Vacuum diffusion welding kua phaj
Lub tshuab nqus tsev vacuum diffusion vuam tshuab yog txheej txheem vuam tshwj xeeb tsim sai sai kom tau raws li cov kev xav tau ntawm kev tshawb fawb thiab thev naus laus zis xws li atomic zog, aviation, aerospace thiab hluav taws xob kev lag luam. Nws yog los ua kom sov ob lub tiaj tiaj thiab du vuam qhov chaw mus rau qhov kub thiab txias hauv qee lub tshuab nqus tsev. 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 los tsim ion bonds, Cov hlau daim ntawv cog lus los yog covalent daim ntawv cog lus, tom qab ib tug lub sij hawm ntawm kev txuag tshav kub, homogenizes muaj pes tsawg leeg thiab cov qauv ntawm lub vuam cheeb tsam, thiaj li mus cuag ib tug tiav metallurgical kev twb kev txuas txheej txheem.
Yog li ntawd, diffusion welding feem ntau yog nyob ntawm kev sib cuag tom qab micro yas rheology ntawm qhov chaw vuam, thiaj li ua kom muaj coob tus atoms diffuse ib leeg. Nws tuaj yeem ua tiav cov haujlwm vuam uas nyuaj rau kev paub los ntawm lwm txoj kev vuam, thiab tseem tuaj yeem paub qhov vuam ntawm cov khoom sib txawv xws li kev sib koom ua ke, siab melting point hlau thiab cov hlau tsis yog hlau, kom lawv tuaj yeem tau txais cov pob qij txha zoo. .
Cov yam ntxwv ntawm lub tshuab nqus tsev vacuum diffusion vuam
1.Cov txheej txheem vuam yog txheej txheem ntawm kev kho diffusion tom qab kev sib koom ua ke tsis muaj kev koom tes ntawm cov kua theem lossis tsuas yog theem hloov pauv tsawg. 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 lub matrix ntawm diffusion welding 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 yuav tsum tau welded.
3. Cov khoom siv sib txawv tuaj yeem txuas ua ke.
4.Nws tuaj yeem vuam workpieces nrog cov qauv nyuaj thiab qhov sib txawv loj thickness.
5.Uniform cua sov, tsis muaj deformation ntawm weldment thiab tsis residual kev nyuaj siab. Khaws lub workpiece nrog high precision nyob rau hauv geometric loj thiab cov duab.
