Kaum lub zog ntawm titanium
Nyob rau hauv txoj kev loj hlob ntawm tib neeg kev vam meej, cov ntaub ntawv kev tshawb fawb yeej ib txwm yog ib tug tseem ceeb engine rau kev vam meej technology. Ntawm cov pab pawg hlau, titanium tsev neeg sawv ib leeg rau nws qhov kev ua tau zoo, qhuas "immortal hlau". Kab lus no yuav coj koj mus txog lub sijhawm los tshawb txog keeb kwm, keeb kwm thiab kaum tus yam ntxwv tshwj xeeb ntawm Tau.
Keeb kwm thiab keeb kwm
Cov ntaub ntawv ntxov tshaj plaws ntawm titanium hnub rov qab mus rau xyoo pua 18th, tab sis nws tsis tau lees paub los ntawm tib neeg kom txog rau thaum xyoo pua 20th. Nyob rau hauv 1801, British chemist Gregor nrhiav tau lub hav zoov ntawm titanium nyob rau hauv ib tug ore. Nws tsis yog txog xyoo 1932 uas Kroll tau ua tiav cov titanium rau hauv daim ntawv hlau. Cov txheej txheem no zoo li tus alchemist lub incantation, hloov cov ntsiab lus tsis meej rau hauv "kub tsis txawj tuag" uas tau siv dav tom qab.
Kaum tus yam ntxwv tseem ceeb
1. Lub zog hnyav:
Lub cubic ntom ntawm titanium yog 4.5 g / cm2, uas yog ze li ib nrab sib zog dua cov hlau, tab sis nws muaj zog heev. Lub teeb thiab muaj zog tus yam ntxwv no ua rau titanium cov khoom ntawm kev xaiv nyob rau hauv lub teb ntawm qhov chaw tshawb nrhiav thiab aerospace, muab tib neeg sib dua tis rau lawv npau suav ntawm ya.
2. Corrosion thiab oxidation kuj:
Titanium tuaj yeem ua kom nws qhov chaw huv si thiab tsis muaj xeb thiab xeb hauv qhov chaw huab cua xws li cov kua qaub, muaj zog alkali thiab dej hiav txwv. Qhov no ua rau titanium yog qhov kev xaiv zoo tshaj plaws rau marine engineering, khoom siv tshuaj lom neeg thiab lwm yam kev lag luam, ua rau tib neeg mus rau qhov chaw siab tawv.
3. Biocompatibility:
Lub titanium nto muaj biocompatibility zoo heev thiab tsis zoo li yuav ua rau muaj kev tiv thaiv kab mob hauv tib neeg lub cev. Yog li ntawd, hauv kev kho mob, titanium tau pom dav dav hauv cov pob qij txha, cov khoom cog thiab lwm yam khoom siv kho mob, thiab tau ua haujlwm zoo rau tib neeg kev noj qab haus huv.
4. Kub kub kuj:
Titanium muaj cov ntsiab lus melting siab txog 1668 thiab muaj qhov kub thiab txias ua haujlwm. Qhov no tso cai rau titanium ua tau zoo nyob rau hauv qhov kub-kub ib puag ncig xws li aerospace xyaw thiab tshuaj reactors, thiab nws tau tiv thaiv tib neeg txoj kev tshawb nrhiav tsis tu ncua ntawm kev txwv.
5. Thermal conductivity:
Txawm hais tias tsis zoo li tooj liab, txhuas thiab lwm yam hlau, thermal conductivity ntawm titanium tseem yog qhov tseem ceeb. Qhov no ua rau titanium yog ib qho kev xaiv zoo tshaj plaws thaum ua cov khoom uas tsis tas yuav tsum tau ntxim hlub thermal conductivity.
6. Plasticity:
Titanium muaj cov txheej txheem zoo heev thiab tuaj yeem ua rau ntau yam duab los ntawm kev ua haujlwm txias thiab kub. Qhov no ua rau titanium tsis yog tsuas yog tsim ntau yam qauv, tab sis kuj tsim cov duab tshwj xeeb, muab qhov chaw zoo dua rau kev ua kom zoo nkauj.
7. Ib puag ncig tus phooj ywg thiab rov ua dua tshiab:
Titanium muaj cov khoom zoo dua qub thiab tuaj yeem rov qab los thiab rov siv dua los txo qis kev siv ntau dhau ntawm cov peev txheej ntuj. Raws li lub tswv yim ntawm kev txhim kho kom ruaj khov, titanium cov khoom zoo ib puag ncig zoo txhim kho nws cov tsos.
8.Zoo hluav taws xob conductivity:
Piv nrog rau lwm yam khoom siv, titanium nthuav tawm cov khoom siv hluav taws xob zoo dua, uas ua rau nws siv ntau dua hauv kev siv hluav taws xob. Hauv cov khoom siv hluav taws xob, titanium's waveform lus qhia.
9. Zoo heev bendability:
Titanium muaj cov cuab yeej khoov zoo heev thiab tuaj yeem tiv thaiv kev khoov deformation los ntawm sab nraud quab yuam hauv qee cov txheej txheem. Qhov no ua rau titanium ua lub luag haujlwm loj hauv qee qhov xwm txheej uas yuav tsum tau khoov thiab tis dabtsi yog khoov, xws li lub dav hlau thiab lub cev tsheb.
10.Aesthetic tus nqi:
Lub ntuj hlau iav ntawm titanium nto thiab nws cov yas zoo ua rau cov khoom siv titanium nrhiav tau zoo heev hauv kev tsim qauv. Los ntawm high-end watches mus rau khoom kim heev khoom kim heev, titanium tau qhia infinite aesthetic ntxim nyiam.
Cov ntsiab lus
Titanium, cov hlau tej yam yees siv no los ntawm qhov tob ntawm lub ntiaj teb, tau maj mam tsim cov khoom siv lub cev thiab ntau yam kev siv, ua lub hauv paus ntawm kev lag luam niaj hnub thiab thev naus laus zis. Nws tsis yog tsuas yog nqa cov kev tshawb fawb ntawm tib neeg kev txwv, tab sis kuj tshawb fawb hauv tshuaj, tshuaj lom neeg kev lag luam, aerospace thiab lwm yam kev lag luam. Zoo ib yam li nws tus cwj pwm tawv, titanium hlau tau sau cov lus dab neeg tsis txawj tuag nyob rau hauv keeb kwm ntev ntawm tib neeg kev vam meej.
