Iimpawu ze-Inconel 718
I-Inconel 718 yimvula eyenza lukhuni i-nickel-based superalloy enokumelana nobushushu obuphezulu be-corrosion.Ngokuqhelekileyo isetyenziswa kwishishini le-aerospace, i-Inconel 718 inika amandla aphakamileyo omatshini wokushisa kunye ne-ductility egqwesileyo ukuya kuthi ga kwi-704 ° C / 1300F.Ayinamagnetic kwindalo.
I-nickel-based superalloy 718 inokumelana kakuhle ne-oxidation kunye nezinye iintlobo zomhlwa kwi-injini yejethi yendawo kunye nezicelo ze-injini yegesi esekelwe emhlabeni.Yeyona nto ifanelekileyo kwizicelo ezifuna ukuchasana okugqwesileyo kunye noxinzelelo lokuqhekeka kwe-corrosion (ukuya kuthi ga kwi-982 ° C okanye i-1800F).I-alloy 718 inika ukhuseleko olupheleleyo kwi-pitting kunye ne-crevice corrosion kwi-sulfides, i-chlorides, i-carbon dioxide kunye nezinye iindawo ezibuhlungu.
I-Inconel 718 ineempawu ezintle ezibanzi kuluhlu lobushushu ukusuka -253 ukuya kuma-700 °C, amandla esivuno angaphantsi kwe-650 °C kwinqanaba lokuqala kwi-superalloy egqwethekileyo, kwaye inokumelana nokudinwa okuhle, ukumelana nemitha, ukuxhathisa kwe-oxidation, ukuxhathisa ukubola, kunye nokusebenza kakuhle.Ukusetyenzwa kwentsebenzo, ukusebenza kwewelding kunye nozinzo lwexesha elide lombutho, inokuvelisa iindawo ezahlukeneyo ezineemilo ezintsonkothileyo, kwaye isetyenziswe ngokubanzi kuluhlu lobushushu obungasentla kwi-aerospace, amandla enyukliya, kunye namashishini epetroleum.
I-Inconel 718 alloy yimvula eyenza lukhuni i-nickel-chromium-iron alloy equlethe i-niobium kunye ne-molybdenum.Inamandla amakhulu, ukuqina okuhle kunye nokuxhathisa umhlwa kwindawo ephezulu kunye nesezantsi yobushushu obungaphantsi kwe-650 ℃.Esi simo sinokunyangwa isisombululo okanye imvula iqiniswe.
1. Kulula ukusetyenzwa
2. Amandla aphezulu okuqina, amandla okudinwa, amandla okurhubuluza kunye namandla okugqabhuka ku-700℃
3. 1000℃ ukuxhathisa okuphezulu kwe-oxidation
4. Uzinzile kwiikhemikhali kwiqondo lokushisa eliphantsi
5. Ukusebenza kakuhle kwe-welding

I-Inconel718 yeeNdawo zeSicelo seMveliso
Ngenxa yamandla alo obushushu obuphezulu kwi-700 ° C, ukuxhathisa okugqwesileyo kwe-corrosion kunye nokucutshungulwa ngokulula, kunokusetyenziswa ngokubanzi kwiimeko ezahlukeneyo ezifunwa kakhulu.
1. I-injini yomphunga
2.I-rocket yamafutha e-Liquid
3.Cryogenic engineering
