Kev txiav txim siab hauv kev xaiv tungsten Carbide

Thaum xaiv tungsten carbide rau ib daim ntawv thov tshwj xeeb, muaj ntau yam tseem ceeb uas yuav tsum tau coj mus rau hauv tus account:

1. Qib: Tungsten carbide tuaj nyob rau hauv ntau qib, txhua tus muaj nws tus kheej muaj pes tsawg leeg thiab cov khoom. Cov qib xaiv yuav tsum ua raws li cov kev cai tshwj xeeb ntawm daim ntawv thov ntawm hardness, toughness, hnav tsis kam, thiab lwm yam tseem ceeb.

2. Hardness: Tungsten carbide paub txog nws qhov tshwj xeeb hardness. Qhov xav tau hardness theem yuav nyob ntawm seb cov khoom raug txiav los yog machined. Cov qib nyuaj yog tsim nyog rau kev txiav cov ntaub ntawv nyuaj, thaum cov qib softer me ntsis yuav nyiam rau cov ntawv thov uas yuav tsum muaj qhov sib npaug ntawm hardness thiab toughness.

3. Txheej: Tungsten carbide tuaj yeem coated nrog lwm cov ntaub ntawv, xws li titanium nitride (TiN) lossis titanium carbonitride (TiCN), txhawm rau txhim kho nws cov kev ua tau zoo thiab ua kom lub neej ntev. Cov txheej txheem tuaj yeem txhim kho lubricity, txo kev sib txhuam thiab hnav, thiab muab kev tiv thaiv ntxiv rau oxidation lossis corrosion.

4. Grain Size: Cov nplej loj ntawm cov khoom siv tungsten carbide cuam tshuam nws cov khoom, suav nrog hardness thiab toughness. Qhov ntau thiab tsawg ntawm cov nplej feem ntau ua rau muaj zog dua tab sis qis dua hardness, thaum coarser grain loj muaj zog ntxiv tab sis txo toughness.

5. Cov Phaj Binder: Tungsten carbide feem ntau yog sib xyaw nrog cov hlau nplaum, xws li cobalt lossis npib tsib xee, uas tuav cov carbide hais ua ke. Lub binder theem cuam tshuam rau tag nrho cov toughness thiab lub zog ntawm tungsten carbide. Qhov feem pua ​​​​ntawm cov ntaub ntawv yuav tsum raug xaiv raws li qhov xav tau sib npaug ntawm hardness thiab toughness rau daim ntawv thov tshwj xeeb.

6. Daim ntawv thov tshwj xeeb: Xav txog cov kev cai tshwj xeeb ntawm daim ntawv thov, xws li cov khoom raug txiav, cov kev txiav txim siab (ceev, pub tus nqi, qhov tob ntawm kev txiav), thiab cov kev sib tw tshwj xeeb lossis kev txwv. Cov yam ntxwv no yuav pab txiav txim siab qhov tsim nyog tungsten carbide qib, txheej, thiab lwm yam kev xav tau rau kev ua haujlwm zoo.

Nws yog ib qho tseem ceeb uas yuav tau sab laj nrog tungsten carbide manufacturers lossis cov kws tshaj lij los xyuas kom meej qhov kev xaiv ntawm tungsten carbide rau ib daim ntawv thov. Lawv tuaj yeem muab kev taw qhia raws li lawv qhov kev paub thiab kev paub dhau los kom ntseeg tau tias qhov txiaj ntsig zoo tshaj plaws.

Thaum xaiv cov qib thiab qib ntawm tungsten carbide, peb yuav tsum xub txiav txim siab nws hardness thiab toughness. Tus nqi ntawm cov ntsiab lus cobalt cuam tshuam li cas rau qhov toughness thiab hardness?Cov ntsiab lus ntawm cobalt nyob rau hauv tungsten carbide ho cuam tshuam nws toughness thiab hardness. Cobalt yog cov khoom siv feem ntau siv hauv tungsten carbide, thiab nws cov feem pua ​​​​ntawm cov khoom muaj pes tsawg leeg tuaj yeem hloov kho kom ua tiav cov khoom xav tau.

Txoj cai ntawm tus ntiv tes xoo: Ntau cobalt txhais tau tias nws yuav nyuaj dua rau kev tawg tab sis nws tseem yuav hnav sai dua.

1. Hardness: Lub hardness ntawm tungsten carbide nce nrog cov ntsiab lus cobalt ntau dua. Cobalt ua raws li cov khoom siv matrix uas tuav cov tungsten carbide hais ua ke. Qhov feem pua ​​​​siab dua ntawm cobalt tso cai rau kev sib khi zoo dua, ua rau muaj qhov hnyav dua thiab nyuaj dua tungsten carbide qauv.

2. Toughness: Lub toughness ntawm tungsten carbide txo nrog ntau dua cobalt ntsiab lus. Cobalt yog cov hlau uas muaj zog dua piv rau tungsten carbide hais, thiab ntau tshaj ntawm cobalt tuaj yeem ua rau cov qauv zoo dua tab sis tsis nruj. Qhov kev ua kom muaj zog ntxiv no tuaj yeem ua rau txo qis, ua rau cov khoom muaj kev cuam tshuam ntau dua rau kev tawg lossis tawg hauv qee yam mob.

Nyob rau hauv cov ntaub ntawv uas hardness yog qhov tseem ceeb yuav tsum tau, xws li txiav cov ntaub ntawv nyuaj, ib tug ntau dua cobalt cov ntsiab lus yog feem ntau nyiam mus rau maximize lub hardness thiab hnav tsis kam ntawm tungsten carbide. Txawm li cas los xij, hauv cov ntawv thov uas muaj qhov hnyav thiab qhov cuam tshuam tsis zoo yog qhov tseem ceeb, xws li thaum cuam tshuam nrog kev cuam tshuam los yog kev hloov pauv sai sai, cov ntsiab lus qis cobalt yuav raug xaiv los txhim kho cov khoom toughness thiab tsis kam rau chipping.

Nws yog ib qho tseem ceeb kom nco ntsoov tias muaj kev sib pauv ntawm hardness thiab toughness thaum kho cov ntsiab lus cobalt. Nrhiav qhov sib npaug yog nyob ntawm qhov kev thov tshwj xeeb thiab cov khoom siv xav tau. Cov neeg tsim khoom thiab cov kws tshaj lij hauv tungsten carbide tuaj yeem muab kev taw qhia txog kev xaiv cov ntsiab lus cobalt uas tsim nyog kom ua tiav qhov xav tau qhov sib npaug ntawm hardness thiab toughness rau ib daim ntawv thov.

Ib lub chaw tsim khoom zoo tungsten carbide tuaj yeem hloov cov yam ntxwv ntawm lawv cov tungsten carbide ntau txoj hauv kev.

Qhov no yog ib qho piv txwv ntawm cov ntaub ntawv zoo los ntawm kev tsim tungsten carbide
