kuvura ubushyuhe bwo hejuru
Gutunganya ubushyuhe bwa chimique nuburyo bwo gutunganya ubushyuhe aho igihangano gishyirwa muburyo bwihariye bwo gushyushya no kubika ubushyuhe, kuburyo atome ikora murwego rwohasi yinjira mubutaka bwakazi, bityo bigahindura imiterere yimiterere nimiterere ya hejuru yubuso bwakazi, hanyuma uhindure imikorere. Imiti ivura ubushyuhe nayo ni bumwe muburyo bwo kubona ubukana bwubuso, bukomeye kandi butondetse. Ugereranije no kuzimya hejuru, kuvura ubushyuhe ntabwo bihindura imiterere yicyuma gusa, ahubwo binahindura imiterere yimiti. Ukurikije ibintu bitandukanye byacengewe, kuvura ubushyuhe bwa chimique birashobora kugabanywamo carburizing, nitriding, kwinjira-byinshi, kwinjira mubindi bintu, nibindi. Uburyo bwo kuvura ubushyuhe bwa chimique bukubiyemo ibintu bitatu byingenzi: kubora, kwinjizwa, no gukwirakwizwa.
Ubuvuzi bukoreshwa cyane:
Carburizing, nitriding (bakunze kwita nitriding), karubone (ikunze kwitwa cyanidation na nitriding yoroshye), nibindi.
icyuma
Gupfundikanya icyuma kimwe cyangwa byinshi hejuru yibikoresho fatizo birashobora kunoza cyane imyambarire yacyo, kurwanya ruswa no kurwanya ubushyuhe, cyangwa kubona ibindi bintu bidasanzwe. Hano hari amashanyarazi, isahani yimiti, isahani yububiko, isahani yinjira, isahani ishyushye, guhumeka vacuum, gusasa spray, ion plaque, sputtering nubundi buryo.
Icyuma cya Carbide Coating - Kubika imyuka
Tekinoroji yo kubika imyuka bivuga ubwoko bushya bwa tekinoroji yo gutwika ibika ibintu biva mu byuka birimo ibintu byoherejwe hejuru y’ibikoresho hakoreshejwe uburyo bwa fiziki cyangwa imiti yo gukora firime zoroshye.
Ukurikije ihame ryibikorwa byo kubitsa, tekinoroji yo guta imyuka irashobora kugabanywamo ibyiciro bibiri: kubika imyuka yumubiri (PVD) hamwe nubumara bwa chimique (CVD).
Kubika Umwuka Wumubiri (PVD)
Umwuka wumwuka wumubiri bivuga ikoranabuhanga aho ibintu bihumeka muri atome, molekile cyangwa ioni muri ion hakoreshejwe uburyo bwumubiri mugihe cya vacuum, hanyuma firime yoroheje igashyirwa hejuru yibintu binyuze murwego rwa gaze.
Tekinoroji yo kubitsa kumubiri ikubiyemo uburyo butatu bwibanze: guhumeka vacuum, gusohora, hamwe no gufata ion.
Imyuka yumubiri ifitemo ibintu byinshi byifashishwa mubikoresho bya substrate nibikoresho bya firime; inzira iroroshye, ibika ibikoresho, kandi idafite umwanda; firime yabonetse ifite ibyiza byo kwizirika cyane kuri base ya firime, ubunini bwa firime imwe, guhuza, hamwe na pinhole nkeya.
Kubika imyuka ya shimi (CVD)
Imyuka ya chimique isobanura uburyo gaze ivanze ikorana nubuso bwa substrate ku bushyuhe runaka kugirango ikore firime yicyuma cyangwa ifumbire hejuru yubutaka.
Kuberako firime yimiti ivamo imyuka ifite imbaraga zo kurwanya kwambara, kurwanya ruswa, kurwanya ubushyuhe n amashanyarazi, optique nibindi bintu bidasanzwe, yakoreshejwe cyane mubikorwa byo gukora imashini, ikirere, ubwikorezi, inganda zikora amakara nizindi nganda.
