Cov txheej txheem txheej txheem ntawm hmoov metallurgy
1. Kev npaj ntawm cov khoom nyoos hmoov. Cov txheej txheem uas twb muaj lawm tuaj yeem muab faib ua ob pawg: cov kev siv tshuab thiab kev siv lub cev. Cov txheej txheem kho tshuab yuav muab faib ua: txoj kev pulverization thiab atomization method; kev qhia lub cev kev siv tshuaj yog ntxiv rau hauv cov txheej txheem: electrochemical xeb txheej txheem, txo txoj kev, tshuaj lom neeg txoj cai, txo-kev cai lij choj tshuaj, vapor deposition txoj kev, kua theem deposition txoj kev thiab txoj kev electrolysis. Ntawm lawv, txoj kev siv dav siv feem ntau yog txo qis, atomization thiab electrolysis.
2. Lub hmoov tsim tau rau hauv qhov me me ntawm qhov xav tau. Lub hom phiaj ntawm txoj kev ua yog tsim lub qhov me me ntawm qee yam duab thiab qhov loj thiab kom muaj qee qhov ceev thiab qhov muaj zog. Cov txheej txheem moulding feem ntau muab faib ua xovxwm molding thiab pressureless molding. Cov feem ntau siv hauv xovxwm molding yog compression molding. Tsis tas li ntawd, 3D tshuab luam ntawv tshuab kuj tseem siv tau rau kev tsim khoom ntawm embryo tawg.
3. sintering ntawm kev cog lus me me. Sintering yog cov txheej txheem tseem ceeb hauv cov hmoov hlau ua haujlwm. Tus tsim ntsuab ces yog sintered mus cuag yam kawg cev nqaij daim tawv thiab cov yam ntxwv. Kev ua txhaum ntau ntxiv muab faib ua hom kab ke sintering thiab cov khoom sib txuam ua ke. Rau cov theem ua haujlwm sintering ntawm chav tsev thiab cov tshuab ua haujlwm ntau, qhov kub siab sintering qis dua qhov nplawm ntawm cov khoom siv hlau thiab alloys siv; rau multiphase kua theem sintering, qhov kub siab sintering feem ntau qis dua qhov chaw melting ntawm qhov refractory tivthaiv, thiab siab dua fusible tivthaiv. Melting taw tes. Ntxiv nrog rau qhov sintering zoo tib yam, muaj cov txheej txheem tshwj xeeb sintering xws li xoob sintering, yaj lub cev, thiab kub nias.
4, kev coj ua tom ntej ntawm cov khoom. Kev kho tom qab ua tsis zoo tuaj yeem nqa tawm nyob rau hauv ntau yam raws li qhov yuav tsum tau ua ntawm cov khoom. Xws li kev ua tiav, kev siv roj ua, kev siv tshuab, kho cua sov thiab daim hlau. Tsis tas li ntawd, nyob rau xyoo tas los no, qee cov txheej txheem tshiab xws li dov thiab forging kuj tau ua ntawv thov rau kev ua cov hmoov hlau cov ntaub ntawv tom qab ua txhaum, thiab tau tiav cov txiaj ntsig tau zoo.
