Qhov zoo ntawm lub tshuab nqus tsev tshuab carbide txheej:

Qhov zoo ntawm lub tshuab nqus tsev tshuab carbide txheej:

1) Vim tias cov khoom siv txheej txheej ntawm qhov chaw muaj qhov nyuaj heev thiab hnav tsis kam, piv nrog cov cemented carbide tsis muaj coated, coated cemented carbide tso cai rau kev txiav nrawm dua, yog li txhim kho kev ua haujlwm zoo; los yog Txhim kho cov cuab yeej ua haujlwm tau zoo ntawm tib qhov kev txiav ceev.

2) Txij li cov kev sib txhuam coefficient ntawm cov txheej txheej thiab cov khoom yuav tsum tau ua yog me me, lub txiav quab yuam ntawm cov hniav coated yog txo mus rau ib tug npaum li cas piv nrog lub uncoated hniav.

3) Thaum cov hniav coated yog ua tiav, qhov zoo ntawm cov txheej txheem saum npoo zoo dua.

4) Vim muaj kev ua tau zoo, cov hniav coated muaj ntau yam zoo dua. Ib qib coated ntawm cov hniav muaj ntau yam kev siv.

Lub tshuab nqus tsev txheej yuav raug txuas rau saum npoo ntawm cov khoom coated los ntawm ntshiab txhuas

Lub sijhawm no, cov txheej txheej tsim tuaj yeem poob nws cov luster vim cov roj seem tseem muaj nyob hauv cov khoom zoo txhuas, uas tseem yuav txo qhov adhesion ntawm txheej thiab primer. Piv txwv li, thaum lub tshuab nqus tsev kawm ntawv siab thiab qhov kub thiab txias ntawm tungsten hlau kuj siab, lub zog kinetic ntawm evaporating aluminium kuj yuav nce, thiab qhov saum npoo ntawm cov coated yuav yog cov ntshiab txhuas (tsis muaj roj seem), thiab qhov ntom ntom. siab heev. Thiab tau txais kev txhim kho (nrog rau adhesion, thiab lwm yam).

Kev ua tau zoo ntawm lub tshuab nqus tsev txheej tshuab txheej kuj hloov ntxiv rau kev hloov pauv

Yog li ntawd, thaum lub tungsten hlau yog teem raws li ib tug taag naj npawb, los ntawm lub degree ntawm lub tshuab nqus tsev mus rau lub scattering kev taw qhia ntawm evaporated txhuas, qhov kub ntawm cov tungsten hlau, qhov kev ncua deb ntawm lub tungsten hlau mus rau qhov yuav tsum tau plated, thiab lwm yam.; Raws li nws cov txheej txheem txheej txheej, kev ua haujlwm ntawm cov txheej txheem kuj hloov pauv ntxiv rau kev hloov pauv. Raws li tau hais los saum toj no, txheej txheej yog nqa tawm ntawm 10 - 4 Torr. Yog tias lub tshuab nqus tsev qis dhau lawm, cov txhuas hauv cov evaporation ntsib cov roj seem lossis cov roj uas tsim tawm thaum lub tungsten hlau yog cua sov, thiab kev sib tsoo tshwm sim thiab txias. Aluminium particles (tag nrho ntawm cov khoom me me ntawm txhuas) yuav ua raws li qhov yuav tsum tau coated.
