Kwimimandla ekhula ngokukhawuleza yeemodyuli zebhetri yemoto yamandla amatsha, iinkqubo zokugcina amandla e-photovoltaic, kunye ne-ultra{{0}ukuhanjiswa kwamandla ombane aphezulu,I-Polymer Diffusion Welding(esoloko ekubhekiselwa kuyo ngokulula njenge-Diffusion Welding kulo mxholo) iye yaba bubuchwephesha obubalulekileyo bokuphumeza i-molecular{0}}level bonding kubhedu kunye nefoyile ye-aluminiyam yeebhasi eziguquguqukayo. Le nkqubo isebenzisa ubushushu obuphezulu kunye noxinzelelo ukukhuthaza i-atomic inter{2}}ukusasazwa, ukwenza amajoyinti anokunganyangeki okuphantsi kakhulu kombane kunye namandla omatshini aphezulu.
Nangona kunjalo, "Ukunqongophala kweFusion" (LOF){0}}apho i-weld interface ingabotshwanga ngokwaneleyo{1}}yingxaki eqhelekileyo yobugcisa kubavelisi abaninzi. Esi siphene asonyusi nje ukuxhathisa kunye nokuveliswa kobushushu kwisinxibelelanisi kodwa kunokukhokelela ekusilelani phantsi kokungcangcazela, okunokubanga iingozi ezimandundu zenkqubo yamandla. Eli nqaku libonelela ngo{4}}uhlalutyo olunzulu lwezizathu ze-LOF kwaye libonelela ngeendlela eziqikelelweyo, zobuchule obusebenzayo.
-kuhlalutyo olunzulu: Kutheni i-Diffusion yakho ye-Weld inengxaki "kukunqongophala kwe-Fusion"?
Undoqo we-welding yokusasazwa uxhomekeke kumandla obushushu kunye noxinzelelo lomatshini ukuzisa imiphezulu emibini kuluhlu lomtsalane weathom. Ukunqongophala kweFusion ngokuqhelekileyo kwenzeka xa "igalelo lamandla" okanye "uqhagamshelwano lomzimba" ngexesha lenkqubo ye-welding ingaphumeleli ukuhlangabezana nomda obalulekileyo.
1. Ukungalingani kwe-Energy Input: "I-Weakest Link" yoBubushushu kunye nexesha
Ubushushu be-Welding ngoyena mqhubi we-atom yokusasazwa. Ngokuqhelekileyo, ubushushu be-welding ye-diffusion kufuneka bubekwe phakathi kwe-0.5 kunye ne-0.8 amaxesha e-absolute melting point ($ T_m $) yezinto ezisisiseko (kwi-Kelvin). Ukuba iqondo lobushushu libekwe phantsi kakhulu, amandla e-atomic kinetic ayonelanga ukoyisa umqobo wamandla angaphakathi.
Ngaphaya koko, i-thermal conduction lag ngoyena nobangela we-LOF kwiindawo ezishinyeneyo zokusebenza. Umzekelo, xa udibanisa ibhasi eshinyeneyo eyenziwe ngamaleko angama-100 efoyile yobhedu eyi-0.1mm, ukuba ixesha lokuwelda lifutshane kakhulu, ubushushu bunokungena kuphela kumaleko angaphandle. Oku kubangela ukuba ummandla ongundoqo usilele ukufikelela kwiqondo lobushushu elifunekayo, i-classic "ephekwe kakhulu ngaphandle, engavuthwanga ngaphakathi" imeko.
2. Izithintelo zoMzimba: Iindonga ezingabonakaliyo zeeFilimu ze-Oxide kunye ne-Machining Precision
Ngelixa i-welding ye-diffusion kwindawo yomoya, isebenzisa indlela yayo yokufudumeza ekhethekileyo, icinezela i-oxidation enzima, iifilimu ze-oxide ezikhoyo kwizinto ezibonakalayo (ezifana ne-$ Al_2O_3 $ kwi-aluminium foil) zineendawo eziphezulu zokunyibilika. Ukuba uxinzelelo alunelanga ukutyumza le filimu kwiqondo lokushisa eliphezulu, lisebenza njengomqobo wokukhusela, ukuthintela ukungenelela kwe-molecular. Ngaxeshanye, ukuba umcaba womphezulu oza kudityaniswa umbi (uburhabaxa obudlula i-0.1mm), eyona ndawo yoqhagamshelwano iya kuba ncinane kakhulu kunommandla wegama, okukhokelela kwi-microscopic voids kwindawo{5}}engadibananga.
Izisombululo eziSebenzayo: IiNdlela eziHlanu - zeNdlela yokuSebenzisa ukuphelisa iziphene zeWelding
Ukujongana nomba weLOF, iinkampani akufuneki zithembele ekwandiseni iiparamitha ngokumfameka koko ziseke inkqubo yenzululwazi, evaliweyo yokuphucula iluphu.
1. Ulawulo lobushushu oluchanekileyo: Ukuseka iMathiriyeli{1}}Ekhethekileyo "iTemperature Matrix"
Izixhobo ezahlukeneyo zinobuntununtunu bobushushu obahlukeneyo. Xa ulungelelanisa i-welder yokusasazwa, kuyacetyiswa ukuba ulandele le migangatho ibaliweyo yokwenziwa kwezigaba:
| Imeko yesicelo | Temp ecetyiswayo. Uluhlu ($^\\circ$C) | Uluhlu loxinzelelo (MPa) | Ingqiqo yeNkqubo engundoqo |
| I-Aluminiyam yeFoil Flex Busbar (0.1mm x 50 umaleko) | 480 - 540 | 5 - 8 | Gxininisa ekunyukeni ngokukhawuleza kobushushu ukunciphisa i-oxidation. |
| I-Copper Foil Flex Busbar (0.1mm x 100 iileya) | 550 - 620 | 10 - 15 | Ifuna inqanaba lokufudumala ukuze kuqinisekiswe ukungena okungundoqo. |
| Ubhedu{0}}I-Aluminiyam Engafaniyo Ukujoyina | 500 - 580 | 8 - 12 | Ukulawula ngokungqongqo ixesha lokuthintela ukubunjwa kwe-brittle intermetallic compounds. |
2. Ulawulo loxinzelelo: I-Physical Prerequisite yoQhagamshelwano lweMolekyuli
Uxinzelelo alusetyenziswanga kuphela ukucinezela izixhobo zokusebenza kodwa, okona kubaluleke kakhulu, ukuphembelela ukuguqulwa kweplastiki encinci, ukuqinisekisa unxibelelwano olusondeleyo phakathi komphezulu. Ukuba i-LOF yendawo iyenzeka, ukuhambelana kwee-dies (molds) kufuneka kuhlolwe. Kuyacetyiswa ukuba kusetyenziswe ifilim yoxinzelelo{2}}enovakalelo ukuvavanya usasazo loxinzelelo, uqinisekisa ukuba ngokupheleleyo-ukuguquguquka koxinzelelo lwenqwelomoya kulawulwa ngaphakathi kwe $\\pm 10%$. Ukwandisa uxinzelelo ukuya kwi-12-15 MPa kunokuphucula kakhulu i-LOF ebangelwa ukungonelanga kwendawo ethe tyaba, kodwa kufuneka kuthathelwe ingqalelo ukuthintela i-extrusion deformation egqithisileyo kumaphethelo omsebenzi.
3. Ukucocwa koMphezulu: IiNkqubo zokuCoca ngokuNzulu ngaphaya kokuSula okuLula
Kwi{0}imfuno eziphezulu zeendawo zokugcina amandla, ukosula utywala ngokulula kunokungonelanga ukususa{1}}i-oyile ehleliyo kunye negrisi. Kunconywa ukuba uqalise i-acid pickling okanye iinkqubo zokucoca i-plasma ukususa iileyile ze-oxide kunye nobukhulu obudlula i-10nm. Idatha yovavanyo ibonisa ukuba ii-workpieces eziphantsi kokucoca nzulu zinokufikelela ukonyuka kwamandla okucheba ngaphezulu kwe-20% phantsi kweeparamitha ze-welding ezifanayo.
Izifundo eziJolisiweyo: Izicelo eziDidifferent in the New Energy and Power Industries
1. I-Aluminiyam yeFoil Flex Busbars yeebhetri ze-EV: Phantsi{1}}Uxinzelelo, uKhawuleza{2}}Iqhinga le-Weld
Kwiimodyuli zebhetri ze-EV, i-aluminium foil ichaphazeleka kakhulu kwi-oxidation kwaye inendawo ephantsi yokunyibilika. Isitshixo sokusombulula i-LOF sisantya. Ngokwandisa isantya sokuphendula amandla we-welder, inkqubo yokusabalalisa igqityiwe ngaphambi kokuba ifilimu ye-oxide ijiye kakhulu. Isicwangciso soxinzelelo oluphantsi (5-7 MPa) kunye nexesha elifutshane kakhulu (imizuzwana ye-5-15) ngokuqhelekileyo isetyenziswa.

Iibhasi zamandla zingqindilili kwaye zichitha ubushushu ngokukhawuleza. Isitshixo sokusombulula i-LOF kukungena. Imowudi -yenqanaba lokufudumeza iyacetyiswa: okokuqala, tshisa kumandla asezantsi ukuya kwi $300 ^\\circ$C kwaye ubambe imizuzwana engama-20 ukunciphisa umahluko wobushushu wangaphakathi/wangaphandle. Emva koko, ngokukhawuleza unyuke ukuya kubushushu be-welding, udityaniswa noxinzelelo oluphezulu lwe-15 MPa ngexesha lokubamba, ukuqinisekisa ukudityaniswa okupheleleyo kwawo wonke umaleko wefoyile yobhedu.
Ukuthenga kunye nokuKhetha iNgcebiso: Ungawukhetha njani umatshini othembekileyo we-Diffusion Welding
Xa ukhetha okanye uthenga umatshini we-welding we-diffusion, abasebenzisi kufuneka bagxininise kwezi zalathisi zobugcisa zilandelayo ukunciphisa umngcipheko we-LOF kwimbono ye-hardware:
- Okuvaliweyo-Ukubek'esweni kweLoop yeNkqubo yoLawulo: Ngaba isixhobo sibonakalisa{1}}ixesha lokwenyani{2}}lokubeka iliso lokufuduswa? Ukukwazi ukurekhoda elona -ixesha loxinzelelo lwexabiso ngexesha le-welding sisalathisi esibalulekileyo sokuvavanya ukungena kwe-weld.
- Ukufudumeza okufanayo: Buza malunga nokuhanjiswa kweqondo lokushisa kwekhoyili ye-induction okanye ipleyiti yokumelana nokufudumeza. Umatshini{1}ophezulu womgangatho kufuneka uqinisekise umahluko wobushushu kwindawo yonke yokusebenza ngaphakathi kwe $\\pm 5^\\circ$C.
- Non-iVacuum Anti{1}}Itekhnoloji ye-Oxidation: Phanda ukuba ngaba isixhobo sibonelela ngokhuseleko lwerhasi engasebenziyo yasekuhlaleni okanye uxinizelelo olukhethekileyo lokuchasa{2}}izakhiwo zokukhupha i-oxidation. Oku kubalulekile ekusombululeni imiba ye-LOF kwi-aluminiyam ye-alloy welding ngaphakathi kwendawo yomoya.
Ukuqukumbela
Ukusombulula ukunqongophala kwe-Fusion kwi-welding ye-diffusion ingumbandela wokulinganisa ngokuthe ngqo ubushushu, uxinzelelo, ixesha kunye nomgangatho womphezulu. Ngokuseka imathiriyeli-ethe ngqo yobushushu bematrix, ukukhulisa ukuhambelana kweefa, kunye nokuphumeza ukucocwa komphezulu onzulu, iinkampani zinokususa ngempumelelo iingozi zokuwelda kunye nokuphucula ukukhuphisana kweemveliso zazo kumandla amatsha kunye neemarike zamandla. Xa ukhetha izixhobo, beka phambili imifuziselo ngokujongwa kwedatha kunye -nolawulo oluchanekileyo lwezakhono zokulawula ubushushu, njengoko oku kuya kubeka isiseko esiluqilima semveliso yakho ezenzekelayo yexesha elizayo.
