X-ray & Gamma-ray Radiographic Inspection Applications Ntawm Titanium Alloys

Titanium alloy precision load-cov kabmob thiab siab-cov kabmob cov kabmob yog qhov ua rau muaj qhov tsis xws luag sab hauv xws li qhov pores thiab tawg thaum lub sijhawm casting, forging thiab vuam txheej txheem. Cov kev tsis zoo no ua rau cov khoom siv ua haujlwm tsis zoo, ua rau lub neej ua haujlwm luv luv thiab tuaj yeem ua rau muaj kev nyab xeeb. Qhov tseeb thiab ua tau zoo uas tsis yog -kev kuaj kev puas tsuaj (NDT) yog qhov tseem ceeb los lav lawv qhov zoo thiab kev nyab xeeb ntawm kev ua haujlwm.

 

Kev ntsuam xyuas hluav taws xob sawv cev yog txoj hauv kev tseem ceeb rau kev kuaj pom cov teeb meem sab hauv, uas muaj cov duab pom tseeb thiab cov txiaj ntsig kev xeem tau. X-rays thiab gamma{2}}rays yog dav siv nyob rau hauv industrial radiographic tshuaj ntsuam. Txawm hais tias lawv qhia cov qauv zoo sib xws, lawv sib txawv hauv qib zog, qhov muaj peev xwm nkag mus, cov cuab yeej teeb tsa thiab cov xwm txheej siv tau.

 

 

Ob leeg X-rays thiab gamma-rays yog siab-frequency electromagnetic radiation muaj peev xwm nkag mus rau cov khoom siv. Radiographic inspection of titanium alloys relies on imaging based on differential ray attenuation: as rays pass through a workpiece, the dense substrate, pores and inclusions absorb and attenuate rays to varying degrees, resulting in differences in the intensity of transmitted radiation.

Qhov sib txawv ntawm cov kab hluav taws xob sib txawv tsim cov duab greyscale

 

ntawm cov duab hluav taws xob lossis cov khoom siv digital, ua rau cov neeg soj ntsuam xyuas cov hom, qhov loj thiab qhov chaw ntawm qhov tsis xws luag. Txoj kev no muab kev tshawb nrhiav zoo heev rau qhov tsis xws luag xws li qhov pores, thiab siv rau titanium alloy castings, weldments thiab forgings. Nws tseem raug xaiv los ua tus txheej txheem sim thawj zaug raws li ISO 17636-2022 tus qauv.

 

 

1.Core Technical yam ntxwv

X-rays feature adjustable zog, siab imaging clarity thiab yooj yim controllable hluav taws xob, nrog rau kev ua hauj lwm yooj yim thiab ceev imaging ceev. Lawv muab lub zog nkag mus rau nruab nrab nrog qhov kev daws teeb meem siab tshaj plaws ntawm 4-5 kab khub hauv ib millimeter, ua kom pom qhov qis - sib piv microdefects xws li me me pores thiab suav nrog hauv titanium alloys.

Tsis muaj hluav taws xob seem raug tsim tawm; cov cuab yeej tuaj yeem qhib thiab kaw tau yooj yim nrog kev nyab xeeb kev nyab xeeb, ua rau nws tsim nyog rau kev soj ntsuam batch rhiav. Nws qhov kev txwv tseem ceeb yog nyob rau hauv qhov muaj peev xwm nkag mus tsis txaus, ua rau nws tsis tsim nyog rau tuab titanium alloy workpieces.

 

2.Daim ntawv thov Scenario

1.Thin-walled titanium alloy Cheebtsam: Tau tshaj 2-50 mm daim hlau, nyias-walled castings thiab tiav-machined qhov chaw, dav siv rau aircraft tawv thiab turbine hniav los xyuas txog microporosity thiab shrinkage.

 

2.Kev soj ntsuam ntawm titanium alloy welds: Kom meej meej qhia weld defects xws li pores, microcracks, tungsten inclusions thiab incomplete penetration, thov rau kev lees paub ntawm aerospace pipelines thiab kev kho mob -qib titanium alloy welded sib dhos.

 

3.Batch soj ntsuam ntawm precision me me qhov chaw: ceev thiab ruaj khov imaging txhawb siab -efficiency batch ntsuam xyuas rau nruj Hoobkas zoo tswj.

3.Qhov zoo thiab qhov tsis zoo

• Qhov zoo: Kev daws teeb meem siab, muaj peev xwm zoo tshaj plaws los kuaj xyuas microdefects, kho qhov tsis zoo, kev nyab xeeb thiab ua haujlwm tau zoo, ruaj khov duab zoo.
• Qhov tsis zoo: tsis muaj zog nkag mus, tsuas yog siv tau rau nruab nrab thiab nyias- cov khoom siv phab ntsa; siab kev yuav khoom thiab tu nqi rau cov khoom siv.

 

1.Core Technical yam ntxwv

Gamma-rays xa tawm lub zog tas li thiab muaj zog nkag mus deb dua li X-rays, ua rau kev tshuaj xyuas ntawm titanium alloy workpieces tuab dua 50 mm. Gamma- cov khoom siv hluav taws xob yog lub teeb yuag thiab lub zog- pub dawb, txhawb kev ua haujlwm hauv thaj chaw nyuaj xws li qhib qhov chaw thiab siab - qhov chaw siab.

Txawm li cas los xij, gamma-ray hluav taws xob tsis tuaj yeem tswj hwm, ua rau cov duab tsis zoo thiab tsis muaj zog microdefect kom pom qhov ua tau zoo piv nrog X-rays. Cov khoom siv hluav taws xob tsis tu ncua tso tawm hluav taws xob, ua kom muaj kev tiv thaiv hluav taws xob nruj.

 

2.Daim ntawv thov Scenario

Kev tshuaj xyuas hnyav -section titanium alloy Cheebtsam: Siv rau forgings, ingots thiab nuclear siab- bearing qhov siab tshaj 50 mm nyob rau hauv thickness kom paub qhov tob -seed shrinkage kab noj hniav, inclusions thiab tawg.

 

Ntawm -qhov chaw kuaj pom qhov tsis txaus: tshem tawm qhov xav tau los thauj cov khoom loj thiab cov khoom siv vuam, tso cai rau ntawm - qhov chaw tshuaj xyuas ncaj qha.

Kev soj ntsuam ntxhib ntawm tuab- cov khoom siv phab ntsa hauv cov khoom siv: Loj ib zaug - tshuaj ntsuam xyuas qhov zoo tshaj plaws rau kev soj ntsuam zoo ntawm cov khoom loj.

3.Qhov zoo thiab qhov tsis zoo

Qhov zoo: Muaj peev xwm nkag mus tau zoo, lub zog txav tau yooj yim- cov khoom siv dawb, hloov tau mus rau qhov chaw nyuaj, cov nqi kuaj xyuas tsawg.

Disadvantages: Tsawg imaging precision, nyuaj txheeb xyuas microdefects, uncontrollable persistent hluav taws xob, nruj kev tiv thaiv kev ruaj ntseg thiab kev tswj cov kev cai.

 

 

X-ray thiab gamma{1}}ray radiographic kuaj txhua tus muaj qhov xwm txheej tshwj xeeb. Kev xaiv yuav tsum tau txiav txim siab raws li titanium alloy workpiece thickness, qauv, precision yuav tsum thiab ib puag ncig kev khiav hauj lwm:

 

1.Xaiv X-ray kuaj rau siab- kev tshuaj ntsuam xyuas qhov tseeb, nyias- cov phab ntsa me me, qhov tseeb welds, aerospace thiab cov khoom siv kho mob. Nws kuaj pom microdefects ntseeg tau thiab haum rau kev kuaj xyuas batch ruaj khov.

 

2.Xaiv gamma-ray kuaj rau hnyav-section forgings ntau dua 50 mm tuab, cov qauv loj thiab teb ntawm- qhov chaw kuaj pom qhov tsis zoo, siv nws qhov kev nkag mus tau zoo thiab cov khoom siv nqa tau yooj yim.

3.Rau qhov tseem ceeb ntawm kev thauj khoom-cov khoom siv bearing, kev sib xyaw ua ke ob- txheej txheem tshuaj xyuas tuaj yeem raug txais: ua ntej ua qhov dav - ntau yam kev tshuaj ntsuam xyuas nrog gamma-rays, ua raws li kev soj ntsuam xyuas zoo nrog X-rays kom sib npaug tag nrho cov kev pab cuam thiab nrhiav kom raug.
