Qhov zoo ntawm electron beam xaiv melting

Electron beam direct metal forming technology siv high-zog electron beam ua cov khoom siv hluav taws xob. Kev sib sau ua ke tuaj yeem ua tau los ntawm kev tswj cov hlau nplaum deflection coils yam tsis muaj kev ua haujlwm tsis zoo, thiab lub tshuab nqus tsev ntawm cov kab hluav taws xob tuaj yeem tiv thaiv cov hmoov hlau los ntawm oxidized thaum lub sij hawm ua kua theem sintering lossis melting. . Piv nrog rau laser, electron beam muaj qhov zoo ntawm kev siv lub zog siab, qhov tob ntawm qhov kev txiav txim siab, cov khoom siv siab absorbing tus nqi, stability thiab tsis tshua muaj kev khiav hauj lwm thiab txij nkawm nqi. Qhov zoo ntawm EBM thev naus laus zis yog qhov ua tau zoo ntawm cov txheej txheem tsim, me me deformation ntawm cov khoom, tsis muaj hlau txhawb thaum lub sij hawm tsim cov txheej txheem, denser microstructure, thiab lwm yam. Lub deflection ntawm lub laser yuav tsum tau siv lub galvanometer, thiab kev sib hloov ceev ntawm lub galvanometer siab heev thaum lub laser scanned ntawm ib tug high speed. Thaum lub zog laser loj, galvanometer xav tau lub tshuab cua txias dua, thiab qhov hnyav ntawm lub galvanometer nce ntxiv. Yog li ntawd, thaum siv lub zog ntau dua scanning, scanning ceev ntawm lub laser yuav raug txwv. Thaum luam theej duab ntau qhov sib sau, qhov ntev ntawm lub laser tseem nyuaj rau kev hloov pauv sai. Lub deflection thiab focusing ntawm lub electron beam yog ua tiav los ntawm ib tug sib nqus teb, thiab lub deflection tus nqi thiab tsom ntev ntawm lub electron beam yuav ceev thiab rhiab heev tswj los ntawm kev hloov lub zog thiab kev taw qhia ntawm lub teeb liab hluav taws xob. Lub electron beam deflection tsom qhov system yuav tsis cuam tshuam los ntawm cov hlau evaporation. Thaum cov hlau yog melted los ntawm laser thiab electron beam, cov hlau vapor yuav dispersed nyob rau hauv tag nrho cov tsim qhov chaw, thiab cov hlau zaj duab xis yuav plated nyob rau saum npoo ntawm txhua yam khoom nyob rau hauv kev sib cuag. Lub deflection thiab tsom ntawm cov nqaj hluav taws xob yog tag nrho ua tiav hauv qhov chaw sib nqus, yog li nws yuav tsis cuam tshuam los ntawm cov hlau evaporation; laser galvanometers thiab lwm yam khoom siv kho qhov muag muaj qhov cuam tshuam rau evaporation kuab paug.
