Ngenxa yeempawu zayo ezintle zomzimba nezekhemikhali, iimpawu zayo ezibalaseleyo zoomatshini, i-aluminium alloy isetyenziswa kakhulu kushishino lwe-half conductor kunye ne-microelectronics nakwezinye iindawo. Ngophuhliso lweemveliso zanamhlanje zoshishino ezijolise kwicala lamandla aphezulu, ukukhanya kunye nokusebenza okuphezulu, indlela yokusika i-aluminium alloy nge-laser nayo iphuhlisa ijolise kwicala lasekunene, ukusebenza okuphezulu kunye nokuguquguquka. Ukusika i-laser kuneenzuzo zomngxuma omncinci, indawo encinci echaphazeleka bubushushu, ukusebenza okuphezulu kunye nokungabikho koxinzelelo loomatshini, ngoko ke ibe yindlela ebalulekileyo yokulungisa ngokuchanekileyo i-aluminium alloy.
Ukusikwa kwe-aluminium alloy nge-laser ekhoyo ngokubanzi kusebenzisa indlela yokusika intloko kunye negesi encedisayo. Indlela yayo kukuba i-laser igxile ngaphakathi kwe-aluminium alloy, i-gasification enamandla aphezulu inyibilikisa i-aluminium alloy, kwaye umzimba wegesi encedisayo oxinzelelweyo ophezulu uqhushumbisa izinto ezinyibilikisiweyo. Le ndlela yokusika isebenzisa ikakhulu iintlobo ezimbini ze-laser enobude obumalunga ne-10640nm kunye ne-1064nm, zombini ezikwi-infrared wavelength range. Ekusikweni ngokuchanekileyo kweshiti ye-aluminium alloy kunye nokuchaneka kobukhulu bokusika benqanaba le-micron, ngenxa yendawo yayo enkulu kunye nendawo enkulu echaphazeleka bubushushu, kulula ukuvelisa i-slag exhonyiweyo kunye nee-micro-cracks kumda wokusika, ekugqibeleni ichaphazela ukuchaneka kunye nesiphumo sokusika.
Inkqubo yokusika nge-laser kunye nendlela ye-aluminium alloy kumzekelo inokuphumeza ukusika kwe-workpiece ngendlela engadibaniyo ngokusebenzisa ububanzi obuncinci be-pulse kunye nobude obufutshane be-laser beam, kwaye iphephe ukulahleka koxinzelelo lokunxibelelana kwe-workpiece ephathwa yindlela yoomatshini, kunye neengxaki ezifana nokuqhekeka okuncinci kunye ne-hanging slag ebangelwa yindlela yokusebenza eshushu kwinkqubo yokusika. I-workpiece eza kusikwa iqiniswe ngokuthe tye ngokusebenzisa isixhobo esithile, kwaye indawo yokusika ye-workpiece eza kusikwa ixhaswa ngasemva ngelixa indawo ye-slit igcinwe emoyeni, ukuze kuthintelwe isiphumo sokusika ukuba sonakaliswe luxinzelelo olubangelwa kukuwa ngexesha lokusika. Amanzi okupholisa ajikelezayo kwisixhobo setanki yamanzi asetyenziselwa ukupholisa iindawo zokusika ukunciphisa impembelelo yobushushu kwizinto ezijikelezileyo kunye nokuphucula umgangatho wokusika; Iindlela ezininzi zokusika zidityanisiwe ukwandisa ububanzi be-slit kunye nokuphucula ukusebenza kakuhle kokusika.
Ezi ndlela zingentla zezona ndlela zingcono zokusetyenziswa, kodwa ezi ndlela azithintelwanga ziindlela ezingentla. Naluphi na olunye utshintsho, utshintsho, utshintsho, indibaniselwano kunye nokulula okwenziwe phantsi komoya kunye nomgaqo ongaphambukiyo kwezi ndlela zingentla kufuneka zibe ziindlela zokutshintsha ezifanayo, ezibandakanyiweyo kumda wokukhusela wendlela yokusika i-laser ye-aluminium alloy.
