Vacuum diffusion vuam txheej txheem ntawm cov kua txias phaj
Lub tshuab nqus tsev vacuum diffusion vuam tshuab yog hais txog cua sov ob lub tiaj thiab du vuam qhov chaw rau qhov kub thiab txias nyob rau hauv ib lub tshuab nqus tsev kawm ntawv. Tsis tas yuav ntxiv cov hlau los yog cov hlau nruab nrab, nyob rau hauv ib txhij ua haujlwm ntawm qhov kub thiab txias, tom qab micro yas rheology, lawv nyob rau hauv kev sib cuag nrog ib leeg, thiab cov electrons, atoms los yog molecules ntawm kev sib cuag nto ntawm lub vuam yog diffused thiab xa mus rau. Ib leeg, Thiab tsim ionic bond, hlau daim ntawv cog lus los yog covalent daim ntawv cog lus. Tom qab ib lub sij hawm ntawm kev txuag hluav taws xob, qhov muaj pes tsawg leeg thiab cov qauv ntawm qhov chaw vuam yog homogenized kom ua tiav cov txheej txheem metallurgical txuas.
Qhov zoo ntawm Vacuum diffusion vuam txheej txheem:
1. Cov txheej txheem vuam yog txheej txheem diffusion tom qab tsim kev sib koom ua ke yam tsis muaj kev koom tes ntawm cov kua theem. Cov muaj pes tsawg leeg thiab cov qauv yog tag nrho raws li cov matrix, tsis muaj raws li cam khwb cia qauv tseem nyob rau hauv kev sib koom tes, thiab cov thawj interface ploj tag. Yog li ntawd, lub cev, tshuaj thiab txhua yam khoom ntawm lub hauv paus hlau tuaj yeem khaws cia.
2. Vim hais tias lub matrix ntawm diffusion vuam tsis overheated los yog melted, nws muaj peev xwm weld yuav luag tag nrho cov hlau thiab non-metallic cov ntaub ntawv uas tsis ua puas lub zog ntawm cov ntaub ntawv uas yuav tsum tau welded. Nws yog tshwj xeeb tshaj yog haum rau cov ntaub ntawv uas nyuaj rau kev ua tiav los ntawm kev siv vuam dav dav, los yog cov ntaub ntawv uas tuaj yeem welded tab sis nws cov kev ua tau zoo thiab cov qauv yooj yim rau kev puas tsuaj loj hauv cov txheej txheem vuam.
3. Nws tuaj yeem vuam ntau hom thiab txawm tias cov khoom sib txawv heev. Xws li cov hlau tsis sib xws, hlau thiab ceramics thiab lwm yam ntaub ntawv uas yog immiscible kiag li hauv metallurgy.
4. Cov qauv sib txawv thiab cov thickness zoo sib txawv kuj muaj.
5. Lub Uniform cua sov, tsis muaj deformation ntawm weldment thiab tsis residual kev nyuaj siab. Ua kom lub workpiece tuav siab precision geometric loj thiab cov duab.
Hauv qee cov kua txias txias thiab kua txias phaj nrog cov qauv tsim tshwj xeeb, nyob rau hauv cov xwm txheej ntawm thaj chaw loj thiab micro channel, lub tshuab nqus tsev diffusion vuam yog qhov kev xaiv zoo tshaj plaws kom paub qhov vuam ntawm cov khoom no.
