Titanium alloys muaj ob peb yam ntxwv, nrog rau tsis tshua muaj hardness, siab zog, zoo heev corrosion kuj, siab kub tsis kam, thiab lub teeb yuag zog. Cov cwj pwm no ua rau cov titanium alloys tsis tsim nyog rau cov ntawv thov uas xav tau siab hardness, xws li cov ntaub ntawv ntug.
1. Siab zog:
Titanium alloy muaj qhov ntom ntom ntawm 4.5g / cm3, uas tsuas yog 60% ntawm cov hlau. Txawm hais tias nws qis ntom ntom, lub zog ntawm ntshiab titanium yog sib piv rau cov hlau loj, thiab qee qhov siab tshaj plaws titanium alloys txawm muaj ntau lub zog ntawm cov qauv hlau. Raws li qhov tshwm sim, titanium alloys pom muaj lub zog tshwj xeeb (lub zog / ntom), ua rau lawv zoo tagnrho rau kev tsim cov khoom sib sib zog nqus nrog lub zog siab, rigidity, thiab lub zog. Cov khoom siv dav hlau dav hlau, cov pob txha, tawv, fasteners, thiab tsaws iav feem ntau siv cov titanium alloys.
2. Siab Thermal Strength:
Titanium alloys tuaj yeem tiv taus qhov kub thiab txias dua li aluminium alloys. Lawv tuaj yeem tuav lawv lub zog xav tau txawm tias nyob hauv nruab nrab qhov kub thiab muaj zog tshaj ntawm 150 degree thiab 500 degree, thaum aluminium alloys muaj kev poob qis hauv lub zog ntawm 150 degree. Titanium alloys tuaj yeem ua haujlwm ntawm qhov kub txog li 500 degree, whereas aluminium alloys txwv rau kub hauv qab 200 degree.
3. Zoo Corrosion Resistance:
Titanium alloys ua haujlwm zoo dua stainless hlau hauv cov huab cua ntub thiab dej hiav txwv. Lawv muaj kev tiv thaiv zoo heev rau pitting, acid corrosion, thiab kev nyuaj siab corrosion. Titanium alloys kuj pom zoo heev corrosion kuj rau alkalis, chlorides, chlorine organic tshuaj, nitric acid, thiab sulfuric acid, thiab lwm yam. Txawm li cas los xij, titanium tsis kam tiv thaiv corrosion hauv kev txo qhov chaw thiab chromium ntsev media tsis zoo.
4. Kev ua tau zoo ntawm qhov kub thiab txias:
Titanium alloys tswj lawv cov khoom siv kho tshuab hauv qhov kub thiab txias txias. Qee cov titanium alloys, xws li TA7, khaws ib qib ntawm plasticity txawm nyob rau ntawm -253 degree . Yog li ntawd, titanium alloys yog cov ntaub ntawv tseem ceeb rau kev siv qis-kub.
5. Chemical Activity:
Titanium nthuav tawm cov tshuaj lom neeg ua haujlwm siab thiab tuaj yeem ua rau cov pa hauv huab cua xws li oxygen, nitrogen, hydrogen, carbon monoxide, carbon dioxide, dej vapor, thiab ammonia. Cov ntsiab lus carbon siab dua hauv titanium alloys tuaj yeem tsim cov tawv titanium carbide (TiC). Titanium kuj reacts nrog nitrogen los tsim ib txheej txheej tawv ntawm titanium nitride (TiN) ntawm qhov kub siab. Thaum kub siab tshaj 600 degree, titanium absorbs oxygen los tsim ib txheej hardened nrog siab hardness. Absorption ntawm gases yuav ua rau ib tug nkig txheej txheej. Titanium kuj tseem muaj cov tshuaj lom neeg tseem ceeb, ua rau muaj qhov tshwm sim adhesion ntawm kev sib txhuam.
6. Tsawg Thermal Conductivity thiab Modulus ntawm Elasticity:
Lub thermal conductivity ntawm titanium yog qis dua piv rau npib tsib xee, hlau, thiab txhuas. Titanium alloy khoom muaj kwv yees li 1/4 lub thermal conductivity ntawm npib tsib xee, 1/5 ntawm hlau, thiab 1/14 ntawm txhuas. Lub thermal conductivity ntawm ntau yam titanium alloys yog li 50% qis dua li ntawm cov ntshiab titanium. Lub modulus ntawm elasticity ntawm titanium alloys yog kwv yees li ib nrab ntawm cov hlau, uas ua rau qis rigidity thiab nce susceptibility rau deformation. Qhov no ua rau cov titanium alloys tsis haum rau cov pas nrig, nyias-walled qhov chaw, thiab cov txheej txheem txiav, raws li lawv nthuav tawm qhov tseem ceeb ntawm qhov chaw, ua rau muaj kev sib txhuam, adhesion, thiab kev sib txuas ntawm cov cuab yeej siv.
