Kev ua tau zoo zoo thiab noo noo-pov thawj kev ua tau zoo ntawm Titanium Alloy Screws

Piv nrog cov pa fasteners xws li stainless hlau thiabcarbon steel screws, titanium alloy screws qhia tau zoo heev cov khoom siv kho tshuab thiab ib puag ncig adaptability. Lawv yog cov nyiam fasteners rau high-end khoom, aerospace, marine ua hauj lwm tej yam kev mob thiab precision instruments. Kab lus no piav qhia txog cov txiaj ntsig ntawm kev ua tau zoo, cov txheej txheem kho cua sov thiab kev tiv thaiv kev tiv thaiv ntawm titanium alloy screws.

1. Core Performance Advantages ntawmTitanium Alloy Screws

1. Ultra-high Specific Strength

Titanium alloy nta lub zog tshwj xeeb heev (qhov sib piv ntawm lub zog tensile rau qhov ntom). Nws lub zog tensile ncav cuag 100 ~ 140kgf / mm², thaum nws qhov ceev tsuas yog 60% ntawm cov hlau. Nyob rau hauv tib lub zog yuav tsum tau, titanium alloy screws yog sib dua nyob rau hauv qhov hnyav, uas zoo paub txog lub teeb yuag ntawm cov khoom siv.

2. Zoo heev nruab nrab-kub muaj zog

Titanium alloy muaj qhov kub thiab txias zoo dua li aluminium alloy. Nws tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev ntawm 450℃~ 500℃thiab tswj lub zog zoo ib yam, ua rau nws tsim nyog rau cov khoom siv fastening nyob rau hauv ntau yam nruab nrab thiab kub kub ua haujlwm.

3. Superior Corrosion Resistance

When exposed to the atmosphere, a dense and uniform inert oxide protective film will instantly form on the surface of titanium alloy, effectively isolating corrosive media. Nws ua tau zoo heev nyob rau hauv nruab nrab thiab oxidizing ib puag ncig xws li atmospheric tej yam kev mob, seawater, humid chlorine gas thiab chloride daws. Txawm li cas los xij, nws cov kev tiv thaiv corrosion kuj txo qis hauv kev txo cov kua qaub tawm xws li hydrochloric acid.

4. Zoo tshaj qhov kub-kub toughness

Tsawg-interstitial titanium alloys (xws li TA7) muaj qhov ua tau zoo ntawm qhov kub thiab txias. Lawv tuaj yeem tuav cov yas zoo ntawm qhov kub qis ntawm -253℃yam tsis muaj qhov txias txias thiab tawg, thiab muaj feem xyuam rau cov khoom siv cryogenic thiab cov haujlwm ua haujlwm kub kub.

5. Lub cev muaj zog zoo heev

Titanium alloy screwsmuaj cov qauv qis elastic, tsis tshua muaj thermal conductivity thiab cov khoom tsis sib nqus uas tsis muaj kev cuam tshuam sib nqus, uas tsim nyog rau cov ntawv thov tshwj xeeb xws li cov cuab yeej precision, cov khoom siv hluav taws xob thiab cov khoom siv kho mob.

6. Siab hardness thiab muaj zog tus qauv ruaj khov

Titanium alloy muaj siab zuag qhia tag nrho hardness thiab muaj zog extrusion thiab hnav tsis kam. Nws tsis yooj yim rau deform thaum lub sij hawm kev pab cuam mus sij hawm ntev thiab tuav zoo heev locking stability raws li ib tug fastener.

7. Kev ua haujlwm thermal zoo

Titanium alloy muaj qhov nruab nrab stamping kev ua tau zoo ntawm chav tsev kub tab sis zoo heev thermoplasticity ntawm qhov kub thiab txias. Ntau yam tshwj xeeb-zoo li tus ntsia hlau tuaj yeem ua tiav los ntawm kev kub forging thiab kub sib sau nrog ruaj khov molding zoo.

2. Kev kho cua sov txheej txheem ntawmTitanium Alloy Screws

Kho cov txheej txheem kev kho cua sov tuaj yeem hloov cov txheej txheem sab hauv ntawm titanium alloy kom ua tau raws li cov kev xav tau sib txawv rau lub zog, toughness thiab qaug zog ua haujlwm. Cov qauv zoo equiaxed xa cov yas zoo, thermal stability thiab qaug zog; cov qauv acicular muab lub zog muaj zog ntau dua, nkag siab lub zog thiab tawg toughness; sib xyaw equiaxed thiab acicular lug ua tiav qhov zoo tshaj plaws kev ua haujlwm zoo tshaj plaws.

Cov txheej txheem kev kho cua sov feem ntau rau cov titanium alloys suav nrog annealing, kev daws teeb meem thiab kev kho kev laus. Annealing feem ntau yog siv los tshem tawm cov kev ntxhov siab sab hauv, txhim kho plasticity thiab cov qauv kev ruaj ntseg, thiab txhim kho kev ua tau zoo. Rau cov pa alloys thiab ( + ) alloys, qhov kub ntawm annealing yog teem rau 120℃~ 200℃hauv qab no theem hloov point ntawm ( + ) → .

Kev daws thiab kev laus kev kho mob yog cov txheej txheem ntxiv dag zog. Kev txias nrawm ntawm qhov kub thiab txias tau txais cov qauv metastable, thiab tom qab ntawd nruab nrab-kub kub preservation txhawb cov nag lossis daus ntawm dispersed thib ob-theem hais los ntawm cov theem metastable kom ntxiv dag zog rau cov hlau. Lub quenching kub ntawm (+) alloys yog 40℃~ 100℃hauv qab ntawm theem hloov chaw, thaum lub metastable alloys yog 40℃~ 80℃saum toj no theem hloov point. Cov pa kub kub yog tswj ntawm 450℃~ 550 degree.

Txhawm rau ua kom tau raws li cov kev cai tshwj xeeb ntawm kev ua haujlwm, kev tsim kho kev lag luam xws li muab ob npaug rau annealing, isothermal annealing, kev kho cua sov thiab kev kho thermomechanical tuaj yeem siv los ua kom zoo dua qhov kev ua tau zoo ntawm titanium alloy screws.

3. Moisture-pov thawj Performance thiab tiv thaiv kev ntsuas ntawmTitanium Alloy Screws

Titanium alloy nws tus kheej muaj peev xwm ua tau zoo noo noo-pov thawj, ntub-pov thawj thiab xeb-pov thawj, thiab yuav tsis xeb los yog oxidize thiab poob rau hauv huab cua ntub thiab cov av noo ib puag ncig. Txawm li cas los xij, kev kho kev tiv thaiv saum npoo tseem yuav tsum tau siv rau kev pabcuam mus ntev hauv qhov kub thiab txias siab, tshuaj tsuag ntsev, kua qaub thiab alkali corrosive ib puag ncig kom ntev kev pab cuam lub neej thiab stabilize cov tsos thiab kev ua haujlwm. Cov txheej txheem tiv thaiv feem ntau yog raws li hauv qab no:

1. Kev xaiv cov xim tiv thaiv insulating: Ua ntej epoxy resin thiab polyurethane impregnating xim tsis muaj volatile acid. Cov xim tsis muaj kuab tshuaj yog pom zoo rau cov khoom siv vibrating kom tsis txhob muaj xim corrosion thiab tev.

2. Kev tswj cov txheej txheem curing: Thaum siv melamine alkyd xim rau kev tiv thaiv, nruj me ntsis tswj qhov curing tsis. Qhov kub curing yuav tsum yog me ntsis siab dua 130℃nrog lub sijhawm kho tsis pub tsawg tshaj 180 feeb. Tshwj xeeb tshaj yog nyob rau lub caij kub thiab av noo, cov txheej txheem kho kom tiav yuav tsum tau ua los tiv thaiv cov xim tev thiab noo noo rov tshwm sim los ntawm kev kho tsis tiav.

3. Kev kho deg los tiv thaiv corrosion: Ntau yam txheej txheem sealing yog saws los tsim cov txheej txheem tiv thaiv ntawm qhov chaw.titanium alloy screws, cais tawm sab nraud ya raws thiab corrosive media, inhibiting corrosion tshwm sim thiab ntxiv txhim kho kev tiv thaiv kev ua haujlwm hauv high-humidity ua haujlwm.

4. Cov Ntsiab Cai Xaiv Cov Ntsiab Cai ntawm Titanium Alloy Screws

1. Mechanical performance matching: Xaiv cov khoom siv titanium alloy nrog cov qib sib luag raws li cov khoom siv ceev ceev kom ua tau raws li tensile, shear thiab compressive mechanical indicators.
