Nyob rau hauv lub neej, ib tug me me ntsia hlau yog feem ntau, thiab ib co yog cov me nyuam cov khoom ua si, tab sis nws yog ib tug me me ntsia hlau uas plays lub luag hauj lwm loj nyob rau hauv tag nrho cov mus rau lub neej. Nws yug los ua ib tug zoo leap nyob rau hauv tib neeg kev lag luam kev loj hlob, thiab cov neeg nyob rau hauv lub industrial teb yuav ntsia hlau thiab nws zoo ib yam li hu ua "fasteners". Fasteners hu ua "industrial meters", Academician Wu Guanghui, tus thawj tsim ntawm C919 loj neeg nrog caij dav hlau, qhuas fasteners "ntau txhiab, chav kawm ntawv rau pab pawg neeg cov ntsiab lus, kev cob cog rua cov qauv, kev cob cog rua system, tej yam me me yog loj." Vim yog cov ntawv thov sib txawv, tib neeg siv cov khoom siv hlau sib txawv los tsim cov fasteners. Niaj hnub no, tus sau yuav coj koj mus rau systematically nkag siab txog titanium alloy fasteners thiab lawv daim ntawv thov dav.
Qhov zoo ntawm titanium alloy fasteners:
Me me, siab zog, siab tshwj xeeb zog
piv nrog cov ntaub ntawv hlau thiab hlau, titanium alloy muaj qhov ntom ntom me me thiab lub teeb yuag. Kev siv loj 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, 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.
Muaj zog corrosion kuj:
Titanium tsis corroded nyob rau hauv ib co corrosive media, xws li seawater, ntub chlorine gas, chlorite thiab hypochlorite tov, nitric acid, chromic acid, hlau chloride, sulfide thiab organic acid.
Titanium alloy fasteners yog dav siv nyob rau hauv Marine engineering, tshuaj refining thiab lwm yam teb.
Zoo kub tsis kam:
feem ntau yog txhuas ntawm 150 degree C, stainless hlau ntawm 310 degree C uas poob cov khoom qub, thiab titanium alloy ntawm txog 500 degree C tseem tuav cov khoom zoo. Thaum lub dav hlau ceev nce mus txog 2.7 npaug ntawm lub suab nrawm, qhov kub ntawm lub dav hlau qauv nce mus txog 230 degree C, aluminium alloy thiab magnesium alloy tsis tuaj yeem siv, thiab titanium alloy tuaj yeem ua tau raws li qhov yuav tsum tau ua.
Tsis-magnetic:
Titanium yog cov hlau tsis muaj hlau nplaum, yog li fasteners ua los ntawm titanium alloy yog qhov tsim nyog rau kev siv ntau yam ntawm cov tshuab precision kom tsis txhob muaj qhov sib nqus ntxiv ntawm cov tshuab no. Hauv kev lag luam aerospace, cov khoom tsis sib nqus ntawm titanium alloy fasteners tseem ceeb heev.
Lub coefficient ntawm thermal expansion thiab elastic modulus yog me me:
Lub coefficient ntawm thermal expansion thiab elastic modulus ntawm titanium alloy cov khoom yog me dua li cov nickel alloy thiab steel khoom, thiab thermal stress generated los ntawm titanium alloy yog me me nyob rau hauv tib lub kub hloov lub caij, yog li titanium alloy muaj siab thermal qaug zog kev kawm.
High tsos theem:titanium hlau nto tuaj yeem pom ntau yam xim, yog li nws tseem hu ua "xim titanium". Qhov kev txawj "xim" no yog qhov tshwj xeeb ntawm titanium hlau, titanium alloy fasteners tsis muaj qhov tshwj xeeb, ntau tus neeg nyiam siv cov yeeb yuj titanium alloy fasteners los qhia cov yam ntxwv tshwj xeeb.
Titanium alloy fasteners muaj kev ua tau zoo heev, haum rau daim ntawv thov hauv ntau qhov kev lag luam:
Aerospace:
Daim ntawv thov ntawm titanium alloy fasteners originated nyob rau hauv aerospace teb. Rov qab mus rau xyoo 1950, Tebchaws Meskas tau ua tus thawj coj hauv kev siv titanium alloy zawm bolts rau B-52 cov foob pob tawg, thiab ua tiav qhov hnyav hnyav.
Keeb kwm ntawm titanium alloy fasteners nyob rau hauv Tuam Tshoj pib nyob rau hauv 1965, thiab nyob rau hauv lub 1980s, ib tug me me ntawm titanium alloy fasteners xws li rivets thiab bolts pib siv rau ib co thib ob tiam tub rog aircraft nyob rau hauv Tuam Tshoj.
Nyob rau hauv xyoo tas los no, txoj kev loj hlob ntawm titanium alloy cov ntaub ntawv thiab kev tshawb fawb thiab kev loj hlob ntawm fastener manufacturing technology nyob rau hauv Tuam Tshoj tau txuas ntxiv mus, thiab titanium alloy fasteners yog dav siv nyob rau hauv lub aerospace teb thiab kuj tseem ceeb heev nyob rau hauv daim ntawv thov ntawm civil aircraft.
Marine engineering:
Nyob rau hauv Marine ib puag ncig, titanium alloy fasteners tuaj yeem tiv thaiv kev yaig ntawm cov dej hiav txwv, txhim kho kev pab cuam lub neej ntawm cov tshuab thiab pab tswj xyuas. Cov tsis sib nqus titanium alloy fasteners yog heev haum rau cov khoom ntawm lub submarine thiab yuav tsis ua rau tawg ntawm mines.
Kev lag luam tshuaj:
Kev lag luam tshuaj ib txwm yog qhov chaw loj tshaj plaws ntawm titanium hauv Suav teb, thiab lub luag haujlwm ntawm titanium alloy fasteners hauv kev lag luam no tsis tuaj yeem tsis quav ntsej.
Civil field:
Titanium alloy fasteners kuj tau siv dav hauv kev caij tsheb kauj vab, kev kho mob thiab lwm yam, nqa kev yooj yim thiab kev noj qab haus huv rau tib neeg lub neej thiab kev noj qab haus huv.
Nyob rau hauv luv luv, titanium alloy fasteners ua lub luag haujlwm tseem ceeb hauv aerospace, Marine engineering, chemical kev lag luam thiab pej xeem kev lag luam nrog lawv cov kev ua tau zoo. Txawm hais tias tus nqi ntawm titanium alloy yog tus nqi siab, nrog rau kev nce qib ntawm cov khoom siv titanium ntau lawm, daim ntawv thov ntawm titanium alloy fasteners nyob rau hauv pej xeem teb yuav zoo dua txhawb.
