Cov khoom siv feem ntau siv hauv cov cuab yeej Carbide

The Most Common Binder Material Used in A Carbide Tool

Cov khoom siv feem ntau siv hauv cov cuab yeej carbide yog cobalt. Cobalt yog dav siv raws li lub binder theem nyob rau hauv cemented carbide compositions vim nws cov khoom uas ntxiv rau cov hard carbide hais. Cobalt ua haujlwm ua tus neeg sawv cev uas tuav cov tungsten carbide nplej ua ke, tsim cov khoom muaj zog thiab ruaj khov tsim nyog rau kev txiav, drilling, thiab lwm yam kev siv tshuab.


Cobalt muaj ntau yam tseem ceeb hauv cov cuab yeej carbide:


1. Lub zog thiab Toughness: Cobalt muab lub zog thiab toughness rau cov carbide muaj pes tsawg leeg, txhim khu lub zuag qhia tag nrho durability thiab hnav tsis kam ntawm lub cuab yeej.


2. High-Temperature Stability: Cobalt muaj qhov kub thiab txias ruaj khov, tso cai rau cov cuab yeej carbide tswj nws cov hardness thiab lub zog txawm tias qhov kub siab ua haujlwm tau ntsib thaum lub sijhawm ua haujlwm.


3. Chemical Inertia: Cobalt nthuav tawm cov tshuaj inertness, uas pab tiv thaiv cov tungsten carbide nplej los ntawm cov tshuaj tiv thaiv nrog cov khoom siv ua haujlwm lossis txiav cov kua dej, ua kom lub neej ntev.


4. Bonding Agent: Cobalt ua raws li ib tug binder uas tuav cov tungsten carbide nplej ua ke, pab rau cov qauv kev ncaj ncees thiab kev ua tau zoo ntawm cov cuab yeej carbide.


Thaum cobalt yog cov khoom siv feem ntau siv hauv cov cuab yeej carbide, muaj lwm cov ntaub ntawv khi xws li npib tsib xee, hlau, thiab lwm yam khoom siv hauv cov ntawv tshwj xeeb los kho cov khoom ntawm cov cuab yeej carbide kom tau raws li cov kev xav tau tshwj xeeb.


Thaum cov khoom sib txuas xws li npib tsib xee, hlau, thiab lwm yam khoom siv hloov


Cov ntaub ntawv sib khi zoo li npib tsib xee, hlau, thiab lwm yam khoom siv yog siv rau hauv cov cuab yeej alloy hauv cov xwm txheej tshwj xeeb uas lawv cov khoom zoo dua rau cov ntawv thov lossis cov kev xav tau. Nov yog qee qhov xwm txheej thaum lwm cov ntaub ntawv sib txuas yuav nyiam dua cobalt hauv kev ua cov cuab yeej alloy:


1. Corrosive Environments: Nickel-based binders feem ntau yog siv rau hauv cov cuab yeej alloy rau kev siv qhov twg cov cuab yeej raug corrosive ib puag ncig. Nickel muaj kev tiv thaiv corrosion zoo dua piv rau cobalt, ua rau nws zoo tagnrho rau kev txiav cov dej num uas muaj cov khoom corrosive.


2. Txhim kho Toughness: Hlau yog qee zaum siv los ua cov khoom siv hauv cov cuab yeej alloy los txhim kho toughness. Iron-raws li binders tuaj yeem muab kev txhim kho kev cuam tshuam thiab kev ua haujlwm ntev, uas yog qhov muaj txiaj ntsig zoo hauv cov ntawv thov uas lub cuab yeej raug kev ntxhov siab lossis cuam tshuam.


3. Kev txiav txim siab nqi: Nyob rau hauv cov xwm txheej uas tus nqi yog qhov tseem ceeb, kev siv lwm cov ntaub ntawv xws li hlau los yog lwm yam khoom siv yuav zoo dua qub piv rau cobalt. Qhov no tuaj yeem cuam tshuam rau cov ntawv thov uas qhov txiaj ntsig zoo yog qhov tseem ceeb yam tsis muaj kev cuam tshuam txog kev ua haujlwm ntawm cov cuab yeej.


4. Cov ntawv thov tshwj xeeb: Qee daim ntawv thov tshwj xeeb yuav xav tau cov khoom tshwj xeeb uas ua tiav zoo dua nrog lwm cov ntaub ntawv sib khi. Piv txwv li, cov cuab yeej tungsten carbide nrog kev sib xyaw ntawm cobalt thiab npib tsib xee binders tuaj yeem raug txiav rau cov haujlwm tshwj xeeb uas xav tau qhov sib npaug ntawm cov khoom xws li hnav tsis kam, tawv, thiab kub ua haujlwm.


Los ntawm kev siv cov ntaub ntawv sib txawv xws li npib tsib xee, hlau, thiab lwm yam hauv cov cuab yeej alloy, cov tuam txhab tuaj yeem hloov kho cov yam ntxwv ntawm cov cuab yeej kom haum rau ntau qhov chaw ua haujlwm, cov khoom siv, thiab kev ua haujlwm. Txhua cov ntaub ntawv binder muaj cov txiaj ntsig sib txawv thiab tuaj yeem xaiv cov tswv yim raws li cov khoom xav tau rau ib daim ntawv thov tshwj xeeb.
