Tus ua hauj lwm lub ntsiab cai ntawm diffusion vuam tshuab tsuas yog suav nrog cov kauj ruam tseem ceeb hauv qab no thiab cov khoom siv:
Kev ua haujlwm ua haujlwm yooj yim: diffusion vuam tshuab ua haujlwm nyob rau hauv ib puag ncig lossis kev tiv thaiv kev tiv thaiv ib puag ncig, thiab siab kom cov khoom tau paub atomic diffusion infusion incicidusion. Cov txheej txheem tshwj xeeb tau muab faib ua peb theem:
Tog saum npoo: Workpiece yuav tsum welded yog nyob rau hauv kev txiav txim siab nyob rau hauv qhov kev txiav txim siab nyob rau hauv qhov siab thiab kub, thiab micro-conflation kom nce thaj chaw tiv tauj tiag tiag. Lub tshuab nqus tsev ib puag ncig tshem tawm oxide zaj duab xis thiab paug kom ntseeg tau tias muaj cov hlau sib chwv.
Interface diffusion theem: kev kub siab ua rau atoms rau diffuse hla lub interface los ua daim hlau metallurgical. Siab txhawb nqa ze ze ntawm lub interface thiab txo tus porosity.
Ntim domusion thiab Link City Miduse rau hauv cov khoom siv, cov ciaj ciam av ploj mus, thiab ib qho kev sib txuas metallurgical yog tsim.
Cov Txheej Txheem Tseem Ceeb:
Kub: txiav txim siab atomic diffusion tus nqi. Kev kub dhau heev yuav ua rau cov noob qoob loo grainening. Cov khoom raug yog {{{{0}}}. 5 ~ 0.8 lub sij hawm lub melting taw tes ntawm cov khoom.
Siab: Txhawb nqa ze ze ntawm lub interface thiab txo cov porosity. Cov khoom tau yog 5 ~ 50MPA.
Lub sijhawm: cuam tshuam rau qhov tob diffusion. Ntev dhau yuav txo qis kev ua tau zoo. Cov li yog 10 feeb txog ntau teev.
Lub Tshuab Nqus: Tiv thaiv cov oxidation thiab tshem tawm cov adsorbed thaj chaw. Lub tshuab nqus tsev feem ntau yog tsawg dua los yog sib luag rau 10⁻³pa.
Cov khoom siv sib xyaw thiab cov haujlwm ua haujlwm:
Cov Cheebtsam Tseem Ceeb: suav nrog lub nqus dej nqus (tshuab nqus mis + cov cua sov thiab kev tswj hwm cua sov (plc lossis khoos phis tawm ntawm lub taub hau (plyc lossis khoos phis tawm ntawm lub taub hau)
Raug excurflow: kev ua haujlwm ua haujlwm (kev sib dhos ua ke, cua sov, ua kom sov thiab kev ntxhua khaub ncaws, cua txias thiab siab nyem.
Cov Nta Cov Txuj Ci:
Cov txiaj ntsig zoo: Tsis tas yuav yaj cov khoom siv ntawm niam txiv, tsis txhob muab cov khoom siv ua kom sov, hws thiab lwm yam kev sib tw tshuab hluav taws xob, haum rau cov ntaub ntawv sib txuas. High-precision, high-zog sib koom ua ke, ib puag ncig phooj ywg, tsis muaj qhov sib xyaw ua pa, tsis muaj qhov xav tau ntim khoom.
Cov kev txwv: Kev voj kauj ruam ntev, tsis haum rau huab hwm coj ntau lawm; tus nqi siab.
