Inguquko ye-Solid -ye-State Bonding: Kutheni i-Diffusion Welding 'sesona sisombululo'
Kwinguquko yale mihla yombane, izithuthi zombane (ii-EVs), kunye nemizi-mveliso yegridi ehlakaniphile, ukuthembeka kothumelo oluphezulu{0} lwangoku lube ngundoqo wokhuseleko lwenkqubo. I-Copper Flexible Connectors ngamacandelo abalulekileyo ayilelwe ukufunxa ukungcangcazela koomatshini, ukuhlawulela ulungelelwaniso lofakelo olungalunganga, kunye nokubonelela{2}}iindlela zokuqhuba kakuhle. Inkqubo yokuvelisa esetyenziselwa ezi ziqhagamshelo iyalela ngokuthe ngqo isilingi yokusebenza kwemveliso yokugqibela. Phakathi kweetekhnoloji ezahlukeneyo zokujoyina,Ukusasazwa kweWeldingivelile "njengomgangatho wegolide" wokusebenza okuphezulu-kweziqhagamshelo zobhedu ezibhetyebhetye ngenxa yeempawu zayo eziqinileyo ezikhethekileyo{1}}zelizwe.
Imigaqo yobuGcisa: Ukusuka kwiAtomic Diffusion ukuya kwiMetallurgical Fusion
I-Diffusion Welding ingaphezulu lee kunenkqubo elula yokucinezela ngokwasemzimbeni; bubuxhakaxhaka obuchanekileyo obuchanekileyo-bubuchwephesha be-welding obuphunyelelwe ngefuthe le-synergistic yobushushu obuphezulu kunye noxinzelelo. Eyona ndlela ingundoqo ibandakanya ukuzisa umphezulu wobhedu ococekileyo kuqhagamshelwano olusondeleyo kumaqondo obushushu asuka kuma-60% ukuya kuma-80% wendawo yokunyibilika kwemathiriyeli (0.6T–0.8T). Kweli nqanaba, iiathom zobhedu zifumana amandla ashushu okwaneleyo ukoyisa izithintelo zamandla, ziqalisa ukusasazwa ngokulinganayo kunye nokufuduka ngaphaya kojongano.
Le nkqubo ikhatshwa yi-microscopic deformation yeplastiki kunye nohlengahlengiso lwemida yengqolowa. Ngokuhamba kwexesha, ujongano lonxibelelwano lokuqala luyanyamalala, endaweni yalo kukukhula okuziinkozo okuqhubekayo. Ekugqibeleni, ibhondi ye-metallurgical yenziwa kwinqanaba le-molecular, elifana nesakhiwo somzimba, ukubunjwa kweekhemikhali, kunye neempawu zombane kwisiseko sesinyithi. Oku kudityaniswa "kungenamthungo" sisizathu esisisiseko sokuba kutheni i-welding ye-diffusion igcina ukusebenza okungaqhelekanga phantsi kweemeko zokusebenza ezigqithisileyo.
IiNzululwazi eziPhambili ze-Diffusion Welding for Copper Connectors: Uhlalutyo lwexabiso
I-Diffusion welding ithandwa kakhulu kukwenziwa okuphezulu{0}}kakhulu ngenxa yokusebenza kwayo kakhulu ekuqhubeni kombane, ukuthembeka koomatshini, kunye nokuchaneka kokwenziwa kombane.
Incopho yokuQhutywa koMbane kunye noLawulo lweThermal
Ngenxa yokuba i-welding ye-diffusion ayithembeli kwizinto zokuzalisa (ezifana nesilivere ye-brazing foil okanye i-tin pastes), akukho maleko yesinyithi yangaphandle kwindawo edibeneyo. Oku kubangela ukuba kusondele{1}}ziro ukonyuka koxhathiso. Kwiindawo eziphakamileyo{{3} zangoku, olu dibaniso lwehomogeneous lunciphisa ngokubonakalayo amaqondo obushushu asekuhlaleni kwaye lucuthe ilahleko yamandla. Kwiinkqubo zamandla apho ukusebenza kakuhle kwamandla kubaluleke kakhulu, i-diffusion welding ayikhuphi nje uguqulo olusebenzayo kodwa yandisa ubomi bamacandelo ajikelezileyo e-elektroniki ngolawulo oluphezulu lobushushu.
Ukuthembeka okuKhethekileyo kweMechanical kunye nokuNxhathisa ukukhathala
Amalungu enziwe nge-diffusion welding afikelela kwi-100% yokomelela kwesiseko sesinyithi. Ukusukela ukuba inkqubo yenzeka kwindawo eqinileyo, Ubushushu{2}}INdawo echaphazelekayo incinci, igcina ukuguquguquka kwasekuqaleni kunye namandla okudinwa kweefoyile zobhedu. Kwiziqhagamshelo eziguqukayo ekufuneka rhoqo zinyamezele ukungcangcazela koomatshini okanye ukufuduswa kolwandiso lwe-thermal, ukusasazwa{4}} kwamalungu adityanisiweyo anika uzinzo olungenakuthelekiswa nanto. Ngaphaya koko, ukungabikho kojongano lwesinyithi olungafaniyo kuphelisa ngokupheleleyo umngcipheko wokonakala kwegalvanic, kuqinisekisa ukuthembeka kwexesha elide{6}}kwindawo efumileyo okanye ephezulu{7} yetyuwa.
Imveliso eluhlaza kunye - noLawulo lweJiyometri oluchanekileyo
Njengenkqubo yokuvelisa ecocekileyo, i-diffusion welding ayifuni ukuguquguquka, ukuphelisa ukukhutshwa komsi onobungozi, i-spatters, okanye izinto ezinobuthi kumthombo. Ukongeza, ngenxa yokuba imathiriyeli ayinyibiliki kwaye iqiniswe, i-macroscopic deformation ayinanto, ivumela ukuchaneka okuphezulu kakhulu kunye nokugqitywa komphezulu ogudileyo. Oku kuchanekileyo kuhlala kuphelisa imfuno yokusila okwesibini okanye ukucocwa kweekhemikhali, ukulungelelanisa ngokubonakalayo isithuba{2}} sokuhamba komsebenzi ngokuhambelana nemigangatho yangoku yokuvelisa eluhlaza.
Unyino kunye neMiceli mngeni yoShishino lwe-Diffusion Welding
Ngelixa i-welding ye-diffusion iphantse yagqibelela ngokwemigaqo yokusebenza, umqobo wayo ophezulu ekungeneni kunye neemfuno ezingqongqo zenkqubo ifuna indleko esengqiqweni{0}}urhwebo lorhwebo{1}}lususwe ngabenzi bezigqibo{2}}abenzi.
Utyalo-mali lokuqala oluPhezulu kunye neeNdleko zokuSebenza
I-welding yokusasazwa ifuna ukuchaneka okugqithisileyo kwezixhobo. -oomatshini bokusebenza abaphezulu babandakanya iinkqubo zokulawula uxinzelelo oluntsonkothileyo, -ukufudumeza okuphindaphindayo, okanye{3}}imeko-bume zevacuum eziphezulu, okwenza inkcitho enkulu ibe phezulu kakhulu kuneyokubrayiza kwemveli okanye izixhobo zokuwelda. Ngaphaya koko, izixhobo zesiko kunye nokufa ziyafuneka kwiinkcukacha ezahlukeneyo zekhonkco, ezinokuthi zithintele ubhetyebhetye kunye neendleko-ezisebenzayo kwibhetshi{6}}encinci, ephezulu{7}}kummandla oxubeneyo wemveliso.
UNyango lwaPhambi olungqongqo kunye noLawulo lokusiNgqongileyo
Inkqubo yokusabalalisa i-hypersensitive ukucoceka komphezulu. Nokuba umkhondo wemilinganiselo ye-oxide yesikali, ioyile, okanye iminwe kwifoyile yobhedu inokusebenza njengezithintelo ezibonakalayo ekusasazeni i-athomu, ekhokelela ekunciphiseni amandla ebhondi okanye ukuhanjiswa kwe-compromised. Ngenxa yoko, ukucocwa okungqongqo kweekhemikhali, ukupolisha ngoomatshini, okanye iiprothokholi zonyango lweplasma kufuneka ziphunyezwe. Oku kuthembela kunzima kumphezulu wemfezeko yongeza ukuntsokotha kumjikelo wemveliso kwaye kubeka iimfuno eziphezulu kucoceko -kwindlela yolawulo lokusingqongileyo.
Ukutyhubela imveliso kunye nemiqobo yeJiyometri
Xa kuthelekiswa -nemijikelo yesibini ye-ultrasonic welding, i-diffusion welding ifuna ukufudumeza okude, ukubamba, kunye namaxesha okupholisa ukuqinisekisa ukusasazwa kwe-athomu. Nangona ooshicilelo bale mihla bemizi-mveliso basebenzisa-uyilo lwezikhululo ezininzi ukwandisa amaxesha omjikelezo, imveliso isengaba ngumqobo kwimveliso enkulu-. Ukongeza, inkqubo okwangoku ifaneleke kakhulu kwiplani yamalungu emilenze. Ukuqinisekisa ukuhanjiswa koxinzelelo olufanayo kuzo zonke iijiyometri ezintsonkothileyo ze-3D kuhlala kungumngeni obalulekileyo wobugcisa kushishino.
