Lub hauv paus ntsiab lus thiab lwm yam teeb meem ntawm diffusion vuam ua rau cov kua txias phaj
Diffusion vuam yog txheej txheem tseem ceeb hauv kev tsim cov paib homogenizing. Vim tias cov txheej txheem vuam tsis xav tau cov khoom siv vuam ntxiv, nws tuaj yeem siv rau hauv kev tsim khoom loj. Nyob rau hauv xyoo tas los no, qhov kev thov rau cov khoom xws li cov kav dej txias thiab cov taub hau dej txias tau nce ntxiv. Qhov sib txawv ntawm qhov loj me, cov qauv tsim, thiab daim ntawv thov scenarios tau coj ntau tus neeg siv khoom kawg los them sai sai rau nws cov txheej txheem vuam. Diffusion welding thiab brazing yog ob txoj kev siv vuam ntau tshaj plaws.
Diffusion vuam yog ib txoj kev vuam uas nruj nreem nias ob lub workpieces yuav tsum tau welded ua ke thiab heats lawv nyob rau hauv lub tshuab nqus tsev los yog tiv thaiv cua sov rauv, ua rau lub micro yas deformation nyob rau hauv lub me me unevenness ntawm ob qhov chaw vuam, ua tiav kev sib cuag. Tom qab cua sov thiab rwb thaiv tsev, atoms diffuse nrog ib leeg los tsim ib qho kev sib txuas ntawm metallurgical. Hom diffusion vuam no feem ntau hu ua solid-state diffusion.
Piv nrog brazing (ntxiv solder), diffusion welding tuaj yeem txo lub sijhawm ua haujlwm thaum lub sijhawm sib dhos, txuag solder, txo cov pa phem, thiab zam qhov teeb meem ntawm kev tswj tsis zoo ntawm kev thaiv cov dej ntws channel. Qhov smoothness ntawm ob qhov chaw vuam yuav cuam tshuam rau kev sib khi ua haujlwm ntawm vuam. Yog hais tias impurities, txawv teb chaws hais, thiab lwm yam yog adsorbed rau ntawm vuam nto, nws kuj yuav ua rau tsis zoo sealing. Rau diffusion vuam, nws yog qhov zoo tshaj plaws rau ob sab ntawm lub workpiece yuav tsum tau welded kom tiaj tus, uas tuaj yeem ua kom yooj yim rau vuam fixture. Rau cov khoom xws li dej-txias hau, nws muaj peev xwm xav txog CNC machining lub sab hauv ntws channel nta ua ntej, ua raws li diffusion vuam. Tom qab welding tiav, qhov saum npoo tuaj yeem ua precision machined. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias yog tias muaj microchannels sab hauv, lawv tsis yooj yim los ntxuav. Ua ntej kev ua haujlwm thib ob, lub qhov dej nkag thiab qhov hluav taws xob yuav tsum tau thaiv.
