Me me ceev, siab tshwj xeeb zog
Qhov ceev ntawm titanium yog 4.51g / cm3, siab dua aluminium thiab qis dua hlau, tooj liab, npib tsib xee, tab sis lub zog tshwj xeeb yog nyob rau hauv thawj cov hlau.
Corrosion kuj
Titanium yog cov hlau qhib heev, nws qhov sib npaug ntawm qhov sib txawv muaj tsawg heev, nyob rau hauv nruab nrab ntawm thermodynamic corrosion nyiam. Tab sis nyob rau hauv qhov tseeb titanium yog heev du nyob rau hauv ntau yam xov xwm, xws li titanium yog corrosion resistant nyob rau hauv oxidizing, nruab nrab thiab weakly txo cov xov xwm. Qhov no yog vim hais tias titanium thiab oxygen muaj ib tug zoo affinity, nyob rau hauv cov huab cua los yog oxygen-muaj xov xwm, titanium nto los tsim ib txheej ntawm high-density, muaj zog adhesion, plasticity ntawm oxidized zaj duab xis, txij nkawm ntawm titanium substrate yog tsis corroded. Txawm hais tias nws raug puas tsuaj los ntawm kev puas tsuaj los ntawm kev puas tsuaj, nws yuav sai sai kho lossis rov tsim dua tshiab. Qhov no qhia tau hais tias titanium raj yog hlau nrog ib tug pronounced nyiam mus passivate. Cov yam ntxwv no yog tswj hwm los ntawm oxide zaj duab xis ntawm titanium mus txog qhov kub nruab nrab ntawm 315 degree.
Txhawm rau txhim kho qhov kev tiv thaiv corrosion ntawm titanium, peb tau tsim kho cov thev naus laus zis xws li oxidation, electroplating, plasma spraying, ion nitriding, ion implantation, thiab laser kho, uas txhim kho cov nyhuv tiv thaiv ntawm titanium oxide zaj duab xis, thiab tau txais cov khoom siv. xav tau corrosion-resistant. Peb tau tsim ib tug series ntawm corrosion-resistant titanium alloys xws li titanium-molybdenum, titanium-palladium, thiab titanium-molybdenum-nickel kom tau raws li cov kev xav tau ntawm cov ntaub ntawv hlau siv nyob rau hauv zus tau tej cov hydrochloric acid, hydrochloric acid, methylamine tov, high- kub ntub chlorine roj, thiab kub-kub tshuaj chlorine. Titanium casting daim ntawv thov ntawm titanium-32 molybdenum aluminium alloy, feem ntau tsim crevice corrosion los yog pitting corrosion ib puag ncig daim ntawv thov ntawm titanium-0.3 molybdenum-0.8 nickel-based alloy lossis titanium khoom, ib feem ntawm daim ntawv thov ntawm titanium-0.2 palladium aluminium alloy, yog qhov zoo heev daim ntawv thov ntawm cov txiaj ntsig tiag.
Zoo kub tsis kam
Cov titanium alloys tshiab tuaj yeem siv tau ntev hauv qhov kub ntawm 600 degree lossis siab dua.
Zoo tsis kub tsis kam
Titanium alloys TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V) thiab Ti-2.5Zr-1 .5Co yog ultra-low-temperature titanium alloys, uas nws compressive zog nce raws li qhov kub thiab txias, tab sis cov yas transformation tsis loj. Nyob rau hauv -196-253 degree ultra-low kub kom tswj tau zoo ductility thiab ductility, tiv thaiv cov hlau txias ductility, yog ultra-low-kub hlab ntsha, cia tso tsheb hlau luam thiab lwm yam machinery thiab cov cuab yeej zoo tagnrho ntawm cov khoom.
Muaj zog tiv thaiv kev vibration
Thaum titanium hlau raug rau cov neeg kho tshuab thiab hluav taws xob kev co, nws lub sij hawm kev co decay yog ntev tshaj piv rau hlau thiab tooj liab. Cov cuab yeej ntawm titanium no tuaj yeem siv tau los ua qhov nkhaus, ultrasonic pulverizer vibration caij hauv tshuaj thiab kev co zaj duab xis ntawm cov neeg hais lus siab.
Non-magnetic, non-toxic
Titanium yog cov hlau tsis muaj hlau nplaum, nyob rau hauv cov hlau nplaum loj heev tsis yooj yim rau kev sib nqus, tsis muaj tshuaj lom thiab zoo sib xws nrog tib neeg cov ntaub so ntswg thiab ntshav hmo ntuj, yog li los ntawm kev kho mob kev xaiv.
Lub zog tensile zoo ib yam ntawm ob.
Cov cuab yeej ntawm titanium no qhia tau hais tias muaj zog flexural siab piv (lub zog tensile / tensile lub zog), uas qhia tau hais tias tsis zoo yas deformation ntawm titanium hlau thaum molding. Vim tias qhov sib piv ntawm cov txiaj ntsig txwv rau cov qauv ntawm elasticity ntawm titanium yog qhov loj, nws muab titanium muaj peev xwm loj los ua hauj lwm nrog resilience thaum molding.
Kev ua tau zoo ntawm kev hloov hluav taws xob
Txawm hais tias cov thermal conductivity ntawm titanium hlau yog qis dua li cov pa roj carbon steel thiab tooj liab, cov phab ntsa tuab tuaj yeem txo qis heev vim tias qhov zoo tshaj plaws corrosion kuj ntawm titanium, thiab cov cua kub hloov txoj kev ntawm qhov chaw thiab cov vapor yog droplet txias suspicion, uas. txo cov cua sov pab pawg, thiab cov cua sov hloov coefficient tuaj yeem txo qis los ntawm kev tsis sib sau cov nplai ntawm qhov chaw, yog li cov cua kub hloov pauv ntawm titanium tuaj yeem txhim kho tau zoo.
Tsawg modulus ntawm elasticity
Lub modulus ntawm elasticity ntawm titanium yog 106.4gMPa ntawm chav tsev kub, uas yog 57% ntawm cov hlau.
Ua tsis taus pa
Titanium yog ib hom hlau uas muaj lub cev zoo siab heev, uas tuaj yeem cuam tshuam nrog ntau lub ntsiab lus thiab tshuaj lom neeg ntawm qhov kub thiab txias. Titanium ua pa tseem ceeb hais txog qhov kub thiab txias thiab carbon, hydrogen, nitrogen, oxygen los tsim kev xav.
