In the modern industrial field, cemented carbide has become the core material for mechanical processing, mining, oil drilling, and other industries due to its high hardness, wear resistance, and red hardness. However, in practical applications, cemented carbide tools and parts often fail prematurely due to wear, chipping, and thermal cracking, which not only increases production costs but also affects production efficiency and product quality.
1. Thaum hnav tsis muaj cuab yeej ua haujlwm
(I) ua rau
Kev hnav ntawm cov kev hnav khaub ncaws carbide tsuas yog ua kom muaj kev hnav khaub ncaws, thiab cov tawv ncauj ua ke ntawm cov khoom noj khoom haus, khawb av tsis zoo nkauj Ua rau cov khoom poob . cov khoom sib txawv ntawm cov khoom noj, thiab cov khoom ua haujlwm ntawm cov khoom noj kom zoo nkauj rau cov tshuaj lom neeg tshuaj rau saum npoo ntawm cemented carbide nyob rau hauv qhov kev txiav txim ntawm kev ua yeeb yam ntawm kev sib txhuam thiab nrawm ntawm cov khoom {{}
(II) cov ntsiab lus
① Cov txheej txheem txheej txheem saum npoo: ib txheej ntawm cov khoom siv hluav taws xob siab, pvd) thiab lwm txoj kev tso tseg carbide (pervd) thiab lwm yam kev ua kom zoo nkauj (CT) Qhov tshwm sim ntawm cov ntoo muaj abrasive thiab cov nplaum hnav, thiab tib lub sijhawm txhim kho kev pheej hmoo carbide ntxig thiab txo qhov kev pheej hmoo ntawm corrosion hnav {}}
② Txhim kho cov kev txwv: kev hloov kho tsim nyog ntawm kev ua cov tsis muaj xws li kev txiav ceev, thiab txiav kev ua kom txo qis ntawm cov cemented carbide {}}
③ Xaiv cov roj nplua nyeem zoo: xws li cov roj nplua nyeem siab, tuaj yeem tsim cov khoom ua kom zoo nkauj thiab cov khoom siv ua kom sov thiab cov khoom siv hluav taws xob kom txo qis huv siding .
2. fipping chipping tsis ua haujlwm
(I) ua rau
Breakage hais txog kev ua yeeb yam me me lossis cov qauv sib txawv ntawm kev ua kom tau yooj yim, muaj cov khoom sib txawv ntawm cov kab mob tsis sib xws
(II) cov ntsiab lus
① Txhim kho qhov zoo ntawm kev tso cai carbide: nruj tswj cov txheej txheem ntawm cov khoom, thiab nruj me ntsis, tawv tawv, thiab khoov zog {}}
② Cov khoom siv thev naus laus zis thiab tsim kho kom nruj thiab siv lub zog ntawm lub cev, txo qis ntawm lub cuab yeej lub cev, thiab tsis txhob chipping vim yog lub cev deformation.
③ tswj cov txheej txheem kev ua tiav: ua ntej ua tiav, zoo li kev sib tw ua haujlwm kom tsis txhob muaj cov kev cai los txo cov kev cai ntawm cov cuab yeej .
3.} thermal tawg kev ua haujlwm tsis ua haujlwm
(I) ua rau
Thermal tawg txog qhov tsis ua hauj lwm ntawm kev ua kom muaj kev ntxhov siab ntawm cov cuab yeej thoj ni} Thaum lub zog ua kom muaj zog tshaj tawm ntawm cov cuab yeej thermal, thaum lub zog ua haujlwm kub tshaj,} Ib qho ntxiv, carbide muaj cov thermal tsis zoo conductivity, thiab nws yog qhov nyuaj rau cov cua sov kom sai sai, uas tseem yuav ua rau lub zog ntawm cov cua tawg tawg {}}
(II) Kev daws
Txhim kho cov txheej txheem txias: Siv cov khoom siv cua txias ua kom muaj qhov kub thiab txias rau cov khoom siv kom zoo dua qub
Xaiv cov cemented carbide nrog cov cua sov zoo: piv txwv li lub zog ua kom zoo dua qub, thiab cov oxidation tsis kam lees paub, thiab muaj peev xwm tiv taus cov pa hluav taws xob ntxiv, thiab muaj peev xwm ua tau zoo dua qub (NB)
Kev ua kom zoo thev naus laus zis: Siv cov thev naus laus zis tsim nyog los txo cov txheej txheem ntawm cov cuab yeej kom tsis txhob muaj, siv ntu ntev kom tau txias .
Tag
Hauv cov ntawv thov engineering, cov engineers yuav tsum tau siv ntau yam kev pabcuam uas tsis muaj kev ua tiav rau cov neeg siv khoom raws li cov neeg siv khoom lag luam zoo tshaj plaws thiab muaj cov lus nug txog cov lus qhia no cov ntsiab lus no lossis xa khoom lub sijhawm, tsis txhob yig tau txais hauv kev sib cuag nrog peb ntawm {{0} . peb tos ntsoov rau koj cov lus .
