Daim ntawv thov ntawm nanodiamonds nyob rau hauv daim teb ntawm abrasives thiab kev sib tsoo cov cuab yeej

Dab tsi yog nanodiamond?

Nanodiamonds yog ib hom ntawm tsis - nws yog xim hlau atoms, uas muaj cov yam ntxwv xws li Superhard, thiab biocompatibility. Lawv tuaj yeem npaj tau los ntawm ntau yam txheej txheem xws li siab- Lub Plawv Cov Lus Qhia (sp} cov khoom siv carbon

Cov khoom siv no tau siv dav hauv kev lag luam thiab cov hlau txheej txheem: Raws li cov hlau txheej ntxiv, nws tuaj yeem ua rau lub neej ntawm 1-9 zaug thiab txo cov tuab tuab los ntawm ntau dua 50%; Qhov tseem ceeb txhim kho hauv cov khoom noj lub cev qhuav dej kom zoo thiab cov pa oxygen txo cov tshuaj tiv thaiv kev hloov pauv ntawm Heteratory; Raws li cov roj nplua nyeem ntxiv, nws txo cov kev sib txhuam tsis yog 30-40%. Siv nyob rau hauv aerospace teb hniav hniav hniav hniav hniav hniav hniav hniav thiab cov khoom siv rau cov chaw ua kom muaj kev tiv thaiv thiab nkees ua yeeb yam. Hauv cov teb kho mob, nws yog siv los ua cov ntawv nqa tshuaj thiab tshuaj lom fluorescent rau cov qog ua haujlwm kho thiab hauv Vivo cov duab.

Kev tshawb fawb tau pom tias cov khoom siv tuaj yeem ua kom zoo los ntawm kev tswj hwm cov lus qhia: Boron, nitrogen, thiab phosphorization detio: thiab phosphorization dopified Tus qauv hybrid tsim thaum lub theem hloov kev hloov ua rau Anomalous tsis yog monotonic hloov pauv hauv thermal conductivity. Kev txhim kho cov khoom siv txuas ntxiv nthuav lawv cov khoom siv daim ntawv thov, xws li cov khoom siv kho mob uas ua ke nrog cov khoom siv 53GMA Hardness thiab Graphite Qib Tshaj Tawm

 

Daim ntawv thov ntawm nanodiamonds nyob rau hauv daim teb ntawm abrasives thiab kev sib tsoo cov cuab yeej

NANO lub pob zeb diamond feem ntau yog siv nyob rau hauv lub teb ntawm abrasives thiab kev sib tsoo cov cuab yeej ua ke nrog kev tsim cov khoom siv ntawm kev hloov pauv ntawm 6000} 7000kg / mm2. Yuav siv tau los ua cov ntaub ntawv mos lossis cov ntaub ntawv loj, nrog cov khoom siv ntsug heev. Yog tias cov pa roj carbon tau ua ntej loj hlob los yog pob zeb diamond micro synthesized los ntawm lub siab ntawm lub zog ntawm 10 {} 12 GPA tuaj yeem mus txog qib ntuj ntawm lub ntuj lub ntsej muag muaju. Kev siv lub laum hauv cov pob zeb high-zog ua tau tuaj yeem ua tiav lossis tshaj qhov kev ua tau zoo ntawm CB - 30) polycrystalline cov ntaub ntawv. Thaum siv NANA pob zeb diamond raws li ib qho kev sib xyaw ntawm cov khoom siv pob zeb diamond los ua ob npaug, thiab lub zog compressed, thiab lub zog compressived tuaj yeem nce los ntawm 1.7 GPA rau 2.2 GPA. Lub cev sintered no tuaj yeem siv ua qhov txiav rau cov khoom laum.
