GR5 Titanium nplhaib

Dab tsi yog cov khoom siv ntawm GR5 titanium rings?

Siab zog
 

Qhov ceev ntawm titanium alloys feem ntau yog nyob ib ncig ntawm 4.51g / cm³, uas tsuas yog 60% ntawm cov hlau. Qee qhov siab - lub zog titanium alloys tshaj lub zog ntawm ntau cov qauv hlau alloy. Yog li ntawd, lub zog tshwj xeeb (lub zog / qhov ntom) ntawm titanium alloys yog ntau dua li ntawm lwm cov khoom siv hlau, thiab cov khoom siv nrog lub zog siab, zoo rigidity thiab lub teeb yuag tuaj yeem tsim tau. Titanium alloys yog siv nyob rau hauv lub cav Cheebtsam, thav duab, tawv, fasteners thiab tsaws gears ntawm aircraft.

High thermal siv

Kev khiav hauj lwm kub ntawm ob hom titanium alloys yog ob peb puas degrees siab dua li ntawm aluminium alloys. Lawv tseem tuaj yeem tuav lub zog xav tau ntawm qhov kub nruab nrab thiab tuaj yeem ua haujlwm ntev ntawm qhov kub ntawm 450 txog 500 degree. Ob hom titanium alloys tseem muaj lub zog tshwj xeeb hauv thaj tsam ntawm 150℃txog 500 degree, thaum lub zog tshwj xeeb ntawm aluminium alloys poob qis ntawm 150 degree. Kev ua haujlwm kub ntawm titanium alloys tuaj yeem ncav cuag 500 degree, thaum cov txhuas alloys qis dua 200 degree.

Zoo corrosion kuj

Titanium alloys muaj kev tiv thaiv corrosion zoo dua li cov hlau tsis muaj steel thaum ua haujlwm hauv huab cua ntub thiab dej hiav txwv. Nws muaj zog tshwj xeeb rau pitting corrosion, acid corrosion thiab kev nyuaj siab corrosion. Nws muaj corrosion kuj zoo heev rau alkali, chlorides, organic tshuaj uas muaj chlorine, nitric acid, sulfuric acid, thiab lwm yam. Txawm li cas los xij, titanium tsis zoo corrosion kuj los txo oxygen thiab chromium ntsev media.

Kev ua haujlwm kub qis- zoo
Titanium alloys tseem tuaj yeem tswj hwm lawv cov khoom siv kho tshuab ntawm qhov qis thiab ultra- qhov kub thiab txias. Titanium alloys uas zoo heev uas tsis muaj - qhov kub thiab txias tsis tshua muaj interstitial ntsiab, xws li TA7, tseem muaj peev xwm tuav ib tug tej yam plasticity ntawm -253℃. Yog li ntawd, titanium alloy kuj yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob qis.

Siab chemical reactivity

Titanium muaj cov tshuaj lom neeg ua haujlwm siab thiab ua rau muaj tshuaj lom neeg muaj zog nrog O2, N2, H2, CO, CO2, dej vapor, ammonia thiab lwm yam gases hauv huab cua. Thaum cov ntsiab lus carbon ntau dua 0.2%, TiC nyuaj yuav tsim nyob rau hauv titanium alloys. Thaum qhov kub thiab txias, nws tseem yuav tsim ib qho nyuaj TiN txheej txheej thaum reacting nrog N. Thaum qhov kub thiab txias siab tshaj 600 degree, titanium absorbs oxygen los tsim ib txheej hardened heev. Kev nce hauv cov ntsiab lus hydrogen kuj tuaj yeem tsim cov txheej nkig. Qhov tob ntawm cov tawv thiab nkig txheej txheej tsim los ntawm absorbing gas tuaj yeem ncav cuag 0.1 txog 0.15 hli, thiab qib hardening yog 20% ​​mus rau 30%. Titanium kuj tseem muaj cov tshuaj lom neeg muaj txiaj ntsig zoo thiab nws yooj yim rau adhering rau kev sib txhuam ntawm qhov chaw.

Tsawg thermal conductivity elasticity
Lub thermal conductivity λ ntawm titanium yog 15.24W / (m·K), uas yog kwv yees li 1/4 ntawm cov nickel, 1/5 ntawm cov hlau, thiab 1/14 ntawm txhuas. Txawm li cas los xij, thermal conductivity ntawm ntau yam titanium alloys yog li 50% qis dua li ntawm titanium. Lub elastic modulus ntawm titanium alloy yog kwv yees li ib nrab ntawm cov hlau, yog li nws muaj tsis zoo rigidity thiab nws nquag deformation. Nws tsis haum rau kev ua cov pas nrig thiab nyias- cov phab ntsa. Thaum lub sij hawm txiav, lub rebound ntawm machined nto yog loj heev, li ntawm 2 mus rau 3 lub sij hawm ntawm stainless hlau, ua rau hnyav kev sib txhuam, adhesion thiab bonding hnav nyob rau hauv lub rear lub ntsej muag ntawm lub cuab tam.

Cov khoom tseem ceeb ntawm titanium rings yog titanium lossis titanium alloy, uas muaj cov yam ntxwv hauv qab no:
Muaj zog corrosion kuj: Nws tuaj yeem tiv taus ntau yam acids, alkalis thiab corrosive ib puag ncig.
Lub zog siab: Lub zog ntawm titanium alloys siab dua li ntawm ntau cov ntaub ntawv hlau, ua rau lawv haum rau cov xwm txheej uas yuav tsum tau muaj zog.
Lub teeb yuag: Titanium muaj qhov ntom ntom, uas tuaj yeem txo qhov hnyav ntawm cov qauv.
Ntau lawm thiab Standards
Cov titanium rings uas tsim los ntawm peb lub tuam txhab ua raws li cov qauv ntawm GB / T 16598 thiab ASME SB381, thiab muaj ntau yam kev kho mob xws li forged nto thiab dov nto. Peb muaj cov kab ntau lawm rau titanium thiab titanium alloys, nrog rau txhua xyoo melting thiab casting muaj peev xwm ntawm 2,000 tons (los ntawm 2025), thiab tau dhau ntau qhov kev pov thawj zoo thoob ntiaj teb. Peb cov khoom raug xa tawm mus rau ntau lub tebchaws tsim.
Daim ntawv thov teb

Peb lub tuam txhab tshwj xeeb hauv GR5 titanium rings. Tsawg-kev ntxhov siab GR5 tau tsim Cov txheej txheem tsim khoom ntawm titanium alloy nplhaib qhov chaw ua raws li cov kauj ruam no: Ua ntej, kub thiab tuav lub titanium alloy bar, ces chim siab thiab xuas nrig ntaus nws. Tom qab ua ntej- dov, nws yog thaum kawg dov rau hauv ib lub nplhaib. Lub nplhaib feem cuam tshuam kev kho mob. Thaum lub sij hawm ua kom txias, ib qho dej nruab nrab ntawm Ntau dua lossis sib npaug li 150℃yog siv. Tom qab kev daws teeb meem, kev nthuav dav txias yog nqa tawm, nrog kev nthuav dav ntawm 1.8% mus rau 2.2%. Tom qab kev nthuav dav, kev kho kev laus yog ua kom tau txais qhov qis-kev nyuaj siab titanium alloy nplhaib qhov chaw. Txoj kev no tuaj yeem tshem tawm qhov kev ntxhov siab ntawm titanium alloy rings thiab txhim kho kev ua haujlwm ntawm forgings.
