Isixazululo esiqinile se-GH3030 i-superalloy eqinisiwe iyisixazululo esiqinile esingu-80Ni-20Cr sakuqala esiqinisiwe.Inokwakheka kwamakhemikhali okulula, amandla okushisa agculisayo kanye nepulasitiki ephezulu engaphansi kuka-800 ℃, nokumelana okuhle ne-oxidation, ukukhathala okushisayo, ukunyathela okubandayo kanye nezakhiwo zenqubo yokushisela.
Ngemuva kokwelashwa kwesisombululo, i-alloy iyisigaba esisodwa se-austenite, futhi isakhiwo sizinzile ngesikhathi sokusetshenziswa.
Izingxenye ze-turbine combustor injini ezizosetshenziselwa umsebenzi ongaphansi kuka-800 ℃ nezinye izingxenye zezinga lokushisa eliphezulu ezidinga ukumelana ne-oxidation kodwa zithwale umthwalo omncane ongaphansi kuka-1100 ℃.
I-GH3030 inokusebenza okuqinile kokucubungula imfucuza eshisayo ebandayo, esetshenziselwa ukwenza amathuluzi ahlukahlukene amakhemikhali kanye nezinsiza.

• Isixazululo esiqinile esiqinisiwe i-superalloy, ukwakheka kwamakhemikhali okulula,
•Inamandla okushisa agculisayo kanye nepulasitiki ephezulu engaphansi kuka-800 ℃.
•Futhi inokumelana okuhle kwe-oxidation, ukukhathala okushisayo, isitembu esibandayo kanye nezakhiwo zenqubo yokushisela.
•Ngemuva kokwelashwa kwesisombululo, i-alloy iyisigaba esisodwa se-austenite, futhi isakhiwo sizinzile ngesikhathi sokusetshenziswa.
Inkambu yesicelo ye-GH3030:
I-alloy ibilokhu isetshenziswa enjinini ye-aero isikhathi eside, futhi isetshenziswa kakhulu ezingxenyeni ezivuthayo kanye ne-afterburner kanye nezingxenye zonqenqema ze-casing.
