I-Diffusion Welding Machine Ichazwe: Izimiso Nezicelo Zezimboni

I-Diffusion welding iyinqubo eqinile-yokuhlanganisa isimo esetshenziswa kabanzi ezimbonini lapho ukuthembeka kwamalungu, ukuqhutshwa kukagesi, -nokuqina kwesikhathi eside kubalulekile. Njengoba izidingo zokukhiqiza ziqhubeka nokukhula emikhakheni efana nokugcinwa kwamandla, izinto zikagesi zikagesi, i-aerospace, nemishini yezimboni ethuthukisiwe, umshini wokushisela ukusabalalisa usuphenduke ithuluzi lokukhiqiza elibaluleke kakhulu.

Ngokungafani nezindlela ezijwayelekile zokushisela ezincike ezintweni ezincibilikayo noma zokugcwalisa, i-diffusion welding yakha isibopho se-metallurgical ngokusakazwa kwe-athomu ngaphansi kwezinga lokushisa elilawulwayo, ingcindezi, kanye nomkhathi. Lo mhlahlandlela uchaza ukushisela okusabalalisa kusuka ezimisweni ezibalulekile kuye{1}}kuzinhlelo zokusebenza zangempela zezimboni zomhlaba wonke, ngokugxila okucacile kokuthi imishini yokushisela isetshenziswa kanjani ekukhiqizeni kwesimanjemanje.

I-Diffusion welding iyinqubo yokushisela eqinile-yesimo lapho izindawo ezimbili zensimbi zihlanganiswa ngokuzibamba ndawonye ngaphansi kwezinga lokushisa eliphakeme kanye nokucindezela isikhathi esilawulwayo. Izinga lokushisa elisetshenzisiwe lingaphansi kwendawo yokuncibilika yezinto eziyisisekelo, okusho ukuthi akukho chibi elincibilikisiwe elakhiwayo phakathi nenqubo.

Esikhundleni sokuncibilika nokuqinisa, ukubopha kwenzeka ngokusatshalaliswa kwe-athomu kuyo yonke indawo yokuxhumana. Ngenxa yalokho, amajoyinti a-diffusion{1}}ashiselwe ngokuvamile abonisa izakhiwo zemishini nezikagesi eziseduze kakhulu nalezo zesisekelo.

Izici ezibalulekile ze-diffusion welding zifaka ukungabikho kwezinsimbi zokugcwalisa, ukuhlanekezela okuncane, nokungaguquguquki okuhle kakhulu kwamalunga.

Izindlela zokushisela zendabuko ezifana ne-resistance welding, i-laser welding, noma i-brazing zincike ekuncibilikeni noma kuma-alloys okugcwalisa ukuze kudaleke ilunga. Nakuba zisebenza kahle ezinhlelweni eziningi, lezi zindlela zingathula izici ezifana ne-porosity, imifantu, izingcindezi ezisalelayo, noma ukwanda kokumelana nogesi.

I-Diffusion welding igwema lezi zinkinga ngokugcina izinto zisesimweni esiqinile. Lokhu kwenza i-diffusion welding ifaneleke ikakhulukazi-izingxenye zokusebenza okuphezulu lapho ubuqotho obuhlanganyelwe kanye{2}}nokwethembeka kwesikhathi eside kubalulekile.

Ezingeni le-microscopic, izindawo zensimbi azibushelelezi neze. Lapho izingxenye ezimbili zihlangana, ingxenye encane kuphela yendawo engaphezulu ithintwayo. Ekushiseleni okusatshalaliswayo, izinga lokushisa eliphakeme linyusa ukuhamba kwe-athomu, kuyilapho ingcindezi esetshenziswayo ikhuthaza ukuwohloka kwepulasitiki kuma-asperities angaphezulu.

Njengoba indawo yokuxhumana ikhula, ama-athomu aqala ukufuduka kuyo yonke i-interface. Ngokuhamba kwesikhathi, umngcele wangempela awubonakali, wenza isibopho se-metallurgical esiqhubekayo ngaphandle kokuncibilika.

• Izinga lokushisa

Izinga lokushisa lokushisela ngokuvamile lisukela ku-50% ukuya ku-80% wendawo encibilikayo yezinto. Amazinga okushisa aphakeme asheshisa ukusakazeka kwe-athomu, kodwa ukushisa okudlulele kungase kubangele ukukhula okusanhlamvu noma ukuntengantenga kobukhulu. Ukukhetha iwindi lokushisa elilungile kubalulekile ukuze uthole imiphumela engaguquki.

• Ingcindezi

Ingcindezi iqinisekisa ukuthintana okusondelene phakathi kwezindawo, iphazamisa izendlalelo ze-oxide, futhi isekela ukusabalalisa. Ukusatshalaliswa kwengcindezi efanayo kubaluleke kakhulu uma sishisela-indawo enkulu noma izingxenye zezendlalelo eziningi, njengezixhumi zethusi ezilaminated.

• Isikhathi

I-Diffusion welding yinqubo-encike esikhathini. Imijikelezo yokushisela ingasukela emaminithini ambalwa kuye emahoreni ambalwa kuye ngohlobo lwempahla, ukujiya, nokucushwa okuhlangene. Ukuthuthukisa isikhathi somjikelezo kubalulekile ukulinganisa ikhwalithi ehlanganyelwe nokusebenza kahle kokukhiqiza.

• Izidingo Zomkhathi Olawulwayo

Emazingeni okushisa aphakeme, izinsimbi eziningi zi-oxidize ngokushesha lapho zivezwe emoyeni. Izendlalelo ze-oksidi zivimbela kakhulu ukusakazeka kwe-athomu futhi zonakalise ikhwalithi ehlangene. Ngalesi sizathu, i-diffusion welding ngokuvamile yenziwa endaweni ye-vacuum noma ngaphansi kokuvikelwa kwegesi engasebenzi.

Umshini wokushisela uhlanganisa amasistimu evacuum noma amayunithi okulawula igesi ukuze kugcinwe indawo yokushisela ehlanzekile, iqinisekisa amalunga-ekhwalithi ephezulu aphindaphindekayo.

I-Copper ingenye yezinto ezivame ukusabalalisa-ezishiselwe ngenxa yokuguquguquka kwayo okuphezulu kagesi kanye nokuzwela ukumelana namalunga. Imishini yokushisela isetshenziswa kabanzi ekwenzeni izixhumi zethusi eziguquguqukayo, amabhasi ama-laminated, kanye{2}}namakhondakta amanje aphezulu.

Lezi zinto zisetshenziswa kaningi ku-aerospace, izishintshisi zokushisa, namasistimu e-vacuum. I-Diffusion welding inikeza amajoyinti aqinile, avuzayo{1}}aqinile ngaphandle kokwethula izinsimbi zokugcwalisa noma ukuguqula izinto ezibonakalayo.

Ngokulawula inqubo efanele, i-diffusion welding ingahlanganisa izinsimbi ezingafani njengethusi kuye kwensimbi engagqwali noma ithusi ukuya ku-aluminium, okuvumela imiklamo emisha yomkhiqizo okunzima ukuyifinyelela ngokushisela okujwayelekile.

Ezinhlelweni zokugcina amandla, okokusebenza kokusabalalisa amandla, kanye ne-electronics yezimboni, izixhumi zethusi eziguquguqukayo kufanele zithwale i-high current ngenkathi zivumela ukunwetshwa okushisayo nokudlidliza. I-Diffusion welding inikeza ukumelana okuphansi kokuxhumana, ukuzinza okuhle kakhulu kokushisa, nokungaguquguquki okuphezulu kuwo wonke amaqoqo okukhiqiza.

Amamojula ebhethri namakhabethe okugcina amandla adinga ukuxhunywa kukagesi okuthembeke kakhulu. Imishini yokushisela inika amandla ukuhlangana kwezingxenye zethusi ezendlalelo eziningi ngekhwalithi ephindaphindekayo, esekela{1}}ukukhiqiza okukhulu.

I-Diffusion welding isetshenziselwa kakhulu izakhiwo zangaphakathi eziyinkimbinkimbi, izingxenye ze-vacuum, kanye{0}}nokuhlanganiswa kwamandla aphezulu endaweni ye-aerospace kanye nezinhlelo zokusebenza ezithuthukisiwe zezimboni lapho ukwethembeka okuhlanganyelwe-kungaxoxiswana khona.

I-Diffusion welding idinga ukulawula okunembile kwezinga lokushisa, ukucindezela, nomoya. -Izisetshenziswa zenjongo evamile azikwazi ukuhlangabezana nalezi zimfuneko ngokungaguquki.

Imishini yesimanje yokushisela i-diffusion isebenzisa-ukulawula izinga lokushisa okunembe kakhulu, okuvamise ukugcina ukuzinza phakathi kuka-±1℃. Lokhu kuqinisekisa izimo zokusatshalaliswa ezingaguquki kuyo yonke imijikelezo yokukhiqiza.

I-Servo noma amasistimu we-hydraulic pressure ahlinzeka ngamandla alawulwayo, afanayo kuwo wonke umjikelezo wokushisela, okubalulekile-emajoyini endawo amakhulu nezingxenye zezendlalelo eziningi.

Amaphampu e-vacuum ahlanganisiwe kanye nezinhlelo zokulawula igesi agcina indawo yokushisela ehlanzekile, enciphisa i-oxidation futhi athuthukise ukuphindaphinda ngokuhlanganyela.

Lapho uhlola ubuchwepheshe bokushisela, abakhiqizi kufanele bahlole kokubili izidingo zomkhiqizo kanye nemigomo yokukhiqiza. I-Diffusion welding ifaneleka kakhulu izinhlelo zokusebenza lapho ukusebenza nokuthembeka kudlula ukucatshangelwa kwesikhathi somjikelezo.

Izinto eziyinhloko zokuhlola zihlanganisa amandla emishini, usekelo lwenqubo, amandla okuzenzakalela,{0}}nokutholakala kwesevisi yesikhathi eside.

Isiphetho

A umshini wokushisela we-diffusioninika amandla-ukuxhumana kwezwe okuqinile ngezinga lokushisa elilawulwayo, ingcindezi, nomoya, ikhiqize amalunga anezakhiwo eziseduze nesisekelo. Lokhu kwenza i-diffusion welding ibe yisixazululo esinamandla sezixhumi zethusi, amasistimu okugcina amandla, izingxenye ze-aerospace, nezinye{2}}uhlelo lokusebenza olunokwethenjelwa okuphezulu.

Njengoba ukukhiqizwa komhlaba wonke kuqhubeka nokuqhubekela phambili ekusebenzeni okuphezulu kanye namazinga afanayo, imishini yokushisela i-diffusion idlala indima ebaluleke kakhulu ezindaweni zokukhiqiza ezithuthukile.
