Ion Plating
Jun 14, 2018| Ntsiab Cai ntawm Ion Plating
Ion plating yog hais txog kev siv roj tawm mus rau cov pa roj carbon dioxide los yog cov khoom vaporized nyob hauv lub tshuab nqus tsev. Evaporation cov ntaub ntawv los yog lawv reactants tso rau ntawm lub chaw ua hauj lwm nyob rau hauv qhov kev txiav txim ntawm ion bombardment ntawm roj ions los yog vaporized cov ntaub ntawv. Ion plating tau faib ua magnetron ntsev ntawm ion plating, reactive ion plating, hollow cathode discharge ion plating (hollow cathode evaporation), ntau arc ion plating (cathode arc ion plating) thiab hais txog. Ion plating combines glow discharge, ntshav technology thiab tshuab nqus tsev qhuav, uas tsis tsuas yog txhim kho qhov kev ua tau zoo ntawm cov txheej, tab sis kuj zoo heev nthuav cov ntaub ntawv ntawm txheej txheej. Ntxiv rau qhov zoo ntawm lub tshuab nqus tsev nqus dej, nws kuj muaj qhov zoo ntawm cov yeeb yaj kiab zaj duab xis, zoo diffraction, ntau cov khoom uas tau plated thiab li ntawm. Lub hauv paus ntsiab lus ntawm ion plating yog ionize lub vapor ntawm ib lub hlau los yog hlau los ntawm txoj kev xuab zeb los yog tawm ntawm cov pa roj. Ion plating muaj cov cua kub, kev sib evaporation, thiab cov txheej txheem cov txheej txheem (xws li TiN thiab TiC). Cov khoom evaporated txheej atoms ua rau me me ntawm ionization thaum dhau los ntawm cheeb tsam lub ntsej muag, thiab ya mus rau lub chaw ua hauj lwm hauv kev ua haujlwm ntawm ib cheeb tsam hluav taws xob, nws tawm tsam ntawm cov hauj lwm nrog lub zog ntawm ob peb txhiab electron volts, thiab yuav raug muab tso rau hauv lub substrate mus rau ib tug tob ntawm txog ob peb nanometers. Yog li ntawd, qhov kev tiv thaiv txog kev tsim ntawm cov txheej yog zoo heev tuaj, thiab cov khoom siv ntim cov khoom tsis muaj nuj nqi uas tsis muaj kev pov tseg hauv cov khoom siv hauv tsev. Kev tua ntawm cov pa ions thiab cov khoom siv xuab zeb ntawm qhov chaw ua haujlwm yuav tshem tawm cov paug tuaj yeem txhim kho lub zog ntawm tsev neeg.
Qhov Zoo Ntawm Ion Plating
1. Muaj peev xwm ua kom muaj zog txawv
Nyob rau hauv txoj kev ion plating txheej txheem, cov khoom ntawm cov khoom evaporating txav mus rau hauv cov kev taw qhia ntawm lub hwj huam kab hauv daim ntawv ntawm them ions nyob rau hauv lub teb hluav taws xob. Yog li, txhua feem ntawm qhov chaw muaj hluav taws xob tuaj yeem tau txais ib txheej zoo plating, uas yog siab tshaj qhov qub nqus hlau lo hauv qhov muab cov plating hauv qhov ncaj qha. Yog li ntawd, qhov no yog heev haum rau lub txheej on puab qhov, qhov zawj thiab qhov nqaim qhov nyob rau hauv plated qhov chaw. Kev nqus plua plav feem ntau tuaj yeem ua rau lub qhov ncaj ncaj tau co. Evaporation feem tsuas tuaj yeem txav tau li nce ntaiv. Tab sis ion plating yuav npaaj lub tsho thiab sab hauv qhov ntawm qhov chaw. Cov neeg raug nplua yuav tau ya mus raws li cov kev qhia nyob rau hauv txhua qhov chaw hauv lawv lub vojvoog xws li zaum ntawm lub hoom qav taub.
2. Cov txheej txheem zoo zoo
Cov xuab zeb uas muaj plhis yog khaus, pinhole dawb, npuas pub dawb, thiab tsis hnav cov hnyav. Txawm tias cov khib nyiab thiab grooves tuaj yeem plated tusyees tsis muaj metallurgy. Cov khoom xws li threads kuj tau plated. Hom no kuj tuaj yeem kho kho xws li cov feeb tawg thiab cov pits ntawm cov khoom ntws, uas zoo tuaj yeem txhim kho qhov zoo ntawm lub cev thiab lub cev thiab cov cuab yeej ntawm cov khoom plated. Kev qaug zog kuaj pom tias yog ua haujlwm zoo, txoj hauv kev ua haujlwm ntawm qis qis yuav yog 20% ~ 30% siab tshaj ua ntej plating.
3. Txoj phuam ntxuav hniav dawb yog yooj yim
Feem ntau ntawm cov txheej txheem uas twb muaj lawm yuav tsum tau nruj tu ntawm cov khoom ua haujlwm ua ntej, uas yog cov nyom thiab kim. Txawm li cas los xij, txoj kev txhim kho ion plating nws tus kheej muaj ib qho kev txhim kho kev txhim kho kev sib raug zoo, thiab cov nyhuv no tseem thoob plaws txheej txheem txheej txheem. Cov kev ua kom huv zoo yog zoo heev, thiab cov plating tuaj yeem coj ncaj nraim tuaj rau hauv lub substrate, uas ua rau cov kab xo zoo thiab ua kom yooj yim ua kom zoo dua qub.
4. Ntau yam khoom siv tau plated
Ion plating txoj kev siv high-energy ions rau bombard lub workpiece nto, yog li hais tias ib tug loj npaum li hluav taws xob lub zog yog hloov mus rau hauv lub zog hluav taws xob nyob rau saum npoo ntawm lub workpiece, li no txhawb cov kev loj hlob tshuaj lom neeg ntawm cov tawv nqaij. Txawm li cas los, tag nrho workpiece, tshwj xeeb tshaj yog cov tub ntxhais ntawm lub workpiece tsis cuam tshuam los ntawm high kub. Yog li, qhov txheej txheem txheej no muaj ntau hom kev siv ntau dua thiab nws tsawg dua. Feem ntau, ntau yam hlau, cov hlau ntoo, thiab tej yam khoom siv hluavtaws, cov khoom siv tha xim, cov khoom siv kub tha xim, thiab cov khoom siv kub ntxhov. Nws tuaj yeem phaj cov hlau tsis yog hlau los sis hlau ntawm cov hlau ua haujlwm, lossis hlau lossis tsis muaj hlau ntawm cov khoom ua haujlwm tsis-hlau, thiab txawm rau yas, rubber, quartz, ceramics, thiab lwm yam.
