Kawm ntawm Adhesion ntawm pob zeb diamonds (DLC) Films Deposited Los ntawm Mem tes Ion Plating Tshuab - Ntsiab Lus Thiab Txoj Kev Kws Tshaj Lij

Pob zeb diam-zoo li cov duab films (DLC films), raws li cov cim tshiab ntawm cov khoom siv kho qhov muag nyias, muaj kev kho qhov muag, cov khoom hluav taws xob, hluav taws xob, thermal thiab acoustic. Nrog rau qhov zoo ntawm cov cheeb tsam sab nrauv tawg paj, kev kub siab, kev thermal conductivity, kev sib zog ua hauj lwm, ruaj khov khoom, kev poob siab ua hauj lwm thiab ua rau. Nws muaj qhov zoo ntawm daim ntawv thov.

DLC zaj duab xis yog tso los ntawm pulsed arc ion plating, uas yog lub cev ntim cov txheej txheem ntawm lub cev. Cov txheej txheem plating yog yooj yim. Nws tsis tas yuav ntxiv qhov tsis zoo rau lub substrate thiab sau cov roj hauv lub qhov nqus tsev thaum lub txheej txheem plating. Cov txheej txheem plating muaj zoo repeatability thiab yog tsim rau loj batch industrial ntau lawm. DLC zaj duab xis txheej coated los ntawm no txoj kev muaj purity siab, zoo optical transparency; ruaj khov thiab cov khoom ua haujlwm zoo. Nws tuaj yeem raug siv los ua ib qho zoo nkauj duab thaij duab thiab cov yeeb yaj kiab.

Lub pob zeb diamond zoo li cov yeeb yaj kiab tau raug los ntawm lub tshuab nqus tsev twj ntawm lub teb chaws. Qhov cuab yeej no muaj peb qhov chaw ion: qhov roj ion qhov chaw siv los ntxuav thiab kub ntawm lub npoo ntawm cov substrate; ib lub cathode multi-arc ion nruam nrog cov sib nqus pom, nrog ib lub Ti cathode hlau rau lub plating ntawm cov txheej txheem hloov theem nrab; peb qhov chaw ion thib peb yog ib qho teeb meem ntawm qhov teeb meem uas muaj graphite cathode thiab ib qho kev sib. Nws yog siv rau plating diamonds zoo li cov yeeb yaj kiab.

Lub hauv paus thiab txoj kev sim

Qhov khauj khaus ua rau lub plawv dhia muaj qhov cathode, anode, thiab ib qho arcing electrode. Lub cathode yog los ntawm cov khoom siv evaporated thiab qhov chaw ion muaj ib qho kev qhia tshwj xeeb uas tau tsim anode. Nqus plua plav tawm hauv tsev tawm los ntawm qhov cathode ntawm qhov chaw ion ua rau cov khoom siv cathode ua kom qhuav thiab ionize, tsim ib cov ntshav, ntawm ib sab tes, cov ntaub ntawv ib txheej rau ntawm cov substrate, thiab ntawm qhov tod tes, txhawb nqa ib qho tawm hauv tsev. Lub tshuab hluav taws xob emission mechanism ntawm cov kab mob cathode arc discharge yog tsuas yog lub teb electron emission, thiab cov paib emission xav tsim kom muaj ib lub zog ntawm hluav taws xob nyob ntawm cathode nto. Yog li, tsuas yog qhov txawv ntawm qhov cathode thiab anode ntawm ion qhov twg tsis txaus, yog li nws yog tsim nyog los thos tus arc. Tus ntaus ntawv siv ib qho arcing electrode, uas ua kom muaj me me tawm tam sim no thiab ua ntej qhov kev sib thooj ntawm qhov arcing electrodes, thiab tom qab ntawd siv qhov tsis tshua muaj siab ntawm ob lub ntsiab electrode ntawm cathode thiab anode (feem ntau ntawm 40V thiab 400V). Cov roj thiab cov evaporation zom zom mus ua ib qho arc.

Thaum lub sijhawm ua haujlwm, lub tshuab nqus tsev vacuum evacuated rau 2x10 ^-3 Pa, thiab cov Capacitors C ₁ thiab C ₂ raug them, muab lub SCR ib qhov teeb meem arcing. Ib qho me me tawm tam sim no yog tsim los ntawm cov arcing electrodes. Muaj ib qho txheej txheem ntawm lub anode thiab cathode. Lub capacitor C ₁ tso tawm ntawm lub cathode thiab anode. Nrog rau kev tso tawm ntawm capacitor C ₁ zog cia, thaum lub zog muab los ntawm lub capacitor tsis txaus kom muaj kev tawm, qhov paug yuav nres.
