Cov khoom siv titaniumtau nce dav siv hauv kev lag luam xws li tshuaj lom neeg kev lag luam thiab aerospace. Txawm li cas los xij, nrog ntau cov ntaub ntawv sib txawv, cov lus qhia tshwj xeeb, thiab cov txheej txheem tsim khoom xaiv los ntawm, yuav ua li cas thiaj xaiv tau zoo thaum yuav khoom titanium?
I. Cov ntawv thov kev lag luam thiab cov kev xav tau tseem ceeb ntawm cov khoom siv titanium
Los ntawm cov tshuaj reactors mus rau aerospace fasteners, tus nqi tseem ceeb ntawm cov khoom titanium nyob hauv lawv cov khoom siv tshwj xeeb:
Corrosion Resistance: Withstands muaj zog acids, muaj zog alkalis, thiab seawater ib puag ncig
Lub zog-rau- Qhov hnyav piv: Qhov tseem ceeb rau qhov hnyav txo hauv kev lag luam aerospace
Biocompatibility: Cov khoom ntawm kev xaiv rau kev kho mob cog
Kev lag luam ntau tshaj plaws -tawm tau ntsib hauv kev yuav khoom tiag tiag yog:
Ntshiab titanium (piv txwv li, ntshiab titanium rods) yog tus nqi - zoo tab sis tsis muaj zog txaus
Titanium alloys (xws li, titanium alloy daim hlau) muaj kev ua tau zoo dua tab sis nyuaj rau tshuab
II. Khoom Properties thiab Classification ntawm Titanium khoom
Qhov sib txawv ntawm kev ua tau zoo ntawm cov khoom titanium feem ntau yog los ntawm cov khoom muaj pes tsawg leeg thiab cov txheej txheem tsim khoom:
Ntshiab Titanium Series (Gr1-Gr3)
Zoo corrosion kuj tab sis nruab nrab mechanical zog
Haum rau kev siv zoo li qub xws li cov txheej txheem tshuaj lom neeg cov hlab ntsha
Titanium Alloy Series (Gr5, thiab lwm yam)
Lub zog txhim kho los ntawm kev sib ntxiv ntawm cov khoom xws li txhuas thiab vanadium
Qhov kev xaiv zoo tshaj plaws rau aerospace structural Cheebtsam
Cov khoom tshwj xeeb titanium (piv txwv li, titanium diboride khoom)
Cov ntawv thov tshwj xeeb hauv qhov chaw huab cua
Tus nqi siab dua tab sis kev ua tau zoo dua
Kev xav tsis zoo: Kev ntseeg tias "txhua yam khoom siv titanium zoo ib yam," saib qhov sib txawv ntawm qib, thiab xaiv cov khoom siv tsis zoo kom txuag tau tus nqi.
Xaus: Cov khoom qib ncaj qha txiav txim siab lub neej kev pabcuam; tus nqi ib leeg yuav tsum tsis yog qhov kev txiav txim siab
III. Yuav ua li cas xaiv cov khoom Titanium raws li daim ntawv thov scenarios
|
Scenario Requirements |
Pom zoo tshuaj |
Ntsiab Parameters |
| Corrosive Ib puag ncig | Ntshiab Titanium Sheets / Tubes | Gr1/Gr2 Qib, Alkali-Ntaus nto |
| Cov qauv thauj khoom-cov kabmob | Gr5 titanium alloy | 6% aluminium + 4% vanadium, kub- dov |
| Siab -kub, siab - cov kav dej siab | Titanium cov kav dej | Thick -cov kav dej seamless, UT soj ntsuam raws |
| Tswj kua | Titanium li qub | Flange Connection, Tus kheej -Actuated |
IV. Dab tsi ntxiv xav tau tom qab yuav cov khoom titanium?
1. Welding Challenges: Cov khoom siv vuam zoo tuaj yeem ua rau embrittlement ntawm kev sib koom tes.
Tshwj xeeb titanium vuam hlau ua kom muaj zog vuam.
Inert gas shielding yog yuav tsum tau.
Machining Limitations: Titanium cov khoom yuav tsum tau tshwj xeeb txiav tsis.
2. Titanium machining cov cuab yeej yuav tsum tau hloov ntawm spindle ceev thiab pub tus nqi.
Tsis txhob siv cov pa roj carbon- muaj cov cuab yeej txiav.
3. Kev kho deg:
Micro-arc oxidation txhim kho hnav tsis kam.
Nitriding txhim kho qhov tawv tawv.
