Alumina (Al₂O₃) yog ib qho ntawm feem ntau siv engineering ceramics hauv kev ntim khoom hluav taws xob, kev tsim khoom semiconductor, hluav taws xob hluav taws xob, thiab kev siv kho mob. Txawm li cas los xij, vim nws qhov hardness siab thiab nkig, kev tsim tawg tseem yog ib qho ntawm cov teeb meem loj tshaj plaws thaum lub sij hawm machining.
Kev tawg tsis yog tsuas yog txo cov khoom lag luam tawm xwb tab sis kuj tseem tuaj yeem cuam tshuam rau lub sijhawm ntev - kev ntseeg siab, tshwj xeeb tshaj yog nyob rau hauv siab -kev ua tau zoo ntawm cov khoom siv hluav taws xob. To taub lub hauv paus ua rau tawg yog qhov tseem ceeb rau kev xaiv cov txheej txheem machining tsim nyog.
Tsab ntawv xov xwm no piav qhia txog peb qhov tseem ceeb ntawm cov kab nrib pleb thaum lub sij hawm alumina ceramic txiav thiab yuav ua li cas UV laser txiav tshuab pab txo cov teeb meem no.
1. Mechanical stress cracks
Mechanical cracks yog feem ntau txuam nrog cov pa machining txoj kev xws li pob zeb diamond saw txiav thiab mechanical dicing.
Tej yam ua rau muaj xws li:
---- Kev pub noj ntau dhau uas ua rau muaj kev txiav txim siab tshaj qhov kev puas tsuaj ntawm cov ceramic.
---- Kev txiav qhov tob tob, ua rau muaj kev ntxhov siab ntau dua thiab tawg tawm.
---- Hnav pob zeb diamond hniav uas hloov los ntawm kev txiav zoo rau cov khoom siv extrusion, ua rau ntug chipping thiab microcracks.
---- Lub zog clamping tsis raug lossis tsis txaus txhawb nqa lub zog ua haujlwm, ua rau muaj kev ntxhov siab thiab deformation.
---- Ntse sab hauv cov ces kaum yam tsis muaj lub vojvoog hloov pauv, qhov chaw muaj kev ntxhov siab hauv cheeb tsam tuaj yeem pib tawg.
Cov kev ntxhov siab ntawm cov tshuab no feem ntau tsim cov microcracks saum npoo uas yuav nthuav tawm thaum lub sij hawm tom qab thermal cycling los yog sib dhos.
2. Kev kub ntxhov siab tawg
Kev ua laser kuj tseem tuaj yeem tsim cov kab nrib pleb yog tias cov khoom siv hluav taws xob tsis raug tswj tau zoo.
Txawm hais tias alumina muaj qhov zoo thermal stability, nws cov thermal conductivity qis dua li cov hlau. Cov cua kub hauv cheeb tsam ntau dhau tuaj yeem tsim qhov kub siab gradients, ua rau muaj kev ntxhov siab thermal.
Tej yam tshwm sim muaj xws li:
---- Ntau dhau laser mem tes zog
---- Tsawg txiav ceev ua rau cov cua sov sib xyaw
---- Loj tshav kub cuam tshuam (HAZ)
---- Tsis txaus pab roj lossis cua txias tsis txaus
---- Cov txheej txheem tsis raug parameter optimization
Piv nrog cov tsoos CO₂ laser txiav,355nm UV laser txiav txo cov teebmeem thermal los ntawm lub zog photon ntau dua thiab qis dua cov khoom siv hluav taws xob, ua rau nws tsim nyog rau precision ceramic ua.
3. Cov khoom siv -Txog Ncua Nrawm Cracks
Qee qhov tawg tuaj ua ntej machining pib.
Tej yam tshwm sim muaj xws li:
---- Residual stresses generated thaum lub sij hawm ceramic sintering
---- Cov khoom tsis sib xws
---- Loj grain loj
---- Internal pores los yog inclusions
---- Lower-purity ceramic cov ntaub ntawv nrog txo cov pob txha toughness
Kev tshuaj xyuas cov khoom nkag thiab ruaj khov ceramic zoo yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo ib yam.
Yuav ua li casUV Laser TxiavYuav txo qhov tawg ntawm Alumina Ceramics?
Tsis zoo li cov txheej txheem kev txiav, UV laser txiav yog ib qho uas tsis yog - kev sib cuag machining txheej txheem uas tshem tawm cov txiav quab yuam ua ncaj qha rau ntawm ceramic substrate.
Kev ua kom zoo zoo 355 nm UV laser tuaj yeem txo cov thermal puas thaum tswj xyuas qhov tseeb qhov tseeb thiab ntug zoo.
Tej yam zoo muaj xws li:
---- Mechanical stress tsawg
---- Ib cheeb tsam me me thaum tshav kub kub cuam tshuam (HAZ)
---- Txo ntug chipping
---- High-dimensional sib xws
---- Kev ua tau zoo heev rau cov contours complex thiab micro-feature
---- Haum rau nyias ceramic substrates thiab precision electronic ntim
Rau siab -kev ntseeg siab hauv cov ntawv thov hluav taws xob, kev ua kom zoo dua-xws li laser zog, mem tes zaus, scanning lub tswv yim, thiab pab roj tsis muaj zog- yog ib qho tseem ceeb sib npaug li kev ua haujlwm ntawm lub tshuab.
