Ib Txoj Kev Kho Nto Rau Cov Roj Koob ntawm Cov Roj Txhaj Tshuaj Tshiab

Ua raws li cov kauj ruam hauv qab no:

1) Ultrasonic tu cov roj koob nrog hlau degreasing tus neeg sawv cev rau 30 feeb, thiab ces ziab;

2) Pre-sputter tu
Cov koob tshuaj ntxuav thiab qhuav roj tau muab tso rau hauv lub tshuab nqus tsev ntawm qhov chaw kaw qhov tsis sib npaug magnetron sputtering ion plating cov cuab yeej, thiab ion sputtering tu yog ua rau 30 mus rau 60 feeb;

3) Txheej
Nyob rau hauv lub tshuab nqus tsev chamber ntawm lub kaw-field unbalanced magnetron sputtering ion plating cov cuab yeej, cov roj koob yog sputtered nrog hlau atoms rau 10 mus rau 20 feeb los tsim ib tug kev hloov txheej ntawm ntshiab hlau atoms, thiab cov carbon atoms yog sputtered nrog hlau atoms rau 50. mus rau 80 feeb. Atom sputtering los tsim cov txheej txheem gradient, hlau atom sputtering thiab carbon atom sputtering rau 90 mus rau 120 feeb los tsim ib nano-multilayer amorphous carbon zaj duab xis doped nrog kab hlau atoms;

Cov hlau atoms uas tau hais tseg no yog chromium Cr, lossis titanium Ti, lossis zirconium Zr, lossis nyiaj.

4.Txoj kev kho saum npoo ntawm cov koob tshiab roj injector koob raws li daim ntawv thov 3, tshwj xeeb hauv qhov ntawd: hauv cov kauj ruam 2), argon yuav tsum tau nkag mus rau hauv lub tshuab nqus tsev chamber nrog purity ntawm 99.99% thiab tus nqi ntws ntawm 25 ~ 35 sccm .

5. Txoj kev kho saum npoo ntawm cov koob tshiab roj injector koob raws li daim ntawv thov 4, tshwj xeeb hauv qhov hais tias: hauv cov kauj ruam 3), argon roj yuav tsum tau nkag mus rau hauv lub tshuab nqus tsev chamber nrog purity ntawm 99.99% thiab tus nqi ntws ntawm 15 ~ 30. sccm ua.
