I. Txoj Cai Golden ntawm Kev Xaiv Khoom
Kev nyab xeeb ntawm cov khoom cua sov pib nrog cov khoom siv. Cov ntsiab lus tseem ceeb suav nrog peb yam: kub tsis kam, thermal conductivity, thiab oxidation tsis kam.Cov khoom zoo tagnrho yuav tsum nyob ruaj khov ntawm qhov kub thiab txias, ua tau zoo hloov tshav kub, thiab tiv taus oxidation thiab corrosion. Piv txwv li, qee cov alloys ua tau zoo heev ntawm qhov kub thiab txias tab sis raug nqi; thaum cov hlau feem ntau yuav tsim nyog rau qhov qis - qhov kub thiab txias. Lub ntsiab lus tseem ceeb yog nrhiav qhov sib npaug raws li daim ntawv thov scenario.
II. Txoj Kev Txawj Ntse ntawm Kev Tswj Kub Kub
Kev tswj tsis tau qhov kub thiab txias yog qhov muaj kev nyab xeeb tshaj plaws rau cov cua sov. Cov qauv tsim niaj hnub no feem ntau siv ob qho kev nyab xeeb: ib qho yog qhov ntsuas kub sab hauv uas tsis tu ncua saib xyuas lub raj kub; lwm qhov yog qhov kev tswj xyuas ntse uas tau hloov kho lub zog los yog txiav tawm lub zog hluav taws xob thaum kub nce mus txog qhov tseem ceeb. Qhov kev tsim no tsis tsuas yog tiv thaiv overheating, tab sis kuj txuas ntxiv lub neej ntawm cov cua sov.
III. Kev Ua Yeeb Yam Zoo Tshaj Plaws
Kev nyab xeeb nyob hauv cov ntsiab lus. Kev tsim cov khoom cua sov yuav tsum coj mus rau hauv tus account thermal expansion coefficients, rwb thaiv tsev zog, thiab txhua yam muaj zog. Piv txwv li, siv lub corrugated raj tsim tuaj yeem nqus tau qhov kev ntxhov siab los ntawm thermal expansion thiab contraction; multi- txheej rwb thaiv tsev kho tuaj yeem tiv thaiv kom tsis txhob ntws; thiab cov qauv kev txhawb nqa tsim nyog ua kom muaj kev ruaj ntseg txawm tias nyob hauv ib puag ncig nrog kev vibrations. Txhua qhov nthuav dav yog qhov tseem ceeb rau kev nyab xeeb tag nrho.
