Thaum muab cov khoom siab tshaj -kev ua tau zoo alloys rau qhov chaw huab cua, Nimonic 90 thiab Inconel 718 feem ntau xav txog. Ob leeg ntawm cov npib tsib xee no -raws li superalloys yog siv nyob rau hauv siab - daim ntawv thov kub xws li aerospace, gas turbines, thiab industrial gas compressors. Txawm li cas los xij, lawv tau ua kom zoo rau cov yam ntxwv sib txawv thiab kev siv cov xwm txheej. Nkag siab txog lawv qhov sib txawv tseem ceeb hauv kev sib xyaw, cov khoom siv kho tshuab, thiab cov ntawv thov yog qhov tseem ceeb rau kev txiav txim siab kev yuav khoom.
NIMONIC® alloy 90 yog dab tsi?
NIMONIC® alloy 90 (UNS N07090/W. Nr. 2.4632) yog nickel wrought-chromium-cobalt puag alloy ntxiv dag zog los ntawm kev ntxiv ntawm titanium thiab txhuas. Nws tau raug tsim los raws li lub hnub nyoog -cov tawv tawv creep- tiv taus alloy rau kev pabcuam ntawm qhov kub txog li 920℃(1688℃F.It tuaj yeem ua tiav rau ntau yam khoom siv, suav nrog cov ntawv, coils, raj, rods, thiab cov xov hlau.
Puas yog Inconel 718 nyuaj rau tshuab?
Cov npib tsib xee no-raws li superalloy, ib qho tseem ceeb hauv kev siv aerospace, muaj lub zog zoo heev thiab ua haujlwm kub heev-tab sis cov khoom qub no ua rau nws tsis yooj yim rau tshuab. Inconel 718 nyiam ua haujlwm- tawv sai, ua kom sov huab cua ntawm lub cuab yeej-workpiece interface, thiab ua kom cov cuab yeej siv nrawm dua.
