Ababikora bahora bashaka gukora ibicuruzwa bikomeye, biramba, kandi byizewe, ndetse no mubice byimodoka nindege.Muri uku gukurikirana, bakunze kuzamura no gusimbuza sisitemu yibikoresho hamwe n'ubucucike buke, ubushyuhe bwiza hamwe no kurwanya ruswa.Ibi biha ababikora ikirenge cyiza ku isoko.
Mubyukuri, ibyo ni kimwe cya kabiri cyinkuru.
Ndetse imbaraga zikomeye zifatika nizishobora kugereranywa kubyerekeye imbaraga zicuruzwa, kuramba, no kwizerwa.
Guhinduranya ibikoresho bishaje kubikomeye birashobora kuba intangiriro nziza, ariko kandi birasaba inzira ziterambere ziterambere zishingira kumasuku meza kandi meza kugirango isukure neza.Ibyuma nka aluminiyumu n'ibikoresho bigezweho nka karubone fibre polymer yibigize, akenshi bikoreshwa mubikorwa byo gutwara ibinyabiziga no mu kirere, bisaba guhuza kugabanya ibiro - iyo bifatishije ibyuma, uburemere bwongewe kumiterere - no gukora ingingo zizewe.
Ubuhanga gakondo bwo kurangiza aluminiyumu burimo umucanga, guhanagura umusemburo, ugakurikirwa no gusya (ukoresheje pisine) cyangwa anodizing.Guhuza gufunga bifungura umuryango wibikorwa byinshi byikora kubisanzwe birangira bidahuye.
Anodizing irasanzwe mubikorwa byindege aho iyi myiteguro ihenze kandi ikomeye cyane ikoreshwa muguhuza ibisobanuro bikomeye.Imiterere ihindagurika yumusenyi hamwe nubuhanga bwo gukuramo intoki byerekana neza ko inzira igenzurwa neza.
Gukuraho lazeri cyangwa gukuraho laser byuzuza iki cyuho nkuburyo busobanutse neza, butangiza ibidukikije, bwikora kandi bunoze bwo kuvura ibyuma hamwe nuburinganire kugirango bisukure.Ubwoko bwanduye buboneka hejuru yibi bikoresho bivanwaho byoroshye no gutunganya laser.
Kuberako isuku ya laser ikomeye cyane, nibyingenzi kumenya neza uko igira ingaruka hejuru yawe.Itandukaniro riri hagati yubuso bufashwe neza nubuso butarengerwa cyangwa burenze urugero burashobora kugorana kubisuzuma.Hamwe na tekinoroji yo kugenzura ikorana buhanga kandi yunvikana nkibikorwa bya lazeri ubwayo, abayikora barashobora kwizera ko ibyuma byabo hamwe nibintu byose byiteguye guhuza.
Laser ikurikira iraguha intangiriro irambuye kumpamvu zo guhitamo isuku ya laser.
1 -Isuku rya Laser ni iki?
Ubuvuzi bwa Laser nubuhanga busobanutse neza, bwogusukura ubushyuhe bukora mugukuraho (ablation) uduce duto twubuso bwibintu binyuze mumurongo wibanze, akenshi usunikwa, urumuri rwa laser.Lazeri irasa hejuru kugirango ikureho atome kandi irashobora gukoreshwa mugucukura umwobo muto cyane, umwobo wimbitse ukoresheje ibikoresho bikomeye, bikabyara firime yoroheje cyangwa nanoparticles hejuru.
Ubu buryo bwo gukora isuku burakorwa neza kubera ubushobozi bwabwo bwo kwibasira ibice bito byanduye nibisigara.Ubuso bwa aluminiyumu burimo okiside hamwe namavuta yo kwisiga yangiza ifatanyirizo hamwe nibigize byinshi bigumana imyanda isigara hamwe nibindi byanduza silicone bidashobora gukora imiti ikomeye ya chimique.
Iyo igiti gishyizwe hejuru hamwe nimwe muribisigisigi bihari bizagerageza kwifashisha mumavuta na silicone kumurongo muto wa molekile yibikoresho.Iyi nkunga irakomeye cyane kandi byanze bikunze izananirwa haba mugihe cyibizamini cyangwa mugihe cyo gukoresha ibicuruzwa.Iyo ingingo zivunitse mugihe ubuso hamwe nugufata cyangwa gutwikira bihura ibi byitwa kunanirwa kwimbere.Kunanirwa gufatana mugihe cyo gupimisha lap ni mugihe ikiruhuko kibaye muri adhesive ubwayo.Ibi byerekana isano ikomeye cyane hamwe nuburyo bwateranijwe bushobora kwihangana kandi burambye.
Kunanirwa gufatanyiriza hamwe kwicyitegererezo cyakorewe lazeri yerekana ibifatika kumpande zombi zibikoresho bihujwe.
Kunanirwa hagati yibi byitegererezo bitavuwe byerekana ko ibifatika byafashe gusa kuruhande rumwe bikarekura rwose kurundi.
Iyo ufite kunanirwa guhuriza hamwe, uba ufite isano ihuza intera itareka ubusa.Ubuvuzi bwo hejuru bugamije guhindura ubuso kugirango ukureho umwanda kandi ukore cyangwa uhishure ubuso buzashobora guhuza imiti hamwe nudusanduku twumuti urambye kandi wizewe.
2- Nigute Wamenya Niba Ubuso Bwawe bwa Laser Bwiteguye Kwihuza
Ibipimo byerekana impande zose, nkibyavuzwe mu mpapuro za IJAA zikoreshwa mu gusobanukirwa no gutesha agaciro imiti ivura amasaha y'ikirenga, ni inzira nziza cyane yo kugenzura no kugenzura uburyo bwo gukora laser.
Gupima impande zifatika byunvikana kumpinduka ya molekulari igaragara hejuru yubutaka bwa lazeri.Igitonyanga cyamazi gishyizwe hejuru kizamuka cyangwa kigabanuke ugereranije nubunini bwa microscopique yanduye hejuru.Ibipimo bifatika byerekana ibimenyetso simusiga byerekana ko bifatanye kandi birashobora gutanga ibisobanuro no kugaragara muburyo imbaraga zokuvura zihuye nogukenera ibikoresho.
Ibipimo byerekana impande zifitanye isano neza nimpinduka murwego rwanduye zafashwe nuburyo bwa spekitroscopi.Ibipimo byinshi byuzuye byanduye hejuru yubutaka bikorwa nibikoresho bidashoboka ko ababikora babigura kandi ntibishobora gukoreshwa mubice nyabyo byakozwe uko byagenda kose.
Ibipimo bifatika bishobora gukorwa ako kanya mbere na nyuma yo kuvurwa kumurongo wibyakozwe hamweimfashanyigishocyangwaibikoresho byo gupima byikora.Nkuko isuku ya laser isimbuza uburyo bwo gutegura hejuru yubusa bitewe nuburyo bukenewe bwo gukora ibintu byinshi cyane, bikozwe neza cyane, gupima ingero zifatika nabyo bituma ibizamini byujuje ubuziranenge kandi bidakwiye nka wino ya dyne hamwe nibizamini byo kumena amazi bitagikoreshwa.
Imbaraga zipima imikorere isuzuma gusa icyitegererezo cyibikoresho bitunganywa, ukongeraho igipimo cyo gusiba kandi ntutange ibimenyetso byerekana uburyo bwo gushiraho ubumwe bukomeye.Inguni zandikirwa, iyo zikoreshejwe mumurongo wibyakozwe zirashobora kwerekana neza aho inzira isaba guhindagurika, kandi irashobora gutanga ubushishozi kubikenewe guhindurwa no kurwego.
3- Kuki Ukoresha Gusukura Laser?
Habayeho ubushakashatsi bwinshi bukomeye kuburyo uburyo bwo kuvura laser butunganya neza.Kurugero,urupapuro rwasohotse mu kinyamakuru cya Adhesionyakoze ubushakashatsi kungene imbaraga zifatanije zongerwaho nogusukura laser bitandukanye nuburyo gakondo.
“Ibisubizo by'ubushakashatsi byerekana ko ubuvuzi bwa lazeri bwa preadhesion bwateje imbere cyane imbaraga zo gukata kwa aluminiyumu yahinduwe na epoxy ihujwe ugereranije na substrate itavuwe kandi idakoreshwa.Ibisubizo byiza byabonetse hakoreshejwe ingufu za laser zingana na 0.2 J / Pulse / cm2 aho imbaraga zo gukata lap imwe zazamutseho 600-700% ugereranije n’izitwa Al alloy itavuwe, naho 40% ugereranije na acide chromic anodizing pretreatment.
Uburyo bwo kunanirwa bwahindutse buva ku gufatana hamwe no guhuza uko umubare wa laser pulses wiyongereye mugihe cyo kuvura.Ikintu cya nyuma cyahujwe n’imihindagurikire y’imiterere nkuko byagaragajwe na microscopi ya electron, no guhindura imiti nkuko byagaragajwe na Auger na infragre spekitroscopi. ”
Iyindi ngaruka ishimishije yo gukuraho laser nimbaraga ifite yo gukora ubuso butangirika mugihe.
Amahirweyakoze imirimo ikomeye ireba uburyo isuku ya laser ikorana nubuso muburyo butangaje.Kuvura lazeri ya aluminiyumu ikora utubuto duto hejuru yubushonga kandi hafi icyarimwe igakomera mugice gito cya kirisiti hejuru yubutaka ndetse ikaba ishobora no kwangirika cyane kuruta aluminiyumu ubwayo.
Urebye ku mbonerahamwe ikurikira, irerekana itandukaniro riri hagati yimbaraga zogosha zumubano ukoresheje aluminium yavuwe na laser na aluminium yavuwe mumiti.Igihe kirenze, nkuko ubuso bwagiye bugaragaramo ibidukikije bitose, ubushobozi bwubutaka bwavuwe na chimique bwo guhuza neza buragabanuka cyane kuko ubuhehere butangira kwangirika hejuru, mugihe hejuru ya lazeri yatunganijwe igumana imbaraga zo kwangirika nyuma yicyumweru kiboneka.
