Cov ntawv thov ntawm Lub Tshuab Nqus Tsev Txheej hauv Kev Lag Luam Khoom Siv Kho Mob

Raws li cov khoom siv kho mob hloov zuj zus mus rau qhov tseeb dua, cov txheej txheem tsawg kawg nkaus, thiab kev ua haujlwm ruaj khov, Vacuum Coating Technology tau dhau los ua ib qho txheej txheem hloov kho qhov chaw tseem ceeb. Los ntawm cov txheej txheem xws li Physical Vapor Deposition (PVD), Magnetron Sputtering, thiab Ion Plating, cov khoom siv kho mob tsis tsuas yog ua tiav kev sib raug zoo zoo xwb, tab sis kuj ua tau zoo tiv thaiv kab mob, tiv taus kev hnav, thiab zoo nkauj.

I. Lub Ntsiab Cai ntawm Kev Txheej Txheem Nqus Tsev

Kev txheej txheej siv lub tshuab nqus tsev siv lub tshuab nqus tsev siab thiab cov khoom siv zog (plasma, electron beam, lossis arc discharge) los ua kom cov khoom txheej ua pa lossis sputter rau hauv cov khoom me me, uas tom qab ntawd condense rau ntawm qhov chaw ntawm cov khoom siv kho mob los tsim cov zaj duab xis nyias ua haujlwm. Piv nrog rau kev siv electroplating lossis txau ib txwm muaj, nws cov txiaj ntsig suav nrog:

Dense Microstructure rau kev txhim kho durability

Kev nplaum ruaj khov ntawm zaj duab xis thiab cov khoom siv

Cov Txheej Txheem Zoo Rau Ib Puag Ncig uas tsis muaj cov dej khib nyiab tshuaj lom neeg, ua raws li cov qauv kev tsim khoom ntsuab

II. Cov ntawv thov ntawm Lub Tshuab Nqus Tsev Txheej hauv Cov Khoom Siv Kho Mob
1. Cov Cuab Yeej Phais Mob

Cov Txheej Txheem Feem Ntau: TiN, ZrN, DLC (Pob Zeb Zoo Li Pob Zeb Diamond)

Kev Ua Haujlwm: Txhim kho qhov tawv ntawm qhov chaw thiab kev hnav tsis kam, txo cov coefficient sib txhuam, thiab txuas ntxiv lub neej ua haujlwm ntawm txiab, scalpels, forceps, thiab lwm yam twj paj nruag.

2. Cov Khoom Siv Uas Muab Tso Rau Hauv Tau

Cov Txheej Txheem Feem Ntau: Ti, TiO₂, HA (Hydroxyapatite)

Kev Ua Haujlwm: Ti thiab TiO₂ txheej muab kev sib raug zoo zoo dua thiab txhawb kev sib koom ua ke ntawm cov pob txha. HA txheej txhim kho kev ua haujlwm ntawm qhov chaw, ua rau cov hlwb sib txuas thiab sib txuas cov ntaub so ntswg.

3. Cov Khoom Siv Rau Lub Plawv

Piv txwv li: Stents, cov hlab ntsha plawv cuav

Kev Ua Haujlwm: DLC lossis TiN txheej txo qhov kev sib txhuam hauv cov chaw sib cuag ntshav, txo qhov kev pheej hmoo ntawm thrombosis (cov khoom tiv thaiv thrombogenic), thiab ua kom lub cuab yeej siv tau ntev.

4. Cov Cuab Yeej Kho Hniav

Daim Ntawv Thov: Cov cuab yeej siv kho hniav uas tau txheej TiN, cov khoom siv kuaj hniav uas tau txheej DLC

Kev Ua Haujlwm: Txhim kho qhov kev tiv thaiv corrosion thiab qhov nyuaj ntawm qhov chaw, ua kom muaj kev raug siab dua thiab kev ua haujlwm ntev hauv kev siv kho mob.

5. Cov Tshuaj Tiv Thaiv Kab Mob & Cov Tshuaj Tiv Thaiv

Cov ntaub ntawv: Ag, Cu, ZnO nanocoatings

Txoj Haujlwm: Kev tswj hwm kev tso tawm ion lossis cov teebmeem photocatalytic tiv thaiv kev loj hlob ntawm cov kab mob, txo qis kev pheej hmoo ntawm kev kis kab mob tom qab phais.

III. Cov txiaj ntsig ntawm cov txheej txheem thiab tus nqi lag luam

Kev Tswj Xyuas Zaj Duab Xis Thickness: Precisely adjustable los ntawm ob peb nanometers mus rau ob peb micrometers.

Cov Txheej Txheem Sib Xyaws Ntau Yam: Sib xyaw ua ke qhov kev tiv thaiv kev hnav, cov khoom tua kab mob, thiab kev sib raug zoo hauv ib zaj duab xis.

Muaj Peev Xwm Tsim Khoom Loj: Haum rau kev tsim khoom loj hauv kev lag luam khoom siv kho mob.

IV. Cov Qauv Yav Tom Ntej

Nrog kev nce qib ntawm cov khoom siv kho mob me me thiab ntse, kev txheej tshuab nqus tsev yuav txuas ntxiv kev sib xyaw ua ke ntawm nanotechnology thiab bio-functional coatings, xws li:

Cov txheej txheem tiv thaiv kab mob Nano-silver (Ag) rau kev tswj kev kis kab mob zoo dua

Nano-TiO₂ photocatalytic coatings rau kev ua haujlwm tiv thaiv kab mob mus sij hawm ntev

Cov txheej txheem ua haujlwm rau kev txhim kho kev xa tshuaj zoo dua

Xaus lus

Kev siv lub tshuab nqus tsev tsis yog ib txoj hauv kev los txhim kho qhov zoo nkauj thiab ruaj khov ntawm cov khoom siv kho mob xwb; nws yog ib qho thev naus laus zis tseem ceeb rau kev txhim kho kev nyab xeeb thiab kev ua haujlwm. Txij li cov cuab yeej phais mus rau kev cog hniav, los ntawm stents mus rau cov cuab yeej kho hniav, kev siv lub tshuab nqus tsev twb tau dhau los ua ib qho kev daws teeb meem tseem ceeb hauv kev lag luam kho mob.
