Intangiriro y'ihame rya PVD

ntroduction:

Mwisi yisi yubuhanga buhanitse, Ububiko bwa Vapor Deposition (PVD) bugaragara nkuburyo bwo kujya muburyo bwo kuzamura imikorere nigihe kirekire cyibikoresho bitandukanye. Wigeze wibaza uburyo ubu buhanga bugezweho bukora? Uyu munsi, twinjiye mubukanishi bukomeye bwa PVD, dutanga ibisobanuro byuzuye kubikorwa byayo nibyiza bitanga. Soma kugirango umenye imikorere yimbere ya PVD nakamaro kayo mubikorwa bitandukanye.

Gusobanukirwa PVD:

Imyuka ya Vapor Deposition, ikunze kwitwa PVD, ni tekinike yo kubitsa firime yoroheje ikubiyemo kwimura atome cyangwa molekile ziva mumasoko akomeye zijya hejuru hakoreshejwe uburyo bwumubiri. Ubu buhanga bukoreshwa cyane mu kuzamura ubuso bwibikoresho bitandukanye, nkibyuma, plastiki, ububumbyi, nibindi byinshi. Inzira ya PVD ikorwa mugihe cya vacuum, igenzura neza kugenzura imiterere ya firime yoroheje.

Inzira ya PVD:

Inzira ya PVD irashobora gushyirwa mubice bine byingenzi: gutegura, guhumeka, kubitsa, no gukura. Reka dusuzume buri cyiciro muburyo burambuye.

1. Gutegura:

Mbere yo gutangiza uburyo bwo kubitsa, ibikoresho bigomba gutwikirwa bisukurwa neza. Iyi ntambwe yemeza ko ubuso butarangwamo umwanda, nk'amavuta, ibice bya oxyde, cyangwa ibice by'amahanga, bishobora kubangamira gufatana. Ubuso bwera ningirakamaro kugirango umuntu agere ku bwiza bwo hejuru kandi igihe kirekire cyo kubaho.

2 Guhumuka:

Muri iki cyiciro, ibikoresho byakoreshejwe mu gukora igifuniko, byitwa inkomoko, biva mu kirere. Ibikoresho byatanzwe bishyirwa mu cyumba cya vacuum, aho gikorerwa ingufu zumuriro cyangwa amashanyarazi. Nkigisubizo, atome cyangwa molekile ziva mubikoresho biva mu kirere ziva mu kirere, bigakora flux.

3. Kubitsa:

Iyo ibikoresho biva mu kirere bimaze guhumeka, imyuka inyura mu cyumba cya vacuum ikagera ku buso bwa substrate. Substrate, akenshi ibikoresho bigomba gutwikirwa, ishyizwe hafi yinkomoko yumwuka. Kuri ubu, ibice byumwuka byinjira hejuru yubutaka bwa substrate, bikaviramo gushira firime yoroheje.

4. Gukura:

Hamwe na atome cyangwa molekile igwa kuri substrate, firime yoroheje ikura buhoro buhoro. Imbaraga ziyi nzira yo gukura zirashobora gukoreshwa muguhindura ibipimo nkigihe cyo kubitsa, ubushyuhe, nigitutu. Ibipimo bifasha kugenzura uburebure bwa firime, uburinganire, hamwe nibigize, amaherezo biganisha kumiterere yihariye kugirango ihuze ibisabwa byihariye.
