Titanium Disc

Titanium Disc yog dab tsi?

Titanium discyog ib qho ze-type titanium alloy, nws cov nominal muaj pes tsawg leeg yog Ti-6Al-2Sn-4Zr-2Mo(Ti6242), muaj cov khoom ruaj khov Al, cov ntsiab lus nruab nrab Sn thiab Zr, isomorphic ruaj khov caij Mo, eutectoid Stable caij Si.

Titanium Disc nrog ntau yam ntaub ntawv nanoscale npaj siv sol-gel-txheej txheej txheej, tshwj xeeb tshaj yog anatase, rutile, zirconia, thiab tshwj xeeb tshaj yog alumina, nthuav cov ntsiab lus ntawm osteogenic cov cim phosphatase, pob txha sialoprotein, osteocalcin, osteoprotegerin, osterix, thiab ib nrab-pint cov ntaub ntawv ntsig txog. yam 2 (Runx-2) nyob rau hauv tib neeg mesenchymal tsis paub tab microorganisms contrasted nrog tswj Ti nto kho los ntawm machining thiab corrosive kos duab.

Nws siv lub tswv yim potentiostatic: lub davhlau ya nyob twg ua los ntawm kev txhim kho ntawm cov hlau phaj (los yog Titanium Disc rau cov dej ntsev) yog spellbound ntawm ib tug zoo cathodic peev xwm, hais txog ib tug indistinguishable tempered steel anode, rau ib teev txhua hnub. Qhov seem tam sim no, uas yog ntsuas txhua txhua 10 feeb thoob plaws hnub so thaum lub polarization sab nraud raug kaw, yog siv los ua qhov taw qhia ntawm kev loj hlob ntawm biofilm ntawm qhov chaw sojntsuam thaum qhov tshwm sim tam sim no mus txog qhov poob qis ntawm qhov ob electrodes.

Lub TA19 alloy muaj lub zog siab txog 540 degree, tshaj TA11 alloy. Nws lub zog tshwj xeeb yog qhov zoo tshaj plaws ntawm TA14 alloy, thiab nws qhov kev ua tau zoo yog zoo dua li ntawm TA11 alloy, uas yog sib npaug ntawm TA14 alloy.

TA19 titanium alloy kub kho qhov system

1) Ob chav annealing

Bars thiab forgings: 970 degree, 1h, cua txias ntxiv rau 595 degree, 8h, cua txias; daim hlau: 900 degree, 10-30min, cua txias ntxiv rau 790 degree, 15min, cua txias.

2) triple annealing (phaj)

900 degree , 10-30min, cua txias ntxiv rau 790 degree, 15min, cua txias ntxiv 595 degree, 2h, cua txias.

3) Kev ntxhov siab ntxhov siab annealing

480-650 degree , 1-4h, cua txias lossis cua sov cua txias.

4) Ordinary annealing (casting)

700-800 degree , 1-2h, cua txias lossis cua sov cua txias.

5) Kub isostatic nias (casting)

900 ± 10 degree , 100-110MPa, 2h, txias kom qis dua 250 degree nrog rau qhov cub.

6) Kev ntxhov siab nyem annealing (casting)

580-620 degree , 1-2h, cua txias lossis cua sov cua txias.

Daim ntawv thov titanium disc

Nws tau raug siv los tsim cov tshuab aero-engine compressor casings hauv kuv lub tebchaws. Lub titanium txiav disc tseem muaj qhov zoo thermal stability tom qab 1000h kub raug ntawm 540 degree.

TA19 alloy muaj corrosion kuj zoo. Txawm li cas los xij, kuj tseem muaj qee qhov rhiab heev rau kev kub ntsev kev ntxhov siab corrosion, thiab muaj qhov ncua sij hawm tawg hauv qhov kev sim tawg hauv chav-kub ntsev ntsev ib puag ncig. Cov alloy no muaj kev nkag siab ntau dua rau ntsev kev nyuaj siab dua li TA14 alloy, tab sis tsawg dua TC4, TA11 thiab TA7 alloys.

Titanium discs muaj Al thiab Sn, muaj cov khoom zoo casting, yooj yim rau kev tsim, thiab tsis muaj kev nyiam kub tawg. Tshwj xeeb-zoo li tus castings ntawm ntau yam duab, qhov ntau thiab tsawg, thiab phab ntsa thicknesses yuav cam khwb cia rau hauv pwm tsim rau casting titanium alloys.
