Puas yog lub pob zeb diamond zoo tshaj?

Pob zeb diamond yog ib qho nyuaj tshaj plaws cov khoom ntuj hauv ntiaj teb, nrog mohs hardness ntawm 10. Txawm li cas los, hardness ib leeg tsis txiav txim siab seb cov ntaub ntawv yog qhov ntse tshaj plaws. Lub tswv yim ntawm sharpness cuam tshuam nrog ntau dua li hardness; Nws kuj muaj feem cuam tshuam rau kev muaj peev xwm los ua tus ntug zoo thiab tswj hwm nws.

 

Hauv qab no yog cov lus qhia ntxaws ntxaws ntawm qhov tseeb ntawm pob zeb diamond thiab lwm yam khoom siv:

Lub hlawv

• Pob zeb diamond yog qhov nyuaj tshaj plaws paub cov khoom siv ntuj, ua rau nws tau tiv taus khawb thiab hnav. Nws cov hardness tso cai rau nws txiav los ntawm ntau yam tshuaj. Txawm li cas los xij, pob zeb diamond yog heev nkig. Thaum lawv tuaj yeem ua kom zoo rau ib ntug zoo, lawv muaj feem ntau tau tawg lossis tawg raws li kev cuam tshuam, uas muaj kev txwv lawv cov cuab yeej.

 

Aggregated Pob Zeb Diamond Nanorods

• Aggregated Pob Zeb Diamond Nanorods Nanorods, tseem hu ua "Hyperdiamond," yog cov khoom siv hluavtaws tsim hauv chav kuaj. Cov ntaub ntawv no yog me ntsis nyuaj dua li cov khoom lag luam nruab nrab thiab ntau dua hlais dua li Teflon. Nws cov qauv muab nws tshwj xeeb cov khoom siv tshuab, muaj peev xwm ua kom nws sharper tshaj li cov pa pob zeb diamond. Txawm li cas los xij, nws cov ntawv thov cov tswv yim tseem yog tseem tab tom tshawb fawb thiab kev txhim kho.

 

Wurtzite Boron Nitride

• Nyob rau hauv huab siab siab, Wurtzite Boron Nitride tuaj yeem ua nyuaj dua pob zeb diamond. Cov ntaub ntawv no thaum Boron Nitride yog raug rau kev cuam tshuam tam sim ntawd, xws li cov neeg los ntawm lub mos txwv. Nws cov hardness surpasses ntawm pob zeb diamond, hais kom nws kuj tseem muaj cov ntse tshaj. Txawm li cas los xij, nws cov kev siv tswv yim tseem tau tshawb nrhiav.

 

Cov Nanotubes

• Cov pa roj carbon nanotubes yog cylindrical nanostration ua los ntawm cov roj atoms. Lawv ua pov thawj lub zog thiab hardness, nrog qee hom txawm muaj pob zeb diamond thoob plaws hauv tawv tawv. Lawv cov qauv tshwj xeeb muab lawv zoo dua cov neeg kho tshuab, muaj peev xwm ua rau lawv crarper ntau dua pob zeb diamond. Txawm li cas los xij, lawv siv cov cuab yeej siv cov cuab yeej tseem tab tom tshawb nrhiav.

 

Cubic Boron Nitride

• Cubic Boron Nitride (CBN) yog cov khoom siv hluavtaws nrog hardness piv rau pob zeb diamond. Nws feem ntau siv rau kev txiav cov hlau hardened thiab lwm yam khoom tawv. CBN tuaj yeem tswj nws cov ntse nyob hauv cov kub thiab kev ntsuas siab, ua nws txoj kev xaiv tau los rau lub pob zeb diamond nyob rau hauv qee cov kev siv.

 

Cov yam ntxwv ntawm Pob Zeb Diamond

• Kev nyuaj: Diamonds yog cov khoom siv nyuaj tshaj plaws, muaj peev xwm yooj yim ntawm kev khawb yooj yim lwm yam khoom. Cov cuab yeej no ua rau lawv muaj txiaj ntsig zoo rau kev txiav thiab sib tsoo cov ntaub ntawv nyuaj.
• ** Brittleness **: txawm tias lawv hardness, pob zeb diamond yog qhov loj me. Nyob rau hauv kev cuam tshuam, tshwj xeeb tshaj yog los ntawm lub kaum sab xis tshwj xeeb, lawv tuaj yeem tawg lossis tawg. Qhov no brittleness txwv lawv siv hauv cov cuab yeej txiav.
• Tshuaj Muaj Peev Xwm: Pob zeb diamond muaj cov tshuaj ruaj khov zoo thiab tiv taus kev xeb. Lawv tuaj yeem tswj lawv cov ntse hauv ntau qhov chaw ib puag ncig.

 

Piv nrog lwm cov ntaub ntawv

• Aggregated Pob Zeb Diamond Nanorods thiab Wurtzite Boron Nitride: Cov ntaub ntawv no nyuaj dua li kev ua pob zeb diamond thiab tuaj yeem muab cov ntse tshaj. Txawm li cas los xij, lawv cov ntawv thov siv tau tseem tab tom tshawb fawb.
• Cov Nanotubes: Nrog Hardness muaj feem cuam tshuam lub pob zeb diamond, cov pa roj carbon nanotubes kuj tseem yuav tau ci. Lawv siv cov cuab yeej txiav txim siab tseem raug tshawb nrhiav.
• Cubic Boron Nitride: CBN muaj hardness piv rau pob zeb diamond thiab zoo dua thermal ruaj khov thaum kub. Nws feem ntau yog siv los hloov chaw rau pob zeb diamond hauv cov cuab yeej.

 

Hauv cov ntsiab lus xaus, thaum lub pob zeb diamond yog cov khoom siv nyuaj tshaj plaws, nws tsis tas yuav tsum ntse tshaj plaws. Lwm cov ntaub ntawv xws li Aggregated Pob Zeb Diamond Nanorods, Wurtzite Boron Nitride, Carbon Nitride Showit Hardness Thiab Sharet Uas Muaj Sij Hawm Hla Hauv Tej Yam. Txawm li cas los xij, cov ntaub ntawv thov ntawm cov ntaub ntawv no raws li cov cuab yeej tseem tab tom tshawb fawb thiab kev txhim kho. Pob zeb diamond tseem muaj ib qho ntawm cov khoom siv ntse tshaj plaws tab sis tsis yog tsuas yog kev xaiv rau kev ua kom tiav qhov ntsuas tshwj xeeb.
