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 tshuaj lub cev.

Cov txheej txheem tshuab tuaj yeem muab faib ua: mechanical crushing thiab atomization;

Physicochemical txoj kev tau muab faib mus rau hauv: electrochemical corrosion method, txo txoj kev, chemical method, txo-chemical method, vapor deposition method, kua deposition method thiab electrolysis method.Ntawm lawv, feem ntau siv yog txoj kev txo qis, atomization method thiab electrolysis method.

2. Cov hmoov yog tsim rau hauv ib qho kev sib cog lus ntawm qhov yuav tsum tau ua.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 pressureless molding.Compression molding yog feem ntau siv hauv compression molding.

3. Sintering ntawm briquettes.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-component system sintering.Rau cov khoom theem sintering ntawm chav tsev thiab cov khoom siv sib xyaw ua ke, qhov kub ntawm sintering yog qis dua qhov melting point ntawm cov hlau thiab alloy siv;rau cov kua-theem sintering ntawm ntau cov khoom siv, qhov kub ntawm sintering feem ntau qis dua qhov melting point ntawm refractory tivthaiv thiab siab dua li ntawm fusible tivthaiv.Melting point.Ntxiv nrog rau qhov zoo tib yam sintering, kuj tseem muaj cov txheej txheem sintering tshwj xeeb xws li xoob sintering, immersion method, thiab kub nias txoj kev.

4. Kev ua haujlwm tom qab ntawm cov khoom.Kev kho mob tom qab sintering tuaj yeem siv ntau txoj hauv kev 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 hauv xyoo tas los no, qee cov txheej txheem tshiab xws li dov thiab forging kuj tau siv rau kev ua cov hmoov metallurgy cov ntaub ntawv tom qab sintering, thiab tau ua tiav cov txiaj ntsig zoo.
