Hauv cov txheej txheem tsim khoom niaj hnub no, cov khoom lag luam precision, cov cuab yeej siv tau zoo, thiab cov khoom siv lub neej ua haujlwm nce ntxiv nyob ntawm kev nce qib hauv engineering nto. Raws li cov txheej txheem tseem ceeb ntawm kev kho saum npoo, cov txheej txheem txheej txheej nyuaj tau siv dav hauv kev lag luam xws li cov cuab yeej txiav, pwm, cov khoom tseem ceeb hauv tsheb, thiab 3C cov khoom. Nws yog ib qho tseem ceeb rau kev txhim kho durability, kev cia siab, thiab kev ua tau zoo tag nrho.
No.1 Technical Definitioning thiab Functional Positioning
"Hard coatings" feem ntau yog hais txog kev ua haujlwm nyias cov yeeb yaj kiab tso rau ntawm lub substrate ntawm lub cev Vapor Deposition (PVD) lossis Tshuaj Vapor Deposition (CVD) txoj kev. Cov txheej txheej no feem ntau muaj qhov tuab ntawm 1 txog 5 μm, nrog microhardness siab (> 2000 HV), qis coefficient ntawm kev sib txhuam (<0.3), zoo thermal stability, thiab muaj zog interfacial adhesion - qhov tseem ceeb txuas ntxiv lub neej kev pab cuam thiab kev txwv ntawm cov ntaub ntawv substrate.
Tsis yog tsuas yog ua raws li qhov "npog", cov txheej tawv tawv yog tsim los ntawm cov txheej txheem ua kom zoo, cov ntaub ntawv xaiv, thiab cov txheej txheem txheej txheej txheej txheej adhesion. Qhov no ua rau cov txheej txheem tiv thaiv kev ua haujlwm nyuaj thaum tib lub sijhawm xa cov hnav tsis kam, thermal stability, thiab tiv thaiv corrosion.
No.2 Cov Ntsiab Cai Ua Haujlwm ntawm Cov Txheej Txheem Hard
Cov txheej txheem nyuaj yog feem ntau tso nrog ob txoj kev tseem ceeb: Lub cev Vapor Deposition (PVD) thiab Tshuaj Vapor Deposition (CVD).
1. Lub cev Vapor Deposition (PVD)
PVD yog txheej txheem nqus tsev vacuum uas txheej txheej yog evaporation, sputtering, los yog ionization thiab tso ib zaj duab xis nyias rau ntawm qhov chaw substrate. Cov txheej txheem feem ntau muaj xws li:
Cov khoom evaporation los yog sputtering
Vapor-phase thauj: Atoms / ions migrate nyob rau hauv ib qho chaw nqus tsev vacuum
Kev tsim cov yeeb yaj kiab: Condensation thiab kev loj hlob ntawm cov txheej tuab ntawm cov substrate
Cov txheej txheem PVD feem ntau suav nrog:
Thermal Evaporation
Magnetron Sputtering
Arc Ion Txheej
2. Chemical Vapor Deposition (CVD)
CVD suav nrog kev qhia cov pa roj carbon monoxide ua ntej ntawm qhov kub siab kom muaj tshuaj lom neeg ntawm cov substrate nto, tsim cov txheej txheej. Txoj kev no tsim nyog rau cov txheej txheem thermally ruaj khov xws li TiC, TiN, thiab SiC.
Cov yam ntxwv tseem ceeb:
Muaj zog adhesion rau substrate
Muaj peev xwm tsim cov txheej tuab tuab
Kev ua haujlwm siab kub yuav tsum tau thermally resistant substrates
No.3 Application Scenarios
Hauv kev lag luam ib puag ncig uas muaj kev thauj khoom siab thiab kev ua haujlwm siab, cov khoom yuav raug kev sib txhuam, corrosion, thiab thermal shock. Hard coatings tsim ib tug high-hardness, tsis muaj kev sib txhuam, thiab thermally ruaj khov txheej tiv thaiv uas ho txhim khu ib feem kev ua tau zoo thiab lifespan:
Cov cuab yeej txiav: Txheej xws li TiAlN thiab AlCrN zoo heev txhim kho thermal kuj thiab hnav kev ua haujlwm, txuas lub neej ntawm 2 mus rau 5 zaug, txo cov cuab yeej hloov pauv, thiab txhim kho kev ua haujlwm zoo ib yam.
Pwm thiab Punches: TiCrAlN thiab AlCrN coatings txo hnav, galling, thiab thermal qaug zog tawg-txhim kho pwm kev pab cuam lub neej, ib feem zoo, thiab txo downtime.
Automotive Cheebtsam: DLC (Diamond-Like Carbon) coatings ntawm cov khoom xws li tappets, piston pins, thiab valve lifters txo kev sib txhuam thiab hnav tus nqi, ncua sij hawm hloov, thiab txhim kho roj efficiency.
3C Consumer Electronics: TiN, CrN, thiab lwm yam zoo nkauj txheej txheej ntawm lub xov tooj smartphones thiab lub koob yees duab bezels muab kev tiv thaiv khawb thiab tiv thaiv corrosion thaum khaws cov hlau ua tiav rau kev txhim kho cov neeg siv khoom.
