Kev Tswj Xyuas Cov Txheej Txheem PVD Deposition: Cov Kauj Ruam Tseem Ceeb Rau Cov Txiaj Ntsig Zoo Tshaj Plaws

Kev Taw Qhia:

Txais tos rov qab rau peb cov blog series ntawm PVD (Physical Vapor Deposition) txheej txheem! Hauv tsab xov xwm no, peb yuav kawm tob txog cov kauj ruam yooj yim uas yuav tsum tau ua kom tau txais txiaj ntsig zoo nrog PVD deposition. Los ntawm kev paub txog cov txheej txheem PVD deposition, koj tuaj yeem txhim kho qhov ruaj khov, tiv taus corrosion thiab zoo nkauj ntawm koj cov khoom. Thov koom nrog peb thaum peb tshawb nrhiav cov yam tseem ceeb uas ua rau muaj kev vam meej ntawm PVD txheej txheem.

Kev Nkag Siab Txog Kev Tso Tawm PVD:
PVD deposition yog ib txoj kev siv dav dav rau kev siv cov zaj duab xis nyias thiab cov txheej txheej rau ntau qhov chaw xws li hlau, ceramics thiab yas. Cov txheej txheem no cuam tshuam nrog kev ua kom cov khoom khov kho ua pa thiab ua rau cov dej noo rau ntawm lub substrate, tsim cov zaj duab xis nyias. Cov txheej txheem txheej txheem feem ntau muaj cov yam ntxwv zoo dua xws li qhov nyuaj, tiv taus kev sib txhuam thiab zoo li ci ntsa iab.

Cov kauj ruam tseem ceeb rau kev ua kom zoo dua PVD deposition:
1. Kev npaj nto: Kev npaj nto yog qhov tseem ceeb ua ntej pib cov txheej txheem PVD deposition. Kev ntxuav, polishing thiab tshem cov roj ntawm lub substrate kom huv si yuav tshem tawm cov khoom tsis huv, xyuas kom muaj kev sib txuas zoo thiab tiv thaiv cov qhov tsis zoo. Ib qho chaw huv si pab txhawb kev sib txuas zoo dua thiab txhim kho qhov zoo ntawm cov deposit.

2. Chav Tso Khoom: Ib puag ncig huv si thiab tswj tau yog qhov tseem ceeb rau kev ua tiav PVD deposition. Lub chav tso khoom raug tswj hwm ntawm qhov siab qis thiab tswj tau qhov kub, uas tso cai rau cov atoms lossis molecules uas tau ua pa kom txav mus los tau yam tsis muaj kev cuam tshuam. Kev xaiv cov kev ntsuas tso khoom xws li qhov siab, qhov kub thiab lub sijhawm tso khoom kom raug ua kom ntseeg tau tias cov zaj duab xis tuab thiab sib xws kom tau txiaj ntsig zoo tshaj plaws.

3. Kev xaiv qhov chaw evaporation: Kev xaiv qhov chaw evaporation cuam tshuam loj heev rau cov txheej txheem PVD deposition. Cov khoom siv xaiv yuav tsum yog cov khoom huv si kom ntseeg tau tias cov yeeb yaj kiab zoo. Cov chaw evaporation nrov suav nrog cov nkoj uas tiv taus cua sov, cov chaw electron beam, lossis magnetron sputtering cathodes, txhua tus tsim los ua kom tau raws li cov kev xav tau tshwj xeeb.

4. Kev saib xyuas zaj duab xis thiab kev tswj qhov tuab: Kev saib xyuas tiag tiag thiab kev tswj qhov tuab ntawm zaj duab xis yog qhov tseem ceeb rau kev tso PVD kom sib xws thiab raug. Cov thev naus laus zis niaj hnub xws li quartz crystal microbalances thiab optical monitoring systems tso cai rau kev tswj hwm thiab kev hloov kho zoo dua thaum lub sijhawm tso. Kev tswj kom qhov tuab ntawm zaj duab xis txaus ua kom muaj kev ua tau zoo thiab kev ua haujlwm zoo.

5. Kev kho tom qab tso cov zaj duab xis: Tom qab PVD tso cov zaj duab xis tiav lawm, cov kauj ruam tom qab kho tuaj yeem txhim kho cov yam ntxwv ntawm zaj duab xis. Kev ua kom sov, kev siv ion bombardment, lossis ion etching yog cov txheej txheem siv dav dav los ua kom zoo dua qhov kev sib txuas, qhov tiav ntawm qhov chaw, thiab kev so ntawm cov zaj duab xis tso. Kev kho tom qab kom zoo ua kom ntseeg tau tias cov txheej PVD coatings kav ntev thiab ua tau zoo.
