Intambwe mu buhanga bwo kuvura hejuru ni ugusobanura imikorere yaibikoresho birambirana, gusezeranya inyungu zingenzi mubikorwa, kurangiza ubuziranenge, hamwe no kuramba kubikoresho kubakora neza kwisi yose. Gukoresha inzira ya passivation yateye imbere mubudage, ibisekuru bigezweho byibikoresho bitanga paradox idasanzwe: impande zahinduwe na microscopique igabanya ubukana, bwihuse, kandi busukuye kuruta mbere hose.
Mu myaka ibarirwa muri za mirongo, gukurikirana ubukana buhebuje mu gukoresha ibikoresho bya karbide akenshi byatumaga habaho intege nke zikomeye: impande zoroshye, urwembe-ruto-ruto rukunze kwangirika mikorobe no kwambara byihuse, cyane cyane mu bikorwa bitarambiranye imitwaro iremereye mu bikoresho bikomeye nk'ibyuma bikomeye, superalloys, hamwe n'ibyuma. Uku gucika intege kwatumye kurangiza bidahuye, kongera imbaraga zo gukata, kunanirwa ibikoresho bidashyitse, hamwe nikintu kibabaje cyo "guca ibibyimba" - cyubatswe (BUE) aho ibikoresho byakazi bisudira ku gikoresho, bitesha agaciro imikorere nubuziranenge bwubuso.
Inzira nshya yatunganijwe neza ikemura iki kibazo. Kwimuka kurenga impande zoroshye cyangwa kuzenguruka gakondo, ubu buryo bwa tekinoroji yubudage burimo imiti igenzurwa cyane. Ihindura neza micro-geometrie yo gukata kurwego rwa sub-micron.
Ubumenyi bugenzurwa "Dulling":
Intego ya Micro-Bevel Kurema: Aho gusiga inkombe ya atomike ityaye (kandi ivunaguye), inzira irema ibintu bidasanzwe, bigabanutse cyane cyangwa radiyo kuruhande. Iyi micro-bevel yakozwe kugirango ibe nini bihagije kugirango ikureho intege nke, zikunda kuvunika.
Kurandura Micro-Inenge: Inzira icyarimwe yoroshya kandi ikuraho amakosa ya microscopique idasanzwe hamwe ningingo zitsindagurika zasigaye mubikorwa byo gusya, bigashyiraho agace k’inzibacyuho kitagira inenge inyuma yukuri.
Kuzamura Edge Ubunyangamugayo: Igisubizo ni impande zigumana ubukana budasanzwe bwo gukata ariko zikagira imbaraga ziyongera kuburyo bugaragara no kurwanya gukata no guhindagurika.
Imikorere yunguka kwisi nyayo:
Uru ruganda rwubatswe neza rusobanura inyungu zifatika kumaduka:
"Gukarisha & Byihuta" Gukata: Bitandukanye nubushishozi, impande ya passivasi yiboneye cyane kugabanya gukata. Mugukumira micro-chiping no gutangiza BUE, igikoresho gikomeza geometrie yateguwe nuburemere burebure cyane. Ibi bituma umuvuduko mwinshi wo gutunganya (Vc) hamwe nigipimo cyibiryo (f) udatanze ubunyangamugayo, kuzamura umusaruro.
Ikirenga Cyiza Kurangiza: Kurandura micro-chiping kandi yubatswe ni ngombwa kugirango ugere ku buso budasanzwe. Igikorwa gihamye, cyoroshye cyo gukata gitanga bores hamwe nigiciro cyo hasi ya Ra, akenshi ikuraho ibikorwa byanyuma. Umurage "Ubudage bwo gutunganya" umudage ushimangira uku gukurikirana ibintu byuzuye kandi bitunganijwe neza.
Kugabanya Ibibyimba Kugabanya (BUE): Mu koroshya inkombe no gukuraho ingingo zo guhangayika, passivation igabanya ibibanza bya nucleation aho ibikoresho byakazi bishobora gukurikiza. Ufatanije nigikorwa cyogukata cyoroshye no kugabanya guterana amagambo, ibi bigabanya cyane imiterere yimpande zubatswe, byemeza ko imiyoboro ihoraho hamwe nimbaraga zo gutema zihamye.
Ubuzima Bwagutse Bwubuzima: Imbaraga zongerewe imbaraga hamwe no kurwanya gukata no kwambara bisobanurwa muburyo bwo gukoresha ibikoresho birebire. Ibikoresho bikora buri gihe kubice byinshi mbere yo gusaba gusimburwa cyangwa kwisubiramo, kugabanya igihe cyo hasi hamwe nigiciro cyibikoresho kuri buri gice.
Kongera uburyo bwo kwizerwa: Kugabanya gukata kugabanuka no guhagarika BUE biganisha kumiterere yimashini iteganijwe, ihamye. Ibi bigabanya kunyeganyega, bitezimbere uburinganire, kandi bigabanya ibyago byibice byakuweho kubera kunanirwa ibikoresho cyangwa ubuziranenge bwubutaka.
Ingaruka zinganda no kuboneka:
Ikoranabuhanga ni ingirakamaro cyane cyane mu gusaba porogaramu zisanzwe mu kirere, powertrain yimodoka, gukora ibikoresho byubuvuzi, ninganda zingufu, aho kurambira ibyobo byimbitse, byuzuye mubikoresho bigoye ni ibintu bisanzwe. Ababikora bahanganye nubwiza bwuzuye, ibikoresho byubuzima bidahuye, cyangwa ibibazo byubatswe ni abakandida ba mbere bunguka.
