Igipfundikizo cy'isoko ry'ubudahangarwa bw'umwuka ni iki?

Gusiga irangi ry’imvange yo mu kirere ni uburyo bw’ibanze bwo gusiga irangi ry’imvange yo mu kirere. “Gusuka irangi” bivuga uburyo bwo gutegura irangi ryoroheje aho ibikoresho byo gusiga mu cyumba cy’imvange bishyuha kandi bigahinduka umwuka, kugira ngo atome cyangwa molekile by’ibikoresho bihinduke umwuka kandi bive hejuru, bikore ikintu gitera umwuka, bibe ku buso bw’imvange cyangwa imvange, hanyuma bibe bifunze neza kugira ngo bikore irangi rikomeye.

Uburyo bwo gusiga imvange y’amazi hakoreshejwe uburyo bwa resistance evaporation source coating ni ugukoresha tantalum, molybdenum, tungsten n’ibindi byuma bifite aho bishongesha cyane kugira ngo hakorwe ishusho ikwiye y’imvange y’amazi, irimo ibikoresho bigomba gukurwamo amazi, kureka umwuka ugacamo, gushyushya no gutwika ibikoresho byakuwemo amazi, cyangwa gushyira ibikoresho bigomba gukurwamo amazi muri alumina, beryllium oxide n’ibindi bikoresho bikoreshwa mu gushyushya no gutwika amazi mu buryo butaziguye. Ubu ni uburyo bwo gushyushya amazi hakoreshejwe resistance evaporation.

Itsindaimashini ikoresha icyuma gikingira umwuka gikoresha icyuma gishyushyaIshyushya kandi igakurwamo umwuka hakoreshejwe icyuma gishyushya gifite ibyiza byo kuba imiterere yoroshye, ihendutse kandi ikoreshwa neza. Ishobora gukoreshwa mu gutwikira ibikoresho bifite aho bishongesha cyane, cyane cyane mu gukora ibintu byinshi bifite ibisabwa bike kugira ngo irangi ribe ryiza. Kugeza ubu, haracyari uburyo bwinshi bwo gutwikira ibikoresho bifite aho biboherwa no gukurwamo umwuka bukoreshwa mu gukora indorerwamo zifite aluminiyumu.

Ingaruka mbi zo gukoresha uburyo bwo gusiga irangi ry’ingufu ziterwa n’ubushyuhe ni uko ubushyuhe ntarengwa bushobora kugerwaho hakoreshejwe ubushyuhe ari buke, kandi igihe cyo gukoresha ubushyuhe nacyo kikaba gito. Mu myaka ya vuba aha, kugira ngo habeho ubuzima bwiza bw’irangi riterwa n’ubushyuhe, uruganda rw’ibikoresho rwakoresheje ibikoresho bya keramike bikozwe na boron nitride bimara igihe kirekire nk’isoko y’ubushyuhe. Nk’uko raporo y’ipatanti y’Abayapani ibigaragaza, rushobora gukoresha ibikoresho bigizwe na boron nitride 20% ~ 30% n’ibikoresho birwanya ubushyuhe bishobora guhuzwa nabyo kugira ngo bikore isoko y’ubushyuhe (ishobora gucukurwa), kandi bigasiga hejuru yabyo urwego rwa zirconium rurimo 62% ~ 82%, naho ibindi ni ibikoresho bya zirconium-silicon alloy.
