Plaub theem tseem ceeb ntawm Tungsten Carbide Thaum tshav kub kub kho

Tungsten carbide muaj kev ua tau zoo nrog cov khoom siv zoo heev thiab lub cev, nrog rau kev hnav tsis kam, corrosion kuj, khoov lub zog, torsion zog, thiab lwm yam., dav siv rau kev txiav cov cuab yeej, pwm txias, hnav qhov chaw, thiab lwm yam. Cov theem tseem ceeb ntawm tungsten carbide kev kho cua sov, uas tuaj yeem txhim kho lub cev thiab cov khoom siv ntawm cov tawv tawv.

Cov txheej txheem kho cua sov ntawm tungsten carbide tuaj yeem muab faib ua plaub kauj ruam tseem ceeb.

1. Tshem tawm cov khoom molding thiab pre-sintering

Thaum pib ntawm sintering, tus neeg sawv cev tsim maj mam decomposes lossis evaporates, tsis suav nrog lub cev sintered, tib lub sijhawm, cov neeg ua haujlwm tsim carburize lub sintering, thiab cov pa roj carbon ntau yuav txawv nyob ntawm hom, nyiaj, thiab txheej txheem ntawm sintering. . Cov hmoov av oxide raug txo, thiab hydrogen tuaj yeem txo cov cobalt thiab tungsten oxides ntawm qhov kub thiab txias. Nrog rau cov tshuaj tiv thaiv tsis muaj zog ntawm cov pa roj carbon thiab oxygen, kev sib cuag ntawm cov hmoov hmoov yog maj mam tshem tawm. Cov hmoov hlau sib txuas pib teb thiab recrystallization thiab nto diffusion pib tshwm sim. Thaiv lub zog nce.

2. Theem ntawm cov khoom-theem sintering (800 ° C - eutectic kub)

Nyob rau hauv lub xub ntiag ntawm cov kua theem, ntxiv rau cov txheej txheem ntawm kev txuas mus rau yav dhau los theem, cov khoom-theem cov tshuaj tiv thaiv thiab diffusion yog aggravated nrog ib tug nce nyob rau hauv cov yas ntws, thiab ib tug ntshiab shrinkage tshwm nyob rau hauv lub sintered lub cev.

3. Theem ntawm cov kua-theem sintering (eutectic kub - sintering kub)

Thaum cov kua theem ntawm lub cev sintered tshwm sim, lub compression yog sai sai ua kom tiav, thiab ces ib tug crystallization hloov tshwm sim. Lub koom haum thiab cov qauv ntawm cov carbide yog tsim.

4. Cua txias theem (sintering kub - chav tsev kub)

Nyob rau theem no, cov koom haum thiab theem ntawm tungsten carbide tau txais qee qhov kev hloov pauv hauv ntau yam cua txias, uas ua rau nws muaj peev xwm siv tau qhov no; Thaum tshav kub kub kev kho mob ntawm hard alloy yuav txhim kho nws lub cev thiab txhua yam yam ntxwv.

ZZBETTER mob siab rau nws tus kheej los tsim cov khoom lag luam hauv ntiaj teb thiab cov khoom zoo tungsten carbide. Peb cov khoom tau raug muag rau ntau lub teb chaws thiab cheeb tsam thiab kuj ua kom muaj kev vam meej hauv kev lag luam hauv tsev.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
