Lub pob zeb diamond puas tuaj yeem tawg nrog rauj?
Txheem
Pob zeb diamond yog cov khoom hnyav tshaj plaws nyob hauv lub ntiaj teb, tab sis txawm tias nrog qhov ntawd, nws tseem tuaj yeem raug cuam tshuam los ntawm rab rauj.
Raws li txoj cai, pob zeb diamond muaj ntau qib ntawm lub zog lossis hardness. Qhov zoo thiab kev ua tiav ntawm cov qauv ntawm lub cubic lattice cuam tshuam rau qib ntawm lub zog. Yog li ntawd, pob zeb diamond muaj cov ntsiab lus tsis muaj zog hauv lawv cov qauv uas tso cai rau lawv tawg nrog rauj.
Koj tuaj yeem tsoo pob zeb diamond nrog rauj raws li hauv qab no:
- Xaiv ib lub pob zeb diamond nrog cov khoom siv sab hauv thiab qhov tsis zoo
- Muab lub pob zeb diamond rau ntawm qhov chaw ruaj khov
- Ntaus nyuaj kom ntaus qhov chaw tsis muaj zog tshaj plaws hauv pob zeb diamond lattice.
Kuv mam li npog ntxiv hauv qab no.
Lub pob zeb diamond puas tuaj yeem tawg nrog rauj?
Toughness yog hais txog lub peev xwm ntawm cov khoom siv los tiv thaiv kev puas tsuaj los ntawm kev cuam tshuam los yog ntog. Tab sis yog, koj tuaj yeem tsoo pob zeb diamond nrog rauj. Cov hauv qab no qhia txog qhov tsis muaj peev xwm ntawm pob zeb diamond kom tawg thiab vim li cas koj tuaj yeem tsoo lawv hnyav nrog rauj.
Pob zeb diamond geometry
Cov qauv pob zeb diamond muaj qhov zoo meej cleavage, uas ua rau nws yooj yim rau tawg yog tias lub tshuab raug coj mus rau qhov chaw raug.
Macroscopic cleavage ntawm lub pob zeb diamond qhia nws cov fragility. Nws yuav tsum raug sau tseg tias hardness thiab lub zog yog qhov sib txawv. Lub pob zeb diamond yog ib qho nyuaj, tab sis lub rauj muaj zog. Txawm li cas los xij, nws tseem nyuaj rau tawg pob zeb diamond nrog rauj, tab sis qhov no yuav yog tib txoj kev tawm yog tias koj tsis muaj pob zeb diamond cutters.
Cov qauv sab hauv muaj cov tshuaj sib xyaw ua ke carbon atoms. Cov pa roj carbon atoms tau teeb tsa symmetrically lossis hauv cov qauv lattice, thiab cov pa roj carbon atoms nyuaj rau rhuav tshem.
Tus naj npawb ntawm atoms rau ib chav tsev ntim
Cov qauv cubic ntawm pob zeb diamond lattice yog qhov tshwj xeeb vim nws muaj cov lej loj tshaj plaws ntawm cov atoms thiab cov ntawv cog lus rau ib chav tsev ntim. Qhov no tsim lub hauv paus ntawm pob zeb diamond hardness. Lub cubic lattice tsub kom lub immobility ntawm carbon atoms.
Yuav ua li cas tawg pob zeb diamond nrog rauj
Raws li tau hais los saum toj no, rhuav lub pob zeb diamond nrog rauj zoo tib yam lossis sledgehammer tsis yog ib txoj haujlwm yooj yim, tab sis ua tau.
Siv ntau lub zog los tsim kom muaj zog txaus los tawg lub pob zeb diamond. Txwv tsis pub, lub pob zeb diamond yuav nyob twj ywm. Cia peb tawg lub pob zeb diamond.
Kauj Ruam 1: Xaiv lub pob zeb diamond uas yooj yim tawg
Muaj ntau hom pob zeb diamond uas sib txawv ntawm cov hardness lossis hardness. Tenacity txiav txim siab los yog qib kev ruaj ntseg ntawm lub pob zeb diamond, uas yog qhov tseem ceeb hauv kev tawg pob zeb diamond nrog rauj.
Yog li, tau txais lub pob zeb diamond nrog kev suav nrog sab hauv thiab qhov tsis zoo los ua kom koj txoj haujlwm yooj yim dua.
Kauj Ruam 2: Xaiv qhov Nto
Txiav txim los ntawm lub zog ntawm lub rauj thiab lub toughness ntawm lub pob zeb diamond, koj xav tau ib tug nyuaj nto mus ntaus lub pob zeb diamond. Kuv pom zoo kom teem lub pob zeb diamond rau ntawm daim hlau tuab lossis pob zeb. Koj nyem nws.
Kauj ruam 3: Aiming rauj tshuab
Txhawm rau ua kom koj cov kev siv zog ua tau zoo, coj lub tshuab kom siab tshaj plaws yog siv rau qhov tsis muaj zog ntawm lub pob zeb diamond sab hauv lattice.
Nco tseg: Khaws lub pob zeb diamond tseem txawm tias tom qab raug ntaus nrog rauj. Raws li qhov xav tau, lub tshuab rauj yuav tsis muaj zog yog tias lub pob zeb diamond plam los ntawm rauj tshuab. Clamp lub pob zeb diamond raws li kev pom zoo, lossis siv lwm txoj kev ntawm koj qhov pov tseg kom ntseeg tau tias lub pob zeb diamond ruaj khov.
Cov lus nug nquag nug
Puas yog tag nrho cov pob zeb diamond muaj lub zog thiab tawv?
Tsis muaj. Qhov zoo thiab zoo tag nrho ntawm cov qauv ntawm lub cubic lattice ntawm pob zeb diamond txiav txim siab hardness thiab lub zog. Tab sis qhov zoo ntawm carbon-carbon bonds txawv vim huab cua yam xws li kub. (1)
Dab tsi yog qhov txawv ntawm hardness thiab toughness ntawm pob zeb diamond?
Hardness qhia txog qhov raug ntawm cov khoom rau khawb. Nyob rau hauv sib piv, lub zog los yog toughness ntsuas qhov yooj yim ntawm ib yam khoom rau tsis ua hauj lwm. Yog li, cov pob zeb diamond yog qhov nyuaj heev (yog li ntawd lawv tau siv los khawb lwm cov ntaub ntawv yam tsis muaj qhov nqaij tawv), tab sis tsis muaj zog heev - yog li lawv tuaj yeem tawg nrog rauj.
