6061 txhuas alloy yog dav lees paub tias yog ib qho khoom siv ntau yam6000 series wrought aluminiumMuaj ntau tus neeg yuav khoom xav tias qib kev lag luam 6061 tuaj yeem pab tau rau cov xwm txheej tsim khoom semiconductor ncaj qha. Txawm li cas los xij, qhov sib txawv ntawm kev lag luam ib txwm muaj 6061 thiab qib semiconductor 6061 tsis yog qhov teeb meem yooj yim ntawm kev siv tau. Nws yog nyob ntawm qhov kev pheej hmoo ntawm kev ntseeg siab uas txiav txim siab seb cov chaw tsim khoom puas twv yuav siv cov khoom siv hauv cov khoom siv semiconductor precision.

Cov qhov tsis zoo me me hauv cov khoom siv txhuas rau cov khoom siv semiconductor tsis ua rau muaj kev puas tsuaj tam sim ntawd. Thaum raug rau hauv lub tshuab nqus tsev thiab cov pa roj corrosive ntev dhau lub voj voog ua haujlwm ntev, cov qhov tsis zoo me me no maj mam nthuav dav. Cov txiaj ntsig tshwm sim ua qhov tsis sib xws ntawm cov khoom, oxidation tsis zoo thiab thaum kawg corrosion tsis ua haujlwm. Kev tshawb fawb tsis ntev los no lees paub tias qhov sib txawv tseem ceeb tsis yog nyob rau hauv lub npe alloy nws tus kheej. Nws pib los ntawm kev tswj hwm qhov tseeb ntawm microstructure thiab cov txheej txheem tsim khoom, tshwj xeeb tshaj yog qhov loj me thiab kev faib tawm ntawm cov khoom theem ob, uas yog Al₁₅ (Fe, Mn)₃Si₂. Tus cwj pwm no ncaj qha tswj hwm qhov kev ruaj khov corrosion ntawm alloy. Txawm tias nrog qib 6061 zoo sib xws, cov kev hloov pauv hauv kev lag luam thiab cov kev hloov pauv semiconductor feem ntau yog ob lub kaw lus ua haujlwm sib txawv.

Qib semiconductor 6061 raug tsib qhov kev hloov kho tseem ceeb piv rau tus qauv kev lag luam 6061.

Ua ntej tshaj plaws yog kev ua kom huv si, hloov ntawm kev ua raws li cov khoom xyaw yooj yim mus rau kev tswj hwm kev ua qias tuaj. Cov khoom siv semiconductor muaj kev txwv nruj rau cov pa tawm ntawm cov khoom siv, kev ua qias tuaj ntawm ionic thiab kev ua rau xeb. Cov chaw tsim khoom yuav tsum txo qhov kev hloov pauv ntawm Fe, Si thiab Cu. Thaum cov khoom siv ib txwm muaj 6061 tso cai rau cov ntsiab lus tooj liab txij li 0.15% txog 0.4%, cov khoom siv semiconductor-qib kaw cov khoom no hauv ib txoj kab nruj kom txo tau kev pheej hmoo ntawm kev xeb hluav taws xob. Lub hom phiaj tseem ceeb ntawm kev ua kom zoo dua yog kev ua kom huv si thiab kev faib cov khoom me me Al₁₅ (Fe, Mn)₃Si₂ theem ob.

Cov kev soj ntsuam metallographic qhia txog ntau yam morphologies ntawm cov theem intermetallic no. Acicular β-Al₅FeSi ua haujlwm phem tshaj plaws, yooj yim tawg, xeb thiab oxidation tsis zoo. Blocky thawj α-Al(Mn,Fe)Si muab kev pheej hmoo txo ​​qis tab sis tsis ruaj khov. Zoo thiab dispersed α-theem muab kev sib npaug ntawm kev siv tshuab thiab kev ua tau zoo tas li. Qhov zoo tshaj plaws "Suav tus cwj pwm-puab" α-theem nta cov npoo puag ncig tsis muaj cov ces kaum ntse, ua tiav qhov ruaj khov siab tshaj plaws thiab tiv taus corrosion.

Qhov thib ob, kev kho cua sov yog kho kom haum rau koj tus kheej es tsis txhob siv cov zaub mov txawv. Tus qauv T6 temper rau 6061 ib txwm siv cov tshuaj thoob ntiaj teb thiab cov kev laus. Cov khoom siv semiconductor qib xav tau cov sijhawm thermal tshwj xeeb. Nws siv qhov kub ntawm cov tshuaj ntawm 540 ~ 550 ° C, kwv yees li 20 ° C siab dua li T6 ib txwm, los pab txhawb kev yaj tag nrho ntawm Mg₂Si precipitates. Lub sijhawm tuav tau khaws cia rau 2 teev, ua ke nrog staged lossis high-speed quenching los txhim kho kev ua haujlwm tseem ceeb ntawm cov phaj tuab. Cov txheej txheem laus tau kho rau 170 ° C rau 12 teev, sib npaug lub zog kho tshuab thiab cov khoom anodizing.

Qhov thib peb, kev txo kev ntxhov siab sab hauv dhau los ua ib qho txheej txheem yuav tsum tau ua es tsis yog ib kauj ruam xaiv tau. Tus qauv T6 txhuas khaws cov kev ntxhov siab sab hauv uas tseem tshuav, uas ua rau muaj kev hloov pauv zuj zusthaum lub sijhawm ua haujlwm CNC precision. Semiconductor-qib 6061 ua kom muaj zog T651 temper. Cov khoom siv dhau los ntawm 1% txog 3% kev ncab mus tas li ua ntej kev laus dag kom tshem tawm ntau dua 90% ntawm kev ntxhov siab seem. Kev ncab ntxiv lossis kev nias ncaj yog siv rau cov phaj tuab, kom ntseeg tau tias qhov siab tshaj plaws ≤0.02 hli rau cov khoom loj-loj.

Qhov thib plaub, cov qauv me me raug tswj hwm kom zoo rau qhov zoo sib xws. Cov khoom me me thib ob loj ua haujlwm ua qhov chaw pib rau xeb thiab qhov tsis zoo rau cov yeeb yaj kiab anodized. Kev taw qhia ntawm α-Al₁₅ (Mn, Fe)₃Si₂ cov noob yuav tsum tau tswj hwm kom zoo. Cov noob ntsug tsim cov qhov ntev thaum lub sijhawm anodization, ua rau cov xov xwm corrosive nkag mus rau hauv cov txhuas substrate thiab ua rau tsis zoo rau kev tiv thaiv corrosion. Cov noob recrystallized kuj raug saib xyuas kom nruj kom tsis txhob muaj cov noob coarsening thiab anodizing speckle defects.

Qhov thib tsib, kev ua tau zoo ntawm anodizing yuav tsum ntsuas tau thiab txheeb xyuas tau. Cov txheej txheem anodized nyuaj ntawm semiconductor txhuas yuav tsum ua tau raws li cov qauv lees txais nruj. Nws yuav tsum tiv taus tsawg kawg 4 teev ntawm kev raug rau 5% hydrochloric acid, ntau dua li 2 ~ 3 teev kev ua haujlwm ntawm cov qauv T6 6061. Lub zog tawg mus txog ≥640 V.DC / mil, thiab qhov microhardness ntawm cov txheej oxide tshaj 400 HV0.1. Cov qauv txheej txheem muaj cov qhov me me ntsug ntev thiab cov txheej txheem thaiv ntom ntom.

Daim ntawv qhia kev siv tshuab tag nrho rau semiconductor-qib 6061 ua raws li cov txheej txheem meej: kev tswj cov khoom muaj purity siab, kev kho cua sov raws li qhov xav tau ntawm 540 ~ 550 ° C kua ntxiv rau 170 ° C laus, kev txo kev ntxhov siab T651 yuav tsum tau ua, cov qauv microstructure zoo thiab sib npaug, thiab kev ua tau zoo anodizing nrog cov ntsuas corrosion thiab dielectric tsim nyog.

Cov chaw tsim khoom hauv tsev tam sim no tau ua tiav lub peev xwm tsim khoom loj rau semiconductor qib 6061 txhuas phaj. Cov khoom siv txhuas zoo rau cov khoom siv semiconductor tab tom rhuav tshem kev cia siab rau kev xa khoom mus ntev los ntawm kev tsim kho hauv zos. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev hloov kho 6061 ib txwm mus rau hauv cov khoom siv semiconductor tsim nyog tsis yog tsuas yog hloov pauv lossis ntxiv ib kauj ruam ua tiav. Nws xav tau kev ua kom zoo tag nrho uas suav nrog kev tsim tshuaj lom neeg, kev ua haujlwm thermal, kev tswj kev ntxhov siab, kev tswj hwm microstructure thiab kev lees paub anodizing. Yog tsis muaj daim ntawv pov thawj tshuaj xyuas los txhawb cov ntsuas kev ua tau zoo, hu ua "semiconductor qib" txhuas tsuas yog rov ntim khoom lag luam qib kev lag luam.

Peb lub tuam txhab muab cov khoom siv semiconductor qib tsim nyog6061 txhuas phaj nrog rauCov phaj txhuas 6061 rau kev lag luam ib txwm muaj, txhawb kev txiav kom raug thiab kev ua CNC machining. Yog tias koj tab tom nrhiav cov khoom siv txhuas ruaj khov, taug qab tau rau cov khoom siv semiconductor, cov khoom siv nqus tsev thiab cov khoom siv ua haujlwm raug, peb tuaj yeem muab cov ntawv qhia txog kev kuaj xyuas cov khoom siv kom phim koj cov lus qhia nruj ntawm kev tsim khoom.
