Yintoni Ukwabiwa Kwelizwe Eliqinileyo?
I-Solid state diffusion yintshukumo yee-athom, ii-ion okanye ezinye iintlobo zezinto eziqinileyo. Intshukumo icotha kakhulu kunokusasazwa kulwelo okanye kwirhasi kuba iiathom kwindawo eqinileyo zibanjwa ngaphakathi kolwakhiwo olucwangcisiweyo.
Ukusasazwa kunokwenzeka ngeendlela ezininzi, kubandakanya ukuhamba ngeglasi yekristale, ecaleni kwemida yeenkozo kunye nezinto ezikufutshane. Indlela elawulayo ixhomekeke kwizinto eziphathekayo, ubushushu, i-microstructure kunye nexesha lokucubungula.
Ubushushu bunefuthe elimandla kwisantya sokusasazwa. Xa iqondo lobushushu linyuka, iiathom ziba namandla angakumbi okutshintsha indawo. Oku akuthethi ukuba impahla kufuneka inyibilike. Intshukumo yeathom ingenzeka ngelixa izinto zihlala ziqinile.
Kwi-welding yokusasazwa, le ntshukumo yeathom inegalelo kuphuhliso lwebhondi emva kokuba imiphezulu icociwe, ilungelelanisiwe kwaye icinezelwe ukuba isondele ngokwaneleyo.
I-Solid State Diffusion yenza njani i-Welded Joint?
1. Ukulungiswa komphezulu
Iindawo zokukhwelana ziyacocwa ukuze kususwe ioli, i-oxidi ekhululekile kunye nolunye ungcoliseko. Ukuthe tyaba komphezulu kunye noburhabaxa nazo zichaphazela indawo yonxibelelwano yokwenyani.
Nkqu nomphezulu obonakala ugudileyo uqulethe amanqaku aphezulu naphantsi. Ukuba iinxalenye azihambelani ngokusondeleyo, amacandelo amakhulu ojongano angahlala ahlukene.
2. Ulungelelwaniso kunye noQhagamshelwano
Amalungu afakwe kwisixhobo esifanelekileyo kwaye adityaniswe. Amandla asetyenziswayo anceda ukunciphisa izikhewu kwaye anyuse indawo apho umphezulu uchukumisa khona.
Amandla afunekayo axhomekeke kwizinto eziphathekayo, indawo edibeneyo, ubushushu kunye nesixhobo. I-Diffusion welding akufuneki ihlale ichazwa njengenkqubo yoxinzelelo oluphezulu-kuba izicelo ezahlukeneyo zisebenzisa amanqanaba amandla awohlukeneyo.
3. Ukufudumeza okulawulwayo
Umdibaniso ushushu ngelixa izinto ezisisiseko zihlala zingaphantsi kwamaqondo obushushu anyibilikayo. Ukufudumeza kwandisa ukuhamba kweathom kwaye kunokwenza ukuba imathiriyeli ibe lula ukuyikhubaza kwindawo yojongano.
Ubushushu bunokubonelelwa ngesithando somlilo, inkqubo yokungeniswa, ukuchasana nombane okanye omnye umthombo olawulwayo. Indlela yokufudumala ixhomekeke kwi-workpiece kunye noyilo lwezixhobo.
4. Uphuhliso lwe-Interface
Njengoko umphezulu uhlala phantsi kobushushu kunye nokunyanzeliswa, uqhagamshelwano lwendawo luyaphucuka kwaye iiathom zihamba ngapha okanye kufutshane nojongano lwentsusa.
Iindlela ezininzi zinokuba negalelo, ukuquka ukuguqulwa kwendawo, ukushukuma kwemida{0}}yokutya okuziinkozo kunye nokusasazwa kweeleti. Ukubaluleka kwabo kuxhomekeke kwizinto eziphathekayo kunye neemeko zokubambisana.
Ujongano alupheli ngokuzenzekelayo. Isiphumo sokugqibela sixhomekeke ekulungisweni komphezulu, ubushushu, amandla, ixesha lokubamba kunye nokuhambelana kwezinto.
5. Ukupholisa nokuHlola
Emva kwexesha elifunekayo lokubamba, idibeneyo ipholile ngokwenkqubo evunyiweyo. Amandla anokugcinwa ngexesha lesigaba sokupholisa ukulawula intshukumo okanye ukuguqulwa.
I-joint ke ihlolwe kusetyenziswa indlela yokuhlola efunekayo kwicandelo. Imbonakalo yodwa ayinakuqinisekisa imeko epheleleyo ye-bonding interface.
Yintoni eLawula ukuSasazeka koBume obuSolid ngexesha le-Welding?
Izinga lokusabalalisa kunye nomgangatho wokudibanisa kuchaphazelekayo kwiimeko ezininzi ezidibeneyo. Ixabiso lobushushu okanye ixesha lokubamba akufuneki livavanywe lodwa.

Akukho pharamitha yendalo yonke isetiwe kwimeko eqinileyo yokusasazwa kwewelding. Iimeko zenkqubo kufuneka ziphuhliswe kwizinto ezichanekileyo, imilinganiselo edibeneyo kunye neemfuno zokwamkelwa.
I-Solid-State Diffusion Welding vs. Fusion Welding
Umahluko omkhulu kukuba ingaba isiseko sinyibilika kwi-joint.
| Inkqubo uphawu | Okuqinileyo-I-State Diffusion Welding | Fusion Welding |
| Isiseko-semeko yezinto | Ihlala iqinile | Inyibilika ekuhlaleni ukwenza i-weld pool |
| Eyona ndlela yokudibanisa | Uqhagamshelwano olusondeleyo, ukuguqulwa kwendawo kunye nokusabalalisa | Ukunyibilika kulandele ukuqina |
| Izinto zokugcwalisa | Ngokuqhelekileyo ayifuneki kwintsebenziswano-yento efanayo | Ingasetyenziswa okanye ingasetyenziswa |
| I-weld bead ebonakalayo | Ngokuqhelekileyo ukungabikho | Okuqhelekileyo kwi-arc kunye neenkqubo ezifanayo zokudibanisa |
| Ulawulo lwenkqubo engundoqo | Umphezulu, ubushushu, amandla, ixesha kunye nomoya | Igalelo lobushushu, ukuhamba, ukukhusela kunye nokuqinisa |
| Izithintelo eziqhelekileyo | Ukulungiswa komphezulu, ixesha lomjikelo kunye neemfuno zezixhobo | Ukuqiniswa kweziphene, ukugqwetheka kunye nobushushu{0}}iipropati ezichaphazelekayo |
I-welding ye-diffusion ayidali i-weld bead eqhelekileyo. Nangona kunjalo, akuchanekanga ukuthetha ukuba izinto eziphathekayo azikho umphumo we-thermal. Izinto ezidibeneyo kunye nezijikelezileyo zisabonakaliswa ukushisa, kwaye iimpawu zabo zingatshintsha ngokuxhomekeke kwiqondo lokushisa kunye nexesha lokubamba.
Kutheni Usebenzisa inkqubo eSolid-yeNkqubo yokuDityaniswa kweLizwe?
Ukugcina izixhobo ezisisiseko ngaphantsi kwamaqondo obushushu anyibilikayo kuthintela ichibi elinyibilikayo le-weld kunye nenqanaba lokuqina elifunyenwe kwi-fusion welding. Oku kunokuba luncedo xa icandelo lifuna imilinganiselo elawulwayo, ukumakishwa komhlaba okulinganiselweyo okanye umdibaniso ngaphandle kokugcwalisa.
Iingenelo ezinokubakho ziquka:
- Akukho ntsimbi yesiqhelo yokudityaniswa kwe weld
- Ukunyibilika kobuninzi obuncinci kunye nokuqina
- Ukukwazi ukudibanisa izinto ezinomaleko okanye ezincinci
- Ukufaneleka kweendibaniso ezikhethiweyo ezifanayo kunye nezingafaniyo
- I-deformation elawulwayo xa inkqubo kunye nezixhobo ziphuhliswa ngokufanelekileyo
Ezi zibonelelo azizenzekeli. Ubushushu obugqithisileyo, amandla angalinganiyo, ukulungiswa komphezulu okulambathayo okanye ukudityaniswa kwezinto ezingafanelekanga kusenokubangela i-deformation, i-bonding engaphelelanga okanye i-brittle interface phases.
Ukudibanisa{0}}okungafaniyo ngentsimbi kufuna ukhathalelo olulodwa. Ubhedu kunye ne-aluminiyam, umzekelo, zineendlela ezahlukeneyo zokuziphatha kwe-thermal kunye noomatshini, kwaye iikhompawundi ze-intermetallic ezingafunwayo zinokuvela ukuba inkqubo ayilawulwa.
Amandla adibeneyo kunye ne-conductivity yombane kufuneka iqinisekiswe ngokuvavanya kunokuba kucingelwa ukuba ilingana nezinto ezisisiseko.
I-Solid State Diffusion kwi-Flexible Busbar Welding
Iibhasi zebhasi eziguquguqukayo ziqhele ukwenziwa ngobhedu olupakishweyo okanye iifoyile zealuminiyam. Icandelo eliphakathi lihlala liguquguquka, ngelixa iziphelo zefoyile zidityanisiwe ukuze zenze iindawo eziqinileyo zokudibanisa
Kwinkqubo yokumelana-nobushushu bebhasi ye-welding, isitaki sefoyile sibekwe phakathi kobuso besixhobo. Ukushisa kombane kunye namandla omatshini asetyenziswa kwindawo yokudibanisa ngokweshedyuli ye-welding eqinisekisiweyo
Isiphumo sixhomekeke ngaphezu kwenani leengqimba zefoyile. Uphuhliso lwenkqubo kufuneka luqwalasele:
• Imathiriyeli yefoyile kunye nemeko yomphezulu
• Ubutyebe bomaleko ngamnye
• Iyonke indawo enqamlezileyo{0}}yecandelo
• Ubude bebhondi kunye nobubanzi
• Uqhagamshelwano lwezixhobo
• Amandla asetyenziswayo
• Umjikelo wokufudumeza kunye nokupholisa
• Uvavanyo olufunekayo lombane kunye noomatshini
Ubhedu kunye ne-aluminium akufanele zisebenzise izicwangciso zenkqubo efanayo ngaphandle kokuqinisekiswa. Ukuxhathisa kwabo kombane, i-thermal conductivity, i-oksidi yokuziphatha kunye neempawu ze-deformation zahlukile
Ukufumana ulwazi malunga nesicelo kunye nezixhobo, jonga iHaifei'soomatshini bokuwelda bobhedukwayeizixhobo zokuwelda usasazo aluminiyam.
Ngaba i-Diffusion Soldering ikwayinkqubo eZinzileyo-yeState?
Isoda yosasazo, ekwabizwa ngokuba yi-transient liquid phase bonding, kufuneka yohlulwe kwinto eqhelekileyo eqinileyo{0}}kwistate diffusion welding.
I-welding yesiqhelo yokusasazwa igcina izinto zokukhwelana zikwimeko eqinileyo. I-Diffusion soldering isebenzisa i-interlayer eyenza okwethutyana isigaba solwelo. Ukusasazwa emva koko kutshintsha ukwakheka komdibaniso, kuvumela umaleko wolwelo ukuba uqine ngelixa ubushushu lusabanjwa.
Zombini iinkqubo zibandakanya ukusasazwa, kodwa imeko yojongano kunye neemfuno zezixhobo zahlukile.
