Cov Hom Phaj Rau Hom Tshuaj Txhuam Hniav

Cov khoom siv hauv hluav taws xob siv hauv txhua qhov ntawm lub neej. Feem ntau ntawm cov khoom siv hauv hluav taws xob yuav tsum tau muab tso ua ntej lawv muab tso rau hauv kev ua lag luam. Tam sim no feem ntau siv cov tshuab nqus tsev co khoom siv yog magnetron sputtering nqus plua plav txheej tshuab. Thiab feem ntau yog lub hom phiaj uas siv rau hauv cov tshuab raj yog feem ntau peb hom: hlau lub hom phaj, kev phom sij ntawm lub hom phiaj thiab cov ntsiab lus hauv cov dej num.

Muaj ntau cov ntaub ntawv rau HDDs. Ib zaj duab xis multilayer yog siv rau cov ntaubntawv povthawj nto thiab txhua zaj duab xis nws muaj nws txoj haujlwm. Nyob rau hauv qab txheej, muaj 40-nm-thick chromium lossis chromium alloy zaj duab xis yog siv los txhim khu qhov zoo adhesion thiab zoo corrosion kuj. Thiab lub 15nm-thick cobalt-chromium alloy zaj duab xis yog ces plated nyob nruab nrab thiab 35nm-tuab cobalt alloy zaj duab xis yog coated li ib cov khoom siv hlau nplaum uas tuaj yeem siab nqus cov khoom sib nqus thiab cov kev cuam tshuam tsawg. Thaum kawg, lub 15nm-tuab carbon zaj duab xis yog coated.

Lub hom phiaj ntawm kev sib nqus feem ntau yog hlau nickel alloy, thiab tom qab ntawd, qee cov khoom tshiab, xws li iron nitride, antimony nitride, aluminium nitride, thiab lwm yam. Cov no yog txhua yam zoo nkauj sib nqus dielectric zaj duab xis lub hom phaj.

CD discs yuav coated nrog txhuas zaj duab xis ua ib tug paab txheej ntawm cov yas workpiece, tiam sis rau CDROM thiab DVDROM, txhuas zaj duab xis tsis ua hauj lwm, vim tias yuav muaj ib txheej xim rau cov discs, cov khoom siv saum toj no muaj qee qhov degree ntawm corrosiveness rau txhuas , thiab nws yog hloov los ntawm ib zaj duab xis kub los yog ib cov duab nyiaj.

Qhov txheej ntawm qhov muag kho disk kuj yog tsim ntawm ntau cov khaubncaws sab nraud povtseg. Lub 30-nm-tuab hlau-cobalt alloy cov ntaubntawv povthawj txheej txheej coated ntawm cov txheej xim muaj qee lub ntiaj teb tsis tshua hloov lub cim, thiab tom qab ntawd 20 mus rau 100-nm-tuab silicon nitride dielectric txheej yog coated rau nws. Thaum kawg, ib qho txhuas kev txheej txheem coated.

Cov khoom siv ua hluav taws xob no yuav tsum tau sib nqus cov ntaub ntawv sib luag rau cov ntaub ntawv khaws tseg, thiab nws yog tiav los ntawm kev tua cov txheej nrog ntau yam ntaub ntawv sib txawv.
