Txoj Kev Tshuaj Xyuas Rau Nickel-raws li Alloys

Cov txheej txheem tshuaj xyuas rau nickel-raws li alloys (xws li Inconel, Hastelloy, thiab lwm yam) yuav tsum tau ua kom zoo raws li lawv cov khoom tshwj xeeb (xws li kub tsis kam, corrosion kuj, tsis yog -magnetic, thiab lwm yam). Cov hauv qab no yog cov uas nquag siv tsis yog -kev kuaj kev puas tsuaj (NDT) txoj hauv kev rau nickel-raws li alloys thiab lawv cov ntsiab lus kev:

 

1. Kev Ntsuas Ultrasonic (UT)

Cov xwm txheej uas siv tau: Kev txheeb xyuas cov teeb meem sab hauv (xws li cov kab nrib pleb, qhov pores, suav nrog, thiab lwm yam);

Muaj feem xyuam rau cov tuab- phab ntsa, rods, forgings, thiab lwm yam.

Cov ntsiab lus tseem ceeb: Kev sojntsuam xaiv: Longitudinal yoj ncaj sojntsuam (rau kev kuaj pom qhov tsis zoo)

Transverse yoj oblique sojntsuam (rau kev kuaj pom cov kab nrib pleb, pom zoo 45℃- 70 degree)

Coupling tus neeg saib xyuas: Siab -kub glycerol lossis tshwj xeeb coupling tus neeg sawv cev (tsim rau cov yam ntxwv siab ntom ntom ntawm nickel{1}}raws li alloys)

Calibration block: Ib qho thaiv uas txuam nrog cov khoom acoustic ntawm nickel{0}}raws li alloys (xws li ASTM E317) yuav tsum tau

Phase array ultrasonic (PAUT): tuaj yeem txhim kho kev tshawb pom kev ua haujlwm thiab raug, muaj feem xyuam rau cov khoom ua haujlwm nrog cov duab nyuaj

Qhov zoo: tuaj yeem kuaj pom qhov tsis xws luag

Tsis cuam tshuam los ntawm cov khoom siv hlau nplaum

 

2. Kev Xeem Penetrant (PT)

Cov xwm txheej uas siv tau: Kev kuaj pom ntawm qhov chaw- qhib qhov tsis xws luag (xws li tawg, pinholes, thiab lwm yam)

Siv tau rau saum npoo ntawm tag nrho cov nickel{0}}raws li alloys

Cov ntsiab lus tseem ceeb: Penetrant hom: Fluorescent penetrant (siab rhiab heev)

Sensitized penetrant (tsim rau ntawm -qhov chaw kuaj pom)

Tus neeg saib xyuas tu: Yuav tsum muaj cov tshuaj chlorine tsawg (kom tiv thaiv tau cov tshuaj chlorine-induced stress corrosion)

Tus neeg saib xyuas duab: Cov hmoov qhuav los yog ntub - hom duab tus neeg saib xyuas

Qhov zoo: Kev ua haujlwm yooj yim, tus nqi qis

Nws tuaj yeem ntes cov workpieces nrog cov duab nyuaj

 

3. Eddy Current Testing (ET)

Cov xwm txheej uas siv tau: Kev kuaj pom ntawm qhov chaw thiab nyob ze - qhov chaw tsis xws luag (xws li tawg, quav, qhov pores, thiab lwm yam)

Muaj feem xyuam rau nyias- cov hlab ntsa, cov hlua hlau, daim hlau

Cov ntsiab lus tseem ceeb: Kev xaiv zaus: nyias phab ntsa (<1mm): 100 - 500 kHz

Nruab nrab phab ntsa thickness (1 - 3mm): 50 - 100 kHz

Thick wall (>3mm): 10 - 50 kHz

Kev sojntsuam sib txawv: Txhim kho qhov kev tshawb pom ntawm qhov tsis xws luag (tuaj yeem ntes cov kab nrib pleb tob li 0.1 hli)

Calibration standard: Yuav tsum tau siv cov nickel{0}}raws li cov qauv tsis xws luag

Qhov zoo: Kev tshawb nrhiav ceev ceev, haum rau kev tshawb nrhiav hauv online

Tsis xav tau tus neeg sawv cev coupling, tsis yog - kev kuaj xyuas
