Zvikuru zvakabudirira zveindasitiri yezvemuchadenga hazvipatsanurike kubva mukusimudzira uye kubudirira mune tekinoroji yezvigadzirwa zvemuchadenga.Kukwirira kwepamusoro, kumhanya kwepamusoro uye kukwenenzvera kwendege dzehondo kunoda kuti zvimiro zvendege zvinofanirwa kuve nechokwadi chekusimba kwakakwana pamwe nekuomarara zvinodiwa.Zvishandiso zveinjini zvinoda kusangana nezvinodiwa zvekupisa tembiricha kuramba, tembiricha alloys, ceramic-based composite zvinhu ndizvo zvepakati zvinhu.

Simbi yemazuva ese inopfava pamusoro pe300 ℃, ichiita kuti isakodzere nharaunda dzine tembiricha yepamusoro.Mukutsvaga kwepamusoro simba rekushandura simba, yakakwirira uye yakakwirira yekushanda tembiricha inodiwa mumunda wekupisa injini simba.High-temperature alloys yakagadzirwa kuti ishande yakagadzikana patembiricha iri pamusoro pe600 ℃, uye tekinoroji inoramba ichishanduka.

High-temperature alloys zvinhu zvakakosha zveinjini yeaerospace, iyo yakakamurwa kuita iron-based high-temperature alloys, nickel-yakavakirwa nezvinhu zvikuru zvealloy.High-temperature alloys ave achishandiswa muaero-injini kubvira pazvakatanga, uye zvinhu zvakakosha mukugadzirwa kweinjini dzemuchadenga.Chiyero chekuita cheinjini chinoenderana zvakanyanya nedanho rekuita repamusoro tembiricha alloy zvinhu.Mune aero-injini dzemazuva ano, huwandu hwemhando yepamusoro-yekushisa alloy zvinhu zvinokwana 40-60 muzana yehuremu hwese hweinjini, uye inonyanya kushandiswa kune mana makuru-anopisa-ekupedzisira zvikamu: makamuri ekupisa, magiraidhi, turbine blades uye. turbine discs, uye nekuwedzera, inoshandiswa kune zvikamu zvakaita semagazini, zvindori, makamuri ekupisa uye miswe yemuswe.

(Chikamu chitsvuku chemufananidzo chinoratidza kupisa kwepamusoro alloys)

Nickel-based high-temperature alloys kazhinji inoshanda pa600 ℃ pamusoro pemamiriro ekumwe kushushikana, haingove nekunaka kwepamusoro-tembiricha oxidation uye corrosion resistance, uye ine simba repamusoro-tembiricha, simba rekukambaira uye simba rekutsungirira, pamwe nekuneta kwakanaka kuramba.Inonyanya kushandiswa mumunda wemuchadenga uye nendege pasi pemamiriro ekunze ekupisa, zvimiro zvemukati, senge mashizha einjini yendege, turbine discs, makamuri ekupisa uye zvichingodaro.Nickel-based high-temperature alloys inogona kupatsanurwa kuita akaremara epamusoro-tembiricha alloys, akakanda epamusoro-tembiricha alloys uye matsva emhando yepamusoro alloys zvinoenderana nemaitiro ekugadzira.

Iine kupisa-inodzivirira alloy kushanda tembiricha yakakwira uye yakakwirira, iyo inosimbisa zvinhu mualloy inowedzera uye yakawanda, iyo yakanyanya kuoma kuumbwa, zvichikonzera mamwe maalloys anogona kungoshandiswa muakakandirwa nyika, haigone kukanganiswa kupisa kupisa.Uyezve, kuwedzera kwealloying elements kunoita nickel-based alloys kusimba nekuparadzaniswa kwakakomba kwezvikamu, zvichikonzera kusafanana kwesangano uye zvivakwa.Kushandiswa kwehupfu metallurgy muitiro kugadzira yakakwirira tembiricha alloys, anogona kugadzirisa pamusoro matambudziko.Nekuda kwezvimedu zvidiki zvehupfu, kukurumidza kutonhora kwehupfu, kubvisa kusarurana, kuvandudza kupisa kwekushanda, iyo yekutanga yekukanda alloy mukupisa kunoshanda deformation yeyakakwira-tembiricha alloys, simba regoho uye kuneta zvinhu zvinovandudzwa, hupfu hwepamusoro-tembiricha alloy yekugadzirwa kwepamusoro. -simba alloys rakagadzira nzira itsva.
