Puas yuav titanium teeb tsa cov hlau ntes?
Nyob rau hauv lub neej niaj hnub no, hlau ntes tau nyob txhua qhov chaw, los ntawm subway kev ruaj ntseg mus rau archaeological excavation mus rau lub tsev khaws puav pheej pov thawj tiv thaiv, lawv ua lub luag hauj lwm tseem ceeb. Yog li thaum nws los txog rau cov hlau ntes, peb pab tsis tau tab sis nug xav paub ntxiv: Puas yog titanium, lub teeb yuag, corrosion-resistant "hlau yav tom ntej", ua rau lub tswb ntawm lub ntsuas hlau? Niaj hnub no, cia peb tshawb nrhiav kev sib raug zoo ntawm titanium thiab hlau ntes.
1. Cov yam ntxwv ntawm titanium hlau
Titanium yog ib qho xim dawb-dawb hloov pauv hlau nrog ntau lub cev thiab tshuaj lom neeg tshwj xeeb. Nws muaj qhov ntom ntom ntom ntom, siab zog, thiab zoo heev corrosion kuj. Nws yog lub npe hu ua "chaw hlau" thiab "ocean hlau". Cov yam ntxwv no ua rau titanium dav siv hauv aerospace, navigation, kho mob, khoom siv ua kis las thiab lwm yam haujlwm.
2. Lub hauv paus ntsiab lus ua haujlwm ntawm cov khoom siv hlau
Hlau detectors feem ntau yog siv lub hauv paus ntsiab lus ntawm electromagnetic induction los ntes cov khoom hlau. Thaum lub coil nyob rau hauv lub detector generates ib tug alternating magnetic teb, yog hais tias muaj ib tug hlau khoom nyob ze, cov dawb electrons nyob rau hauv cov hlau yuav induce tam sim no (eddy tam sim no) nyob rau hauv lub magnetic teb. Qhov eddy tam sim no yuav tsim ib qho chaw sib nqus ntawm qhov qub sib nqus, yog li hloov lub xeev ntawm qhov qub magnetic teb. Lub tshuab kuaj hlau txiav txim siab seb puas muaj cov khoom hlau nyob ze los ntawm kev kuaj xyuas qhov kev hloov no.
3. Kev sib raug zoo ntawm titanium thiab hlau ntes
Yog li, titanium puas yuav ua rau cov hlau ntes? Cov lus teb yog: nws nyob ntawm.
1>Purity thiab daim ntawv ntawm titanium
High-purity titanium tej zaum yuav tsis yooj yim nrhiav tau los ntawm cov hlau zoo tib yam detectors vim nws tsis zoo conductivity. Txawm li cas los xij, yog tias titanium muaj lwm yam impurities uas muaj zog conductivity, los yog nws daim ntawv (xws li hmoov, flakes) ua eddy tam sim no cov nyhuv yuav tshwm sim, ces nws yuav raug kuaj los ntawm hlau detectors.
2>rhiab heev ntawm hlau ntes
Lub rhiab heev ntawm cov hlau detectors kuj yog ib qho tseem ceeb, thiab txawv hlau detectors muaj ntau rhiab heev. Qee lub tshuab kuaj xyuas hlau muaj peev xwm tuaj yeem kuaj xyuas qhov tsis muaj zog hlau nplaum hloov pauv thiab yog li nrhiav pom muaj titanium. Qee lub ntsuas hlau tsis tshua muaj siab yuav tsis tuaj yeem ntes titanium.
3>Environmental yam
Electromagnetic cuam tshuam, av noo, kub thiab lwm yam hauv ib puag ncig ib puag ncig kuj tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov hlau ntes. Cov yam ntxwv xws li cov duab, qhov loj me, thiab tuab ntawm titanium yuav cuam tshuam rau kev kuaj pom. Feem ntau, cov ntaub ntawv titanium loj dua thiab tuab dua tuaj yeem pom tau yooj yim dua los ntawm cov khoom siv hlau, thaum cov khoom siv titanium me thiab nyias nyias yuav raug tsis quav ntsej los ntawm lub tshuab ntes.
4. Kev txiav txim siab hauv kev siv tswv yim
Hauv kev siv tswv yim, peb yuav tsum xaiv cov khoom siv hlau zoo raws li cov kev xav tau tshwj xeeb thiab cov xwm txheej. Piv txwv li, hauv kev kuaj xyuas kev ruaj ntseg hauv tshav dav hlau, txhawm rau kom muaj kev nyab xeeb, cov cuab yeej siv hluav taws xob siab siab feem ntau yog siv los kuaj xyuas txhua yam khoom siv hlau, suav nrog titanium. Hauv qee lub sijhawm uas tsis tas yuav tsum kuaj xyuas hlau, xws li kev khawb tawm sab nraud archaeological excavations los yog lub tsev khaws puav pheej pov thawj tiv thaiv, hlau detectors nrog qis rhiab heev tuaj yeem raug xaiv kom tsis txhob cuam tshuam tsis tsim nyog.
Yog li ntawd, seb titanium hlau yuav ua rau cov hlau ntes nyob ntawm ntau yam. Tom qab nkag siab txog cov hauv paus ntsiab lus thiab cov yam ntxwv ntawm titanium hlau thiab hlau ntes, peb tuaj yeem xaiv thiab siv cov cuab yeej hlau tshawb fawb ntau dua kom tau raws li qhov xav tau ntawm ntau lub sijhawm.
