Raws li kev tsim khoom niaj hnub no tseem xav tau kev ua tau zoo dua los ntawm cov khoom, tshwj xeeb tshaj yog cov uas ua haujlwm nyob rau hauv cov xwm txheej hnyav xws li kub siab, siab siab, thiab kev sib txhuam muaj zog, cov txheej txheem txheej txheem tau dhau los ua qhov tseem ceeb heev. Kev siv cov txheej txheem tawv ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov cuab yeej ua haujlwm ntev, kev ua haujlwm raug, thiab kev ua haujlwm ntawm cov khoom tag nrho. PVD (Physical Vapor Deposition) kev kho qhov chaw yog qhov tseem ceeb ntawm kev tsim kho tshiab hauv daim teb no, tsav tsheb kev nce qib hauv cov txheej txheem txheej txheem.
No.1 Cov Txheej Txheem PVD yog dab tsi?
Cov txheej txheem PVD siv cov txheej txheem lub cev los hloov cov khoom siv txheej los ntawm cov khoom khov lossis cov kua mus rau hauv cov roj, tom qab ntawd tso lawv rau ntawm qhov chaw ntawm cov khoom siv los ntawm kev tso pa tawm kom tsim tau cov txheej txheem sib xws, tawv, thiab ruaj khov. Piv nrog rau cov tshuaj lom neeg vapor deposition (CVD), qhov zoo tshaj plaws ntawm PVD yog nws lub peev xwm tso cov txheej txheem ntawm qhov kub qis dua, tswj cov tuab thiab cov khoom sib xyaw, thiab nws tus cwj pwm zoo rau ib puag ncig thiab txuag hluav taws xob.
No.2 Cov txiaj ntsig ntawm PVD hauv Cov Txheej Txheem Tawv
Vim nws cov txiaj ntsig tshwj xeeb, PVD thev naus laus zis tau lees paub dav hauv kev siv cov txheej txheem tawv, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas xav tau kev tawv siab, kev tiv thaiv kev hnav zoo heev, thiab kev tiv thaiv kev xeb zoo heev. Cov txiaj ntsig tseem ceeb ntawm cov txheej txheem PVD suav nrog:
1. Kev Nyuaj Siab thiab Kev Tiv Thaiv Hnav
Cov txheej PVD tawv ua rau cov khoom tawv dua. Los ntawm kev tso cov khoom siv xws li TiN (Titanium Nitride), TiAlN (Titanium Aluminium Nitride), thiab CrN (Chromium Nitride), qhov tawv ntawm cov txheej tuaj yeem ncav cuag 25GPa–63GPa lossis siab dua. Cov txheej tawv no ua rau zoo dua qhov hnav tsis kam, txo qhov puas ntawm qhov chaw, ua rau muaj kev tiv thaiv oxidation, thiab ntev lub neej kev pabcuam ntawm cov cuab yeej, pwm, thiab lwm yam khoom.
2. Kev Tiv Thaiv Kub Siab Zoo heev
Cov txheej PVD ua rau muaj kev tiv taus kub siab heev, ua rau lawv zoo tagnrho rau cov khoom uas raug kub heev thiab kev sib txhuam siab lossis kev xeb tshuaj lom neeg. Piv txwv li, TiAlN txheej tsis yog tsuas yog muab qhov nyuaj tshwj xeeb xwb tab sis kuj tseem tswj tau qhov ruaj khov ntawm qhov kub siab, ua rau lawv siv dav hauv cov cuab yeej txiav thiab pwm rau cov ntawv thov machining kub siab.
3. Kev Sib Txhuam Qis Rau Kev Ua Haujlwm Zoo Dua
Cov txheej PVD pab ua kom muaj kev sib txhuam tsawg heev, txo cov khoom siv sib txhuam thiab kev hnav, uas ua rau kev ua haujlwm zoo dua thiab qhov zoo ntawm qhov chaw. Qhov no yog qhov tshwj xeeb tshaj yog rau kev ua haujlwm raug thiab cov txheej txheem txiav ceev.
4. Ib puag ncig zoo thiab ua haujlwm tau zoo heev
Piv rau cov txheej txheem txheej txheem ib txwm muaj, cov txheej txheem PVD tsis tas yuav siv cov tshuaj lom neeg ntau, ua rau nws yog ib qho thev naus laus zis uas tsis ua rau ib puag ncig puas tsuaj. Tsis tas li ntawd, cov khoom siv txheej txheem PVD ua haujlwm tau zoo, ua rau muaj kev tso tawm sai sai kom ua tau raws li qhov xav tau ntau lawm.
No.3 Daim Ntawv Thov ntawm PVD Hard Coating
Cov tshuab PVD Hard Coating rau cov txheej tawv yog siv dav hauv kev lag luam uas xav tau kev ua haujlwm zoo dua. Qee qhov chaw tseem ceeb ntawm kev siv suav nrog:
1. Cov Cuab Yeej Txiav thiab Cov Pwm
Hauv kev tsim cov cuab yeej thiab pwm, tshwj xeeb tshaj yog rau cov cuab yeej txiav uas raug rau qhov kub thiab txias siab thiab kev sib txhuam, PVD txheej txheem ua rau muaj kev tiv thaiv kev hnav, kev tiv thaiv kev xeb, thiab kev tawv. TiN txheej txheem feem ntau siv rau hauv cov cuab yeej tig, cov tshuab txiav milling, thiab cov tshuab laum, thaum TiAlN txheej txheem siv dav hauv kev txiav ceev ceev, txhim kho kev ua haujlwm ntawm cov cuab yeej txiav thiab lub neej ua haujlwm.
2. Cov Khoom Siv Tsheb
Rau cov khoom siv cav tsheb xws li lub tog raj kheej, pistons, thiab valves, PVD tawv txheej muaj kev tiv taus kub thiab tiv taus hnav zoo heev, txo qhov kev sib txhuam, ua kom lub neej ntawm cov khoom ntev dua, thiab txhim kho kev ua haujlwm ntawm lub tsheb tag nrho.
