Precision qhov chaw ua muaj ntau yam zoo. Ua ntej ntawd, peb kuj tau koom nrog koj qhov tshwj xeeb ntawm cov kev ua tiav kev ua tiav. Qhov tseem ceeb tshaj plaws yog tias nws muaj peev xwm ncav cuag lub siab tshaj plaws uas qhov kev sib tw ua tsis tau zoo, thiab kev siab tshaj kuj yog nyob ntawm cov cuab yeej ua hauj lwm thiab qhov tseeb Qhov kev tiv thaiv kab mob, thiab kev siv lub ntsej muag yog siv raws li cov kev nplua nuj ntawm cov nyiaj ntawm cov khoom muab tshem tawm lossis ntxiv rau sab nraud. Dab tsi yog cov yam ntxwv ntawm qhov kev txiav txim siab qhov ua?
Ua ntej, kev txiav qhov ntaiv
Muaj kev ncaj ncees tig, daim iav sib tsoo thiab kev sib tsoo. Kev nplua lathes yog machined rau precision lathes siv micro-ua ib leeg-Crystal pob zeb diamond raws cov cuab yeej. Lub pluaj txiav tsuas yog li 1 micron. Nws yog siv los tshuab cov khoom siv fais fab tsis yog hlau, xws li kheej kheej, pleev xim, thiab lub dav hlau dav hlau nrog high precision thiab tsos. . Piv txwv li, ib daim iav ntawm daim iav nrog ib txoj kab uas siv li ntawm 800 mm yog siv rau cov khoom siv fusion nuclear. Qhov siab tshaj plaws yog 0,1 μm thiab qhov pom kev roughness yog Rz 0.05 μm.
Thib ob, kev txiav txim siab qhov ua
Thaum kev txiav txim siab ntawm qhov kev txiav txim siab yog qhov tseeb ntawm cov nanometers los yog thaum kawg ntawm cov chaw atomic (atomic lattice mus kev ntawm 0.1 mus rau 0.2 nanometers), ultra-precision machining ntawm qhov yuav tsis raug yoog, thiab tshwj xeeb high-precision machining ntawm qhov chaw yog tsim nyog, xws li, kev siv cov tshuaj chemical. Kev siv hluav taws xob, thermal lub zog, lossis hluav taws xob, thiab lwm yam cuab yeej ua kom muaj zog tshaj li qhov sib koom tes ntawm cov atoms, yog li tshem qhov txuas, kev sib txuas, los yog khoob khoob ntawm qhov chaw ntawm cov khoom ua haujlwm sab nraud kom ua tiav lub hom phiaj ntawm kev txiav txim siab ultra . Cov kev xyum zoo li no yog tshuaj pleev tshuab, ion sputtering thiab ion implantation, electron beam raug, lem beam ua, hlau evaporation, thiab molecular beam epitaxy.
Cov yam ntxwv ntawm qhov kev txiav txim siab qhov ua tau ua tiav rau hnub no. Yog xav paub ntxiv, thov mus saib peb qhov xov xwm. Peb lub tuam txhab yog tshwj xeeb ntawm kev tsim khoom ntawm cov qauv tsis-txheem hlau. , Titanium, aluminium thiab lwm yam kev sib tsoo hlau tau tsim rau ntau xyoo ntawm kev nag lossis daus
