1｜ Kev Sib Tham ntawm Alumina thiab Nws Daim Ntawv Thov Alumina ceramics, vim lawv cov rwb thaiv tsev, siab -kub tsis kam, hnav tsis kam, corrosion resistance, thiab siab tshuaj stability, yog dav siv nyob rau hauv teb xws li semiconductors, tshiab zog, thiab high{2}}kawg electronics. Tshwj xeeb, alumina ceramics tuaj yeem hloov tau zoo rau qhov chaw huab cua xws li lub tshuab nqus tsev thiab qhov kub siab, ua rau lawv tsim nyog raws li cov khoom siv raw rau cov txheej txheem hauv cov khoom siv semiconductor. Muaj cov ntaub ntawv zoo ib leeg yog deb ntawm qhov txaus; cov ntaub ntawv no tseem xav tau cov txheej txheem ua haujlwm zoo nyob rau hauv siab - cov khoom siv kawg lossis cov txheej txheem kom paub meej lawv cov khoom thiab ua tiav kev ua tiav ntau dua hauv kev tsim khoom. Piv txwv li, cov roj nozzles siv hauv cov khoom siv semiconductor xav tau kev tiv thaiv corrosion, feem ntau ua tiav nrog cov khoom siv alumina ceramic. Txhawm rau tso cai rau lub nozzle kom ua tiav kev tswj hwm kev ua tau zoo, qhov tseeb micro- qhov txheej txheem thev naus laus zis yuav tsum tsim kom muaj cov qauv micro- qhov zoo, ua kom muaj kev tswj xyuas cov roj / kua dej nrawm thiab ntim. Yog li ntawd, kev sib raug zoo ntawm alumina thiab cov txheej txheem ua haujlwm zoo yog kev sib koom ua ke.
2｜ Sib tham txog Kev Ua Haujlwm ntawm Alumina Micropores Ceramic ua ib txwm yog qhov nyuaj. Ua ntej, nws yog cov khoom siv tawv thiab nkig; siv cov txheej txheem kev kho tshuab ib txwm siv tau yooj yim ua rau micro- tawg thiab chipping, ua rau cov txiaj ntsig nyuaj los xyuas kom meej. Qhov thib ob, nws yog cov khoom siv insulating thiab tsis yog -conductive, yog li siab -precision hluav taws xob paug machining siv tsis tau. Ua ntej qhov tshwm sim ntawm femtosecond lasers, ua tiav siab -precision, siab - ua haujlwm zoo ntawm alumina ceramic micropores yog ib txoj haujlwm nyuaj. Hais tias, yuav ua li cas siab precision thiab siab zoo raug soj ntsuam? Hauv lwm lo lus, peb yuav ntsuas seb qhov ntsuas ntawm micropore ua tau zoo lossis phem? Kuv ntseeg tias muaj ob yam: micropore loj thiab micropore morphology.
1. Micropore loj muaj xws li: lub qhov taub thiab nws qhov tseeb, roundness, taper, thiab lwm yam. Peb qhov ntsuas no feem ntau cuam tshuam txog peb - qhov loj me ntawm micropore, thaum qhov tseeb yog qhov sib txawv ntawm qhov zoo tagnrho tus nqi thiab tus nqi tiag tiag los ntawm kev siv tshuab.
2. Micropore morphology muaj xws li: nto morphology thiab sidewall morphology. Ob qhov ntsuas no feem ntau tshuaj xyuas seb lub qhov nkag thiab sab hauv phab ntsa puas muaj qhov rov ua dua - txheej txheej, chipping, splashes, tawg, los yog nto smoothness. Cov ntsuas no cuam tshuam rau kev nkag mus ntawm lub teeb kab teeb, gases, thiab kua thiab tseem cuam tshuam rau cov khoom lag luam kev ntseeg siab thiab kev pabcuam lub neej.
3｜ Sib tham txog Femtosecond Laser Ua ntawm Alumina Femtosecond laser, raws li kev txiav -ntug microhole ua tshuab, qhia tau hais tias muaj txiaj ntsig zoo hauv kev ua cov alumina. Nrog nws cov ultra- luv mem tes dav thiab lub zog siab kawg nkaus, nws tuaj yeem ua rau cov khoom siv tsis tau dhau los ntawm lub xeev molten. Ua ke nrog nws cov micrometer- nplai zoo engraving, cov microholes yog qhov tseeb heev nrog zoo heev roundness. Tsis tas li ntawd, kev ua haujlwm txias ntawm femtosecond lasers tiv thaiv kev tsim cov txheej txheem rov ua dua, microcracks ntawm qhov chaw lossis cov phab ntsa sab hauv ntawm alumina, thiab tsis ua rau yellowing lossis blackening ntawm cov khoom. Hauv lwm lo lus, tsis hais txog txoj kev ua haujlwm lossis qhov sib piv ntawm alumina ceramics, femtosecond lasers tuaj yeem ua tiav ultra-siab precision, siab - zoo microhole ua. Tam sim no, femtosecond lasers tuaj yeem ua tiav microhole ua nrog qhov tsawg kawg nkaus txoj kab uas hla ntawm 0.02mm (thickness 0.2mm) thiab qhov tseeb hauv ± 1μm. Koj puas paub txog lwm yam thev naus laus zis uas tuaj yeem ua tiav cov txheej txheem microhole?
