Puas yog kev lag luam pwm puas siv titanium alloy rau 3D luam ntawv?

Ib, Cov txiaj ntsig thev naus laus zis ntawm 3D luam ntawv siv titanium alloy thiab nws ua haujlwm zoo li cas nrog pwm xav tau
1. Muaj peev xwm ua kom cov qauv nyuaj
Txhua txhua hnub, kev lag luam pwm xav tau ntau thiab ntau qhov nyuaj sab hauv cov dej ntws thiab cov txheej txheem lattice. Txawm li cas los xij, cov txheej txheem ua cov txheej txheem raug txwv los ntawm cov cuab yeej txoj hauv kev thiab pwm tsim, uas ua rau nws nyuaj ua kom siab -cov qauv nyuaj. Nrog titanium alloy 3D luam ntawv, koj tuaj yeem ntim cov ntaub ntawv los ntawm txheej los ua peb - qauv qauv. Qhov no tso cai rau koj ua cov channel sab hauv, nyias- cov qauv phab ntsa, thiab cov kav dej txias tsis zoo uas cov txheej txheem qub ua tsis tau. Piv txwv li, nyob rau hauv txhaj tshuaj pwm, conformal txias raws yuav txiav lub voj voog txhaj tshuaj los ntawm 30% mus rau 50% thiab ua kom cov khoom yield zoo dua. Titanium alloys, zoo li XM{13}}7 pwm hlau, muaj cov thermal conductivity ntawm 30W / (m · K), uas ua rau lawv zoo dua thaum txias thiab ua rau lawv zoo meej rau high-end pwm.
2. Cov txiaj ntsig ntawm kev ua haujlwm ntawm cov khoom siv
Titanium alloys muaj zog thiab lub teeb, uas tuaj yeem ua rau pwm ntev dua thiab siv tau yooj yim dua. Piv txwv li, 1.2709 (18Ni300) martensitic aging steel muaj lub zog tensile ntawm 2000MPa thiab hardness ntawm 50-52HRC. Nws yog qhov zoo rau siab -kev nyuaj siab tuag- casting pwm thiab kav ntev dua peb zaug ntev dua li H13 steel. Tsis tas li ntawd, titanium alloys 'resilience rau corrosion (xws li ruaj khov 316L stainless hlau nyob rau hauv cov xwm txheej ntub dej) tuaj yeem txo cov sij hawm pwm yuav tsum tau ntxuav thiab txo tus nqi ntawm kev siv lawv dhau sijhawm.
3. Kev hloov kho tus kheej thiab hloov pauv sai
Ntau lub sijhawm, ua cov pwm txhais tau tias ua ntau yam kev sim thiab hloov, thiab cov txheej txheem ib txwm siv sijhawm ntev thiab raug nqi ntau. Cov qauv digital tuaj yeem siv ncaj qha los tsim titanium alloy 3D luam ntawv, thiab pwm qauv tsim thiab kev kuaj xyuas tuaj yeem ua tiav hauv ob peb hnub. Qhov no txo ​​qis lub sijhawm nws yuav siv los ua kev tshawb fawb thiab kev txhim kho. Piv txwv li, ib lub tuam txhab ua cov khoom siv tsheb siv titanium alloy 3D luam ntawv los txiav pwm tsim lub sij hawm los ntawm 8 lub lis piam mus rau 2 lub lis piam thiab ua pwm 30% sib dua los ntawm kev tsim lawv nrog cov qauv lattice. Qhov no txuag lub zog thiab ua rau cov txheej txheem khiav yooj yim dua.
2, Feem ntau txoj kev uas titanium alloy 3D luam ntawv yog siv hauv kev lag luam pwm
1. Pwm rau kev txhaj tshuaj
Vim tias titanium alloy muaj cov cua sov ua kom sov thiab tiv taus corrosion, nws yog cov khoom siv zoo tshaj plaws rau kev txhaj tshuaj pwm. Piv txwv li, nyob rau hauv lub tsheb sab hauv pwm, pwm ua siv 316L stainless hlau hmoov thiab SLM tshuab, nrog rau ib tug conformal txias dej channel tsim, txiav lub txhaj molding voj voog ntawm 120 vib nas this mus rau 75 vib nas this thiab nce tus nqi yield mus rau 98%. Tsis tas li ntawd, titanium alloy pwm yog qhov zoo ntawm polishing nto, uas yog qhov tseem ceeb rau kev ua kom siab -cov khoom zoo li cov lo ntsiab muag kho qhov muag.
2. Pwm rau tuag casting
Tuag casting pwm yuav tsum muaj peev xwm tswj tau siab -kub hlau ua kua yaig thiab thermal stress cycles. Titanium alloys 'tsis kam rau thermal tawg thiab hnav tuaj yeem ua rau lub neej ntawm cov pwm tuaj yeem ua rau muaj zog heev. Tom qab kev kho cua sov, aluminium alloy tuag-casting pwm luam tawm nrog 1.2709 hmoov muaj hardness ntawm 50HRC thiab nyob twj ywm suab nrov tom qab 60,000 tuag-casting cycles. Qhov no yog 200% nce hauv kev pabcuam lub neej piv rau H13 steel pwm.
3. Pwm rau cov log tsheb
Kev hnav tsis kam thiab thermal stability ntawm titanium alloy tuaj yeem txhim kho qhov tseeb ntawm cov pwm pwm thaum lawv siv los ua cov qauv. CX (Corrax) stainless hlau hmoov pwm ua nrog SLM thev naus laus zis muaj kev ua haujlwm polishing ntawm A2. Cov qauv kev txhawb nqa lattice txiav cov pwm qhov hnyav los ntawm 30% thiab txhim kho qhov tseeb ntawm cov qauv luam tawm mus rau hauv 0.01mm, uas yog qhov siab - cov log tsheb kawg xav tau.
4. Pwm rau tshuaj
Lub fact tias titanium alloy yog biocompatible muab nws ib tug tshwj xeeb ntug nyob rau hauv lub realm ntawm kev kho mob pwm. Piv txwv li, 3D luam titanium alloy pob txha phaj pwm tuaj yeem raug kho rau txhua tus neeg mob los ntawm kev ua pwm qauv ncaj qha los ntawm lawv cov ntaub ntawv CT. Qhov no txo ​​qis rau lub sijhawm xav tau los npaj rau kev phais thiab ua rau kev cog ntoo kom hloov tau yooj yim.
3, Cov teeb meem uas titanium alloy 3D luam ntawv ntsej muag hauv kev lag luam pwm
1. Tus nqi ntawm cov ntaub ntawv yog siab
Tus nqi ntawm titanium alloy hmoov yog ntau dua li ntawm cov pwm hlau tsis tu ncua. Piv txwv li, 1.2709 hmoov raug nqi kwv yees li 800 yuan ib kilogramme, uas yog peb zaug ntau dua 316L hmoov, uas raug nqi 260 yuan ib kilogramme. Titanium alloy pwm siv sijhawm ntev dua, tab sis tus nqi siab ntawm kev ua rau lawv thawj zaug ua rau nws nyuaj rau siv lawv ntawm qhov loj.
2. Ua kom cov txheej txheem ruaj khov thiab kho cov teeb meem
Muaj teeb meem nrog 3D luam ntawv titanium alloys, xws li spheroidisation, tawg, thiab porosity, uas ua rau pwm tsis zoo. Piv txwv li, hauv SLM thev naus laus zis, yog tias cov hmoov tsis ntws zoo txaus, cov txheej txheem yuav tsis zoo, thiab cov khoom yuav tsum tau ua kom zoo dua los ntawm kev hloov cov ntawv luam tawm (xws li laser fais fab thiab scanning ceev) thiab tom qab- ua haujlwm (xws li kub isostatic nias).
3. Tus nqi ntawm cov khoom siv thiab kev tshaj tawm - ua
High-kawg titanium alloy 3D tshuab luam ntawv, zoo li EOS M400-4, raug nqi ntau dua 10 lab yuan thiab xav tau ib qho kev tiv thaiv roj inert thiab cov cuab yeej tswj qhov kub thiab txias. Qhov no ua rau lawv nyuaj rau siv. Tsis tas li ntawd, titanium alloy pwm yuav tsum tau kho thaum lawv tsim, uas ntxiv rau cov nqi thiab sijhawm nws yuav siv los ua lawv.
