Qhov cov kev cai los yog Powde Metallurgy
Nyob li cas tshaj kev caij yog cov ntsuam nyob rau hauv lub tsheb, ntawm lub tsheb yeej thiab, ua siab thiab ua tsev, thiab ua siab thiab ua tsev, thiab ua siab thiab ua tsev, thiab ua siab thiab ua tsev, thiab ua siab thiab ua tsev, thiab ua siab thiab ua tsev, thiab ua siab thiab ua tsev, thiab ua siab thiab ua tsev, thiab ua siab thiab ua tsev, thiab ua siab thiab ua tsev, thiab ua siab thiab ua tsev, thiab ua siab thiab ua tsev.
Qhov cov kev cai los yog Powde Metallurgy
1. Powder metallurgy mus rau li noj ntsuam:
Powder metallurgy mus rau li noj ntsuam, suav daim nyob rau hauv ib tug qhov kev ua li cas sib powder metallurgy. Yog li cas qab yeej uas muaj metal nyob rau txog teb chaw, tus iron ore thiab muaj ib tug cov coj cai yog li cas qab yeej uas muaj coke thiab muaj ib tug original furnace, thiab muaj ib tug sponge iron sib siv rau li cas qab yeej uas muaj dispersed iron block, thiab muaj ib tug sponge iron thiab muaj forged rau hauv ib tug cov tsis ntawm instrument. Suav daim nyob rau hauv weapons.
2. Rau li ntawv 19th, thiab muaj casting method thiab muaj re-used:
Thaum ntawm lub ntxhais cov tsis yog luam, rau hauv nyob ntawm rooj 19, cov txhais kev caij kev caij yog kev caij kev caij yog kev caij. Rau hauv tus tswj kev caij kev caij yog kev caij kev caij rau hauv nyob ntawm rooj 19 thiab rooj 20, thaum ntawm cov ntsuam ntxhais thiab ua li cas lwm. Yog los yog kev caij kev caij lawv tau mus rau hauv kev caij kev caij kev caij. Lub cov xovxwm carbide yog ua hauv ib qhov muaj thiab ua hauv ib qhov muaj thiab ua hauv ib qhov muaj.
3. Tau xaiv los ntawm rooj 1930:
Koj 1930, txhais qhov ntsuam metallurgy thiaj lub siab rau hauv sw cov kev pab. Yog cov kev mus tawm ntawv qhov friction metal materials, friction materials, filters, magnetic materials, contact materials, cutting tools, structural materials thiab cov kev pab ib tug tawm ntawm metal powder metallurgy, cov kev kom nyob rau hauv ib tug tshaj ntawm. Rho xav tom, metal powder metallurgy materials yog mus tawm ntawv rau hauv cov kev atomic energy thiab rocket technology.
