Cemented carbide yog hais txog cov khoom siv hlau uas siv cov hlau hloov pauv raws li qib kev sib txuas thiab yog tsim los ntawm cov hmoov metallurgy. Cemented carbide cov khoom siv hlau refractory tebchaw ua cov matrix. Lawv tau dav siv hauv tsheb, kho mob, tub rog, tiv thaiv lub tebchaws, aerospace, thiab aviation. Nws muaj ntau yam kev siv hauv lwm qhov chaw. Piv nrog rau lwm cov ntaub ntawv, cov khoom siv cemented carbide yog hnav-resistant thiab ruaj, muaj thermal conductivity zoo, thiab muaj zog corrosion kuj. Lawv tuaj yeem siv rau ntau yam kev ua haujlwm ib puag ncig, muaj lub neej ua haujlwm ntev, thiab muaj txiaj ntsig zoo. Lawv tuaj yeem txo cov khoom hloov pauv thiab txo cov nqi lag luam. Txhim kho kev ua haujlwm.
Raws li kev siv cov xwm txheej, YT hom carbide yog qhov tsim nyog rau kev sib hloov, ntxhib kev npaj, ib nrab ua tiav kev npaj, ntxhib milling thiab drilling ntawm qhov chaw tsis tu ncua hauv kev sib cuam tshuam ntawm cov ntu tsis sib xws ntawm carbon steel thiab hlau alloy; YG hom nyuaj alloy Cov alloy yog tsim rau ntxhib tig thaum nruam txiav ntawm cam khwb cia hlau, tsis-ferrous hlau thiab lawv cov alloys thiab cov ntaub ntawv uas tsis yog-hlau, semi-tiav thiab xov tig thaum lub sij hawm intermittent txiav, thiab lwm yam.
Tungsten cobalt cemented carbide (YG hom cemented carbide) yog hais txog cov hlau uas muaj tungsten carbide raws li cov theem nyuaj thiab nws yog xim hlau cobalt raws li qib binder. Cov qib siv feem ntau yog YG6, YG8, YG20, thiab lwm yam. Ntawm lawv, Y yog tus pinyin thawj tsab ntawv nyuaj, thiab G yog tus pinyin thawj tsab ntawv ntawm cobalt, yog li cov tungsten alloy yog hu ua YG. luv luv, thiab tus lej hauv qab no sawv cev rau feem pua ntawm cov ntsiab lus cobalt nruab nrab. Los ntawm kev pom kev ua tau zoo, YG carbide muab cov txiaj ntsig zoo ntawm tungsten carbide thiab cobalt, uas yog qhov tseem ceeb ntawm kev ua haujlwm siab, zoo thermal conductivity, zoo cuam tshuam toughness, siab dabtsi yog khoov lub zog thiab zoo heev txiav kuj. Lub cev ntsuas ntawm ntau hom ntawm YG carbide sib txawv. Piv txwv li, qhov ceev ntawm YG6 yog 14. Qhov ceev ntawm YG8 yog 14.5-14.9g/cm3, thiab hardness yog 89HRA. , khoov zog 1500MPa. Nyob rau hauv tej yam kev mob, raws li cov ntsiab lus cobalt nce, lub flexural zog, compressive zog thiab toughness ntawm cov hlau yuav zoo dua, thaum lub ceev thiab hardness yuav qis dua. Yog li ntawd, YG8 thiab YG20 yuav zoo dua dabtsi yog khoov lub zog, compression kuj, thiab cuam tshuam tsis kam tshaj YG6. Cov neeg siv khoom tuaj yeem xaiv qib ntawm cov khoom siv cemented carbide raws li lawv cov kev xav tau thiab kev siv.
