Ubuchwepheshe bokuhlanza nge-laserisetshenziswa kakhulu ekwelapheni ubuso bomzimba wendiza embonini yezindiza. Lapho kulungiswa futhi kugcinwa indiza, kuyadingeka ukususa upende omdala ebusweni ukuze kufakwe i-oyili entsha yokuqhumisa isihlabathi noma i-steel brush sanding kanye nezinye izindlela zendabuko zokufutha.ukuhlanza indawoifilimu yokupenda.
Emhlabeni,izinhlelo zokuhlanza nge-lasersekuyisikhathi eside isetshenziswa embonini yezindiza. Ubuso bendiza budinga ukupendwa kabusha ngemva kwesikhathi esithile, kodwa upende omdala wokuqala udinga ukususwa ngokuphelele ngaphambi kokupenda. Indlela yendabuko yokususa upende ngomshini kulula ukulimaza ubuso bensimbi bendiza, okuletha izingozi ezifihliwe endizeni ephephile. Ngokusebenzisa izinhlelo eziningi zokuhlanza nge-laser, upende ungasuswa ngokuphelele kwi-A320 Airbus zingakapheli izinsuku ezimbili ngaphandle kokulimaza ubuso bensimbi.
Isimiso somzimba sokuhlanza nge-laser ekuhlanzeni ubuso bendiza:
1. Ugongolo olukhishwa yi-laser lumuncwa ungqimba lokungcola olusebusweni oluzophathwa.
2. Ukumuncwa kwamandla amakhulu kwakha i-plasma ekhula ngokushesha (igesi engazinzile ene-ionized kakhulu), ekhiqiza igagasi lokushaqeka.
3. Igagasi lokushaqeka liphula ukungcola kube yizicucu bese liyaliwa.
4. Ububanzi be-pulse yokukhanya kumele bube bufushane ngokwanele ukuze kugwenywe ukwakheka kokushisa okungalimaza indawo ephathwayo.
5. Ukuhlolwa kubonisa ukuthi uma kukhona i-oxide ebusweni bensimbi, i-plasma ikhiqizwa ebusweni bensimbi.
Ukuhlolwa kokususa upende nge-laser (ukuhlanza nge-laser) ezikhumbeni zezindiza kwenziwa nge-laser fluences ka-2–6 J/cmexp. Ngemva kokuhlolwa kokuhlaziywa kwe-SEM kanye ne-EDS, imingcele yenqubo yokususa upende nge-laser engcono kakhulu ingu-5 J/cmexp. Ukuphepha kwendiza kubaluleke kakhulu, futhi akukho ukulahlekelwa ngengozi okuvunyelwe. Ngakho-ke, uma ubuchwepheshe bokususa upende nge-laser buzosetshenziswa kabanzi ekunakekelweni kwendiza, ukuhlanzwa kwendiza okungeyona ingozi kumele kufezwe.
Ngaphansi kwezimo ezahlukene zobuningi bamandla e-laser, izakhiwo zokungqubuzana nokuguguleka kwemigodi ye-rivet yesikhumba sendiza ngemva kokuhlanza zafundwa yinqubo yokuhlanza nge-laser, futhi izakhiwo zokungqubuzana nokuguguleka kwezinye izingxenye esikhumbeni zahlolwa. Ukuqhathaniswa kwenziwa namasampula ngemva kokugaya ngomshini nokuhlanzwa nge-laser. Imiphumela ibonise ukuthi ukuhlanzwa nge-laser akuzange kunciphise izakhiwo zokungqubuzana nokuguguleka kwanoma iyiphi ingxenye ebusweni besikhumba sendiza.
Ukucindezeleka okusele, ubulukhuni obuncane kanye nokusebenza kokugqwala kwendawo yesikhumba sendiza ngemuva kokuhlanzwa nge-laser kuhlolwe. Uma kuqhathaniswa nokugaya ngomshini kanye nokuhlanzwa nge-laser, imiphumela ikhombisa ukuthi ukuhlanzwa nge-laser akunciphisi ubulukhuni obuncane kanye nokumelana nokugqwala kwendawo yesikhumba sendiza. Kodwa-ke, ngemva kokuhlanzwa nge-laser, indawo yesikhumba sendiza izokhiqiza ukuguqulwa kwepulasitiki, okuyinkinga edinga ukunakwa okukhethekile lapho kusetshenziswa ubuchwepheshe bokuhlanza nge-laser ukwelapha indawo yesikhumba sendiza.
Ngesikhathi sokulungiswa kwendiza. Upende ophezu kwezindiza kumele ususwe, futhi isikhumba sezindiza kumele sihlolwe ukuthi asikwazi ukugqwala yini kanye nokuqhekeka kokukhathala ukuze kugwenywe izingozi zokundiza. Ngakho-ke, enkambisweni yokususa ngokucophelela upende ophezu kwesikhumba sendiza, kubalulekile ukunaka ngokukhethekile ukuthi inqubo yokususa upende kumele iqinisekise ukuthi i-substrate ayonakaliswa.
Izinqubo zokususa upende zendabuko zifaka phakathi ukuhlanzwa kwemishini, ukuhlanzwa kwe-ultrasonic, kanye nokuhlanzwa kwamakhemikhali. Nakuba ubuchwepheshe bokuhlanza obungenhla buwubuchwepheshe bokuhlanza obuvuthiwe, kusenezinselelo eziningi. Isibonelo, indlela yokuhlanza yokugaya ngomshini kulula kakhulu ukulimaza izinto eziyisisekelo, indlela yokuhlanza ngamakhemikhali izongcolisa imvelo, kanti indlela yokuhlanza nge-ultrasonic inqunyelwe usayizi wento yokusebenza, futhi akulula ukuhlanza izingxenye ezinkulu.
Eminyakeni yamuva nje, ngentuthuko esheshayo yobuchwepheshe be-laser, ubuchwepheshe bokuhlanza nge-laser bube ubuchwepheshe bokuhlanza obuzenzakalelayo, obucacile, futhi obushibhile. Ubuchwepheshe bokuhlanza nge-laser busetshenziswe kabanzi ekususeni upende nokugqwala, ukuhlanza isikhunta samasondo, ukuvikela izinsalela zamasiko, ukuhlanzwa kwe-nuclear, njll.
Uma ufuna ukufunda kabanzi ngokuhlanzwa nge-laser, noma ufuna ukuthenga umshini wokuhlanza nge-laser ongcono kakhulu kuwe, sicela ushiye umlayezo kuwebhusayithi yethu bese usithumelela i-imeyili ngqo!
