Imigaqo ye-laser annealing
I-Laser annealing iboniswa ngokusisiseko kwisehlo sokuphazamiseka kwefilimu ebhityileyo ngelixa inika isinyithi inkangeleko enemibala. Xa ukukhanya kubengezela kumphezulu womsebenzi ovaliweyo, kucandwa kube ngamaza amabini. Amaza ahlulwe ngokubonakalisa ngokwahlukileyo.
Umboniso wokuqala ubonwa xa umaleko weoksidi ongaphezulu ubethwa yimitha yokukhanya. Emva koko, ukubonakaliswa kwesibini kwenzeka xa ukukhanya okudlula kuluhlu lwe-oxidized kufikelela kwi-substrate engalungiswanga. Zombini imiboniso ineendlela zamaza ezingaphandle kwesigaba; ngaloo ndlela banobude bamaza ahlukeneyo. Amaza atshabalalisayo okanye ngokwakhayo aphazamisana nomnye ukuvelisa imibala ethile yomsebenzi. Ukuphazamiseka okwakhayo kunika izinto ezibonakalayo umbala walo oyintloko.
Iqhezu lokukhanya okudlulayo lifunxwa ngumaleko we-oxide. Ukukhanya okungaphezulu kuya kuthatyathwa ukuba umaleko ujiyile kwaye ungaphantsi ubonakaliswa ngaxeshanye. Ngenxa yoko, umphezulu wandisa ubumnyama bawo ngokunyuka kobunzima bomgangatho we-oxide. Kule meko, iiparamitha ezahlukeneyo ze-laser zilawulwa ukufumana imibala eyahlukeneyo emihle.
Isebenza njani i-laser annealing
I-Anealing yenziwa xa izixhobo laser annealing ekuhlaleni ifudumeza intsimbi ide ifikelele kwinqanaba lokunyibilika kwayo. Ulwakhiwo lwe-lattice lutshintsha ngexesha lenkqubo apho ukuveliswa kwe-oksidi kumphezulu we-workpiece kuboniswe kwinkalo yemibala eyahlukeneyo yokudibanisa. Imibala ibonakala malunga nama-200oC kuba zizinzile kwiqondo lobushushu.
Amaqondo obushushu aphezulu abuyisela iletisi kwimeko yayo eqhelekileyo. Kule meko, uphawu luyanyamalala; ngaloo ndlela, umphezulu ogqityiweyo uhlala ulondolozwe ngokupheleleyo. Emva kokuba inkqubo igqityiwe, izinto ziqala ukupholisa zibonisa uphawu olujoliswe kuyo. Ngokubanzi, ukumakishwa kwelaser kwenziwa kuphela zisinyithi ezitshintsha umbala xa ziphantsi kobushushu kunye neoksijini. Imizekelo yezi zinyithi yi-titanium kunye nentsimbi.
Ukusetyenziswa kwe-laser annealing
Apha ngezantsi kukho imizekelo yokusetyenziswa kwelaser annealing:
-I-electronics kunye nefiber optics
-I-Aerospace, izithuthi, kunye nemizi-mveliso yezokhuselo
– Amashishini amayeza okufakelwa kwezonyango
-Izixhobo zovavanyo ezifana laser lokumakisha iinkqubo nguToshiba
Ungawukhetha njani umatshini we-laser annealing
1. Izinto eziza kumakishwa
Izixhobo ezimakishwayo zimisela imodeli ye Umatshini wokumakisha we-laser ilungele iiprojekthi zomthengi. Oku kungenxa yokuba izixhobo ezahlukeneyo zineempawu ezahlukeneyo ze-optic. Umntu omnye umatshini laser ukusebenzisana nezinto ezahlukeneyo kuvelisa iziphumo ezahlukeneyo. Umzekelo, kukho umsebenzi owongezelelekileyo xa kuphawulwa imathiriyeli engafihliyo okanye eguquguqukayo xa kuthelekiswa naxa kusetyenziswa iilaser ukuphawula i-opaque workpieces. Esi sisiphumo sokukhanya okudlula kwizinto eziguquguqukayo ezisasaza ukukhanya kwaye ngaloo ndlela zenza kube nzima ukufakwa kwelaser. Kwakhona, umbala wezinto eziphathekayo uchaphazela ukumakisha kwe-laser. Izinto zokusebenza ezimnyama kulula ukuziphawula kuba zifunxa konke ukukhanya.

3. Ukuchaneka
Amashishini ahlukeneyo aneemfuno ezahlukeneyo zokuchaneka kwe-laser annealing. I-laser beam ingena kumphezulu wezinto eziphathekayo malunga ne-20 ukuya kwi-30 microns. Oku kubangela utshintsho oluncinci kwi-workpiece, echaphazela ukuchaneka nokuchaneka kwamanqaku. Inqanaba lokuchaneka limiselwa yimiba efana nobukhulu bebala le-beam kwizinto kunye nalapho indawo encinci ivelisa uphawu oluchanekileyo. Kwakhona, ulawulo lwe-thermal kunye nomgangatho we-optical system kufuneka uhlolwe ukuze uvelise iziphumo ezichanekileyo.
4. Isantya sokumakisha
Kukho umahluko kwisantya sokumakisha kwiimodeli ezininzi zezixhobo zokucoca ngelaser. Ziyahlukana nokuba ziimodeli eziphantsi okanye eziphezulu. Izinto ezichaphazela isantya sokumakisha umatshini ziquka umgangatho womzekelo, ubungakanani bokumakisha, kunye nohlobo lwezinto eziza kumakishwa. Ngokomzekelo, a Umatshini we-laser we-UV inesantya sokumakisha malunga ne-9000 mm/s. I-laser yomgangatho olungileyo ibonelela ngesantya esiphakathi sokumakisha imathiriyeli efana nesitshixo kwimizuzwana engama-30. Kwaye kukho iilaser ezikumgangatho ophezulu ezinokugqiba umsebenzi ofanayo ngaphantsi kwemizuzwana emi-5. Ukongeza, ukumakishwa kwe-laser kuthatha ixesha elingaphezulu kunokonakaliswa, kodwa akulimazi umphezulu wezinto kwaye kuvelisa amanqaku angabonakaliyo.
