Mastering the PVD Deposition Process: Cov kauj ruam tseem ceeb rau cov txiaj ntsig zoo

Taw qhia:

Txais tos rov qab rau peb cov blog series ntawm PVD (Lub Cev Vapor Deposition) txheej txheem! Hauv tsab xov xwm no, peb yuav ua qhov tob tob rau hauv 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 cov kav ntev, corrosion kuj thiab zoo nkauj ntawm koj cov khoom. Thov koom nrog peb thaum peb tshawb nrhiav cov ntsiab lus tseem ceeb uas ua rau muaj kev vam meej PVD txheej txheej.

Nkag siab txog PVD Deposition:
PVD deposition yog ib txoj kev siv dav rau kev siv cov yeeb yaj kiab nyias thiab cov txheej txheem ntawm ntau qhov chaw xws li hlau, ceramics thiab yas. Cov txheej txheem cuam tshuam nrog cov evaporation ntawm cov khoom siv tom qab los ntawm condensation mus rau lub substrate, tsim ib zaj duab xis nyias. Cov txheej txheej tshwm sim feem ntau nthuav tawm cov khoom muaj zog xws li hardness, abrasion tsis kam thiab glossy tsos.

Cov kauj ruam tseem ceeb rau optimizing PVD deposition:
1. Kev npaj deg: Kev npaj saum npoo yog qhov tseem ceeb ua ntej pib txheej txheem PVD deposition. Kev tu kom huv, polishing thiab degreasing ntawm lub substrate yuav tshem tawm impurities, xyuas kom meej adhesion thiab tiv thaiv tsis xws luag. Ib tug pristine nto txhawb zoo txheej adhesion thiab txhim kho tag nrho cov zoo ntawm deposit.

2. Deposition Chamber: Ib puag ncig huv thiab tswj tau yog qhov tseem ceeb rau kev ua tiav PVD deposition. Lub deposition chamber yog khaws cia nyob rau hauv qis siab thiab tswj qhov kub thiab txias, cia lub vaporized atoms los yog molecules txav mus dawb yam tsis muaj kev cuam tshuam. Kev xaiv kom raug ntawm qhov kev tso nyiaj tsis zoo xws li lub siab, qhov kub thiab txias thiab lub sijhawm tso tawm kom ntseeg tau tias cov yeeb yaj kiab tuab thiab qhov sib xws rau kev pom zoo.

3. Kev xaiv ntawm evaporation qhov chaw: xaiv qhov evaporation zoo heev cuam tshuam rau PVD deposition txheej txheem. Cov khoom xaiv yuav tsum yog siab purity los xyuas kom meej cov yeeb yaj kiab zoo. Nrov evaporation qhov chaw muaj xws li cov nkoj uas muaj cua sov, cov khoom siv hluav taws xob, lossis magnetron sputtering cathodes, txhua tus tsim kom tau raws li cov kev cai tshwj xeeb.

4. Kev saib xyuas cov yeeb yaj kiab thiab cov tuab tuab: kev saib xyuas lub sijhawm tiag tiag thiab kev tswj xyuas meej ntawm cov yeeb yaj kiab tuab yog qhov tseem ceeb rau kev ua kom zoo thiab raug PVD deposition. Cov thev naus laus zis niaj hnub xws li quartz siv lead ua microbalances thiab kho qhov muag saib xyuas lub tshuab tso cai rau kev txhim kho kev tswj hwm thiab kev hloov kho thaum lub sij hawm tso nyiaj. Kev tuav cov yeeb yaj kiab kom txaus kom ntseeg tau tias qhov kev xav tau thiab kev ua haujlwm.

5. Kev kho tom qab tso tawm: Tom qab PVD deposition tiav lawm, cov kauj ruam tom qab kho tuaj yeem txhim kho cov khoom ntawm cov yeeb yaj kiab ntxiv. Annealing, ion bombardment, los yog ion etching yog dav siv cov tswv yim los ua kom zoo adhesion, nto tiav, thiab kev ntxhov siab ntawm cov yeeb yaj kiab tso. Kev kho kom zoo tom qab ua kom lub neej ntev thiab kev ua haujlwm ntawm PVD txheej.
