Titanium alloys muaj ntau yam zoo, nrog rau lub teeb yuag, lub zog siab, kev tiv thaiv corrosion, kev ua haujlwm kub tsis zoo, thiab kev ua haujlwm siab. Tsis tas li ntawd, lawv muaj kev qaug zog ua haujlwm zoo, ua kom tsis muaj zog, siab kub lub zog, biocompatibility, thermal conductivity zoo, thiab cov khoom tsis sib nqus. Kev sib txawv ntawm cov titanium alloys tuaj yeem ua tau raws li ntau yam kev thov, ua rau lawv siv dav hauv aerospace, tsheb, kho mob, tshuaj, thiab lwm yam lag luam.
Kev ua tau zoo ntawm titanium alloys:
Exceptional zog
Titanium alloys muaj qhov ntom ntawm kwv yees li 4.5g / cm3, uas tsuas yog 60% ntawm cov hlau. Ntshiab titanium muaj lub zog piv rau cov hlau zoo tib yam, thaum qee qhov muaj zog titanium alloys tshaj lub zog ntawm ntau cov hlau hlau hlau. Yog li ntawd, titanium alloys muaj lub zog tshwj xeeb (lub zog / qhov sib piv), ua rau lawv zoo tagnrho rau cov khoom hnyav nrog lub zog siab, rigidity, thiab durability. Cov alloys no pom cov ntawv thov hauv cov khoom siv cav, pob txha, tawv nqaij, fasteners, thiab tsaws iav.
Superior Thermal Resistance
Titanium alloys tuaj yeem tiv taus qhov kub thiab txias dua li aluminium alloys, tswj lawv lub zog txawm tias kub siab. Qee cov titanium alloys tuaj yeem ua haujlwm rau lub sijhawm ntev ntawm qhov kub thiab txias xws li 450-500 degree, qhia lub zog tshwj xeeb hauv qhov kub ntawm 150 degree -500 degree . Hauv qhov sib piv, aluminium alloys muaj kev txo qis hauv lub zog tshwj xeeb ntawm 150 degree. Nrog lub siab tshaj plaws kev khiav hauj lwm kub ntawm 500 degree, titanium alloys outperform txhuas alloys, uas muaj ib tug txwv ntawm qis dua 200 degree.
Zoo heev Corrosion Resistance
Thaum ua haujlwm hauv cov huab cua ntub lossis dej hiav txwv ib puag ncig, titanium alloys pom zoo corrosion kuj piv rau stainless hlau. Lawv ua tau zoo kawg nkaus tiv thaiv pitting corrosion, acid corrosion, thiab kev nyuaj siab corrosion. Titanium alloys kuj pom zoo tiv thaiv alkalis, chlorides, chlorinated organic tshuaj, nitric acid, thiab sulfuric acid. Txawm li cas los xij, lawv muaj kev txwv tsis pub txo cov neeg ua haujlwm, oxygen, thiab chromium ntsev media.
Impressive Low-Temperature Performance
Titanium alloys khaws cov yam ntxwv ntawm cov neeg kho tshuab thaum tsis tshua muaj kub thiab ultra-tsawg kub. Qee cov titanium alloys, xws li TA7, muaj qhov ua tau zoo ntawm qhov kub thiab txias thiab tswj tau qee theem ntawm plasticity ntawm -253 degree . Yog li, titanium alloys yog cov khoom siv tseem ceeb rau kev siv hauv qhov chaw qis qis.
Tshuaj Reactivity siab
Titanium muaj cov tshuaj lom neeg tseem ceeb, nkag mus rau cov tshuaj tiv thaiv nrog cov ntsiab lus xws li oxygen, nitrogen, hydrogen, carbon monoxide, carbon dioxide, dej vapor, thiab ammonia gas. Piv txwv li, titanium alloys uas muaj cov ntsiab lus carbon ntau tshaj {{0}}.2% tsim tawv titanium carbide (TiC). Thaum kub siab dua, titanium reacts nrog nitrogen los tsim ib txheej txheej tawv tawv ntawm titanium nitride (TiN). Titanium absorbs oxygen ntawm qhov kub siab tshaj 600 degree, tsim ib txheej hardening nrog siab hardness. Ntxiv cov ntsiab lus hydrogen ua rau tsim cov txheej txheem embrittlement. Cov roj uas nqus tau tuaj yeem tsim cov txheej txheej tawv thiab tawv tawv nrog qhov tob ntawm 0.1-0.15mm, ua rau muaj kev sib txhuam ntau ntxiv, adhesion, thiab hnav ntawm qhov chaw sib cuag.
Tsawg Thermal Conductivity thiab Elastic Modulus
Titanium alloys pom cov thermal conductivity qis dua piv rau npib tsib xee, hlau, thiab txhuas. Lub thermal conductivity ntawm titanium alloy khoom yog kwv yees li 1/4 ntawm nickel, 1/5 ntawm hlau, thiab 1/14 ntawm txhuas. Tsis tas li ntawd, thermal conductivity ntawm ntau yam titanium alloys yog li 50% qis dua li ntawm cov ntshiab titanium. Lub elastic modulus ntawm titanium alloys yog kwv yees li ib nrab ntawm cov hlau, uas ua rau qis rigidity. Yog li ntawd, titanium alloys raug cuam tshuam rau deformation thiab tsis haum rau tsim cov pas nrig los yog nyias-walled qhov chaw. Thaum lub sij hawm txiav cov txheej txheem, titanium alloys nthuav tawm ntau dua nto rebound ntim piv rau stainless hlau, ua rau muaj kev sib txhuam, adhesion, thiab hnav ntawm lub cuab yeej nto.
