Qhov cuam tshuam ntawm cemented carbide carbon cov ntsiab lus tswj ntawm qhov zoo

Cov ntsiab lus carbon hauvcementedcarbide tau kawm uhu nkauj lub tshuab nqus tsev sintering.Kev tsom xam tau taw qhia tias tag nrho cov ntsiab lus carbon hauv cov khoom siv raw ua lub luag haujlwm txiav txim siab hauv cov ntsiab lus carbon ntawm cov hlau.Tsis tas li ntawd, cov khoom nyuaj hauv cov hmoov nias yog tsim thaum lub sij hawm nias.

Nws tsis yooj yim rau deform thiab crushed thaum lub sij hawm tus txheej txheem, thiab nws yog ib qho yooj yim rau choj, uas ua rau lub tsim ntawm kaw qhov thaum lub sij hawm cov kua theem sintering txheej txheem, uas muaj ib tug ntau dua ntawm cov ntsiab lus ntawm cov pa roj carbon monoxide.tungsten carbide alloy, thaum tus nqi ntawm cov kua nplaum ntxiv muaj qhov cuam tshuam me me rau cov ntsiab lus carbon ntawm covcemented carbide..Raws li sintering kub nce los ntawm 1400 ° C mus rau 1480 ° C, cov ntsiab lus carbon hauv cov hlau ua ntej nce thiab tom qab ntawd txo qis.Thaum lub sintering kub yog 1450 ° C, cov ntsiab lus carbon ncav cuag qhov siab tshaj plaws.

Cov ntsiab lus: cemented carbide;nias: sintering.Nyob rau hauv cov txheej txheem ntau lawm ntawmcemented carbide, cov ntsiab lus carbon muaj qhov cuam tshuam tseem ceeb ntawm WC grain loj, theem qauv thiab cov khoom siv ntawm cemented carbide, thiab cov ntsiab lus carbon hauv cov khoom siv raw, cov kua nplaum ntxiv, nias, thiab sintering yuav cuam tshuam rau cov ntsiab lus carbon.Cov kws tshawb fawb hauv tsev thiab txawv teb chaws tau tshawb fawb ntxiv txog kev sib raug zoo ntawm cov ntsiab lus carbon thiab flexural zog, hardness thiab coercive quab yuam, tab sis tsawg dua ntawm cov ntsiab lus uas cuam tshuam rau cov ntsiab lus carbon.Kab lus no siv lub tshuab nqus tsev sintering los kawm txog cov ntsiab lus carbon hauv cov khoom siv raw., kev cuam tshuam ntawm cov kua nplaum sib xyaw, nias thiab sintering txheej txheem ntawm cov ntsiab lus carbon
