Kev ua tau zoo ntawm pob zeb diamond hniav
Pob zeb diamond inserts muaj cov yam ntxwv ntawm lub zog siab, siab tensile lub zog, zoo tshav kub hloov thiab hnav tsis kam, thiab tuaj yeem tau txais kev ua haujlwm siab thiab ua haujlwm siab thiab ua haujlwm hauv kev nrawm nrawm. Cov yam ntxwv saum toj no ntawm pob zeb diamond hniav yog txiav txim los ntawm lub xeev ntawm pob zeb diamond siv lead ua. Nyob rau hauv pob zeb diamond siv lead ua, plaub valence electrons ntawm carbon atoms tsim daim ntawv cog lus nyob rau hauv ib tug tetrahedral qauv, thiab txhua cov pa roj carbon atom tsim tshuaj bonds nrog plaub nyob ib sab molecules los tsim ib tug pob zeb diamond qauv, uas yog heev sib xyaw thiab tshwj xeeb, thiab yog li ua rau pob zeb diamond yog heev tawv. Vim hais tias cov qauv ntawm cov pob zeb diamond polycrystalline (PCD) yog lub cev calcined ntawm cov pob zeb diamond zoo nrog cov kev xav sib txawv, txawm hais tias tus neeg sawv cev fusion ntxiv, nws lub zog thiab hnav tsis kam tseem qis dua li ntawm ib lub pob zeb diamond. Txawm li cas los xij, vim tias PCD calcined lub cev feem ntau yog anisotropic, nws tsis yooj yim rau tawg raws ib qho kev sib cais.
Lub pob zeb diamond hniav muaj lub phaj thiab lub cev txiav. Sab saum toj phaj yog muab nrog convex grooves raws lub disc-shaped ntug. Muaj ntau cov dovetail grooves sib npaug faib rau sab sauv convex ntug raws lub voj voog, thiab chaotic dovetail convex wedges yog teem rau nruab nrab ntawm ob sab dovetail concave grooves. Ribs yog teem rau ntawm lub hauv paus ntawm tav thiab nruab nrab nplhaib ntawm ntau concave zawj hauv qab, thiab lub sab sauv cutter lub cev yog tsau rau ntawm cov tav uas muaj li ntawm dovetail concave grooves, dovetail convex wedges thiab tav los inhibit calcination.
