Hauv cov ntaub ntawv tsis tu dab tsi, nyuaj thiab cov ntaub ntawv nyuaj thiab cov ntaub ntawv tawv me xws li lub khob iav, ceramics, thiab Quartz tau siv ntau zuj zus. Txawm li cas los xij, lawv lub siab tawv thiab qis nruj ntau zaus ua rau ntug chopp, tawg, thiab lwm yam khoom lag luam tsis zoo thiab ua tau zoo. Cermet pom li nplooj, leveraging lawv cov khoom siv tshwj xeeb thiab tau tshwm sim raws li kev daws teeb meem tseem ceeb rau kev ua tiav "PES TSAWG HLOOV" hauv cov ntaub ntawv nyuaj. Tsab ntawv no rho tawm mus rau hauv cov ntsiab lus qhia tom qab qhov kev sib tawg no.
1. Qhov zoo ntawm cermet cov khoom siv
Cermet, ib qho kev sib xyaw ntawm cov kauj theem metallic (piv txwv li, NI, MO, Tic, Tic, Tic, Tic, Tic, Tic, Tic, Tic, Tricks cov cwj pwm zoo tshaj plaws ntawm ob qho tib si:
Tej yam kev siv hluav taws xob hluav taws xob: muab ultrahligh hardness, excomeal hnav tsis kam, thiab tshuaj lom neeg muaj peev xwm, cuam tshuam thaum kev txiav.
Nws yog xim hlau theem: txhim kho kev nruj (nrawm nyuaj: 8-12 mpa · mais / ²), mitigating tawg tsis ntxhov siab nyob rau hauv kev ntxhov siab.
Qhov kev sib xyaw ua ke zoo ntawm kev sib xyaw ua ke thiab yoog raws li Cermet tuaj yeem txiav cov npoo kev ntxhov siab, tso lub hauv paus rau lub hauv paus kom zoo.
2. Precision ntug kev tsim qauv thiab tsim cov txheej txheem tsim khoom
2.1 Ultra {- Cov npoo dua thiab micro- cov hniav txhuam
Edge thickness: precisely tswj ntawm 0.1-0.3 mm (vs . 0.5}}}}}}}}}}
Micro - hniav hniav geometry: micro {{1} mm: 0.2-0,5 mm) txhim kho cov rog. Piv txwv li, thaum txiav 0.5 hli tuab valience iav, cermet tuaj txo cov ntug chopping mus<0.05 mm, nearing zero-chipping performance.
2.2 High - precision sib tsoo thiab polishing
Nto Roughness: Ua tau RA 0.1-0.2 μm (Daim iav raug ua tiav tiav) ntawm pob zeb sib tsoo thiab tshuaj kho tshuab polishing (CMP).
Cov txiaj ntsig:
- Txo kev sib txhuam thiab ua cua sov (txiav kub:<100°C).
- Ua kom meej meej txiav txoj kev rau cov npoo du (tiaj tiaj tiaj) ± 0.01 mm).
3. Ua kom tiav cov txheej txheem txheej txheem thev naus laus zis
Cermet tej feem ntau yog feem ntau coated nrog kev ua haujlwm zoo xws li TIALN lossis Alcrn, Muab:
Hardness: HV 3000-3500, txhim kho kev coj tsis kam.
Kev sib txhuam qis qis: 0.2-0.4 (vs . 0.6}}}} rau kev nqus dej los ntawm 20-30%.
Thermal stability: withstands kub txog 800℃yam tsis muaj oxidation.
Kev Kawm Kev Kawm: Thaum lub tshuab Ceramic Ceramic Matrix, Alcrn Txheej Cermet tuaj yeem txo qis qhov kev txiav kub los ntawm 30% thiab zoo explowually tshem tawm ntug chipping.
4. Optimized txiav cov kab thiab cov txheej txheem sib xyaw ua ke
Ua tiav Pes Tsawg Chipping yuav tsum tau synergy ntawm hniav hniav ua haujlwm thiab cov txheej txheem tsis sib haum xeeb:
4.1 ceev thiab pub tus nqi
Kev txiav ceev: 10-30 m / min (theem nrab ntau yam kom sib npaug kub thiab ntxhov siab).
Tus Nqi Noj Noj: 50-200 mm / min (qis dua rau cov khoom siv nyuaj / thicker kom txo kev ntxhov siab).
4.2 Cua txias thiab lubrication
Cryogenic huab cua txias: tswj txoj kev txiav kub qis dua 50℃(piv txwv li, rau quartz iav).
Yam tsawg kawg nkaus yog lubrication (MQL): muab xa tawm<10 ml/h of coolant, reducing thermal shock.
Kev Ua Tshwj Xeeb
Cermet muaj pes tsawg leeg: 60-80% tej ntu cub tawg + 20}}}} - 40% metallic phau ntawv.
Txheej thickness: 2-5 μm.
Ntug Chipping tswj:<0.05 mm for optical glass, <0.1 mm for advanced ceramics.
Cermet pom lub taub hau lub zog nyuaj thiab cov khoom siv brittle sib cav los ntawm kev sib haum xeeb kev tshawb fawb, kev ua kom zoo dua qub, thiab ua kom zoo dua qub. Los ntawm Ultra - Cov npoo nyias, lawv ua tiav xoom ntug thaum txhim kho lub neej thiab ua haujlwm tau zoo. Raws li kev lag luam xav tau qhov siab dua hauv Optics, cov teeb meem, thiab tshuab cermet, Cermet yuav muaj kev sib tw sib tw.
