Yog tias koj tau txais sintered titanium hmoov lim cov ntsiab lus rau cov tshuaj, tshuaj, los yog siab -purity industrial applications, koj yuav tau ntsib tus nqi tsis meej pem. Ib daim cartridge 10-inch yuav raug hais txog $50 los ntawm ib tus neeg muag khoom thiab $500 los ntawm lwm tus. Txawm hais tias qhov pom kev pom feem ntau zoo sib xws- lub tog raj kheej nyiaj hlau nrog cov phab ntsa ntxeem tau-cov qauv tsim khoom, cov ntaub ntawv pov thawj, thiab kev ua haujlwm tau zoo sib txawv.
Kev nkag siab txog tus nqi tsav tsheb no yog qhov tseem ceeb rau cov kws tshaj lij kev muag khoom thiab cov neeg saib xyuas cov nroj tsuag kom tsis txhob them nyiaj ntau dhau rau cov yam ntxwv tsis tsim nyog lossis, qhov tseem ceeb tshaj, nyob rau hauv - nqis peev rau hauv ib feem uas ua rau lub cev tsis ua haujlwm, kev tsiv teb tsaws chaw, lossis kev poob qis dua.
Ntawm no yog ib qho kev cuam tshuam ntawm vim li cas kev lag luam tus nqi rau sintered titanium lim spans xws li dav spectrum.
1. Raw Khoom: Titanium hmoov Specification
Tus nqi ntawm cov khoom siv raw yog lub hauv paus ntawm tus nqi. Tsis yog tag nrho cov titanium hmoov sib npaug. Kev ua lag luam sib txawv ntawm qhov sib txawv raws li qhov morphology, purity, thiab qhov chaw ntawm cov hmoov.
- Spherical vs. Irregular Titanium hmoov rau Lim Elements
Titanium lim cov ntsiab lus feem ntau siv cov titanium hmoov tsis zoo, thaum lub ntsej muag titanium hmoov feem ntau yog tshwj tseg rau siab -kawg precision applications. Cov hmoov tsis sib xws peb siv, txawm li cas los xij, nyob rau hauv cov qib siab - cov kev xaiv zoo hauv khw. High-kawg precision lim tej zaum kuj siv spherical titanium hmoov uas tsim los ntawm roj atomization, ib txoj kev uas yields hais nrog siab flowability thiab zoo ib yam packing ceev thaum lub sij hawm txias isostatic pressing (CIP), uas ua rau uniform pore lug thiab ntau dua mechanical zog. Nyob rau hauv sib piv, txheem titanium lim ntsiab cia siab rau tsis xwm yeem los yog angular sponge nplua. Txawm hais tias qis dua - cov hmoov tsis zoo tuaj yeem tsim cov pore tsis sib xws thiab cov ntsiab lus kev ntxhov siab ntau ntxiv -ua kom muaj kev pheej hmoo ntawm kev tawg hauv qab ntws rov qab los yog thermal cycling -peb siab -cov titanium hmoov tsis zoo yog ua tiav los txo cov teeb meem no, xa cov txiaj ntsig zoo thiab muaj txiaj ntsig zoo rau kev pom cov ntawv thov.
- Purity thiab Qib: Rau cov ntawv thov tseem ceeb xws li biopharmaceuticals lossis semiconductor manufacturing, lub lim yuav tsum siab -purity titanium (feem ntau yog Qib 1 lossis Qib 2, nrog cov ntsiab lus tsis huv yog tswj nruj). Cov neeg muab khoom siv aerospace- qib titanium (xws li ATI lossis VSMPO cov khoom siv) tau txais cov nqi raw khoom ntau dua. Cov cuab yeej siv nyiaj siv hluav taws xob tuaj yeem siv rov ua dua titanium lossis alloys uas muaj vanadium lossis txhuas, uas, thaum lub suab nrov, yuav tsis muaj qhov tshwj xeeb corrosion kuj (tshwj xeeb hauv cov tshuaj chloride lossis acidic ib puag ncig) xav tau rau kev ua tshuaj.
- Particle Loj Distribution (PSD): Qhov sib xws ntawm particle loj faib, txhais los ntawm tsis xws li D10, D50, thiab D90, dictates qhov kawg pore loj. Qhov nqaim PSD (feem ntau qhia los ntawm X yam <2.0) yuav tsum ua kom tiav qhov ntsuas micron meej. Ua kom tiav qhov kev faib khoom nruj no yuav tsum muaj kev sib tw siab heev thiab kev faib tawm, ntxiv rau cov nqi tsim khoom.
2. Sintering txheej txheem: Atmosphere tswj thiab Isostatic nias
- Nqus vs. Atmosphere Sintering: High-kawg manufacturers siv siab- lub tshuab nqus tsev sintering furnaces (siab 10 −3 Pa lossis qis dua) los tiv thaiv oxidation thiab embrittlement ntawm titanium. Sintering titanium xav tau qhov kub thiab txias feem ntau ntawm 850℃thiab 1,200℃nyob rau hauv ib qho kev tswj inert lossis lub tshuab nqus tsev. Cov khoom lag luam qis dua -cov khoom lag luam yuav raug sintered nyob rau hauv cov huab cua tsis tshua muaj zog, ua rau oxidation ntawm qhov chaw (lub ntsej muag grey du es tsis yog xim hlau ci ci) uas tuaj yeem cuam tshuam ntev - lub sij hawm corrosion.
- Txias Isostatic Pressing (CIP): Qhov tseem ceeb tshaj plaws dhia hauv qhov zoo thiab tus nqi tshwm sim thaum cov tuam ntxhab siv CIP thev naus laus zis. CIP siv cov hydraulic siab los ntawm tag nrho cov lus qhia rau cov hmoov ua ntej sintering. Qhov no yields ib lub lim nrog uniform ntom, zoo ib yam pore loj tis, thiab siab structural kev ncaj ncees, tso cai rau pom precision mus rau 0.2 µm los yog txawm 0.1 µm. Cov ntxaij lim dej pheej yig dua feem ntau siv uniaxial nias lossis lub ntiajteb txawj nqus filling, uas ua rau cov phab ntsa tuab tsis sib xws thiab qhov dav ntawm qhov pore loj, feem ntau ua rau "tshuab- dhau" thaum lub sijhawm ua haujlwm siab -.
