Lub cev muaj zog ntawm tungsten carbide

Tungsten carbide, tseem hu ua cemented carbide, yog ib qho ntawm cov khoom siv hauv kev lag luam niaj hnub no. Tungsten carbide productions yeej ib txwm muaj cov khoom ntawm siab hardness, hnav tsis kam, thiab zoo transverse rupture zog. Ntau lub cev muaj zog cuam tshuam los ntawm tus nqi ntawm cobalt thiab carbon, grain loj, thiab porosity.

Qhov ntom

Los ntawm lub cev nam, qhov ceev ntawm tungsten carbide cov khoom yog qhov piv ntawm lawv cov loj rau lawv ntim. Qhov ceev tuaj yeem kuaj nrog kev ntsuas ntsuas. Qhov ceev ntawm tungsten carbide tuaj yeem cuam tshuam los ntawm qhov loj thiab qhov ntim ntawm tungsten carbide. Qhov ntawd txhais tau tias txhua yam uas tuaj yeem cuam tshuam qhov loj lossis qhov ntim tuaj yeem cuam tshuam qhov ntom.

Tus nqi ntawm lawv tuaj yeem cuam tshuam qhov ntom ntawm tungsten carbide. Qhov ntom ntawm cobalt loj dua qhov ntom ntawm carbon. Yog li qhov ntau cobalt nyob rau hauv tungsten carbide, qhov siab ceev ntawm tungsten carbide yog. Ntawm qhov tsis sib xws, ntau cov pa roj carbon ntau nyob hauv tungsten carbide, qhov qis dua ntawm tungsten carbide. Porosity kuj tuaj yeem cuam tshuam qhov ntom ntom. High porosity ua rau tsawg ntom.

Hardness

Txhawm rau txiav txim siab ntawm cov khoom siv hardness yog tib yam li nws hnav tsis kam. Cov khoom lag luam tungsten carbide nrog lub siab tawv tuaj yeem tiv taus qhov cuam tshuam thiab hnav zoo dua, yog li nws tuaj yeem ua haujlwm ntev dua.

Raws li ib tug bonder, tsawg cobalt ua rau zoo hardness. Thiab qis carbon yuav ua rau tungsten carbide nyuaj. Tab sis decarbonization tuaj yeem ua rau tungsten carbide yooj yim rau kev puas tsuaj. Feem ntau, nplua tungsten carbide yuav ua rau nws hardness.

Transverse rupture zog

Transverse rupture lub zog yog lub peev xwm ntawm tungsten carbide los tiv thaiv dabtsi yog khoov. Tungsten carbide nrog zoo dua transverse rupture lub zog yog qhov nyuaj rau kev puas tsuaj nyob rau hauv kev cuam tshuam. Fine tungsten carbide muaj zog dua transverse rupture. Thiab thaum cov khoom ntawm tungsten carbide faib tusyees, lub transverse zoo dua, thiab tungsten carbide tsis yooj yim rau kev puas tsuaj.

Tsuas yog peb lub cev lub cev no, tseem muaj ntau dua peb yuav tsum paub, thiab lawv tuaj yeem sim nrog cov tshuab.

Cov neeg ua haujlwm kuaj xyuas zoo ib txwm tshuaj xyuas cov qauv metallographic nyob rau hauv lub tshuab ntsuas metallurgical. Thaum tshaj cobalt concentrates ntawm ib cheeb tsam, nws yuav tsim ib lub pas dej cobalt.

Peb tuaj yeem paub tus nqi ntawm cobalt los ntawm kev sim cov hlau nplaum cobalt nrog lub cobalt magnetic tester. Thiab lub zog coercive teb kuj tuaj yeem sim nrog tus coerciver.

Los ntawm cov khoom siv lub cev no, nws pom tseeb tias tungsten carbide muaj ntau yam khoom thiab qhov zoo rau kev tsuas, tho txawv, txiav, thiab khawb.

Yog tias koj xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb ntawm tus lej xov tooj lossis xa ntawv nyob sab laug, lossis Xa Peb Xa Ntawv hauv qab ntawm nplooj ntawv no.
