Zitholele ukusebenza okungenakuqhathaniswa kwe-GH44, i-nickel-based superalloy eklanyelwe ukuphumelela ezindaweni ezinezinga lokushisa eliphezulu. Iklanywe ngenhlanganisela enembile ye-nickel, i-cobalt, i-chromium, ne-molybdenum, i-GH44 inikeza amandla akhethekile, ukumelana ne-oxidation, nokuzinza kwe-thermal. Le alloy ethuthukisiwe yakhelwe ukumelana nezimo ezimbi kakhulu, okuyenza ibe ukukhetha okuhle kwe-aerospace, izinjini ze-turbine yegesi, ukucubungula amakhemikhali, nezinye izinhlelo zokusebenza ezinzima. Ngezakhiwo zayo eziphakeme zokukhasa nokuqhekeka, i-GH44 iqinisekisa ukusebenza okuthembekile nokuphila isikhathi eside ngisho nasemazingeni okushisa aphakeme. Izwa ukuthembeka nokuqina kwe-GH44 kuzinhlelo zakho zokusebenza ezibucayi zezinga lokushisa eliphezulu.

Isici somkhiqizo

I-GH44 iyisixazululo esiqinile se-Ni-Cr esiqiniswe ingxube yezinga lokushisa eliphezulu elikhubazekile nezinga lokushisa lesevisi elingaphansi kuka-900℃. Ilungele ukukhiqizwa kwegumbi elivuthayo le-aero-injini eyinhloko kanye nezingxenye zegumbi lomlilo likaphethiloli ezisebenza isikhathi eside ku-900 ℃ noma ngaphansi. I-alloy ingashiselwa nge-chlorine arc welding, i-spot welding, i-seam welding kanye ne-brazing, futhi ingahlanganiswa ne-1Cr18Ni9Ti, GH1140, GH3030 kanye ne-GH3039 alloys yokushisela. Izingxenye ezisebenza emazingeni okushisa aphezulu zingavikeleka ngokuphumelelayo nge-W-2 koqweqwe lwawo lwensimbi.

Isicelo somkhiqizo

I-GH44 isetshenziswa kakhulu ekwenzeni izingxenye zokushisa okuphezulu kwezinjini ze-aero-injini nama-turbines egesi, njengama-turbine blades, ama-vane aqondisayo, amagumbi avuthayo, njll. Iphinde isetshenziswe ekwenzeni izingxenye ezishisa kakhulu zokushisa ezinjini zamarokhethi nasembonini yenuzi. Ngaphezu kwalokho, iphinde isetshenziswe ekwenzeni izingxenye ezishisa kakhulu zezinjini zamarokhethi kanye nezingxenye ezishisa kakhulu embonini yamandla enuzi.
