Inconel 718 Ibiranga
Inconel 718 ni imvura ikomera nikel ishingiye kuri superalloy hamwe nubushyuhe bwo hejuru bwo kwangirika.Bikunze gukoreshwa mu nganda zo mu kirere, Inconel 718 itanga imbaraga zubushyuhe bwo hejuru hamwe nubushyuhe buhebuje bugera kuri 704 ° C / 1300F.Ntabwo ari magnetiki muri kamere.
Nickel ishingiye kuri superalloy 718 ifite imbaraga zo kurwanya okiside hamwe nubundi bwoko bwa ruswa muri moteri yindege hamwe nubutaka bwa gaz turbine.Nibikoresho byiza kubisabwa bisaba kurwanya cyane kunyerera no guhangayika kwangirika (kugeza kuri 982 ° C cyangwa 1800F).Alloy 718 itanga uburinzi bwuzuye bwo gutobora no kwangirika kwangirika muri sulfide, chloride, dioxyde de carbone nibindi bidukikije.
Inconel 718 ifite ibintu byiza byuzuye mubushyuhe bwa -253 kugeza kuri 700 ° C, imbaraga zumusaruro uri munsi ya 650 ° C ziza kumwanya wa mbere muri superalloys yahinduwe, kandi ifite umunaniro mwiza, kurwanya imishwarara, kurwanya okiside, kurwanya ruswa, no gukora neza.Imikorere yo gutunganya, imikorere yo gusudira hamwe nigihe kirekire cyumuteguro uhamye, irashobora gukora ibice bitandukanye bifite imiterere igoye, kandi yakoreshejwe cyane mubushuhe bwavuzwe haruguru mubirere, ingufu za kirimbuzi, ninganda za peteroli.
Inconel 718 alloy ni imvura igwa nikel-chromium-fer alloy irimo niobium na molybdenum.Ifite imbaraga nyinshi, gukomera no kurwanya ruswa ahantu harehare kandi hake munsi ya 650 ℃.Iyi leta irashobora gukemurwa igisubizo cyangwa imvura igakomera.
1. Biroroshye gutunganya
2. Imbaraga zikomeye, imbaraga z'umunaniro, imbaraga zo gukurura n'imbaraga zo guturika kuri 700 ℃
3. 1000 resistance irwanya okiside nyinshi
4. Imiti ihamye mubushyuhe buke
5. Imikorere myiza yo gusudira
