5J1480 mwatsatanetsatane aloyi 5J1480 superalloy Chitsulo-nickel aloyi Malinga ndi matrix zinthu, akhoza kugawidwa mu chitsulo-based superalloy, faifi tambala-based superalloy ndi cobalt-based superalloy. Malinga ndi ndondomeko yokonzekera, zikhoza kugawidwa mu superalloy yopunduka, kuponyera superalloy ndi ufa zitsulo superalloy. Malinga ndi njira yolimbitsira, pali njira yolimbikitsira njira, mtundu wolimbitsa mvula, mtundu wa oxide wobalalika wolimbitsa ndi mtundu wolimbitsa thupi. Ma aloyi otenthetsera kwambiri amagwiritsidwa ntchito kwambiri popanga zida zotentha kwambiri monga ma turbine blade, ma vanes owongolera, ma turbine discs, ma turbine discs othamanga kwambiri komanso zipinda zoyatsira ndege, ma turbines apanyanja ndi mafakitale, ndipo amagwiritsidwanso ntchito popanga. zamagalimoto apamlengalenga, mainjini a rocket, zida zanyukiliya, zida za petrochemical ndi kutembenuka kwa malasha ndi zida zina zosinthira mphamvu.

ntchito zakuthupi

5J1480 matenthedwe bimetal 5J1480 mwatsatanetsatane aloyi 5J1480 superalloy chitsulo faifi tambala aloyi aloyi superalloy amatanthauza mtundu wa zinthu zitsulo zochokera chitsulo, faifi tambala ndi cobalt, amene angathe kugwira ntchito kwa nthawi yaitali pa kutentha pamwamba 600 ℃ ndi pansi pa kupsinjika maganizo; ndipo ali ndi mphamvu Yabwino kwambiri yotentha kwambiri, kukana kwa okosijeni wabwino komanso kukana dzimbiri, kutopa kwabwino, kulimba kwa fracture ndi zina zambiri. Superalloy ndi dongosolo limodzi la austenite, lomwe lili ndi kukhazikika kwadongosolo komanso kudalirika kwautumiki pa kutentha kosiyanasiyana.

Kutengera mawonekedwe omwe ali pamwambawa, komanso kuchuluka kwa ma alloy a superalloys, omwe amadziwikanso kuti "super alloys", ndi chinthu chofunikira chomwe chimagwiritsidwa ntchito kwambiri pamayendedwe apanyanja, mlengalenga, mafuta, makampani opanga mankhwala, ndi zombo. Malinga ndi zinthu za matrix, ma superalloys amagawidwa kukhala chitsulo, nickel-based, cobalt-based ndi superalloys ena. Kutentha kwa ntchito zazitsulo zokhala ndi zitsulo zotentha kwambiri zimatha kufika 750 ~ 780 ° C. Pazigawo zosagwira kutentha zomwe zimagwiritsidwa ntchito potentha kwambiri, ma alloys opangidwa ndi nickel ndi refractory zitsulo amagwiritsidwa ntchito. Ma superalloys opangidwa ndi nickel amakhala ndi malo apadera komanso ofunikira m'munda wonse wa superalloys. Amagwiritsidwa ntchito kwambiri popanga magawo otentha kwambiri a injini zandege ndi ma turbines osiyanasiyana amafuta am'mafakitale. Ngati mphamvu yokhazikika ya 150MPA-100H ikugwiritsidwa ntchito monga momwe zimakhalira, kutentha kwapamwamba kwambiri komwe zitsulo za nickel zingathe kupirira ndi> 1100 ° C, pamene nickel alloys ndi pafupifupi 950 ° C, ndi alloys-based alloys ndi <850 ° C, ndiko kuti. , ma aloyi opangidwa ndi faifi ndi apamwamba kwambiri ndi 150°C mpaka pafupifupi 250°C. Chifukwa chake anthu amatcha alloy nickel mtima wa injini. Pakalipano, mu injini zapamwamba, ma alloys a nickel amawerengera theka la kulemera kwake. Osati masamba a turbine okha ndi zipinda zoyaka, komanso ma turbine disks komanso magawo omaliza a masamba a kompresa ayamba kugwiritsa ntchito ma aloyi a nickel. Poyerekeza ndi ma aloyi achitsulo, ubwino wa nickel alloys ndi: kutentha kwapamwamba kogwira ntchito, mawonekedwe okhazikika, magawo osavulaza komanso kukana kwambiri kwa okosijeni ndi dzimbiri. Poyerekeza ndi ma aloyi a cobalt, ma aloyi a nickel amatha kugwira ntchito pansi pa kutentha kwambiri komanso kupsinjika, makamaka ngati masamba akusuntha.

5J1480 thermal bimetal 5J1480 precision alloy 5J1480 superalloy Iron-nickel alloy Ubwino womwe tatchulawa wa nickel alloy ndi wokhudzana ndi zina mwazabwino zake. Nickel ndi mawonekedwe a cubic omwe ali pakati pa nkhope ndi kwambiri

Khola, palibe kusintha kwa allotropic kuchokera ku firiji kupita ku kutentha kwakukulu; izi ndizofunikira kwambiri pakusankhidwa ngati matrix. Ndizodziwika bwino kuti mawonekedwe a austenitic ali ndi maubwino angapo kuposa kapangidwe ka ferrite.

Nickel imakhala ndi kukhazikika kwamankhwala, imakhala ndi oxidize pansi pa madigiri 500, ndipo samakhudzidwa ndi mpweya wofunda, madzi ndi njira zina zamchere zamchere pa kutentha kwa sukulu. Nickel amasungunuka pang'onopang'ono mu sulfuric acid ndi hydrochloric acid, koma mofulumira mu nitric acid.

Nickel ali ndi luso lapadera la alloying, ndipo ngakhale kuwonjezera mitundu yopitilira khumi ya ma alloying sikuwoneka magawo owopsa, zomwe zimapereka mwayi wowongolera zinthu zosiyanasiyana za faifi tambala.

Ngakhale makina a nickel oyera sali amphamvu, pulasitiki yake ndi yabwino kwambiri, makamaka pa kutentha kochepa, pulasitiki sichimasintha kwambiri.

Mawonekedwe ndi kugwiritsa ntchito: kutengeka kwa kutentha kwapakati komanso resistivity yayikulu. Thermal sensor muyeso yapakati kutentha ndi zida zowongolera zokha
