Kodi resistant evaporation source coating ndi chiyani?

Resistance evaporation source coating ndi njira yoyambira yokutira ya vacuum evaporation."Evaporation" imatanthawuza njira yopyapyala yokonzekera filimu momwe zinthu zokutira zomwe zili m'chipinda cha vacuum zimatenthedwa ndikuwuka, kotero kuti maatomu kapena mamolekyu amawuka ndikutuluka pamwamba, ndikupanga chodabwitsa cha kutuluka kwa nthunzi, zomwe zimachitika pamwamba pa mlengalenga. gawo lapansi kapena gawo lapansi, ndipo pamapeto pake amafupikitsidwa kuti apange filimu yolimba.

Otchedwa kukana evaporation gwero ❖ kuyanika njira ndi ntchito tantalum, molybdenum, tungsten ndi zitsulo zina mkulu kusungunuka zitsulo kupanga mawonekedwe oyenera evaporation gwero, amene yodzaza ndi zipangizo kuti nthunzi, lolani mpweya kuyenda, mwachindunji kutentha ndi. sungunulani zinthu zomwe zatuluka nthunzi, kapena ikani zinthuzo kuti zisungunuke mu alumina, beryllium okusayidi ndi ma crucibles ena otenthetsera osalunjika ndi mpweya.Iyi ndi njira yochepetsera kutentha kwa mpweya.

Themakina opaka vacuum evaporationkutenthedwa ndi kutenthedwa ndi chowotcha chotsutsa chimakhala ndi ubwino wa kapangidwe kosavuta, mtengo wotsika komanso ntchito yodalirika.Itha kugwiritsidwa ntchito ngati ❖ kuyanika kwa evaporation ya zinthu zokhala ndi malo otsika osungunuka, makamaka popanga misa yokhala ndi zofunikira zotsika zopangira ❖ kuyanika.Pakalipano, pali njira zambiri zokutira zotetezera kutentha ndi kutuluka kwa nthunzi zomwe zimagwiritsidwa ntchito popanga magalasi opangidwa ndi aluminiyamu.

Zoyipa za kukana evaporation source evaporation coating coating njira ndikuti kutentha kwakukulu komwe kumatha kufikika ndi kutentha kumakhala kochepa, komanso moyo wautumiki wa chotenthetsera umakhalanso waufupi.M'zaka zaposachedwa, kuti apititse patsogolo moyo wa gwero la kukana evaporation, fakitale ya zida yatengera zinthu zopangira ceramic zopangidwa ndi boron nitride zomwe zimakhala ndi moyo wautali ngati gwero la evaporation.Malinga ndi lipoti la ku Japan patent, litha kugwiritsa ntchito zida zopangidwa ndi 20% ~ 30% boron nitride ndi zida zosinthira zomwe zimatha kusakanikirana kuti zipangitse gwero la evaporation (crucible), ndikuphimba pamwamba pake ndi wosanjikiza wa zirconium wokhala ndi 62% ~ 82%, ndipo zina zonse ndi zirconium-silicon alloy alloy.
