3D luam ntawv (Peb Dimensional Printing) yog ib qho ntawm cov txheej txheem ceev ceev. Siv cov ntaub ntawv nplaum xws li cov hmoov yas lossis hlau, los ntawm lub hauv paus ntsiab lus ntawm cov khoom sib cais, raws li cov qauv peb-dimensional khoom, los ntawm txheej txheej software, txheej txheej raws li ib qho thickness, peb-dimensional digital qauv yog hloov dua siab tshiab rau hauv ob-seem. dav hlau qauv nrog nyias tuab heev. Lub tshuab luam ntawv txheej los ntawm txheej los ua ib qho khoom siv lub cev.
Kev tsim ntawm GR5 titanium alloy yog Ti-6Al-4V, uas belongs rau (+) hom titanium alloy. Nws muaj cov khoom zoo txhua yam thiab txhua yam khoom, muaj zog tshwj xeeb, zoo corrosion kuj, zoo biocompatibility, thiab lwm yam. Tsis tas li ntawd, yog siv dav. Nyob rau hauv aviation, petrochemical, biomedicine thiab txawv teb.Qhov tsab xov xwm no piv ob peb lub ntsiab kev npaj rau 3Dprinting titanium alloy hmoov, xaiv lub plasma tig cathode zoo rau plantitanium alloy hmoov, tshuaj xyuas lub balling system ntawm titanium composite hmoov, ua exploratory soj ntsuam ntawm txoj kev loj hlob. Cov txheej txheem kev kho cua sov tseem ceeb tau txheeb xyuas los muab qhov tsim nyog theoretical hauv paus rau daim ntawv thov ntawm 3D tshuab luam ntawv GR5 titanium alloy.
Txoj kev npaj ntawm 3D luam ntawv khoom GR5 alloy hmoov
Muaj ntau hom 3D luam ntawv nyob rau hauv lub teeb ntawm ntau yam ntaub ntawv. Hlau hmoov yog ib qho ntawm cov khoom tseem ceeb rau 3D luam ntawv. Cov hmoov hlau nrog ntau dua immaculateness yuav tsum tau siv los ua cov khoom tsis zoo. Cov ciam teb tseem ceeb ntawm cov hmoov sib xyaw ua ke sib xyaw ua ke, molecule duab, molecule loj thiab molecule loj ncig. , smoothness, thiab lwm yam. ho cuam tshuam qhov xwm ntawm 3D luam ntawv. Titanium thiab titanium alloy cov ntaub ntawv muaj cov khoom tshwj xeeb. Tom qab npaj rau hauv cov hmoov, lawv tuaj yeem ua tau raws li qhov tsim nyog ntawm 3D luam ntawv hlau cov ntaub ntawv, tab sis qhov kev npaj yog qhov nyuaj heev. Raws li tam sim no, cov kev nce qib tseem ceeb rau kev npaj ntawm feem ntau paub tab 3D luam ntawv titanium alloy hmoov muaj xws li: ntshav pivoting anode txheej txheem, ntshav hlau thiab roj atomization zoo, thiab lwm yam.
Cov khoom tsim los ntawm 3D luam ntawv los ntawm titanium alloy hmoov muaj qhov zoo ntawm cov hardness siab, qis thermal expansion coefficient thiab zoo corrosion kuj.
1. Sib piv peb txoj kev npaj tseem ceeb ntawm titanium alloy hmoov
⑴ Plasma rotating electrode txoj kev
Txoj kev npaj no yog tias cov electrode yog ua los ntawm cov hlau lossis hlau, thiab qhov kawg saum npoo yog rhuab los ntawm arc thiab melted rau hauv cov kua. Nyob rau hauv qhov kev txiav txim ntawm nws tus kheej high-ceev centrifugal quab yuam, cov kua yog muab pov tseg thiab crushed rau hauv zoo tee dej, thiab ces condensed rau hauv hmoov. Cov txheej txheem kev npaj no tuaj yeem kho cov electrode ceev Tswj cov particle loj ntawm cov hmoov yog ib txoj hauv kev zoo tshaj plaws kom tau txais cov hmoov kheej kheej. Nws muaj cov yam ntxwv ntawm siab sphericity, zoo hmoov fluidity, siab loading ceev, du nto, txhim khu kev qha luam ntawv txheej txheem tswj, thiab yog tsis nquag mus rau qhov tsis xws luag xws li precipitated gases thiab tawg. Txawm li cas los xij, vim qhov kev txwv ntawm kev ceev centrifugal, qhov loj me me ntawm cov titanium alloy hmoov uas ua tau yog qhov ntxhib, thiab cov khoom loj me me yog cov concentrated, uas ua rau cov nqi siab thiab cov khoom lag luam tsawg.
⑵ Plasma hlau atomization txoj kev
Txoj kev npaj no siv cov xov hlau sib txawv raws li cov khoom siv raw thiab ua rau lawv ua cov hmoov kheej kheej. Nws yog thawj zaug tsim los ntawm Canadian Raymor lub tuam txhab thiab nws muaj nws tus kheej cov cuab yeej tsim khoom, uas muaj qee yam cuam tshuam hauv kev lag luam. Cov hmoov zoo spherical uas tsim los siv cov cuab yeej no muaj qhov zoo ntawm cov hmoov extraction siab, tsis muaj impurities, thiab kev ua haujlwm siab. Nws yog tsim rau kev loj hlob ntawm titanium alloy hmoov. Txawm li cas los xij, nws kuj tseem muaj cov lej ntawm "satellite balls" thiab adhesion me me, uas muaj kev cuam tshuam me ntsis rau kev ua haujlwm. pom tseeb.
⑶ Gas atomization txoj kev
Cov pa roj atomization txoj kev siv cov cua kub ceev kom tawg cov hlau ua kua dej thiab ua kom khov sai sai rau cov hmoov. Txoj kev no tsuas yog yuav tsum kov yeej lub zog ntawm cov kua hlau atoms kom tawg nws. Qhov tseeb, txhua yam khoom uas tuaj yeem tsim ua kua tuaj yeem siv tau. Rau atomization, lub tshuab nqus tsev atomization thiab inert gas atomization yog tam sim no siv ntau zaus. Titanium alloy hmoov npaj los ntawm roj atomization txoj kev muaj cov yam ntxwv ntawm ceev ceev solidification, tsis muaj hollow hmoov hais, thiab zoo sphericity. Txawm li cas los xij, cov hmoov rho tawm tus nqi qis thiab cov nqi tsim khoom yog siab. Tam sim no, feem ntau hauv tsev atomization tshuab yog siv los tsim titanium thiab titanium alloy hmoov, tab sis cov hmoov rho tawm tsis siab.
2. Sib piv cov txheej txheem npaj sib txawv
Cov txheej txheem kev npaj saum toj no ntawm kheej kheej titanium thiab titanium alloy hmoov yog tam sim no cov lus qhia tseem ceeb ntawm kev tshawb fawb thiab kev sim ntau lawm hauv tsev thiab txawv teb chaws. Thawj txoj kev muaj cov cuab yeej siv qis thiab cov titanium alloy hmoov ua tau zoo sphericity, tab sis qhov loj me ntawm cov hmoov tau txais yog coarse. Qhov no Lub thickness ntawm cov hmoov particle loj tuaj yeem tswj tau los ntawm kev kho qhov tsis zoo. Cov hmoov txhuas ua los ntawm hom thib peb muaj qhov zoo sib xws thiab cov khoom me me, thiab muaj ntau hom kev npaj, tab sis kev siv tshuab hauv tsev tseem tsis tau paub tab. Cov pa roj atomization txoj kev muaj cov hmoov zoo, cov ntsiab lus tsis tshua muaj oxygen, thiab tsis muaj kev tshwj xeeb rau cov khoom siv raw, tab sis cov nqi tsim khoom yog siab.
Ntau txoj kev npaj muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. Tom qab kev tsom xam thiab kev sib piv, plasma rotating electrode txoj kev tau siv rau atomize titanium alloy hmoov, thiab cov nyhuv zoo kawg li.
