5J1480 alloy yolondola 5J1480 superalloy Alloy yachitsulo-nickel Malinga ndi zinthu za matrix, imatha kugawidwa m'magulu a superalloy yochokera ku chitsulo, superalloy yochokera ku nickel ndi superalloy yochokera ku cobalt. Malinga ndi njira yokonzekera, imatha kugawidwa m'magulu a superalloy osinthika, superalloy yopangira ndi ufa wa metallurgy superalloy. Malinga ndi njira yolimbikitsira, pali mtundu wolimba wolimbitsa yankho, mtundu wolimbitsa mpweya, mtundu wolimbitsa kufalikira kwa oxide ndi mtundu wolimbitsa ulusi. Ma alloy otentha kwambiri amagwiritsidwa ntchito makamaka popanga zinthu zotentha kwambiri monga masamba a turbine, ma vane otsogolera, ma disc a turbine, ma disc a compressor okwera kwambiri ndi zipinda zoyaka za ndege, ma turbine a gasi a m'nyanja ndi mafakitale, ndipo amagwiritsidwanso ntchito popanga magalimoto amlengalenga, injini za rocket, ma reactor a nyukiliya, zida za petrochemical ndi zida zina zosinthira mphamvu za malasha.

kugwiritsa ntchito zinthu

5J1480 thermal bimetal 5J1480 alloy yolondola 5J1480 superalloy iron-nickel alloy superalloy imatanthauza mtundu wa zitsulo zochokera ku chitsulo, nickel ndi cobalt, zomwe zingagwire ntchito kwa nthawi yayitali kutentha kwakukulu kuposa 600 ℃ komanso pansi pa kupsinjika kwina; ndipo zili ndi mphamvu yapamwamba kwambiri kutentha kwambiri, kukana kwa okosijeni ndi dzimbiri, kutopa bwino, kulimba kwa kusweka ndi zina zambiri. Superalloy ndi kapangidwe ka austenite kamodzi, komwe kali ndi kukhazikika kwa kapangidwe kake komanso kudalirika kwa ntchito pa kutentha kosiyanasiyana.

Kutengera ndi makhalidwe omwe ali pamwambapa, komanso kuchuluka kwa ma superalloy, omwe amadziwikanso kuti "super alloys", ndi chinthu chofunikira chomwe chimagwiritsidwa ntchito kwambiri mu ndege, ndege, mafuta, makampani a mankhwala, ndi zombo. Malinga ndi zinthu za matrix, ma superalloy amagawidwa m'magulu awiri: iron-based, nickel-based, cobalt-based ndi ma superalloy ena. Kutentha kwa ntchito ya ma alloy otentha kwambiri okhala ndi iron nthawi zambiri kumatha kufika 750 ~ 780°C. Pazigawo zosagwirizana ndi kutentha zomwe zimagwiritsidwa ntchito kutentha kwambiri, ma alloy opangidwa ndi nickel ndi refractory metal-refractory amagwiritsidwa ntchito. Ma superalloy opangidwa ndi nickel ali ndi udindo wapadera komanso wofunikira m'munda wonse wa ma superalloy. Amagwiritsidwa ntchito kwambiri popanga zigawo zotentha kwambiri zamainjini a ndege ndi ma turbine osiyanasiyana a gasi. Ngati mphamvu yolimba ya 150MPA-100H ikugwiritsidwa ntchito ngati muyezo, kutentha kwakukulu komwe ma alloy a nickel amatha kupirira ndi >1100°C, pomwe ma alloy a nickel ali pafupifupi 950°C, ndipo ma alloy opangidwa ndi chitsulo ndi <850°C, kutanthauza kuti, ma alloy opangidwa ndi nickel ndi okwera kwambiri ndi 150°C mpaka pafupifupi 250°C. Chifukwa chake anthu amatcha alloy a nickel mtima wa injini. Pakadali pano, m'mainjini apamwamba, ma alloy a nickel amawerengera theka la kulemera konse. Sikuti masamba a turbine ndi zipinda zoyaka zokha, komanso ma disks a turbine komanso magawo omaliza a masamba a compressor ayamba kugwiritsa ntchito ma alloy a nickel. Poyerekeza ndi ma alloy achitsulo, zabwino za ma alloy a nickel ndi izi: kutentha kogwira ntchito kwambiri, kapangidwe kokhazikika, magawo osavulaza kwambiri komanso kukana kwambiri okosijeni ndi dzimbiri. Poyerekeza ndi ma alloy a cobalt, ma alloy a nickel amatha kugwira ntchito kutentha kwambiri komanso kupsinjika, makamaka pankhani ya masamba osuntha.

5J1480 thermal bimetal 5J1480 alloy precision 5J1480 superalloy Iron-nickel alloy Ubwino wa nickel alloy womwe watchulidwa pamwambapa ukugwirizana ndi zina mwa zinthu zake zabwino kwambiri. Nickel ndi kapangidwe ka cubic kozungulira nkhope komwe kali ndi chitsulo cholimba kwambiri.

Yokhazikika, yopanda kusintha kwa allotropic kuchokera kutentha kwa chipinda kupita kutentha kwambiri; izi ndizofunikira kwambiri posankha ngati chinthu cha matrix. Ndizodziwika bwino kuti kapangidwe ka austenitic kali ndi zabwino zambiri kuposa kapangidwe ka ferrite.

Nickel imakhala ndi mphamvu zambiri zamagetsi, siimasungunuka kwambiri pansi pa madigiri 500, ndipo sikhudzidwa ndi mpweya wofunda, madzi ndi madzi ena amchere kutentha kwa sukulu. Nickel imasungunuka pang'onopang'ono mu sulfuric acid ndi hydrochloric acid, koma imasungunuka mwachangu mu nitric acid.

Nickel ili ndi luso lalikulu lophatikiza zinthu, ndipo ngakhale kuwonjezera mitundu yoposa khumi ya zinthu zophatikiza sikuoneka ngati koopsa, zomwe zimapangitsa kuti pakhale mwayi wokonzanso zinthu zosiyanasiyana za nickel.

Ngakhale kuti mphamvu za makina a nickel yoyera si zolimba, pulasitiki yake ndi yabwino kwambiri, makamaka kutentha kochepa, pulasitikiyo siisintha kwambiri.

Makhalidwe ndi ntchito: kutentha pang'ono komanso kukana kwambiri. Sensa yotenthetsera kutentha muyeso wapakati komanso zida zowongolera zokha
