Ngenxa yezakhiwo zayo ezinhle zomzimba nezamakhemikhali, izakhiwo ezinhle kakhulu zemishini, i-aluminium alloy isetshenziswa kabanzi embonini ye-half conductor kanye ne-microelectronics kanye neminye imikhakha. Ngokuthuthuka kwemikhiqizo yezimboni yesimanje ebheke ekuqondeni kwamandla aphezulu, ukukhanya nokusebenza okuphezulu, indlela yokusika i-aluminium alloy nge-laser nayo iyathuthuka ibheke ekuqondeni kokunemba, ukusebenza kahle okuphezulu kanye nokuguquguquka. Ukusika i-laser kunezinzuzo zomngxunya omncane, indawo encane ethintekile ekushiseni, ukusebenza kahle okuphezulu kanye nokungabi nokucindezeleka kwemishini, ngakho-ke sekuyindlela ebalulekile yokulungisa i-aluminium alloy ngokunemba.
Ukusikwa kwe-aluminium alloy nge-laser okukhona ngokuvamile kusebenzisa indlela yokusika ikhanda kanye negesi eyisizayo. Indlela yayo iwukuthi i-laser igxile ngaphakathi kwe-aluminium alloy, i-gasification enamandla aphezulu incibilikisa i-aluminium alloy, kanti umzimba wegesi eyisizayo ocindezelekile kakhulu uphephula izinto ezincibilikisiwe. Le ndlela yokusika isebenzisa kakhulu izinhlobo ezimbili ze-laser enobude be-wavelength obungaba ngu-10640nm kanye no-1064nm, zombili ezingaphansi kobubanzi be-wavelength ye-infrared. Ekusikweni okunembile kweshidi le-aluminium alloy elinokunemba kosayizi wokusika wezinga le-micron, ngenxa yendawo yalo enkulu nendawo enkulu ethintekile ekushiseni, kulula ukukhiqiza i-slag elengayo kanye nemifantu emincane enqenqemeni yokusika, ekugcineni okuthinta ukunemba kanye nomphumela wokusika.
Uhlelo lokusika nge-laser kanye nendlela ye-aluminium alloy esibonelweni kungafeza ukunqunywa kwe-workpiece ngendlela engathintani ngokusebenzisa ububanzi obuncane be-pulse kanye nobude obufushane be-laser beam, futhi kugwenywe ukulahlekelwa ukucindezeleka kokuxhumana kwe-workpiece ephathwa ngendlela yemishini, kanye nezinkinga ezifana nokuqhekeka okuncane kanye ne-slag elengayo ebangelwa yindlela yokusebenza eshisayo enkambisweni yokusika. I-workpiece ezonqunywa iqiniswa ngokuvundlile ngokusebenzisa i-fixture ethile, futhi indawo yokusika ye-workpiece ezonqunywa isekelwa ngemuva ngenkathi indawo ye-slit igcinwa emoyeni, ukuze kuvinjelwe umphumela wokusika ukuthi wonakaliswe ukucindezeleka okubangelwa ukuwa ngesikhathi sokusika. Amanzi okupholisa ajikelezayo kudivayisi yethangi lamanzi asetshenziselwa ukupholisa izingxenye zokusika ukuze kuncishiswe ithonya lokushisa ezintweni ezizungezile futhi kuthuthukiswe ikhwalithi yokusika; Izindlela eziningi zokusika zihlanganiswa ukuze kwandiswe ububanzi be-slit futhi kuthuthukiswe ukusebenza kahle kokusika.
Izibonelo ezingenhla ziyizibonelo ezingcono, kodwa izibonelo azinqunyelwe yizibonelo ezingenhla. Noma yiziphi ezinye izinguquko, izinguquko, ukushintsha, ukuhlanganiswa kanye nokwenza lula okwenziwe ngaphansi kwesimo somoya kanye nesimiso esingaphambuki kulezi zibonelo ezingenhla kufanele kube izindlela zokufaka esikhundleni ezilinganayo, ezifakiwe kububanzi bokuvikela bendlela yokusika i-laser ye-aluminium alloy.
