Intshayelelo: IiParameters zeNkqubo ezi-4 ezingundoqo: 1. Ubushushu; 2. Uxinzelelo; 3. Ixesha lokusasaza; 4. Umoya okhuselayo.
1.Ubushushu
- Ubushushu yiparameter elawulayo kwidiffusion welding. YangokuDiffusion Welding Equipmentngoko ke yenzelwe iinkqubo zokufudumeza ezichanekileyo ukuqinisekisa ukusasazwa kwe-athomu ngokufanelekileyo ngaphandle kokonakalisa izinto ezisisiseko. Ngaphakathi kwemida efanelekileyo, amaqondo obushushu aphezulu akhawulezisa inkqubo yokusabalalisa kunye nokuphucula amandla adibeneyo. Ngoko ke, amaqondo obushushu aphezulu kufuneka akhethwe nanini na kunokwenzeka.
- Nangona kunjalo, ubushushu bokufudumala buthintelwa ngamandla{0}}obushushu obuphezulu bezinto zokusebenza kunye nezinto ezilungisiweyo, kunye neempawu zetsimbi ezifana nenguqu yesigaba semathiriyeli kunye nokuphinda kuhlaziywe kwakhona. Xa iqondo lobushushu lidlula ixabiso elithile, ukuphuculwa komgangatho odibeneyo kuya kulinganiselwa kwaye kunokuhla.
- Ubuninzi besinyithi kunye ne-alloys, ukushisa kwe-welding ye-diffusion ukusuka kwi-0.6 ukuya kwi-0.8 amaxesha okunyibilika kwezinto ezisisiseko (Tm, iyunithi K). Kwi-welding yosasazo olubandakanya izigaba zolwelo, ubushushu bobushushu kufuneka bube phezulu kancinane kunendawo yokunyibilika yemathiriyeli ephakathi okanye iqondo lobushushu le-eutectic reaction, kunye nokupholisa okufanelekileyo ngexesha lokuqiniswa kwe-isothermal kunye nezigaba ze-homogenization. Ukuba oomatshini bokuwelda bokusasazwa kwepolymer baxhotyiswe ngethemomitha ye-infrared, baququzelela ulawulo oluchanekileyo lobushushu.
2.Uxinzelelo
- Xa ezinye iiparamitha zihlala zingaguquguquki, uxinzelelo oluphezulu luthanda ukwakheka kwamalungu aphezulu {{0}ezinga eliphezulu. Umda woxinzelelo oluphezulu unyanzeliswa yi-workpiece deformation limitations kunye nomthamo we-tonnage yezixhobo. Kwiwelding yentsimbi eyahlukileyo, uxinzelelo oluphezulu lunceda ukunciphisa okanye ukunqanda i-diffusion voids.
- Uxinzelelo oluqhelekileyo lwe-welding ye-welding lusuka kwi-0.5 ukuya kwi-50 MPa (ngaphandle koxinzelelo olushushu lwe-isostatic). Uxinzelelo olusezantsi lungasetyenziselwa ulwelo-isigaba参与的 welding ye-diffusion; nangona kunjalo, uxinzelelo olugqithisileyo lunokubangela ukuba isinyithi solwelo sicinezelwe ngaphandle, okukhokelela kwimiba yolawulo lokwakheka.
- Kuba uxinzelelo losasazo lunempembelelo encinci ngexesha losasazo lwamva, i-slid-ye-state diffusion welding inokwehlisa uxinzelelo kwizigaba zamva ukunciphisa uguqulo lwe-workpiece.
3. Ixesha lokusasaza
- Ixesha lokusasaza libhekiselele kubude bexesha lokusebenzela ligcinwa kwiqondo lobushushu le-welding, ekufuneka iqinisekise ukuba inkqubo yokusasazwa igqitywe ngokupheleleyo ukufezekisa amandla adibeneyo afunekayo. Ixesha elaneleyo lithintela amandla adibeneyo ekufikeleleni ngokuzinzileyo kumanqanaba ezinto ezisisiseko.
- Ubude obugqithisileyo{0}}ubushushu kunye{1}noxinzelelo oluphezulu{1}nobude bexesha bunika uphuculo olulinganiselweyo kumgangatho odibeneyo kwaye endaweni yoko kunokubangela ukurhawuka kweenkozo ezisisiseko. Ukuze amalungu athambekele ekwenzeni imidibaniso ye-brittle intermetallic, ixesha lokusasazwa kufuneka lilawulwe ukucutha ubungqingqwa be-brittle layer nokuqinisekisa ukusebenza ngokudibeneyo.
- Ixesha lokusasaza alikho inguqu ezimeleyo kodwa ihambelana ngokusondeleyo nobushushu kunye noxinzelelo: amaqondo obushushu aphezulu okanye uxinzelelo olukhulu lufuna amaxesha amafutshane.
- Ukusasaza i-welding kunye ne-intermediate layers, ixesha le-welding lixhomekeke kubukhulu obuphakathi kunye neemfuno zokufana kwesakhiwo esidibeneyo (kubandakanywa nomxholo wesigaba esivumelekileyo). Kwizicelo ezisebenzayo, ixesha le-welding linokuvela kwimizuzu emininzi ukuya kwiiyure ezininzi, kuxhomekeke kwindibaniselwano yeeparamitha zenkqubo.
4.Umoya oKhuselekileyo
- Ubunyulu, izinga lokuhamba, uxinzelelo okanye inqanaba le-vacuum, kunye nesantya sokuvuza komoya okhuselayo kuchaphazela ngokuthe ngqo umgangatho odibeneyo. Irhasi yokhuseleko esetyenziswa ngokuqhelekileyo yiargon, enamanqanaba aqhelekileyo okufunxa (1-}20)×10⁻³ Pa. Ezinye izinto zingasebenzisa initrogen, ihydrogen, okanye ihelium.
- Kwi-superplastic forming kunye ne-diffusion welding composite process, i-argon yoxinzelelo olubi (i-vacuum ephantsi) isoloko isetyenziselwa ukukhusela iindawo zetsimbi. Kwimathiriyeli eyenzeka kwinguqu yesigaba ngexesha lokupholisa kunye nemathiriyeli enqabileyo efana neeseramikhi, imilinganiselo yokufudumeza kunye nokupholisa kufuneka ilawulwe.
- Kwi-eutectic reaction diffusion welding, iireyithi zokufudumeza ezicothayo ngokugqithisileyo zinokubangela utshintsho lokwakheka komphezulu wonxibelelwano ngenxa yokusasazwa, okuchaphazela ukusebenza kwe-eutectic ukunyibilika.
Ukuqukumbela
Ukuqonda iiparamitha ze-welding ze-diffusion kufuna ukuqonda zombini iziphumo zomntu ngamnye kunye nokusebenzisana kwazo. Ngokulawulwa komgangatho wobushushu, uxinzelelo, ixesha kunye nomoya, abavelisi banokuvelisa amakhonkco aneempawu zoomatshini ezisondela kubuchule bemathiriyeli esisiseko. NjengokoDiffusion Welding Equipment iye iphucuke ngakumbi, ukuphunyezwa kokuqina, iiparamitha eziphuculweyo zifikeleleka ngakumbi, ukwandisa amathuba osetyenziso kuwo wonke ama-aerospace, amandla, kunye namacandelo okuvelisa aphuhlileyo.
