Lub pob zeb diamond polycrystalline compact (pob zeb diamond composite phaj) yog composite matrix, abbreviation PDC.
Nws yog cov khoom siv ua haujlwm tsim los ntawm sintering pob zeb diamond hmoov thiab tungsten carbide substrate nyob rau hauv ultra-siab siab thiab kub kub. Nws ua ke nrog lub siab tawv, hnav tsis kam, thermal conductivity ntawm pob zeb diamond thiab qhov cuam tshuam tsis kam ntawm tungsten carbide, thiab tau siv dav hauv kev hnav khaub ncaws -cov cuab yeej tiv taus xws li roj laum cov khoom thiab cov cuab yeej txiav.
Cov khoom sib xyaw ua ke uas nyias txheej ntawm polycrystalline pob zeb diamond yog adhered thiab sib koom ua ke rau tungsten carbide substrate yog hu ua pob zeb diamond composite sheet, thiab yog denoted li PDC. Cov ntawv pob zeb diamond sib xyaw muaj qhov hnav tsis tshua muaj siab ntawm polycrystalline pob zeb diamond thiab muaj kev cuam tshuam siab ntawm tungsten carbide. Ntxiv mus, cov pob zeb diamond txheej ib txwm muaj peev xwm tswj tau qhov ntse txiav ntug, thiab yog li ntawd zoo heev rau kev siv hauv cov mos mus rau nruab nrab- nyuaj formations hauv roj av thiab geological drilling. Cov ntsiab lus pob zeb diamond hauv cov ntawv sib xyaw yog siab li 99%, yog li qhov hardness thiab hnav tsis kam ntawm cov pob zeb diamond txheej yog siab heev. Nws Nyquist hardness yog (6.5 - 7) × 104 megapascals, thiab ntau dua. Lub thickness yog nyias heev, feem ntau tswj ntawm 0.5 - 1 millimeters. Nws yog vertically soldered mus rau lub laum me ntsis, nrog ib tug ntse txiav ntug thiab ib txwm tuav nws tus kheej -sharpening, thiab tseem hu ua micro- txiav cuab yeej laum ntsis.
Txoj kev txhim kho
1. Polycrystalline pob zeb diamond txheej ua kom tuab, nce los ntawm tsawg dua 1mm mus rau 2-4mm, thiab cov khoom lag luam lifespan kuj txhim kho. Cov roj av sib xyaw pob zeb diamond txheej ntawm Zhengzhou Xinya thiab Henan Yalong tau mus txog 4 hli, sawv cev rau qib siab tshaj plaws hauv Suav teb.
2. Cov pob zeb diamond nplej ua kom zoo dua, thiab kev ua tau zoo ntawm kev hnav tsis kam thiab kev cuam tshuam zoo tuaj.
3. Los ntawm optimizing cov txheej txheem los yog tshem tawm cobalt, ua kom cov cua sov-resistant txheej, thiab lwm yam., lub thermal stability yog zoo dua.
4. Kev ua kom zoo ntawm cov qauv interface txhim kho cov kev ntxhov siab cuam tshuam.
5. Cov khoom lag luam txoj kab uas hla ua kom nce ntxiv, txhim kho kev ua kom zoo dua qub.
6. Cov nyhuv sintering yog txhim kho, txo kev ua haujlwm sib txawv.
7. Cov ntawv tshwj xeeb- zoo li cov ntawv sib xyaw, xws li ntau- pob zeb diamond- txheej cov nplooj ntawv sib xyaw, cov kaus mom hlau- zoo li cov nplooj ntawv sib xyaw, ridge- zoo li cov ntawv sib xyaw, cov ntawv sib xyaw conical, thiab arc- zoo li pob zeb diamond composite sheets, tau tsim los ntawm{7} cov ntawv loj loj Zhuzhou Xinya thiab Henan Yalong. Cov ntaub ntawv pob zeb diamond tshiab no zoo heev txhim kho qhov cuam tshuam ntawm cov pob zeb diamond sib xyaw daim ntawv yam tsis tau hloov pauv qhov hnav tsis kam, thiab tau tuav feem ntau ntawm kev lag luam hauv tsev.
Artificial pob zeb diamond composite sheets nyob rau hauv qeb ntawm super- cov ntaub ntawv nyuaj. Lo lus "super" ntawm no tsis yog tshwj xeeb thiab npog ntau yam. Super- cov ntaub ntawv nyuaj yog cov uas muaj Rockwell hardness siab heev (HR), Brinell hardness (HB), thiab Vickers hardness (HV). HR ntawm 45 # hlau yog 30-60, thiab qhov nyuaj tshaj plaws yog pob zeb diamond. Lub tswv yim no suav nrog ntau yam, suav nrog siab -hardness steel, high-hardness ceramics, dag pob zeb diamond, thiab lwm yam.
Kev ua tau zoo thiab txiav cov yam ntxwv
1. Lub hardness yog HV7500-9000, thib ob tsuas yog pob zeb diamond. Ntxiv mus, nws hardness thiab hnav tsis kam yog zoo ib yam nyob rau hauv tag nrho cov lus qhia thiab tsis tas yuav xaiv cov kev taw qhia. Nws lub zog tau txais kev txhawb nqa los ntawm cov khoom siv tawv tawv tawv, thiab cov khoom sib xyaw ua ke tuaj yeem ncav cuag 1500 Mpa.
2. Nws muaj kev hnav siab heev, nrog rau kev hnav tsis kam uas yog 60-80 npaug ntawm cov alloys nyuaj. Thaum txiav cov ntaub ntawv uas tsis yog-hlau nrog siab hardness (HV> 1500), nws cov cuab yeej siv tau ntev heev.
3. Nws muaj qhov sib txhuam coefficient tsawg. Kev sib txhuam coefficient ntawm pob zeb diamond thiab cov hlau tsis yog -ferrous hlau yog 0.1-0.3, thaum nruab nrab ntawm cov alloys nyuaj thiab cov hlau tsis yog hlau yog 0.3-0.6. Yog li, thaum siv PCD cov cuab yeej, txiav quab yuam thiab txiav kub tuaj yeem txo los ntawm kwv yees li 1/2-1/3.
4. Nws muaj thermal conductivity heev. Lub thermal conductivity ntawm pob zeb diamond yog 146 W / MK, uas yog 1.5-7 npaug ntawm cov alloys nyuaj, thiab tuaj yeem txo qhov kub thiab txias hauv cheeb tsam txiav thiab txhim kho cov cuab yeej siv tau ntev.
5. Lub linear expansion coefficient ntawm pob zeb diamond yog me me (0.9-1.18 * 10(-6) mm / mm. kub), kwv yees li 1/10 ntawm cov hlau dav dav (11 * 10 (-6) mm / mm. kub). Ntxiv mus, vim qhov ntse txiav ntug, qhov txias hardness tshwm sim ntawm lub tshuab ua haujlwm me me, txog 1/3 ntawm cov cuab yeej nyuaj alloy. Yog li ntawd, kev ua haujlwm raug yog qhov zoo.
6. Vim hais tias cov particle loj txoj kab uas hla ntawm lub polycrystalline txheej yog feem ntau yog hais txog 2-5 micrometers, nws txiav ntug sharpness tsis zoo li tej yam ntuj tso pob zeb diamond cuab yeej. Yog li ntawd, qhov kev ua tau zoo yog qis dua li ntawm cov cuab yeej pob zeb diamond, thiab tuaj yeem ncav cuag qhov roughness Ra0.2-0.05 micrometers. Txawm li cas los xij, nws tuaj yeem ua rau cov hniav loj dua rau kev ua haujlwm.
