Ibiranga by'ibanze bya Tekinoloji yo Gupfuka Imitako ya Laser
Ikoranabuhanga ryo gupfuka ifu hakoreshejwe laser, uburyo bugezweho bwo guhindura ubuso, bushobora gushyirwa mu byiciro bibiri by'ingenzi hakurikijwe uburyo bwo gutanga ifu: uburyo bwo gushyiraho ifu mbere y'uko ikoreshwa n'uburyo bwo gutanga ifu hakoreshejwe synchronous. Nubwo busangiye ibisubizo bimwe, uburyo bwo gutanga ifu hakoreshejwe synchronous buragaragara kandi bufite inyungu nyinshi zikomeye. Butuma habaho kugenzura imikorere idahindagurika, ari ingenzi ku musaruro munini w'inganda. Ubu buryo kandi bufite igipimo cyo hejuru cyo kwinjiza ingufu za laser, bunoza ikoreshwa ry'umutungo wa laser. Byongeye kandi, ibice byakozwe muri ubu buryo nta mwenge w'imbere urimo, bigatuma imiterere yabyo ikomera. Mu gihe cyo gukoresha icyuma gipfuka ifu hakoreshejwe synchronous, uburyo bwo gutanga ifu hakoreshejwe synchronous burabagirana cyane. Bunongera cyane ubushobozi bwo guhangana n'imivuniko y'urwego rwo gupfuka ifu kandi bugahamya ko ibice bikomeye bya ceramic bikwirakwira neza hose, byongera imikorere rusange y'ubuso bupfutse.
Gupfuka imirasire hakoreshejwe laser bigaragazwa n'imiterere yihariye. Ubwa mbere, bifite umuvuduko wo gukonjesha wihuta cyane, ukagera kuri 10⁶ K/s. Iyi nzira yo gukonjesha yihuta ituma habaho imiterere mito. Binafungura amarembo yo kurema ibice bishya bitashoboraga kugerwaho mu bihe bisanzwe, nk'imiterere isanzwe n'imiterere idahinduka. Ibi bintu bidasanzwe by'imiterere mito biha ibikoresho bipfuka imirasire myiza n'iy'umubiri.
Icya kabiri, igipimo cyo gushonga kw'ipamba mu gupfunyika kwa laser ubusanzwe kiri munsi ya 5%. Ibi bituma habaho isano ikomeye ya metallurgike cyangwa isano yo gukwirakwiza imbuga n'ubutaka. Mu guhindura neza ibipimo bya laser nk'imbaraga, umuvuduko wo gushakisha, n'igipimo cyo gutanga ifu, ipamba ryiza cyane rifite igipimo cyo gushonga gito rishobora kugerwaho. Uku kugenzura imiterere y'ipamba n'igipimo cyo gushonga bituma habaho guhinduranya kugira ngo huzuzwe ibisabwa byihariye.
Icya gatatu, gupfuka umuriro hakoreshejwe laser bisaba ubushyuhe buke, ibyo bigatuma habaho guhindagurika guke cyane. Iyo gupfuka umuriro hakoreshejwe imbaraga nyinshi, guhindagurika gushobora kugabanuka ku buryo bingana n’uko igice cyihanganira ubwiyongere bw’igice. Ibi bituma kiba cyiza mu gutunganya ibice bifatika hatabayeho gutakaza ubuziranenge bw’ibipimo.
Icya kane, nta mbogamizi zihari ku guhitamo ifu. Ibi bivuze ko bishoboka gushyira aloyi nyinshi ku buso bw'ibyuma bishongesha, bikongera uburyo ibikoresho bikoreshwamo no gukoresha laser cladding. Ubunini bw'urwego rwo gushongesha nabwo ni bwinshi cyane, hamwe n'ubugari bwa single-pass-feeding coating buva kuri mm 0.2 kugeza 2.0.
Gupfuka ibipfuka ni ikindi cyiza kigaragara cyo gupfuka ibipfuka bya laser. Bituma irangi rikoreshwa ku buryo bwihariye, bigabanura imyanda y'ibikoresho kandi bigatanga ikigereranyo cyiza cy'imikorere - ku giciro. Ubushobozi bwo kuboneza umuringoti wa laser butuma irangi rishyirwa ahantu hagoranye kugerwaho, bigatuma rikwirakwira ku bice bifite ishusho igoye. Amaherezo, inzira irahuye cyane n'imikorere y'ikoranabuhanga, ishimangira ireme n'umusaruro mwiza mu nganda.
