Hauv cov txheej txheem tsim khoom niaj hnub no, qhov tseeb ntawm cov khoom, kev ua haujlwm ntawm cov khoom siv, thiab lub neej ua haujlwm ntawm cov khoom siv yog nyob ntawm kev nce qib hauv kev tsim kho qhov chaw. Raws li txoj kev tseem ceeb ntawm kev kho qhov chaw, cov txheej txheem txheej tawv tau siv dav hauv kev lag luam xws li cov cuab yeej txiav, pwm, cov khoom tseem ceeb hauv tsheb, thiab cov khoom 3C. Nws ua haujlwm ua tus pab cuam tseem ceeb rau kev txhim kho kev ruaj khov, kev ntseeg siab, thiab kev ua tau zoo tag nrho.
No.1 Kev Txhais Lus Txog Kev Siv Tshuab thiab Kev Tso Chaw Ua Haujlwm
"Cov txheej tawv" feem ntau yog hais txog cov zaj duab xis nyias ua haujlwm uas tau muab tso rau ntawm lub substrate los ntawm Physical Vapor Deposition (PVD) lossis Chemical Vapor Deposition (CVD). Cov txheej no feem ntau muaj qhov tuab ntawm 1 txog 5 μm, nrog rau qhov nyuaj microhardness siab (>2000 HV), coefficient qis ntawm kev sib txhuam (<0.3), kev ruaj khov thermal zoo heev, thiab kev sib txuas lus zoo interfacial - ua rau lub neej kev pabcuam thiab kev ua haujlwm ntawm cov ntaub ntawv substrate ntev dua.
Tsis yog tsuas yog ua haujlwm ua ib qho "npog" saum npoo xwb, cov txheej tawv tawv tau tsim los nrog cov qauv txheej zoo tshaj plaws, cov ntaub ntawv xaiv, thiab cov txheej txheem lo rau cov khoom siv substrate. Qhov no ua rau cov txheej tawv tawv tiv taus cov xwm txheej ua haujlwm nyuaj thaum tib lub sijhawm muab kev tiv thaiv kev hnav, kev ruaj khov thermal, thiab kev tiv thaiv xeb.
No.2 Cov Ntsiab Cai Ua Haujlwm ntawm Kev Txheej Txheem Nyuaj
Cov txheej txheem tawv feem ntau yog tso los ntawm kev siv ob txoj hauv kev tseem ceeb: Physical Vapor Deposition (PVD) thiab Chemical Vapor Deposition (CVD).
1. Kev Tso Pa Tawm Hauv Lub Cev (PVD)
PVD yog ib qho txheej txheem uas siv lub tshuab nqus tsev uas cov khoom siv txheej yog evaporation, sputtering, lossis ionization thiab tso ib zaj duab xis nyias rau ntawm qhov chaw substrate. Cov txheej txheem feem ntau muaj xws li:
Cov khoom siv evaporation los yog sputtering
Kev thauj mus los ntawm theem vapor: Atoms / ions tsiv mus rau hauv ib puag ncig nqus tsev
Kev tsim zaj duab xis: Kev sib sau ua ke thiab kev loj hlob ntawm cov txheej tuab ntawm lub substrate
Cov txheej txheem PVD feem ntau suav nrog:
Kev Ua Kom Sov Los Ntawm Thermal
Magnetron Sputtering
Arc Ion Txheej
2. Kev Tso Pa Tshuaj Lom (CVD)
CVD cuam tshuam txog kev tso cov pa roj ua ntej ntawm qhov kub siab kom ua rau muaj kev sib xyaw ua ke ntawm qhov chaw substrate, tsim cov txheej khov kho. Txoj kev no yog qhov tsim nyog rau cov txheej txheem ruaj khov xws li TiC, TiN, thiab SiC.
Cov yam ntxwv tseem ceeb:
Muaj zog lo rau substrate
Muaj peev xwm los tsim cov txheej txheej tuab heev
Kev ua haujlwm kub siab uas xav tau cov khoom siv tiv taus cua sov
Cov Xwm Txheej Thov No.3
Hauv cov chaw ua haujlwm uas muaj kev thauj khoom ntau thiab kev ua haujlwm ntau zaus, cov khoom sib xyaw raug kev sib txhuam, xeb, thiab thermal shock. Cov txheej tawv tsim cov txheej tiv thaiv uas muaj zog, tsis sib txhuam, thiab ruaj khov thermal uas ua rau cov khoom ua haujlwm zoo dua thiab siv tau ntev dua:
Cov Cuab Yeej Txiav: Cov txheej txheej xws li TiAlN thiab AlCrN txhim kho kev tiv taus cua sov thiab kev ua haujlwm hnav zoo heev, ntev lub neej ntawm cov cuab yeej los ntawm 2 txog 5 zaug, txo cov kev hloov pauv ntawm cov cuab yeej, thiab txhim kho kev ua haujlwm sib xws.
Cov pwm thiab cov xuas nrig: TiCrAlN thiab AlCrN txheej txo qhov hnav, galling, thiab thermal qaug zog tawg - txhim kho lub neej pwm kev pabcuam, qhov zoo ntawm ib feem, thiab txo qhov tsis ua haujlwm.
Cov Cheebtsam Tsheb: DLC (Pob Zeb Diamond-Like Carbon) txheej rau ntawm cov khoom xws li tappets, piston pins, thiab valve lifters txo qis kev sib txhuam thiab kev hnav, ntev lub sijhawm hloov pauv, thiab txhim kho kev siv roj.
3C Cov Khoom Siv Hluav Taws Xob: TiN, CrN, thiab lwm yam txheej txheem tawv kho kom zoo nkauj ntawm cov xov tooj ntse thiab cov koob yees duab bezels muab kev tiv thaiv khawb thiab kev tiv thaiv xeb thaum khaws cia cov xim hlau rau kev paub zoo dua rau tus neeg siv.
