Kodi resistant evaporation source coating ndi chiyani?

Resistance evaporation source coating ndi njira yoyambira yokutira ya vacuum evaporation. "Evaporation" imatanthawuza njira yochepetsera filimu yokonzekera yomwe ❖ kuyanika m'chipinda chosungiramo mpweya kumatenthedwa ndi kutenthedwa, kotero kuti maatomu kapena mamolekyu amawuka ndikuthawa kuchokera pamwamba, kupanga chodabwitsa chotuluka cha nthunzi, chomwe chinachitika pamwamba pa 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 kuti mawonekedwe oyenera evaporation gwero, amene yodzaza ndi zipangizo kuti chamunthuyo, tiyeni mpweya otaya mwa, mwachindunji kutentha ndi nthunzi zinthu chamunthuyo zipangizo, kapena kuika zipangizo kuti chamunthuyo mu aluminayamu ndi evaporation gwero la evaporation ndi ena evaporation. Iyi ndi njira yochepetsera kutentha kwa mpweya.

Themakina opaka vacuum evaporationkutenthedwa ndi kutenthedwa ndi chotenthetsera 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 zofunika zotsika pakuyika kwapamwamba. 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 chowotchayo ndi waufupi. M'zaka zaposachedwa, kuti apititse patsogolo moyo wa gwero la kukana evaporation, fakitale ya zida yatengera zinthu zopangira ceramic zopangidwa ndi boron nitride yokhala ndi moyo wautali ngati gwero la evaporation. Malinga ndi lipoti la ku Japan patent, limatha kugwiritsa ntchito zida zopangidwa ndi 20% ~ 30% boron nitride ndi zida zosinthira zomwe zitha kusakanikirana kuti zipange evaporation gwero (crucible), ndikuphimba pamwamba pake ndi wosanjikiza wa zirconium wokhala ndi 62% ~ 82%, ndipo ena onse ndi zida za alloy zirconium-silicon.
