ASTM F67 Gr2 titanium ntawv

Biocompatibility: tsim nyog siv rau hauv tib neeg implants raws li nws tsis tshua muaj tshwm sim tsis zoo tshwm sim thiab yog sib xws nrog tib neeg cov ntaub so ntswg.
Corrosion kuj: nws qhia tau hais tias zoo heev tiv thaiv corrosion nyob rau hauv ib tug ntau yam ntawm ib puag ncig, nrog rau cov seawater thiab feem ntau acid thiab alkali daws.
Qhov sib npaug ntawm lub zog thiab lub zog: txawm hais tias cov titanium ntshiab, nws tseem khaws cov khoom zoo tag nrho rau cov ntawv thov uas xav tau qee qib ntawm lub zog thiab zoo plasticity.
Tsawg ntom ntom: qis dua cov hlau thiab ntau lwm yam hlau, haum rau qhov xav tau qhov hnyav.

1. Raw khoom npaj: High purity titanium raw cov ntaub ntawv raug xaiv los xyuas kom meej lub purity thiab cov khoom ntawm cov khoom kawg.
2. Smelting: Tshem tawm impurities los ntawm raw khoom thiab xyuas kom meej cov tshuaj muaj pes tsawg leeg raws li tus qauv los ntawm Nqus Arc tshem tawm (VAR) los yog lwm yam advanced melting hom kev kawm.
3. Forging / Rolling: Tom qab melting, titanium ingot yog forged los yog kub dov ob peb zaug los tsim cov thickness thiab loj ntawm daim ntawv, thaum nws microstructure yog optimized los ntawm kev kho cua sov.
4. annealing: txhawm rau tshem tawm cov kev ntxhov siab sab hauv thiab txhim kho cov yas thiab tawv ntawm cov khoom, cov phaj feem ntau yog annealed.
5. machining: raws li qhov xav tau, lub phaj yog mechanically ua tiav los ntawm kev txiav, stamping, drilling, thiab lwm yam kom ua tiav qhov loj thiab cov duab ntawm cov khoom kawg.
