yog qhov loj me thiab cov duab ntawm cov hmoov.

(1) Granularity. Nws cuam tshuam rau kev ua thiab shaping ntawm cov hmoov, lub shrinkage thaum lub sij hawm sintering thiab cov khoom kawg ntawm cov khoom. Kev ua tau zoo ntawm qee cov hmoov hlau metallurgy yog yuav luag ncaj qha ntsig txog qhov loj me me. Piv txwv li, qhov pom tseeb ntawm cov khoom siv lim tuaj yeem ua rau pom tau los ntawm kev faib qhov nruab nrab ntawm qhov loj me ntawm cov hmoov qub los ntawm 10; Txhawm rau kom tau txais cov cemented carbide nrog finer grain loj, nws tsuas yog siv tau finer grained WC raw cov ntaub ntawv. Cov hmoov siv nyob rau hauv kev xyaum ntau lawm muaj ib tug particle loj li ntawm ob peb puas nanometers mus rau ob peb puas microns. Qhov me me ntawm qhov me me, qhov ua haujlwm ntau dua, thiab qhov yooj yim ntawm qhov chaw yog oxidize thiab nqus dej. Thaum nws me me li ob peb puas nanometers, nws tsis yooj yim rau khaws thiab thauj cov hmoov, thiab thaum nws me me rau qee qhov, cov nyhuv quantum pib ua haujlwm, thiab nws lub cev lub cev yuav hloov pauv, xws li ferromagnetic. hmoov yuav dhau los ua superparamagnetic Powder, lub melting point kuj txo nrog cov particle loj txo.

Cov khoom yog dendritic; cov hmoov hlau hmoov tau los ntawm txoj kev txo qis yog nyob rau hauv cov duab ntawm daim txhuam cev flakes; cov uas tau los ntawm cov roj atomization txoj kev yog cov hmoov kheej kheej kheej kheej. Tsis tas li ntawd, qee cov hmoov yog qe-puab, disc-puab, koob-puab, dos-puab, thiab lwm yam. Cov duab ntawm cov hmoov hmoov yuav cuam tshuam cov fluidity thiab bulk ntom ntawm cov hmoov. Vim lub tshuab meshing ntawm cov khoom, lub zog compact ntawm cov hmoov tsis sib xws kuj yog siab, tshwj xeeb tshaj yog cov hmoov dendritic muaj lub siab tshaj plaws compact zog. Tab sis rau cov ntaub ntawv ntxeem tau, spherical hmoov yog qhov zoo tshaj plaws.

Mechanical zog Cov khoom siv ntawm cov hmoov yog cov txheej txheem ntawm cov hmoov, uas yog cov txheej txheem tseem ceeb hauv cov hmoov metallurgy txheej txheem. Qhov ntom ntom ntawm cov hmoov yog lub hauv paus rau qhov hnyav los ntawm txoj kev ntim ntim thaum nias; lub fluidity ntawm cov hmoov txiav txim siab filling ceev ntawm cov hmoov mus rau qhov tuag thiab lub peev xwm ntau lawm ntawm cov xovxwm; lub compressibility ntawm cov hmoov txiav txim siab qhov nyuaj ntawm cov txheej txheem nias thiab qib siab thov. Siab thiab qis; thaum lub formability ntawm cov hmoov txiav txim lub zog ntawm lub billet.

Cov khoom siv tshuaj lom neeg feem ntau yog nyob ntawm cov tshuaj purity ntawm cov ntaub ntawv raw thiab txoj kev milling. Cov ntsiab lus ntawm cov pa oxygen ntau dua yuav txo qhov kev ua tau zoo, lub zog loj thiab cov khoom siv ntawm cov khoom siv sintered, yog li feem ntau ntawm cov txheej txheem ntawm cov hmoov metallurgy muaj qee cov kev cai ntawm qhov no. Piv txwv li, cov pa oxygen cov ntsiab lus ntawm cov hmoov yog 0.2 feem pua ​​​​rau 1.5 feem pua, uas yog sib npaug rau cov ntsiab lus oxide ntawm 1 feem pua ​​​​rau 10 feem pua.
