Uburyo PVD ikora: Kumenya amabanga yubu buhanga bwo Gutema
Urwego rwo guteza imbere ikoranabuhanga ruhora rutera imbere, rutanga ibisubizo bishya mubikorwa bitandukanye. Imwe muntambwe nkiyi ni tekinoroji ya PVD (Physical Vapor Deposition), izana urwego rushya mubuhanga bwububiko. Muri iyi nyandiko ya blog, tuzareba cyane muburyo PVD ikora tunashakisha uburyo ubwo buhanga budasanzwe buhindura ibintu byinshi.
PVD, nkuko izina ribigaragaza, bikubiyemo gushyira firime yoroheje hejuru yimiterere ikoresheje inzira ifatika. Tekinoroji ikoresha amahame yihariye kugirango izamure igihe kirekire, imikorere nuburanga bwibicuruzwa bitandukanye. Noneho, reka dufate cyane muburyo PVD ikora kandi twumve icyo bivuze.
Intangiriro ya PVD nugukora ibidukikije mumyanya yabugenewe. Iki cyuho gikuraho ibyanduye byose, bitanga ibidukikije byiza kubikorwa byo gutwikira. Icyumba cya hermetic kimaze gufungwa, ibikoresho bigenewe (bishobora kuba ibyuma, ibivanze, ceramic cyangwa na polymer) bikorerwa ubushyuhe bukabije. Nkigisubizo, atome cyangwa molekile mubintu bigenewe bihinduka leta ya gaze.
Noneho haje igice cyingenzi cyukuntu PVD ikora - kubitsa atome ya gaze cyangwa molekile hejuru yikintu cyifuzwa. Kugirango ubigereho, birakenewe ingufu nyinshi nka arc cyangwa plasma. Izi mbaraga zitanga ibisasu kuri atome, bigatuma zisenyuka zigakora igicu cya plasma. Igicu cya plasma noneho gisunika atome yerekeza hejuru, aho atome yegeranya igakora firime yoroheje.
Inzira ya PVD itanga ibyiza byinshi muburyo bwa gakondo. Ubwa mbere, yemerera kugenzura neza ubunini nuburinganire bwa firime yabitswe. Ababikora barashobora kugera kuri coatings hamwe nuburinganire buhebuje, ndetse no kumiterere igoye nibisobanuro birambuye. Icya kabiri, firime ya PVD ifatanye neza na substrate, itanga kuramba no kwambara. Byongeye kandi, tekinoroji ya PVD ituma hashyirwaho ibifuniko bifite imiterere yihariye nko gukomera cyane, guterana gake hamwe no kurwanya ruswa.
Ikoreshwa rya PVD ni ryinshi kandi ririmo inganda zitandukanye. Kuva mu bice by'imodoka n'ibikoresho byo gukata kugeza kurimbisha ibikoresho nibikoresho byubuvuzi, iri koranabuhanga rihindura uburyo dukorana nibicuruzwa bya buri munsi. Kurugero, impuzu za PVD kubikoresho byo gukata zirashobora kwagura cyane umurimo wazo, bikagabanya gukenera gusimburwa kenshi. Mu buryo nk'ubwo, ibishishwa bya PVD ku bice by'imodoka byongera igihe kirekire kandi bikora neza, bifasha kuzamura ubukungu bwa peteroli no kugabanya ibyuka bihumanya.
Vuba aha byagaragaye ko abahanga barimo gushakisha uburyo PVD ikora mumbaraga zidasanzwe. Mugukoresha ibishishwa bya PVD kumirasire yizuba, abashakashatsi bagamije kongera imikorere yabo nubuzima bwabo bwose. Mu buryo nk'ubwo, ibishishwa bya PVD ku byuma by’umuyaga birashobora kongera imbaraga zo kurwanya isuri, bityo umusaruro ukiyongera.
Ihame ryukuntu PVD ikora nudushya twinshi twahinduye ubwubatsi bwubutaka. Mugucunga neza no kubitsa firime yoroheje, impuzu za PVD zongerera igihe kirekire, imikorere nubwiza bwibicuruzwa bitandukanye. Hamwe nibikorwa bitandukanye bitandukanye mu nganda, ubu buhanga bugezweho bukomeje gutanga inzira yiterambere. Mukomeze mutegure mugihe dushyira ahagaragara ibintu byinshi bishimishije mubuvumbuzi bwa PVD.
