Txheej Txheem Txheej Txheem thiab Kev Ua Haujlwm Mechanisms cuam tshuam qhov zoo ntawm cov khoom siv zaj duab xis nyias (Part 2)

3. cuam tshuam ntawm substrate kub

Substrate kub yog ib qho tseem ceeb rau kev loj hlob ntawm daim nyias nyias. Nws muab lub zog ntxiv rau cov membrane atoms lossis molecules, thiab feem ntau cuam tshuam rau cov qauv membrane, agglutination coefficient, expansion coefficient thiab aggregation ntom. Lub macroscopic reflection nyob rau hauv zaj duab xis refractive index, tawg, kev nyuaj siab, adhesion, hardness thiab insolubility yuav txawv heev vim qhov txawv substrate kub.

(1) Txias substrate: feem ntau yog siv rau evaporation ntawm hlau zaj duab xis.

(2) Qhov zoo ntawm qhov kub thiab txias:

① Cov roj seem ntawm cov roj molecules adsorbed rau ntawm lub substrate nto yog tshem tawm kom muaj kev sib khi quab yuam ntawm lub substrate thiab cov molecules deposited;

(2) Txhawb kev hloov pauv ntawm lub cev adsorption mus rau chemisorption ntawm zaj duab xis txheej, txhim khu kev sib cuam tshuam ntawm cov molecules, ua rau cov yeeb yaj kiab nruj, ua kom cov adhesion thiab txhim kho cov neeg kho tshuab lub zog;

③ Txo qhov sib txawv ntawm cov vapor molecular recrystallization kub thiab substrate kub, txhim kho qhov ntom ntawm cov zaj duab xis txheej, ua kom cov tawv tawv ntawm cov zaj duab xis txheej kom tshem tawm cov kev ntxhov siab sab hauv.

(3) Qhov tsis zoo ntawm qhov kub thiab txias heev: cov qauv ntawm cov txheej txheem ntawm zaj duab xis hloov los yog cov khoom siv zaj duab xis decomposes.

4. Cov teebmeem ntawm ion bombardment

Bombardment tom qab plating: txhim kho cov aggregation ceev ntawm cov zaj duab xis, txhim khu cov tshuaj tiv thaiv, ua rau kom lub refractive index ntawm oxide zaj duab xis, txhua yam muaj zog thiab kuj thiab adhesion. Lub teeb puas pib nce.
5. Kev cuam tshuam ntawm cov khoom siv substrate

(1) sib txawv expansion coefficient ntawm substrate khoom yuav ua rau txawv thermal stress ntawm zaj duab xis;

(2) Cov tshuaj lom neeg sib txawv yuav cuam tshuam rau adhesion thiab firmness ntawm zaj duab xis;

(3) Lub roughness thiab tsis xws luag ntawm lub substrate yog lub ntsiab qhov chaw ntawm nyias zaj duab xis scattering.
6. Kev cuam tshuam ntawm substrate tu

Qhov seem ntawm cov av thiab cov tshuaj detergent nyob rau saum npoo ntawm lub substrate yuav ua rau: (1) adhesion tsis zoo ntawm zaj duab xis rau lub substrate; ② Kev nqus dej ntau ntxiv, lub peev xwm los tiv thaiv laser tsis zoo; ③ Lub teeb kis tau tus mob tsis zoo.

Cov tshuaj muaj pes tsawg leeg (purity thiab impurity hom), lub cev lub cev (hmoov los yog thaiv), thiab pretreatment (nqus sintering los yog forging) ntawm cov ntaub ntawv zaj duab xis yuav cuam tshuam rau cov qauv thiab kev ua tau zoo ntawm cov zaj duab xis.

8. Kev cuam tshuam ntawm evaporation txoj kev

Thawj lub zog kinetic muab los ntawm cov txheej txheem evaporation sib txawv rau vaporize molecules thiab atoms yog qhov sib txawv heev, ua rau muaj qhov sib txawv loj hauv cov qauv ntawm cov yeeb yaj kiab, uas tau tshwm sim raws li qhov sib txawv ntawm qhov ntsuas refractive, tawg thiab adhesion.

9. Kev cuam tshuam ntawm vapor tshwm sim Angle

Lub vapor tshwm sim Angle yog hais txog lub kaum sab xis ntawm lub vapor molecular hluav taws xob kev taw qhia thiab qhov chaw ib txwm muaj ntawm coated substrate, uas cuam tshuam rau cov yam ntxwv ntawm kev loj hlob thiab kev sib sau ntom ntom ntawm zaj duab xis, thiab muaj kev cuam tshuam zoo rau qhov ntsuas refractive thiab tawg cov yam ntxwv ntawm zaj duab xis. Txhawm rau kom tau txais cov yeeb yaj kiab zoo, nws yog qhov tsim nyog los tswj lub kaum sab xis ntawm tib neeg emission ntawm vapor molecules ntawm cov khoom siv zaj duab xis, uas feem ntau yuav tsum tau txwv rau 30 °.

10. Cov teebmeem ntawm ci kev kho mob

Kev kho cua sov ntawm cov yeeb yaj kiab hauv cov cua yog qhov tsim nyog rau kev tawm tsam kev ntxhov siab thiab thermal tsiv teb tsaws ntawm ambient gas molecules thiab cov yeeb yaj kiab molecules, thiab tuaj yeem ua rau cov qauv ntawm cov yeeb yaj kiab recombination, yog li nws muaj kev cuam tshuam zoo rau lub refractive Performance index, kev nyuaj siab thiab hardness ntawm zaj duab xis.
