Txoj Cai Ntawm Pob Zeb Diamond Surface Metallization

Txij li thaum ancient sij hawm, pob zeb diamond tau suav hais tias yog ib qho tseem ceeb heev ornaments. Txawm li cas los xij, nrog kev txhim kho ntawm cov cuab yeej siv niaj hnub no, cov khoom siv tshwj xeeb, thermal thiab hluav taws xob ntawm pob zeb diamond tau maj mam excavated, tig nws los ntawm cov txheej txheem yooj yim mus rau cov khoom siv tseem ceeb.

 

Tab sis txawm hais tias lub pob zeb diamond nws tus kheej zoo npaum li cas, nws yuav nyuaj rau suab ib leeg --- vim hais tias cov particle loj ntawm hluavtaws pob zeb diamond yog me me uas yuav luag txhua daim ntawv thov yuav tsum tau siv lead ua bonding los yog implantation rau hauv substrate. Txawm li cas los xij, pob zeb diamond muaj lub zog sib cuam tshuam nrog ntau cov hlau, ceramics, thiab lwm yam, yog li lub zog sib txuas ntawm pob zeb diamond thiab matrix tsis zoo thiab pob zeb diamond yooj yim poob thaum ntxov.

 

Pob zeb diamond nto metallization yog kev siv cov cuab yeej kho mob saum npoo rau cov hlau nplaum ntawm cov pob zeb diamond, kom nws qhov chaw muaj cov khoom zoo li hlau lossis hlau. Lub metallized nto muaj peb txheej ntawm cov ntaub ntawv, los ntawm sab nraud mus rau sab hauv, raws li nram no:

Thawj txheej yog txheej hlau, uas tuaj yeem ua rau lub pob zeb diamond nto nrog ntau yam tshiab, xws li thermal conductivity zoo heev;
Cov txheej thib ob yog txheej txheej alloying, uas yog tsim los ntawm carbide thiab hlau qauv;
Qhov thib peb txheej yog txheej carbide, uas feem ntau yog ntau pua mus rau phav phav angstroms tuab thiab tuaj yeem txuas ruaj khov rau saum npoo ntawm pob zeb diamond hais. Nws yog tus yuam sij rau saum npoo metallization ntawm pob zeb diamond hais. Nws feem ntau yog tsim los ntawm cov hlau nrog zoo wettability nrog pob zeb diamond, xws li Ti, W, Cr, V, thiab lwm yam. Cov ntsiab lus no tuaj yeem hnov ​​​​mob pob zeb diamond ntawm qhov kub thiab txias los tsim cov carbide ruaj khov. Nws tuaj yeem tsis tsuas yog muaj cov tshuaj zoo sib xyaw nrog pob zeb diamond, tab sis kuj cais nws txoj kev sib cuag nrog oxygen los tiv thaiv nws los ntawm oxidized ntawm qhov kub thiab txias.
