Ikoranabuhanga rigezweho ryo gusudira ni iki?
Iterambere rya siyansi n'ikoranabuhanga ryateje imbere iterambere rirambye mu ikoranabuhanga ryo gusudira, bituma habaho uburyo bushya bwo gusudira. Ikoranabuhanga rigezweho ryo gusudira ryerekeza ku buryo bugezweho bwo guhuza ibintu uretse uburyo busanzwe (nk'ubushuti bw'icyuma gikingira, gusudira arc munsi y'amazi, no gusudira arc metal isanzwe). Ivuka n'ubushakashatsi bw'ubu buryo bugezweho bwo gusudira bituruka ku guhuza ibyiciro bitandukanye by'ubumenyi. Ikoranabuhanga rigezweho ryo gusudira (urugero, gusudira hakoreshejwe ingufu nyinshi, gusudira laser-arc hybrid, gusudira vacuum diffusion, nagusudira roboti) byakoreshejwe mu ikoranabuhanga, ingufu, imodoka, iby’ikirere, inganda za kirimbuzi, n’izindi nzego. Bigira uruhare runini kandi rudasimburwa mu gusudira ibikoresho n’inyubako zidasanzwe, bigateza imbere iterambere ry’imibereho myiza n’ikoranabuhanga.
Gusudira ibikoresho bigezweho bifitanye isano rya hafi n'iterambere ry'ikoranabuhanga rigezweho kandi bifite imirimo idasanzwe kandi idasimburwa. Nyuma y'iterambere ryihuse mu kinyejana cya 20, ikoranabuhanga ryo gusudira, nk'ihuriro ry'ingenzi mu nganda za none, ryinjiye mu kinyejana cya 21 rifite sisitemu ikuze, iva mu gukora ibikoresho by'intoki ijya mu gukora ibikoresho by'ikoranabuhanga, bikora mu buryo bwikora, bishingiye ku makuru, kandi bifite ubwenge. Ibi bigaragaza igihe gishya mu bumenyi n'ubuhanga bwo gusudira.
(1) Gusudira hakoreshejwe laser-arc hybrid
Ikoranabuhanga rikoresha ingufu nyinshi rivugwa nk'ikoranabuhanga ritanga icyizere kurusha ayandi yose mu kinyejana cya 21, rikekwa ko "rizana impinduka zikomeye mu ikoranabuhanga ryo gutunganya no gukora ibikoresho," kandi ubu ni ryo shami ry’ikoranabuhanga rikura vuba kandi ryakoreweho ubushakashatsi cyane.
Iterambere ryaibikoresho byo gusudiraKu bijyanye n'ingufu nini bifite ibisobanuro bibiri: kimwe ni ukwiyongera kw'imbaraga z'ibikoresho, ikindi ni ukwagura ibice bisukwa n'ibikoresho. Bitewe n'ishoramari rinini ryakoreshejwe rimwe mu bikoresho bigezweho byo gusudira, cyane cyane ibikoresho byo gusudira hakoreshejwe laser na electron beam, kongera imbaraga, kunoza uburebure bw'uburyo bwo gusudira no kudahungabana bishobora kugabanya ikiguzi cyo gusudira, bigatuma byemerwa n'inganda. Kubwibyo, ikoranabuhanga ryo gusudira hakoreshejwe hybrid rishingiye kuri laser ryakuruye abantu benshi. Mu by'ukuri, gusudira hakoreshejwe laser-arc hybrid kwatangiye gutangwa mu myaka ya 1970, ariko ikoreshwa mu nganda rihamye ryagaragaye gusa mu myaka ya vuba aha, ahanini ryungukira ku iterambere ry'ikoranabuhanga rya laser n'ibikoresho byo gusudira hakoreshejwe arc, cyane cyane kunoza imbaraga za laser n'ikoranabuhanga ryo kugenzura arc. Laser-arc hybrid ahanini ikubiyemo guhuza laser na tungsten inert gas (TIG) arc, plasma arc, na arc active. Binyuze mu mikoranire hagati ya laser na arc, inenge za buri buryo bwo gusudira zishobora gukemurwa, bigatuma habaho ingaruka nziza zo kuvanga.
Gusudira imirasire ya laser-arc hybrid byongera cyane imikorere myiza yo gusudira, ahanini bishingiye ku ngaruka ebyiri: iya mbere, ubucucike bw'ingufu nyinshi butuma umuvuduko wo gusudira wiyongera kandi bigagabanya ubushyuhe bw'igikoresho; iya kabiri, ingaruka zo gushyira hamwe kw'ingufu zombi zikoreshwa mu gusudira. Iyo usuka icyuma, plasma ya laser iratuza imirasire; icyarimwe, imirasire yinjira mu mwobo w'ikidendezi cyashongeshejwe, bigagabanya igihombo cy'ingufu. Guhuza imirasire ya laser na TIG bishobora kongera umuvuduko wo gusudira cyane, hafi inshuro ebyiri z'umusuduro wa TIG. Kwangirika kwa electrode ya tungsten na byo biragabanuka cyane, byongera igihe cyo kuyikoresha; inguni y'umuyoboro nayo ishobora kugabanuka cyane, kandi agace k'umusuduro kangana n'ako gusudira imirasire ya laser. Ugereranyije no gusudira imirasire ya laser-single arc hybrid, gusudira imirasire ya laser-double arc hybrid byongera ubushyuhe bwo gusudira ku kigero cya 25% no kongera umuvuduko wo gusudira ku kigero cya 30%.
Ibyiza by'ingenzi byo gusudira hakoreshejwe laser-arc (cyangwa plasma arc) hybrid ni ukwihuta cyane mu gusudira no kwinjira mu bujyakuzimu. Bitewe no gushyushya arc, ubushyuhe bw'icyuma buriyongera, bigagabanya ubushobozi bwo kugarura urumuri mu cyuma, ndetse bikongera ubushobozi bwo kwinjiza urumuri. Ubu buryo bwageragejwe ku gusudira CO₂ laser ifite ingufu nke, ndetse no gusudira CO₂ laser ya 12kW na laser ya YAG ya 2kW ifite fibre optique, bishyiraho urufatiro rwo gusudira hybrid ya robotic laser-arc (cyangwa plasma arc). Mu myaka ya vuba aha, ikoranabuhanga ryo gusudira rya hybrid ryavutse kuri laser-arc hybrid ryageze ku iterambere rigaragara, kandi ikoreshwa ryaryo mu bice bigoye mu kirere, mu gisirikare, no mu zindi nzego ryitaweho cyane. Muri iki gihe, ikoranabuhanga ryo gusudira rya hybrid rihuza imirasire ifite ingufu nyinshi n'imirasire itandukanye ryabaye kimwe mu bintu bikunze kugaragara mu rwego rwo gusudira imirasire ifite ingufu nyinshi.
(2) Gusudira mu buryo bwo gukururanya ibintu
Friction Stir Welding (FSW) ni ikoranabuhanga ryo gusudira rifite patenti ryakozwe n'Ikigo cy'Ubwongereza gishinzwe gusudira (TWI) mu ntangiriro z'imyaka ya 1990. Rishobora gusudira ibyuma bidafite feri bigoye gusudira hakoreshejwe uburyo bwo gusudira buvanze.
Gusudira ibyuma bivanze bifite ibyiza nko guhuza ibintu byoroshye, gushyiramo uduce duto mu gice gisundiye, gukora neza mu munaniro, gukora neza mu gukurura no gupfunyika, nta nsinga zikenewe cyangwa imyuka irinda, nta rumuri rw'umurambararo, ndetse no kudatakaza imbaraga no guhindura ibintu nyuma yo gusudira. Byakoreshejwe mu nganda z'indege zo mu bihugu byateye imbere mu Burayi na Amerika, kandi byakoreshejwe neza mu gusudira imiyoboro y'umuvuduko w'inkuta za aluminiyumu ikora ku bushyuhe buke, birangiza igice cy'umuvuduko ugororotse w'imiyoboro y'insinga n'igice cy'umuvuduko ukikije imiyoboro y'insinga. Iri koranabuhanga ryakoreshejwe mu gushushanya imodoka nshya no gukoreshwa mu by'indege, gutwara abantu n'ibintu, inganda n'izindi nganda.
(3) Gusudira mu buryo bworoshye (Vacuum Diffusion)
Kugaragara kw'ibikoresho bigezweho bikomeza guteza imbogamizi nshya ku ikoranabuhanga ryo guhuza. Guhuza ibikoresho byinshi bishya, nka alloys zirinda ubushyuhe, ceramics zigezweho, intermetallic compounds, n'ibikoresho bivanze, cyane cyane guhuza ibikoresho bitandukanye, biragoye kugeraho hakoreshejwe uburyo busanzwe bwo guhuza, bityo habayeho guhuza ibintu bikomeye n'ubundi buryo. Urugero, ikoranabuhanga ryo guhuza ibintu bya superplastic ryakoreshejwe neza mu miterere y'indege ya titanium alloy honeycomb. Ceramics n'ibyuma bishobora guhuzwa no guhuza ibintu bishya; ikoreshwa ry'ikoranabuhanga ryo guhuza ibintu bishya mu gihe gito ryakemuye ibibazo byinshi bigoye byo guhuza ibintu bikomeye bitashoboraga gukemurwa nagusudira mu buryo bwo guhuzamu bihe byashize.
Guhuza ibintu bikomeye bishobora kugabanywamo ibyiciro bibiri. Kimwe ni uburyo bwo guhuza ibintu bufite ubushyuhe buke, umuvuduko mwinshi, n'igihe gito, ibyo bigatuma ubuso bw'ibikoresho bukorana hafi kandi agace k'imashini gacika binyuze mu guhindura imiterere ya pulasitiki. Guhindura imiterere ya pulasitiki ni cyo kintu cy'ingenzi mu gukora ingingo. Ubwo buryo bwo guhuza ibintu burimogusudira ku buryo bworoshye, gusudira ibisasu, gusudira igitutu gikonje, no gusudira igitutu gishyushye, ubusanzwe byitwa gusudira igitutu. Ubundi ni uburyo bwo guhuza hakoreshejwe ubushyuhe bwinshi, igitutu gito, kandi igihe kirekire, muri rusange bukorerwa mu kirere kirinda cyangwa mu cyuma gifunze. Ubu buryo bwo guhuza butanga gusa impinduka nke za pulasitiki, kandi gukwirakwiza hagati y’imirongo ni cyo kintu cy’ingenzi mu gukora urusobe rw’ingingo. Ubwo buryo bwo guhuza ahanini burimo gusudira igitutu, nko gusudira igitutu gifunze, gusudira igitutu gifunze mu buryo bwa transient liquid phase, gusudira igitutu gifunze mu buryo bwa isostatic, no gusudira superplastic forming-diffusion.
Uretse gukomeza kugaragara uburyo bugezweho bwo gusudira n'uburyo bushya (ibi byavuzwe haruguru ni bike gusa), urwego rw'imashini n'uburyo bwo gukora ibintu mu buryo butandukanye bwo gusudira rukomeje gutera imbere. Iterambere ry'ikoranabuhanga rya elegitoroniki, ikoranabuhanga ryo kumenya ibintu, mudasobwa, n'ikoranabuhanga ryo kugenzura byateje imbere cyane iterambere ry'icyiciro cyo gusudira, bituma uburyo bwo gusudira bugana ku buyobozi bw'ubwenge. By'umwihariko, ishyirwaho rinini rya robo zo gusudira ryanyuze mu buryo busanzwe bwo gusudira buhamye, ryafunguye uburyo bushya bwo gukora ibintu mu buryo bworoshye mu gusudira, kandi ritanga umwanya wagutse w'iterambere ry'ikoranabuhanga ryo gusudira. Gusudira byabaye uburyo bw'ingenzi bwo gutunganya ibintu mu nganda zigezweho. Byongeye kandi, hamwe n'iterambere rya siyansi n'ikoranabuhanga n'iterambere ry'imibereho myiza n'ubukungu, amashami yo gukoresha uburyo bugezweho bwo gusudira/guhuza azakomeza kwaguka.
(4) Gusudira hakoreshejwe ikoranabuhanga kandi hifashishijwe ubwenge
Gukoresha imashini n'ikoranabuhanga mu buryo bwikora ni uburyo bw'ingenzi bwo kunoza umusaruro wo gusudira, kwemeza ko umusaruro ufite ireme, no kunoza imiterere y'akazi. Gukora mu buryo bwikora mu gutunganya ubushuti ni icyerekezo cy'iterambere ry'ikoranabuhanga ryo gusudira mu gihe kizaza. Kunoza imikorere n'ubwiza bw'umusaruro wo gusudira bifite imbogamizi zimwe na zimwe ukurikije uburyo bwo gusudira. Uburyo bwo gusudira/guhuza nka electron beam welding, laser welding, na friction stir welding bifite ibisabwa bikomeye ku miterere y'imiyoboro n'ubwiza bw'iteraniro. Nyuma yo gusudira mu buryo bwikora, imiterere yose yo gusudira iba isukuye, isobanutse neza, kandi nziza, ihindura imikorere y'intoki mu mashami yo gusudira mu bihe byashize.
Nk'imwe mu bimenyetso by'ingenzi by'iterambere ry'ikoranabuhanga rigezweho mu nganda zigezweho mu ikoranabuhanga, robots zagize ingaruka zikomeye ku nzego zitandukanye z'inganda zigezweho mu ikoranabuhanga. Uburyo bugoye bwo gukora imashini zo gusudira hamwe n'ibisabwa bikomeye kugira ngo ireme ry'ubusoda rirusheho kuba ribi, hamwe n'urwego rw'ikoranabuhanga ryo gusudira rukunze kuba rubi ndetse n'imiterere y'akazi, bituma imashini zo gusudira zishobora kwikora no gushyira mu gaciro imashini zo gusudira zitabwaho by'umwihariko. Kuri ubu, 30% kugeza kuri 40% by'imashini zo gusudira ku isi yose zikoreshwa mu ikoranabuhanga ryo gusudira. Imashini zo gusudira zabanje gukoreshwa cyane cyane mu miyoboro yo gusudira mu nganda z'imodoka, kandi mu myaka ya vuba aha, zagiye ziyongera buhoro buhoro mu zindi nganda zikora.
Icyerekezo cya mbere cy'iteramberegusudira by'ubwengeni sisitemu yo kureba. Sisitemu zo kureba zakozwe ubu zishobora gutuma robo zihindura mu buryo bwikora inzira y'urumuri hakurikijwe imiterere yihariye mu gihe cyo gusudira, kandi zimwe zishobora guhindura ku gihe ibipimo by'imikorere hakurikijwe ingano y'umuyoboro.
