Nondestructive Testing NDT ntawm Titanium

Tsis yog-kev sim ua phem (NDT) ntawm cov khoom lag luam titanium yog qhov tseem ceeb los xyuas kom lawv cov qauv kev ntseeg, tshwj xeeb, tshwj xeeb yog nyob rau hauv kev lag luam tseem ceeb, kev cog lus kev kho mob, thiab kev ua haujlwm.

Titanium cov khoom tshwj xeeb (piv txwv li lub zog muaj zog-rau-hnyav piv, corrosion tsis kam) yuav tsum tau cov tswv yim ndt tshwj xeeb.

1. Ultrasonic kuaj (ut)
- Daim ntawv thov: Ntes Sab hauv Flasws (porosity, suav, suav nrog) hauv titanium alloys, xws li titanium pas nrig, forge, tuab phaj
- Cov txiaj ntsig: muaj kev nyuaj siab rau qhov tsis xws luag; tuaj yeem ntsuas cov tuab.
- Cov kev sib tw: Yuav tsum tau coupks thiab ke cov ua haujlwm; lis qauv yuav ua rau nrov nrov.
- Cov neeg sib txawv: phased array Ut (Paut) thiab lub sijhawm-ntawm-davhlau diffraction (tofd) txhim kho qhov raug.

2. Radnegraphic Xeem (RT)
- Daim ntawv thov: Txheeb xyuas cov xwm txheej sab hauv (voids, tawg, tsis muaj fusion hauv wends).
- Qhov zoo: muab cov ntaub ntawv nyeem tas mus li; Zoo rau cov geometries.
- Cov kev sib tw: Kev txhawj xeeb txog kev nyab xeeb kev nyab xeeb; Ua tsis tau zoo rau lub tswv yim tsis xws luag mus rau lub nqaj.

3. Eddy Txoj Kev Kuaj Tam Sim No (ect)
- Daim ntawv thov: nto thiab ze-nto qhov tseeb nrhiav kom pom, kev txheeb xyuas qhov tseeb.
- Cov txiaj ntsig: nrawm, tsis muaj coupant xav tau; Zoo rau cov nplooj ntawv titanium lossis txheej txheej.
- Qhov kev txwv: txwv tsis pub tob; nkag siab nqa tawm-off variations.

4. Kev sim tshuaj ntsuam (PT)
- Daim ntawv thov: Ntes nto tawg tsis xws luag (tawg, porosity), vuam sib dhos, vuam kab, vuam kab
- Qhov zoo: Yooj yim, tus nqi qis, portable.
- Qhov kev txwv: tsuas yog qhov tsis xws luag; yuav tsum muaj cov chaw huv.

Cov kev txiav txim siab tseem ceeb rau Titanium Khoom Muag NDT
- Cov Khoom Siv: Titanium's coarse nplej qauv yuav ua rau ultrasonic tawg.
- Cov Mob Nthaus: Oxide Txheej Txheem yuav cuam tshuam rau eddy tam sim no lossis kev sim tshuaj tiv thaiv.
- Ua raws li ASTM, ASME, lossis ISO cov qauv (piv txwv li, Ams 4928 rau aerospace, ttm f136 rau kev mob kho mob).

Cov Kev Siv Kev Lag Luam
- Aerospace: ut thiab rt rau titanium turbine hniav, airframe Cheebtsam.
- Roj & Roj: PT thiab siv rau corrosion-resistant titanium weld yeeb nkab thiab fittings.
