PCD cuab yeej yog ua los ntawm polycrystalline pob zeb diamond riam taub hau thiab carbide matrix los ntawm kev kub siab thiab siab sintering. Nws tuaj yeem tsis tsuas yog muab kev ua si tag nrho rau qhov zoo ntawm kev ua haujlwm siab, siab thermal conductivity, tsis tshua muaj kev sib txhuam coefficient, qis thermal expansion coefficient, me me affinity nrog hlau thiab tsis-hlau, siab elastic modulus, tsis muaj cleaving nto, isotropic, tab sis kuj coj mus rau hauv tus account lub siab zog ntawm hard alloy.
Thermal stability, cuam tshuam toughness thiab hnav tsis kam yog lub ntsiab kev ua tau zoo ntawm PCD. Vim tias nws yog feem ntau siv nyob rau hauv qhov kub thiab txias ib puag ncig, thermal stability yog qhov tseem ceeb tshaj plaws. Txoj kev tshawb no qhia tau hais tias qhov thermal stability ntawm PCD muaj kev cuam tshuam zoo rau nws cov hnav tsis kam thiab cuam tshuam rau qhov hnyav. Cov ntaub ntawv qhia tau hais tias thaum qhov kub siab tshaj 750 ℃, qhov hnav tsis kam thiab cuam tshuam qhov hnyav ntawm PCD feem ntau txo los ntawm 5% -10%.
Lub xeev crystal ntawm PCD txiav txim siab nws cov khoom. Nyob rau hauv microstructure, carbon atoms tsim covalent daim ntawv cog lus nrog plaub atoms nyob ib sab, tau cov qauv tetrahedral, thiab tom qab ntawd tsim cov atomic siv lead ua, uas muaj zog orientation thiab binding quab yuam, thiab siab hardness. Lub ntsiab Performance indexes ntawm PCD yog raws li nram no: ① hardness ncav cuag 8000 HV, 8-12 zaug ntawm carbide; ② thermal conductivity yog 700W / mK, 1.5-9 zaug, txawm tias siab dua PCBN thiab tooj liab; ③ kev sib txhuam coefficient feem ntau tsuas yog 0.1-0.3, tsawg dua 0.4-1 ntawm carbide, txo qhov txiav quab yuam; ④ thermal expansion coefficient tsuas yog 0.9x10-6-1.18x10-6,1 / 5 ntawm carbide, uas tuaj yeem txo thermal deformation thiab txhim kho kev ua haujlwm raug; ⑤ thiab cov khoom tsis yog xim hlau tsis tshua muaj kev sib raug zoo los ua cov nodules.
Cubic boron nitride muaj zog oxidation tsis kam thiab tuaj yeem ua cov ntaub ntawv muaj hlau, tab sis qhov hardness yog qis dua ib lub pob zeb diamond, kev ua haujlwm qeeb thiab kev ua haujlwm tsawg. Ib qho siv lead ua pob zeb diamond muaj siab hardness, tab sis lub toughness tsis txaus. Anisotropy ua rau nws yooj yim rau dissociation raws (111) nto nyob rau hauv kev cuam tshuam ntawm sab nraud quab yuam, thiab kev ua hauj lwm efficiency yog txwv. PCD yog ib qho polymer synthesized los ntawm micron-loj pob zeb diamond hais los ntawm qee yam. Qhov xwm txheej tsis txaus ntseeg ntawm qhov tsis sib haum xeeb ntawm cov khoom ua rau nws cov macroscopic isotropic xwm, thiab tsis muaj kev taw qhia thiab cleavage nto hauv lub zog tensile. Piv nrog rau ib lub pob zeb diamond ib leeg, cov ciam teb ntawm PCD zoo txo cov anisotropy thiab optimizes cov khoom siv kho tshuab.
1. Tsim cov qauv ntawm PCD cov cuab yeej txiav
(1) Tsim nyog xaiv PCD particle loj
Raws li txoj cai, PCD yuav tsum sim ua kom zoo dua cov nplej, thiab kev faib cov khoom ntxiv ntawm cov khoom yuav tsum zoo ib yam li ua tau kom kov yeej cov anisotropy. Kev xaiv ntawm PCD particle loj kuj muaj feem xyuam rau kev ua haujlwm. Feem ntau hais lus, PCD nrog lub zog siab, zoo toughness, muaj kev cuam tshuam zoo thiab cov nplej zoo tuaj yeem siv rau kev ua tiav lossis super tiav, thiab PCD ntawm cov nplej ntxhib tuaj yeem siv rau kev ua haujlwm ntxhib dav dav. PCD particle loj tuaj yeem cuam tshuam rau kev hnav ntawm lub cuab yeej. Cov ntaub ntawv ntsig txog cov ntsiab lus qhia tau hais tias thaum cov khoom siv raw khoom loj, qhov hnav tsis kam maj mam nce nrog qhov txo qis ntawm cov nplej, tab sis thaum cov nplej loj me me, txoj cai no tsis siv tau.
Cov kev sim cuam tshuam tau xaiv plaub pob zeb diamond hmoov nrog qhov nruab nrab qhov ntau thiab tsawg ntawm 10um, 5um, 2um thiab 1um, thiab nws tau xaus lus tias: ① Nrog rau qhov txo qis ntawm cov khoom siv raw, Co diffuses ntau tus sib npaug; Nrog rau qhov txo qis ntawm ②, qhov hnav tsis kam thiab kub tsis kam ntawm PCD maj mam txo.
(2) Tsim nyog xaiv ntawm cov hniav lub qhov ncauj daim ntawv thiab hniav thickness
Daim ntawv ntawm lub qhov ncauj qhov ncauj feem ntau suav nrog plaub lub qauv: inverted ntug, blunt voj voog, inverted ntug blunt voj voog sib xyaw thiab lub kaum ntse ntse. Lub ntsej muag lub ntsej muag ua rau lub ntsej muag ntse, kev txiav nrawm nrawm, tuaj yeem txo qhov txiav quab yuam thiab burr, txhim kho qhov zoo ntawm cov khoom, yog tsim nyog rau tsawg silicon aluminium alloy thiab lwm yam tsis tshua muaj hardness, uniform non-ferrous hlau xov. Lub obtuse puag ncig qauv tuaj yeem passivate lub qhov ncauj qhov ncauj, tsim R Lub kaum sab xis, tiv thaiv cov hniav tawg, tsim nyog rau kev ua haujlwm nruab nrab / siab silicon aluminium alloy.

Co thiab W sib xyaw hmoov tau siv los ua tus neeg sawv cev sib txuas, thiab kev ua tau zoo ntawm sintering PCD yog qhov zoo tshaj plaws thaum lub synthesis siab yog 5.5 GPa, sintering kub yog 1450 ℃ thiab rwb thaiv tsev rau 4min. SiC, TiC, WC, TiB2, thiab lwm yam ntaub ntawv ceramic. SiC Lub thermal stability ntawm SiC yog zoo dua li ntawm Co, tab sis lub hardness thiab tawg toughness kuj tsawg. Kev txo qis ntawm raw khoom loj tuaj yeem txhim kho hardness thiab toughness ntawm PCD. Tsis muaj nplaum nplaum, nrog graphite lossis lwm cov pa roj carbon monoxide nyob rau hauv qhov kub thiab txias siab kub kub rau hauv nanoscale polymer pob zeb diamond (NPD). Siv graphite ua tus thawj coj los npaj NPD yog qhov xav tau tshaj plaws, tab sis cov hluavtaws NPD muaj qhov nyuaj tshaj plaws thiab cov cuab yeej zoo tshaj plaws.
Kev xaiv thiab tswj ntawm ③ nplej
Cov khoom siv raw pob zeb diamond hmoov yog qhov tseem ceeb cuam tshuam rau kev ua haujlwm ntawm PCD. Pretreating pob zeb diamond micropowder, ntxiv ib qho me me ntawm cov khoom cuam tshuam qhov txawv txav ntawm pob zeb diamond hais txog kev loj hlob thiab kev xaiv tsim nyog ntawm sintering additives tuaj yeem cuam tshuam kev loj hlob ntawm cov pob zeb diamond txawv txav.
Siab ntshiab NPD nrog cov qauv zoo sib xws tuaj yeem tshem tawm cov anisotropy thiab txhim kho cov khoom siv kho tshuab. Cov nanographite precursor hmoov npaj los ntawm high-zog pob sib tsoo txoj kev tau siv los tswj cov ntsiab lus oxygen ntawm qhov kub thiab txias ua ntej sintering, hloov graphite rau hauv pob zeb diamond hauv qab 18 GPa thiab 2100-2300 ℃, tsim cov lamella thiab granular NPD, thiab lub hardness nce nrog qhov txo ntawm lamella thickness.
④ Kev kho mob lig
Nyob rau tib qhov kub thiab txias (200 ° C) thiab lub sijhawm (20h), cov nyhuv tshem tawm cobalt ntawm Lewis acid-FeCl3 yog qhov zoo dua li cov dej, thiab qhov kev pom zoo ntawm HCl yog 10-15g / 100ml. Lub thermal stability ntawm PCD txhim kho raws li cov cobalt tshem tawm qhov tob nce. Rau coarse-grained kev loj hlob PCD, muaj zog acid kev kho mob tuaj yeem tshem tawm tag nrho Co, tab sis muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm polymer; Ntxiv TiC thiab WC los hloov cov qauv hluavtaws polycrystal thiab sib txuas nrog cov kua qaub muaj zog los txhim kho kev ruaj ntseg ntawm PCD. Tam sim no, cov txheej txheem kev npaj ntawm PCD cov ntaub ntawv yog kev txhim kho, cov khoom toughness yog zoo, lub anisotropy tau zoo heev, tau paub txog kev lag luam ntau lawm, muaj feem xyuam rau industries yog tsim sai heev.
(2) Kev ua haujlwm ntawm PCD hniav
① txheej txheem txiav
PCD muaj siab hardness, zoo hnav tsis kam thiab siab nyuaj txiav txheej txheem.
② vuam txheej txheem
PDC thiab riam lub cev los ntawm cov neeg kho tshuab clamp, kev sib txuas thiab brazing. Brazing yog nias PDC rau ntawm carbide matrix, nrog rau lub tshuab nqus tsev brazing, nqus diffusion vuam, siab zaus induction cua sov brazing, laser vuam, thiab lwm yam. High zaus induction cua sov brazing muaj tus nqi qis thiab siab rov qab, thiab tau siv dav. Qhov vuam zoo yog cuam tshuam nrog cov flux, vuam alloy thiab vuam kub. Vuam kub (feem ntau qis dua 700 ° ℃) muaj qhov cuam tshuam loj tshaj plaws, qhov kub thiab txias siab dhau, yooj yim ua rau PCD graphitization, lossis txawm tias "hluav taws kub hnyiab", uas cuam tshuam ncaj qha rau cov nyhuv vuam, thiab qhov kub qis dhau yuav ua rau lub zog vuam tsis txaus. Lub vuam kub tuaj yeem tswj tau los ntawm lub sijhawm rwb thaiv tsev thiab qhov tob ntawm PCD redness.
