Gusibanganya irangi, bizwi kandi nka adhesion failure cyangwa peeling, ni ikibazo gikomeye muinzira zo gushyiramo umwuka mu cyuma gifunzeIki kintu kibaho iyo firime yashyizwemo itandukaniye n'igice cy'umubiri, bigahungabanya imikorere n'ubuziranenge bw'imiterere. Gusobanukirwa neza impamvu nyamukuru zayo bisaba isuzuma ryimbitse mu mpande enye z'ingenzi.
1. Ibura ry'ingufu zo gutegura ubuso bw'ubutaka
Ingufu zo hejuru zidahagije: Ingufu nke zo hejuru (urugero, PP, PTFE) zirwanya kunyagirwa neza, bikabuza guhuza neza hagati y’urusobe rw’umubiri. Ingufu zo hejuru ziri munsi ya 40 mN/m akenshi zisaba gukoresha plasma cyangwa gukoresha imiti.
Kugaragara kw'ibisigazwa by'ibisigazwa, amavuta, cyangwa ubushuhe bw'ibisigazwa bitera imiterere y'ibisigazwa idakomeye, bikora nk'ibintu bihumanya ibidukikije bigabanya imbaraga zo gufatana.
Imiterere y'ubutaka idakwiye: Ubuso bworoshye cyane ntibugira aho buhurira n'imashini, mu gihe ubuso bugoye cyane bushobora gutwikira ubwinshi bw'aho buherereye no gutera stress.
2. Uburyo bwo Kunanirwa Bufitanye isano n'Ibikorwa
Ubuziranenge buke bw'umwuka uvamo umwuka: Umuvuduko w'ibanze urenze 5×10⁻⁵ Torr yemerera imyuka isigaye kwinjiramo, bigatuma habaho oxidized interfaces no kugabanya ubushobozi bwo guhuza.
Kuvura Plasma bidahagije: Gukoresha plasma idahagije (imbaraga nke/igihe gito) ntibituma habaho amatsinda ahagije y’imikorere y’ubuso kugira ngo imiti ifatanye.
Ubuhanga mu by'ikoranabuhanga ritari ryo: Kutagira ibice bifasha mu gufatana (urugero, Cr, Ti, cyangwa SiOₓ kuri sisitemu za polimeri z'icyuma) bibuza ihindagurika ry'imiterere y'ibikoresho buhoro buhoro.
3. Ibibazo byo guhuza ibikoresho
Ubudasa bw'ingufu z'ubushyuhe: Itandukaniro rya CTE >5 ppm/°C hagati y'ipamba n'ibumba ritera imbaraga zo hagati y'ubushyuhe mu gihe cy'ihindagurika ry'ubushyuhe, bigatera ivangura rishingiye ku munaniro.
Kudahuza kwa shimi: Kutagira ibikoresho byo guhuza imiterere y’umubiri (urugero, kwirema kwa karubide mu byuma bivanze na ceramic) bituma habaho guhuza umubiri gusa ariko imbaraga zikaba nke.
4. Kutubahiriza ibipimo byo mu igenamigambi
Voltage y’ibiranga idakozwe neza: Bias bias idakwiye ntitanga uburyo buhagije bwo kuvanga no gukora ibizinga.
Ubusembwa buterwa n'igipimo: Igipimo gikabije cyo gushyiramo (> 5 nm/s) gitera gukura kw'inkingi hamwe n'imipaka ifite imyenge, bigagabanya imbaraga zo gufatana.
Amakosa mu gucunga ubushyuhe: Gutandukana kw'ubushyuhe ku gice cyo hasi >15% ugereranyije n'urwego rwiza bigira ingaruka mbi ku bucucike bw'uturemangingo no gukwirakwira kw'urusobe rw'amabara.
Uburyo bwo Kwirinda
Shyira mu bikorwa isuzuma rya plasma mu buryo bwihuse (OES, Langmuir probes) kugira ngo wemeze ko ubuso bukora neza
Kora imiterere y'ibice by'imbere hakoreshejwe uburyo bwo gushyiramo ibintu mu buryo busanzwe
Komeza gukurikiza amabwiriza akomeye yo kugenzura ubwandu (icyumba cyo gusukura ISO Class 6+)
Koresha uburyo bwo kugenzura imiterere y'urumuri rwa quartz mu gihe uri ahantu runaka kugira ngo urebe uko umuvuduko n'ubugari bihagaze
Shyiraho uburyo bwo kugenzura imibare ku bipimo by'ingenzi (umuvuduko, kubogama, ubushyuhe)
Umwanzuro
Gutandukanya irangi bituruka ku gutsindwa kwa gahunda mu byiciro byinshi by’imikorere aho kuba amakosa ya parameter yihariye. Ingamba zikomeye zo gufata neza irasaba kunoza uburyo bwo gutegura substrate, gukora igenamigambi, no gushyiramo ibintu. Binyuze mu kugenzura uburyo bwa chemistry yo hagati y’urusobe rw’ibikoresho no gucunga imihangayiko, inzira zigezweho zo gushyiramo ibintu mu buryo bw’ubusa zishobora kugera ku musaruro uhoraho wo gufata neza irangi urenze 50 MPa ku bikoresho byinshi bivanze.
—Iyi nkuru yasohotse na ibikoresho byo gusiga irangi ry'umwukauruganda rwa Zhenhua Vacuum
