Khoom Taw Qhia
Titanium substrate yog ib qho hlau platform nyob rau hauv cov khoom siv ua haujlwm ntawm cov khoom siv hlau ntxiv, xws li laser hmoov melted lpbf thiab hluav taws xob ci melting ebm. Nws yog lub hauv paus ntawm lub cev ntawm cov txheej txheem luam ntawv, qhov twg thawj txheej ntawm cov hlau nplaum los ntawm txheej txheem ntawm qhov no, thaum kawg ua ib qho - qhov ntev.
Cov Ntsiab Lus Tseem Ceeb
Thermal Stability: muaj peev xwm tiv thaiv cov kev kub siab ntau dua lossis sib npaug ntawm 1000℃li 1000℃li 1000 degree, nrog rau cov khoom siv hluav taws xob uas phim cov khoom luam tawm (xws li ti-6al-4V);
Kev qaug zog tiv: Lub sijhawm pabcuam hauv qab cyclic thauj khoom yog ntau dua 5000 teev, zam kev tawg tshwm sim los ntawm kev ntxhov siab;
Interface sib haum: nto roughness ra tsawg dua los yog sib npaug rau 3.2 μ m, ua kom tiav thawj txheej luam ntawv cov khoom noj;
Kev Tsim Khaub Ncaws Hnav: Composite qauv txo tus nqi txo qhov hnyav los ntawm ntau dua 30%.
Qauv nta
Feem ntau nws yog daim ntawv tuab lossis lub phaj tuab)
Qhov saum npoo
Sab nraub qaum feem ntau muaj kev teeb tsa interfaces (xws li threaded qhov, daim npav slots) rau kev kho ntawm cov khoom siv ua haujlwm.
Lub substrate yog feem ntau xav tias muaj kev siv lossis semi muaj kev pab. Tom qab luam ntawv tiav, cov seem yuav tsum tau txiav thiab sib cais los ntawm cov txheej txheem (xaim txiav, thiab lwm yam) tuaj yeem ua rau puas tsuaj rau sab nraud. Tom qab ob peb txiav thiab cov khoom kho qub (re milling), lub substrate tau raug kaw vim tsis muaj tuab.
