Dab tsi yog Purest Titanium?

Taw qhia

Titanium yog cov hlau uas nquag siv hauv ntau qhov kev lag luam, suav nrog aerospace, khoom siv kho mob, thiab cov hniav nyiaj hniav kub. Nrog nws lub zog-rau-qhov hnyav piv, kev tiv thaiv corrosion, thiab biocompatibility, titanium yog cov khoom tseem ceeb. Tab sis dab tsi ua kom titanium ntshiab? Hauv tsab xov xwm no, peb yuav tshawb txog ntau hom titanium thiab cov yam ntxwv uas txiav txim siab lawv cov purity.

Titanium yog dab tsi?

Titanium yog cov khoom siv hlau nrog lub cim Ti thiab atomic naj npawb 22. Nws belongs rau pawg hlau hloov pauv ntawm lub rooj sib tham thiab paub txog nws lub zog, tsis tshua muaj siab, thiab siab melting point. Nws tau pom nyob rau xyoo 1791 los ntawm William Gregor, ib tug txiv plig Askiv, thiab tom qab ntawd tau muab lub npe hu ua Titans ntawm Greek mythology.

Hom ntawm Titanium

Muaj ntau ntau hom titanium, txhua tus nrog nws cov khoom thiab siv. Feem ntau hom titanium muaj xws li:

1. Kev lag luam Pure (CP) Titanium
2. Alpha Titanium Alloys
3. Nyob ze Alpha Titanium Alloys
4. Alpha-Beta Titanium Alloys
5. Beta Titanium Alloys

Kev lag luam Pure (CP) Titanium

Kev lag luam ntshiab titanium, lossis CP titanium, yog hom titanium ntau tshaj plaws thiab muaj li ntawm 99.2% titanium. CP titanium muab faib ua plaub qib, nrog Qib 1 yog qhov ntshiab tshaj plaws thiab Qib 4 yog qhov ntshiab tshaj plaws. Cov qib no txawv ntawm lawv cov pa oxygen, Qib 1 muaj cov pa oxygen tsawg thiab Qib 4 muaj ntau tshaj.

CP titanium yog siv nyob rau hauv ntau yam kev siv, xws li orthopedic implants, kho hniav implants, thiab structural Cheebtsam nyob rau hauv aircraft thiab spacecraft. Nws cov biocompatibility siab ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev cog qoob loo kho mob, thaum nws qhov tsis tshua muaj siab thiab siab zog-rau-qhov hnyav piv ua rau nws muaj txiaj ntsig hauv kev siv aerospace.

Alpha Titanium Alloys

Alpha titanium alloys tsuas muaj alpha-theem titanium xwb, uas yog theem ruaj khov ntawm chav tsev kub. Cov alloys no muaj lub zog zoo thiab ductility, nrog rau zoo heev corrosion kuj. Alpha titanium alloys yog siv nyob rau hauv daim ntaub ntawv uas corrosion kuj yog ib qho tseem ceeb, xws li cov khoom siv tshuaj thiab marine Cheebtsam.

Nyob ze Alpha Titanium Alloys

Nyob ze alpha titanium alloys muaj kev sib xyaw ntawm alpha-theem thiab beta-phase titanium. Cov alloys no muaj cov khoom zoo txhua yam ntawm ob qho tib si qis thiab siab kub, thiab zoo heev corrosion kuj. Nyob ze alpha titanium alloys yog siv rau hauv daim ntawv thov uas yuav tsum tau muaj zog thiab toughness, xws li roj turbines thiab aircraft engine Cheebtsam.

Alpha-Beta Titanium Alloys

Alpha-beta titanium alloys muaj alpha-phase thiab beta-phase titanium. Cov alloys no muaj kev sib xyaw ua ke ntawm lub zog siab, ductility, thiab toughness, nrog rau zoo heev corrosion kuj. Alpha-beta titanium alloys yog siv rau hauv ntau yam kev siv, nrog rau cov khoom siv dav hlau thiab cov khoom siv dav hlau, cov koom haum ntaus golf, thiab cov khoom siv phais.

Tom ntej: Beta Titanium Alloys

Beta titanium alloys tsuas muaj beta-theem titanium, uas muaj lub zog siab thiab qhov ntom ntom. Cov alloys no muaj cov khoom zoo txhua yam ntawm ob qho tib si qis thiab siab kub, thiab zoo heev corrosion kuj. Beta titanium alloys yog siv rau hauv cov ntawv thov uas xav tau lub zog siab thiab lub teeb, xws li cov khoom siv dav hlau thiab cov khoom ua si.

Cov yam ntxwv uas txiav txim siab Titanium Purity

Lub purity ntawm titanium yog txiav txim los ntawm ntau yam, xws li:

1. Cov ntsiab lus Oxygen: Oxygen yog cov impurity feem ntau hauv titanium thiab tuaj yeem cuam tshuam rau nws cov khoom siv kho tshuab. Cov ntsiab lus ntawm cov pa oxygen hauv titanium yog ntsuas nyob rau hauv qhov chaw ib lab (ppm), nrog rau qib qis qhia tias muaj kev purity ntau dua.
2. Nitrogen Cov ntsiab lus: Nitrogen yog lwm yam impurity hauv titanium uas tuaj yeem cuam tshuam rau nws cov khoom siv kho tshuab. Cov ntsiab lus nitrogen hauv titanium kuj tau ntsuas hauv qhov chaw ib lab (ppm), nrog rau qib qis qhia tias muaj purity ntau dua.
3. Cov ntsiab lus carbon: Cov pa roj carbon monoxide yog qhov tsis zoo hauv titanium uas tuaj yeem cuam tshuam rau nws cov khoom siv kho tshuab, tshwj xeeb tshaj yog nws cov ductility. Cov ntsiab lus carbon hauv titanium feem ntau ntsuas hauv qhov hnyav feem pua ​​(wt%), nrog cov qib qis qhia tias muaj purity ntau dua.
4. Lwm yam impurities: Lwm yam impurities, xws li hydrogen, hlau, thiab npib tsib xee, kuj tuaj yeem cuam tshuam rau titanium's mechanical zog. Cov impurities no feem ntau ntsuas nyob rau hauv qhov chaw ib lab (ppm), nrog rau theem qis qhia tias muaj kev purity siab dua.

Xaus

Hauv kev xaus, purity ntawm titanium yog txiav txim los ntawm ntau yam, nrog rau nws cov pa oxygen, nitrogen, thiab cov ntsiab lus carbon, nrog rau muaj lwm yam impurities. Kev lag luam ntshiab titanium yog hom titanium tshaj plaws, thaum lwm hom titanium, xws li alpha, ze alpha, alpha-beta, thiab beta titanium alloys, yog siv nyob rau hauv ntau daim ntawv thov raws li lawv cov khoom. Raws li ib qho ntawm cov hlau tseem ceeb tshaj plaws, titanium tseem yog cov khoom tseem ceeb hauv ntau qhov kev lag luam vim nws lub zog, hnav, thiab corrosion kuj.
