I-GH3030 isisombululo esiluqilima esomeleziweyo i-superalloy sisisombululo esiluqilima sokuqala se-80Ni-20Cr esomeleziweyo.Inokwakheka kweekhemikhali ezilula, amandla awonelisayo obushushu kunye neplastiki ephezulu engaphantsi kwe-800 ℃, kunye nokumelana ne-oxidation elungileyo, ukudinwa kwe-thermal, isitampu esibandayo kunye neempawu zenkqubo ye-welding.
Emva kokunyanga isisombululo, i-alloy yi-single phase austenite, kwaye isakhiwo sizinzile ngexesha lokusetyenziswa.
Amalungu e-injini ye-injini yokutshisa i-injini ye-turbine aza kusetyenziselwa umsebenzi ongaphantsi kwe-800 ℃ kunye namanye amacandelo aphezulu obushushu afuna ukuxhathisa i-oxidation kodwa athwale umthwalo omncinci ongaphantsi kwe-1100 ℃.
I-GH3030 inomsebenzi owomeleleyo wokusetyenzwa kwenkunkuma eshushu ebandayo, esetyenziselwa ukwenza izixhobo ezahlukeneyo zeekhemikhali kunye nezincedisi.

• Isisombululo esiqinileyo esomeleziweyo i-superalloy, ukwakheka kweekhemikhali ezilula,
•Inamandla owanelisayo e-thermal kunye neplastiki ephezulu engaphantsi kwe-800 ℃.
•Kwaye inokumelana ne-oxidation elungileyo, ukudinwa kwe-thermal, isitampu esibandayo kunye neempawu zenkqubo ye-welding.
•Emva kokunyanga isisombululo, i-alloy yi-single phase austenite, kwaye isakhiwo sizinzile ngexesha lokusetyenziswa.
I-GH3030 indawo yesicelo:
I-alloy isetyenziswe kwi-injini ye-aero ixesha elide, kwaye isetyenziswa kakhulu kwi-combustor kunye neendawo ze-afterburner kunye ne-casing edge edge.
