Nyob rau hauv siab - muaj kev pheej hmoo ntawm kev lag luam cua sov thiab aerospace ib puag ncig, koj xaiv cov ntaub ntawv txiav txim siab txog lub sijhawm ntev - kev vam meej lossis kev puas tsuaj loj. Rau kev yuav cov thawj coj thiab cov engineers, qhov teeb meem loj tshaj plaws thaum muab khoomGH3030 npib tsib xee-chromium alloy tuavsuav nrog:
Coarse grain qauv:Tsawg- cov txheej txheem melting kawg ua rau cov nplej ntxhib thiab nkig, ua rau tawg hauv qab thermal qaug zog.
Impurity segregation:Cov ntsiab lus (sulfur, lead) seem hauv cov hlau tuaj yeem ua rau lub zog poob qis ntawm800 degree.
Hloov Risk:Siv cov ntaub ntawv tsis muaj ntawv pov thawj uas tsis ua raws li cov khoom siv metallurgical meej ntawmNimonic 75 / Alloy 75.
NtawmGnee Alloy, peb tshem tawm cov kev pheej hmoo no. Raws li cov chaw tsim khoom Tier-1 nplooj siab, peb ua kom zoo duaHWM 3030siv ob lub tshuab nqus tsev vacuum:Vacuum Induction Melting (VIM) + Electroslag Remelting (ESR)los xyuas kom meej nws cov qauv kev ncaj ncees.

GH3030 thiab GH3044 yog npib tsib xee-chromium raws li cov kuab tshuaj ntxiv zog superalloys, dav siv nyob rau hauv siab -kub aerospace thiab industrial teb. Ob leeg muaj kev tiv thaiv oxidation zoo heev, tab sis GH3044 muaj qhov kub thiab txias ua haujlwm ntau dua li GH3030.
Dab tsi yog cov khoom ntawm GH3030?
GH3030 yog ib qho kev daws teeb meem ntxiv dag zog rau siab - kub alloy, feem ntau yog tsim los ntawm npib tsib xee (Ni) thiab chromium (Cr), nrog rau cov tshuaj lom neeg yooj yim. Nws qhov piv txwv yog 80% npib tsib xee thiab 20% chromium.
