Nyob rau hauv lub neej, ib tug me me ntsia hlau yog ib qho chaw, tab sis nws yog lub me me ntsia hlau uas plays lub luag hauj lwm loj nyob rau hauv tag nrho cov mus rau lub neej ntawm tib neeg lub neej, thiab nws yug los ua ib tug zoo leap nyob rau hauv kev loj hlob ntawm tib neeg kev lag luam. Hauv kev lag luam, tib neeg xa mus rau cov ntsia hlau thiab lawv cov hom zoo sib xws li "fasteners", thiab hu ua "industrial mov". Fasteners feem ntau yog tsim los ntawm cov khoom siv hlau sib txawv, thiab titanium alloy fasteners muaj lub luag haujlwm tsis tuaj yeem hloov pauv hauv ntau qhov chaw.
1. Lub zog tshwj xeeb: Piv nrog cov ntaub ntawv steel, qhov ntom ntawm titanium alloy yog 57% ntawm cov hlau. Kev siv ntau ntawm titanium alloy fasteners tuaj yeem txo cov neeg kho tshuab zoo thiab txo kev siv hluav taws xob, uas tsis yog ib qho teeb meem ntawm ib puag ncig nkaus xwb, tab sis kuj yog ib qho nyiaj txiag pom tseeb. Lub zog thiab lub zog tshwj xeeb ntawm titanium alloy yog zoo dua li ntawm aluminium alloy, thiab nws yog qhov pom tseeb zoo dua rau qee qhov chaw huab cua, xws li chaw thiab dej hiav txwv.
2. Muaj zog corrosion kuj: titanium alloy tsis corroded nyob rau hauv ib co corrosive media, xws li seawater, ntub chlorine, chlorite thiab hypochlorite tov, nitric acid, chromic acid, hlau chloride, sulfide thiab organic acid. Qhov no ua rau titanium alloy fasteners dav siv nyob rau hauv marine engineering, tshuaj refining thiab lwm yam teb.
3. Kev ua kom sov zoo: feem ntau yog txhuas ntawm 150 degree, stainless hlau ntawm 310℃uas poob nws cov khoom qub, thaum titanium alloy tseem tuav cov khoom zoo ntawm 500 degree. Piv txwv li, thaum qhov ceev ntawm lub dav hlau mus txog 2.7 npaug ntawm lub suab ceev, qhov kub ntawm lub dav hlau qauv nce mus txog 230 degree, aluminium alloy thiab magnesium alloy tsis tuaj yeem siv, thiab titanium alloy tuaj yeem ua tau raws li qhov yuav tsum tau ua.
4. Tsis yog-sib nqus: titanium yog cov hlau tsis muaj- hlau nplaum, yog li cov fasteners ua los ntawm titanium alloy yog tsim nyog rau siv nyob rau hauv ntau yam precision machinery kom tsis txhob muaj cov hlau nplaum ntxiv rau cov tshuab no. Hauv kev lag luam aerospace, qhov tsis yog - cov khoom sib nqus ntawm titanium alloy fasteners yog qhov tseem ceeb heev.
5. Me me coefficient ntawm thermal expansion thiab modulus ntawm elasticity: Lub coefficient ntawm thermal expansion thiab modulus elasticity ntawm titanium alloy cov ntaub ntawv yog me dua cov nickel alloy thiab steel cov ntaub ntawv, thiab thermal stress generated los ntawm titanium alloy yog heev me me nyob rau hauv tib lub kub hloov ntau yam, yog li titanium alloy muaj siab thermal qaug zog kev ua tau zoo.
6. Cov tsos mob siab: titanium hlau tuaj yeem pom ntau yam xim los ntawm kev kho saum npoo, yog li nws tseem hu ua "xim titanium". Cov txuj ci "xim" no yog cov cuab yeej tshwj xeeb ntawm titanium, thiab titanium fasteners tsis muaj qhov tshwj xeeb, thiab ntau tus neeg nyiam siv cov yeeb yuj titanium fasteners los qhia lawv cov yam ntxwv tshwj xeeb.
