GR5 Titanium Alloy: Daim Ntawv Thov Scope thiab Cov Khoom

GR5 titanium alloy tseem hu ua TC4 titanium alloy, thiab feem ntau hu ua Ti-6Al-4V. Nws yog feem ntau siv titanium hlau, thiab lo lus "titanium alloy" feem ntau yog hais txog qib no. Nws muaj lub zog zoo thiab elongation.

Titanium thiab nws cov alloys paub txog ntau yam zoo heev xws li qhov hnyav, siab zog, muaj zog kub tsis kam, thiab corrosion kuj. Lawv raug qhuas tias yog "hlau ntawm lub neej yav tom ntej" thiab cog lus rau cov khoom siv tshiab. Titanium thiab nws cov alloys tsis yog tsuas yog muaj cov ntawv thov tseem ceeb hauv kev lag luam aviation thiab aerospace, tab sis kuj tau pib siv dav hauv ntau yam kev lag luam xws li tshuaj lom neeg, roj av, lub teeb kev lag luam, metallurgy, thiab kev tsim hluav taws xob. Titanium tiv taus corrosion los ntawm tib neeg lub cev thiab tsis muaj teeb meem, tso cai rau nws siv dav hauv kev kho mob thiab tshuaj lag luam. Titanium kuj muaj cov khoom siv roj zoo thiab tau siv dav hauv tshuab nqus tsev hluav taws xob thiab siab - tshuab nqus tsev.

1. Tsawg ceev, muaj zog tshwj xeeb

Qhov ceev ntawm titanium hlau yog 4.51 g / cm³, uas siab dua aluminium tab sis qis dua hlau, tooj liab, thiab npib tsib xee. Txawm li cas los xij, nws lub zog tshwj xeeb yog thawj zaug ntawm cov hlau.

2. Corrosion Resistance

Titanium yog cov hlau nquag heev uas muaj qhov sib npaug qis, txhais tau tias nws muaj qhov kub siab thermodynamic nyiam corrode hauv ntau yam xov xwm. Hauv kev muaj tiag, txawm li cas los xij, titanium ruaj khov hauv ntau yam xov xwm; Piv txwv li, nws yog corrosion-resistant nyob rau hauv oxidizing, nruab nrab, thiab tsis muaj zog tiv thaiv ib puag ncig. Qhov no yog vim titanium muaj zog affinity rau oxygen. In air or oxygen-containing media, a dense, strongly adherent, and highly inert oxide film forms on the titanium surface, protecting the titanium substrate from corrosion. Txawm hais tias puas los ntawm kev siv tshuab, cov yeeb yaj kiab no sai sai rau nws tus kheej - kho lossis rov tsim dua tshiab. Qhov no qhia tau hais tias titanium yog cov hlau uas muaj zog passivation nyiam. Titanium's oxide zaj duab xis tuav cov yam ntxwv ntawm cov xov xwm kub hauv qab 315 degree.

Txhawm rau txhim kho titanium qhov kev tiv thaiv corrosion, kev kho deg technologies xws li oxidation, electroplating, plasma spraying, ion nitriding, ion implantation, thiab laser kho tau raug tsim. Cov txheej txheem no txhim kho qhov kev tiv thaiv ntawm titanium's oxide zaj duab xis, ua tiav cov kev xav tau corrosion. Txhawm rau ua kom tau raws li qhov xav tau ntawm cov khoom siv hlau hauv ib puag ncig xws li sulfuric acid, hydrochloric acid, methylamine daws, siab -kub ntub dej chlorine gas, thiab siab -kub chlorides, muaj kev txhim kho corrosion- tiv taus titanium alloys, xws li titanium-molybdenum{6}titanium{6} thiab titanium. titanium-molybdenum-nickel alloys. Piv txwv li, titanium-32 molybdenum alloy yog siv rau titanium castings, titanium-0.3 molybdenum-0.8 npib tsib xee alloy yog siv nyob rau hauv ib puag ncig uas muaj crevice los yog pitting corrosion, thiab titanium-0.2 palladium alloy yog siv rau hauv zos seem ntawm titanium khoom, tag nrho cov zoo heev.

3. Kev ua haujlwm kub zoo

Cov hom tshiab ntawm titanium alloys tuaj yeem siv tau rau lub sijhawm ntev ntawm 600℃lossis siab dua.

4. Zoo Tsawg-Tsuas Ua Haujlwm Zoo

Tsawg- kub titanium alloys, sawv cev los ntawm TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V), thiab Ti-2.5Zr-1.5Mo, nthuav tawm lub zog ntau dua li qhov kub thiab txias, nrog kev hloov me ntsis hauv plasticity. Lawv tuav zoo ductility thiab toughness ntawm qis kub ntawm -196℃mus rau -253 degree, tsis txhob txias brittleness, ua rau lawv zoo tagnrho cov ntaub ntawv rau kub-kub ntim, cia tank, thiab lwm yam khoom siv.

5. Muaj zog Anti-Damping Capacity

Tom qab raug rau cov neeg kho tshuab lossis hluav taws xob kev co, titanium hlau muaj qhov ntev tshaj plaws ntawm tus kheej - vibration decay lub sij hawm piv rau cov hlau thiab tooj liab. Cov cuab yeej no tso cai rau titanium siv rau hauv cov diav rawg, ultrasonic crusher vibration ntsiab nyob rau hauv cov tshuaj, thiab kev co diaphragms rau siab - kawg suab hais lus.

6. Tsis yog -Magnetic and Non-Toxic

Titanium yog cov hlau tsis muaj - hlau nplaum thiab yuav tsis ua hlau nplaum txawm nyob hauv cov hlau nplaum muaj zog. Nws tsis yog - tshuaj lom thiab muaj kev sib raug zoo nrog tib neeg cov ntaub so ntswg thiab ntshav, ua rau nws mus rau hauv kev kho mob.

7. Tensile Strength ze rau yield zog

Cov cuab yeej ntawm titanium no qhia tau hais tias muaj txiaj ntsig zoo (lub zog tensile / lub zog tawm los), lub ntsiab lus titanium cov ntaub ntawv muaj cov yas tsis zoo thaum lub sij hawm tsim. Vim tias titanium muaj qhov sib piv siab ntawm cov txiaj ntsig txwv rau elastic modulus, nws nthuav tawm qhov tseem ceeb springback thaum tsim.

8. Kev ua haujlwm zoo thaum tshav kub kub

Txawm hais tias lub thermal conductivity ntawm titanium hlau yog qis dua li ntawm cov hlau thiab tooj liab, nws zoo heev corrosion kuj tso cai rau txo cov phab ntsa thickness. Tsis tas li ntawd, kev sib pauv cua sov ntawm titanium nto thiab chav tshwm sim los ntawm kev sib xyaw ua ke, txo cov thermal tsis kam. Lub fact tias titanium nto tsis scale kuj txo thermal kuj, ho txhim kho titanium lub tshav kub kev ua tau zoo.

9. Tsawg Elastic Modulus

Lub elastic modulus ntawm titanium ntawm chav tsev kub yog 106.4 GPa, uas yog 57% ntawm cov hlau.

10. Gas Absorption Properties

Titanium yog cov tshuaj lom neeg muaj zog heev uas tuaj yeem hnov ​​​​mob nrog ntau lub ntsiab lus thiab cov tebchaw ntawm qhov kub thiab txias. Titanium gas absorption feem ntau yog hais txog nws cov kev cuam tshuam nrog carbon, hydrogen, nitrogen, thiab oxygen ntawm qhov kub siab.
