zg40cr28ni48w5si2 ye sanfɛ-chromium-nickel-Tungsten-Silicon Heat- ye nɛgɛ ye min bɛ se ka kɛ ni nɛgɛ ye. A ka chromium hakɛ caman bɛ kɛ oxide protectif ye walasa ka fɛnw sɔgɔ. Nikɛri hakɛ caman bɛ a la ka a to a ka ɲi kosɛbɛ-Furakɛcogo sabatili ani sɛgɛn sɛgɛnbaliya. Tungsten ni silicon faralenw bɛ fanga bonya ni solid solution barika bonya ye.
Nin fɛn in bɛ fluidité ɲuman Di ka ɲɛsin casting ma complexe shapes ma ka ɲɛ. A bɛ castings profilés stable dimensionnellements (hakɛw labɔ) ni contours (kontoronw) jɛlenw ye.
Castings bɛ fanga ni microstructurel sabatili sabati funteni jugumanba la. U bɛ baara kɛ ni dannaya ye foro kuruw kɔnɔ, tuubuw la minnu bɛ yeelen bɔ, ani fɛnw minnu bɛ kɛ ka fɛnw sɔgɔ.
O yɔrɔw bɛ se ka thermomechanical stress gɛlɛnw muɲu k’a sɔrɔ u ma u yɛrɛ sɔgɔ walima ka u kari. U fana bɛ se ka surface oxydation ni spalling (sɔgɔli) kɛlɛ ka ɲɛ.
Baara kɛli ni nin fɛn in ye, o bɛ fɛn caman bɔ ɲɔgɔn na ni sanfɛla ye min ka bon ni sanfɛ-Furaya sabatili ye. A bɛ se ka kɛ sababu ye ka complexe-yɔrɔ minnu bɛ mɛn ka mɛn funteni baarakɛcogo la.
O bɛ dɔ bɔ ladonni jɔli la ani ka minɛnw bɛɛ lajɛlen nafa bonya. O kɔlɔlɔ bɛ se ka da a kan kosɛbɛ ani ka sɔrɔ ka caya-Furakɛcogo baarakɛtaw.
Nafa minnu bɛ sɔrɔ a la .
Exceptionnel haute-Furakɛcogo oksidan ni a sɔgɔli resistance .
Kɔrɔmu hakɛ caman (28 ɲɔgɔn) bɛ kɛ sababu ye ka chromium oxide layer dense dɔ sɔrɔ a sanfɛla la. Nin layini in bɛ baara kɛ i n’a fɔ balilan ɲuman oksizɛni ni fɛnɲɛnamafagalanw na, ka baarakɛwaati mɛnta sabati sanfɛ-Fɛɛrɛ sumalenw ni fiɲɛw la.
Fatigue thermal resistance outstand .
Nikɛri hakɛ min ka bon kosɛbɛ (48% ɲɔgɔnna%), o bɛ austenitic matrix structure sabati. O jɔcogo in bɛ fanga ni gɛlɛya caman Di funteni kɔrɔtalenw na, o bɛ Se ka Kɛ sababu ye ka 'sèn Bɔ a ka funteni ni nɛnɛ-yɔrɔw la minnu bɛ segin-ka-bɔ ni kari walima dɛsɛ ye k’a sababu Kɛ funteni degun ye.
A ka fisa ni a ka baarakɛcogo ɲuman ye ani a cogoya .
Alloy composition bɛ a to nɛgɛw bɛ wuli cogo ɲuman na, o bɛ a to nɔgɔmugu kɔnɔna gɛlɛnw falenni dafalen. O nafa ka bon kosɛbɛ walasa ka fɛnw dilan minnu bɛ kɛ ka ɲɛ, minnu ɲɛfɔlen don kosɛbɛ, minnu ɲɛfɔlen don kosɛbɛ, olu bɛ kɛ sababu ye ka dilancogo gɛlɛnw kɛcogo ɲɛ.
Superior High-Fɛɛrɛ fanga ni a ka resistance resistance .
Tungsten ni silicon bɛ fanga di kosɛbɛ aliji matirili ma ni solide solution barika bonya ye. O bɛ fɛn in ka krecɛnya fanga bonya kosɛbɛ Long-Term High-Semperature Loads kɔnɔ, o bɛ a to casting ka se ka dimension stabilité mara ani ka deformation (dafalen) kunbɛn funteni kɔrɔtalenw na.
Fɛn min bɛ kɛ ka fɛnw jira .
