Cov khoom muag
3D luam titanium alloy daim hlau yog titanium alloy nplooj ntawv thiab preformed blanks tsim txheej los ntawm txheej siv advanced additive manufacturing technologies (xws li laser xaiv melting SLM thiab electron beam melting EBM). Cov thev naus laus zis no cuam tshuam los ntawm cov kev txwv ntawm kev ua ib txwm ua, paub txog kev sib koom ua ke ntawm cov txheej txheem nyuaj, muaj cov khoom siv siab heev thiab kev hloov kho cov yam ntxwv, thiab tau siv dav hauv siab -kawg teb xws li aerospace thiab kev kho mob cog.
Core nta
Cov khoom siv zoo heev: Los ntawm kev ua kom zoo, lub zog tensile nyob rau hauv ntsug luam ntawv kev taw qhia Ntau dua los yog sib npaug rau 1100MPa, uas yog 10% -15% siab tshaj qhov nyob rau hauv txoj kab rov tav, ua tau raws li qhov yuav tsum tau ntawm kev ua hauj lwm hnyav.
High compactness: Optimized txheeb ze ntom ntom ntau dua los yog sib npaug rau 99.5% thiab pore loj Tsawg dua los yog sib npaug rau 50μm, kom ntseeg tau qhov zoo ntawm cov khoom.
Tswj tau qhov zoo ntawm qhov chaw: Tus thawj luam ntawv nto roughness Ra=10-30μm, thiab polished nto tuaj yeem ncav cuag Ra Tsawg dua lossis sib npaug li 0.8μm, ua tau raws li qhov yuav tsum tau ua kom nruj rau qhov chaw tiav rau kev kho mob cog.
Kev ntxhov siab qis qis: Kev kho cua sov thiab cov tshuab siv hluav taws xob substrate stripping yog siv kom tsawg dua lossis sib npaug ntawm qhov kev ntxhov siab ntawm 100 MPa, tiv thaiv kev deformation thiab tawg.
Cov txheej txheem thev naus laus zis
Kev npaj hmoov
Plasma Rotary Electrode Method (PREP) yog siv rau kev milling, nrog cov hmoov particle loj ntawm 15-45μm thiab sphericity ntawm> 95%, kom ntseeg tau tias kev ruaj ntseg ntawm cov txheej txheem luam ntawv thiab kev ua haujlwm zoo.
Printing Parameters (SLM txheej txheem)
Laser hwj chim: 200-400W
Txheej thickness: 30-50μm
Scanning ceev: 800-1200mm / s
Tshaj tawm - kev ua haujlwm
Kub isostatic nias: 920℃× 100MPa × 2 h kom tshem tawm cov porosity sab hauv thiab ua kom ceev.
Nqus annealing: 700℃× 4 h txhawm rau txhim kho cov ntaub so ntswg thiab tshem tawm kev ntxhov siab.
Nto xov
Electropolishing (voltage 10-15 V) lossis txhaj tshuaj peening (Al₂O₃grit) kom ua tau raws li qhov xav tau ntawm cov ntawv thov sib txawv
Kev tswj kom zoo thiab cov txheej txheem optimization
Powder zoo tswj: cov ntsiab lus oxygen tsawg dua los yog sib npaug li 0.15%, fluidity Tsawg dua los yog sib npaug rau 25 s / 50g (Hall flow meter), kom ntseeg tau tias luam ntawv zoo los ntawm qhov chaw.
Multi-laser kev sib koom tes scanning: Patented scanning lub tswv yim txo cov thermal kev nyuaj siab thiab txhim kho kev ua tau zoo los ntawm 30%.
Topology optimized kev txhawb nqa qauv: kev txhawb nqa ntse tsim txo cov khoom pov tseg ntau dua 50% thiab txo qhov nyuaj ntawm kev xa ntawv- ua.
Qhov zoo tshaj li kev tsim khoom
Complex qauv kev koom ua ke: Nws tuaj yeem tsim cov kab noj hniav hauv cov kab noj hniav uas nyuaj rau kev ua tiav hauv cov tsoos forging thiab casting (phab ntsa tuab tsawg dua lossis sib npaug li 0.3 hli), thiab cov khoom siv siv ntau dua lossis sib npaug li 90% (tsuas yog forging tsuas yog 20% -40%).
Kev xa khoom sai: Tsis muaj cov cuab yeej xav tau, lub sijhawm ua haujlwm luv dua 70%, haum rau qis - ntim customization thiab iterations ceev.
High℃ntawm kev ywj pheej tsim: Nws txhawb nqa cov qauv sib xws xws li dot matrix thiab hollow kom ua tiav qhov zoo tshaj plaws sib npaug ntawm kev ua tau zoo thiab qhov hnyav.
Peb qhov zoo
Peb lub tuam txhab muaj kev koom tes hauv kev tsim cov khoom siv hlau ntxiv, nruab nrog SLM / EBM siab- cov cuab yeej kawg thiab ua tiav cov ncej- ua cov kab ntau lawm, muab ib qho - nres kev daws teeb meem rau cov hmoov, luam ntawv, xov, thiab kho qhov chaw.
Ua raws li cov qauv kev lag luam thiab cov txheej txheem zoo, thiab muab siab -kev ua tau zoo 3D luam titanium alloy daim hlau rau siab-kawg tsim nrog cov cuab yeej ruaj khov, muaj peev xwm tshaj lij thiab kev xa khoom zoo.
