Kurwanya impumuro yo kwihanganira ni iki?

Kurwanya impumuro yumwimerere ni uburyo bwibanze bwo gutwika vacuum. "Evaporation" bivuga uburyo bworoshye bwo gutegura firime aho ibikoresho byo gutwikira mucyumba cya vacuum bishyuha kandi bigahinduka umwuka, kuburyo atome cyangwa molekile yibintu biva mu kirere kandi bigahunga biva hejuru, bigakora ibintu bituruka kumyuka yumuyaga, ibyabaye hejuru yubutaka cyangwa substrate, hanyuma bikaregerana kugirango bibe firime ikomeye.

Uburyo bwitwa anti-evaporation source coating method ni ugukoresha tantalum, molybdenum, tungsten nibindi byuma byo hejuru byo gushonga kugirango habeho imiterere ikwiye yo guhumeka, yuzuyemo ibikoresho bigomba guhumeka, reka umwuka unyure, ushushe kandi uhumure ibikoresho byahumetse hamwe nubushuhe butangwa na alumine, beryllium oxyde. Ubu ni uburyo bwo kurwanya ubushyuhe bwo guhumeka.

Uwitekaimashini itwara vacuumgushyushya no guhumeka nubushyuhe bwo guhangana bifite ibyiza byuburyo bworoshye, igiciro gito no gukoresha neza. Irashobora gukoreshwa muburyo bwo guhumeka ibikoresho bifite aho bishonga cyane cyane kubikorwa byinshi hamwe nibisabwa bike kugirango ubuziranenge bushoboke. Kugeza ubu, haracyari umubare munini wo gutwikira ubushyuhe no guhumeka bikoreshwa mugukora indorerwamo ya aluminiyumu.

Ingaruka zo kurwanya impumuro nziza yo gutwika uburyo bwo gutwika ni uko ubushyuhe ntarengwa bushobora kugerwaho no gushyuha ari buke, kandi ubuzima bwa serivisi bwumushyushya nabwo ni bugufi. Mu myaka yashize, mu rwego rwo kuzamura imibereho y’imyuka irwanya imyuka, uruganda rukora ibikoresho rwakoresheje ibikoresho bya ceramic ceramic byakoreshwaga na nitride ya boron hamwe nubuzima burebure nkisoko yimuka. Raporo y’ipatanti y’Ubuyapani ivuga ko ishobora gukoresha ibikoresho bigizwe na 20% ~ 30% ya nitride ya boron hamwe n’ibikoresho bivunika bishobora guhuzwa nayo kugira ngo ikore isoko y’umwuka (crucible), ikanambika ubuso bwayo hamwe na zirconium irimo 62% ~ 82%, naho ibindi ni ibikoresho bya zirconium-silicon.
