Pob zeb diamond tseem hu ua "pob zeb diamond", uas yog thawj lub cev ntawm qhov peb nquag hu pob zeb diamond. Nws yog cov ntxhia muaj kev sib xyaw ntawm cov roj carbon monanter thiab yog ib feem ntawm cov roj carbon monanter. Pob zeb diamond yog qhov nyuaj tshaj plaws uas muaj tshwm sim hauv qhov xwm txheej, yog li muab piv nrog carbide, uas nyuaj dua?
Coob tus neeg paub tias tungsten carbide yog qhov nyuaj, thiab cov khoom tiav los ntawm tungsten carbide loj hlob zoo heev, ruaj khov thiab hnav tsis kam. Coob tus neeg tsis muaj lub tswv yim ntau txog kev tawv tawv ntawm cov khoom sib txawv, tsuas yog paub tias pob zeb diamond, yog li tungsten carbide yog twv yuav raug hu tsis li nyuaj li pob zeb diamond.
Txawm hais tias Tupbide tsis nyuaj li pob zeb diamond, tab sis ntawm qhov nyuaj, nws tseem muaj qhov nyuaj ntawm 1000 ° C. Nws belongs rau lub hardness qeb ntawm cov khoom, los ntawm cov lus nug uas peb paub tias lub pob zeb tawv tawv ntawm lub pob zeb diamond yog 10 txog 9,5, thiab lub mohs hardness yog qhov siab tshaj plaws ntawm lub pob zeb diamond ntawm pob zeb diamond.
Txawm hais tias Tungsten carbide yog tsis nyuaj li pob zeb diamond, xws li nws lub cev muaj peev xwm ncav cuag ob zaug ntawm cov hlau, thiab cov tub ntxhais hluas tus moda yog li 530-700 GPA, uas yog kuj yog ob zaug ntawm cov hlau.
Nws yog qhov meej meej vim tias lub siab tawv ntawm tungsten carbide thiab zoo heev ntxiv rau hauv aerospace, roj thiab roj, tshuaj kev lag luam, siv Machinery thiab lwm yam teb.
