2. Kev faib tawm ntawm cov khoom siv titanium

Cov ntaub ntawv titanium tuaj yeem muab faib ua ntau hom raws li lawv qhov muaj pes tsawg leeg, qauv, thiab cov khoom

1) Muaj cov ntshiab titanium: hais txog cov ntshiab titanium yam tsis tau ntxiv cov ntsiab lus alloying, uas muaj corrosion kuj zoo heev thiab zoo plasticity.

2) Titanium alloy: Los ntawm kev ntxiv lwm yam alloying ntsiab xws li txhuas, vanadium, chromium, npib tsib xee, molybdenum, thiab lwm yam., cov yam ntxwv ntawm titanium tuaj yeem hloov tau raws li qhov xav tau ntawm ntau daim ntawv thov. Titanium alloys tuaj yeem muab faib ua alpha hom titanium alloys, beta hom titanium alloys, alpha + beta hom titanium alloys, thiab lwm yam raws li hom thiab cov ntsiab lus ntawm alloying ntsiab.

 

3. Kev npaj cov khoom siv titanium

Cov txheej txheem kev npaj ntawm cov ntaub ntawv titanium feem ntau suav nrog cov kauj ruam hauv qab no:

1) Smelting: nqa tawm nyob rau hauv lub tshuab nqus tsev lossis inert cua kom tsis txhob muaj kev cuam tshuam ntawm titanium thiab cov khoom xws li oxygen thiab nitrogen hauv huab cua.

2) Casting: Ncuav cov kua titanium melted rau hauv pwm thiab txias kom tau titanium castings.

3) Forging: Cua sov thiab siv lub siab rau cov khoom siv titanium los ntxias cov yas deformation, thiaj li tau txais cov duab thiab qhov loj me.

4) Rolling: Rolling titanium cov ntaub ntawv los ntawm lub tshuab dov kom tau txais cov phaj xav tau, strips, thiab lwm yam.

5) Pulling: Rub cov ntaub ntawv titanium los ntawm lub tshuab kos duab kom tau txais cov xov hlau uas xav tau, cov kav dej, thiab lwm yam.

 

4. Kev siv thaj chaw ntawm cov khoom siv titanium

Titanium cov ntaub ntawv yog dav siv nyob rau hauv ntau lub teb vim lawv cov kev ua tau zoo heev:

1) Aerospace: Siv rau kev tsim cov khoom tseem ceeb ntawm lub dav hlau, foob pob hluav taws, thiab lwm yam khoom siv dav hlau, xws li cov hniav, lub cev, thiab lwm yam.

2) Dej hiav txwv engineering: siv rau kev tsim cov khoom tsim thiab cov kav dej rau cov chaw sab nrauv, cov nkoj, nrog rau cov kav dej drilling thiab cov khoom siv tiv thaiv corrosion hauv offshore roj thiab roj tsim.

3) Biomedical: Siv rau kev tsim cov khoom siv kho mob xws li cov pob qij txha thiab cov hniav cog hniav, nrog rau cov cuab yeej phais thiab cov cuab yeej pabcuam.

4) Chemical metallurgy: siv rau kev tsim khoom xws li reactors, distillation towers, pipelines, thiab lwm yam hauv cov khoom siv tshuaj, nrog rau cov electrodes, crucibles, thiab lwm yam hauv metallurgical khoom.

5) Hluav taws xob: Siv los tsim cov khoom siv hluav taws xob xws li condensers, blades rau chav turbines, thiab generator rings.

6) Architecture: Siv los ua cov khoom siv kho kom zoo nkauj xws li cov ntaub thaiv phab ntsa thiab lub ru tsev, nrog rau cov khoom siv xws li txuas hniav thiab qhov.

7) Leisure: Siv los ua cov khoom ua si xws li golf taub hau thiab lub tsheb kauj vab.

5. Kev lag luam zeem muag ntawm cov ntaub ntawv titanium

Nrog kev txhim kho txuas ntxiv ntawm kev lag luam thoob ntiaj teb thiab kev nce qib hauv kev siv thev naus laus zis, daim ntawv thov kev lag luam ntawm titanium cov ntaub ntawv yuav dhau los ua ntau dua. Tshwj xeeb tshaj yog nyob rau hauv high-end teb xws li aerospace, dej hiav txwv engineering, thiab biomedicine, qhov kev thov rau titanium cov ntaub ntawv yuav loj hlob ntxiv. Lub caij no, nrog kev nce ntxiv ntawm kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov, titanium, raws li cov khoom siv ntsuab thiab ib puag ncig zoo, yuav tau txais kev saib xyuas ntau dua thiab nyiam. Yog li ntawd, kev lag luam kev cia siab rau cov ntaub ntawv titanium yog dav heev.

 

Kev siv dav dav ntawm cov ntaub ntawv titanium qhia txog nws tus nqi hauv ntau yam kev lag luam. Nrog rau kev nce qib ntawm cov thev naus laus zis, qhov kev thov rau cov khoom siv titanium nce zuj zus ib hnub dhau ib hnub, thiab nws cov ntawv thov yav tom ntej hauv ntau txoj haujlwm tshiab kuj tseem tsim nyog tos ntsoov rau. Titanium tsis yog hlau xwb, nws sawv cev rau cov kev taw qhia thiab muaj peev xwm ntawm kev tsim kho kev lag luam.
