Kev loj hlob ntawmtitanium hlaupib thaum xyoo 1940s nrog rau kev tsim kho ntawm Kroll txheej txheem, uas tau ua kom loj - nplai titanium ntau lawm. Vim nws tus nqi siab thaum lub sijhawm, titanium hlau tau pib txwv rau kev siv dav hlau thiab tub rog, suav nrog cov fasteners thiab siab - lub zog ntawm cov khoom siv.

Nyob rau xyoo 1970, NiTi hlau hlau nkag mus rau hauv orthodontic teb, nthuav cov titanium-raws li cov ntaub ntawv rau hauv daim ntawv thov kev kho mob vim nws cov duab nco thiab superelastic zog.

Txij li thaum xyoo 1980s, kev tsim cov txheej txheem titanium ua cov txheej txheem tau ua kom muaj kev siv ntau dua. Niaj hnub no, titanium hlau yog dav siv nyob rau hauv kev kho mob implants, cov neeg siv khoom, thiab advanced manufacturing, nrog rau cov hlau -raws li additive manufacturing technologies.

titanium hlau yog tsim los ntawm kev tswj cov txheej txheem tsim khoom. Titanium ingots yog thawj zaug tsim los ntawm lub tshuab nqus tsev melting kom ntseeg tau cov tshuaj sib xws. Tom qab ntawd lawv tau ua tiav los ntawm kev sib tsoo, dov, thiab ntau- theem kev kos duab kom maj mam txo txoj kab uas hla thiab ua tiav cov kev xav tau ntawm cov xov hlau.

Los ntawm Hom Khoom

Kev lag luam Pure Titanium Hlau(Qib 1, Qib 2, Qib 3)
Nrog cov ntsiab lus titanium Ntau dua lossis sib npaug li 99.5%, cov khoom lag luam ntshiab titanium xaim muaj kev tiv thaiv zoo heev thiab kev tsim kho. Nws yog qhov zoo tagnrho rau thaj chaw marine thiab kev siv tshuaj lom neeg.

• Minimally invasive phais xov hlau:

Corrosion tus nqi qis dua 0.01 hli / xyoo hauv cov kua dej hauv lub cev ua rau lub neej ua haujlwm ntev.

3. Kev lag luam tshuaj lom neeg

Titanium hlau yog dav siv nyob rau hauv cov tshuaj lom neeg nruj heev qhov chaw uas corrosion kuj tseem ceeb heev.

• Kev sib txuas ntawm electrolyzer:

Anodized titanium hlau ho txhim kho chlorine corrosion kuj thiab txuas ntxiv lub neej kev pab cuam nyob rau hauv acidic ib puag ncig, muab ib tug nqi - zoo lwm txoj rau platinum.

• Reactor Cheebtsam:

Titanium alloy shafts (5-10 hli, Ntau dua lossis sib npaug ntawm 895 MPa) muab kev ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias.

• Cov tshuab lim dej:

Titanium mesh nrog ± 0.02 hli precision zoo lim cov khoom loj dua 5 μm hauv cov txheej txheem tshuaj zoo.

 

4. Cov khoom siv hluav taws xob thiab cov khoom siv precision

Titanium hlau yog zoo tagnrho rau siab -precision thiab nqus daim ntaub ntawv.

• Lub tshuab nqus tsev electrode:
