I-Cr3C2-NiCr ye-anti-oxidation ephezulu yezinga lokushisa nokumelana nokugqokwa
Incazelo
I-Cr3C2-NiCr iyinhlanganisela ephumelela kakhulu esetshenziswa kabanzi ezimbonini ezidinga izinga lokushisa eliphezulu nokumelana nokugqoka.Izinto ezisetshenziswayo zenziwe nge-chromium carbide (Cr3C2) ne-nickel-chromium (NiCr) alloy, okuyenza ibe yisixazululo esikahle sezinhlelo zokusebenza lapho kudingeka khona i-oxidation ephezulu yezinga lokushisa nokumelana nokugqokwa.
Amabanga e-KF-70, KF-69, kanye ne-KF-71 e-Cr3C2-NiCr aziwa ngokusebenza kwawo okuphakeme nokuqina ngaphansi kwezimo zezinga lokushisa eliphezulu.Usayizi wezinhlayiyana webanga ngalinye usukela ku-15-45 μm kanye no-20-53 μm, futhi ahlanganiswe futhi ahlanganisiwe ukuze kuqinisekiswe amandla amakhulu.
I-KF-70 Cr3C2-25NiCr inikeza ukumelana okuhle kakhulu ne-oxidation futhi igqoke ku-815 ℃.Kutuswa kakhulu izinhlelo zokusebenza ezisendaweni enezinga lokushisa eliphezulu ezidinga ukusebenza okuhlala isikhathi eside, njengama- blade ophephela kanye nezinjini ze- turbine yegesi.
I-KF-69 Cr3C2-20NiCr ingelinye ibanga elisebenza kahle elinikeza ukumelana okuphakeme ne-oxidation nokugqokwa ku-815 ℃.Ilungele ukusetshenziswa ezinhlobonhlobo zezicelo zokushisa okuphezulu, okuhlanganisa ukucutshungulwa kwamakhemikhali nokwelashwa kokushisa.
I-KF-71 Cr3C2-30NiCr iyibanga elisebenza kahle kakhulu elinikeza ukuqina okungcono kakhulu kunamanye amabanga emndenini we-Cr3C2-NiCr.Kutuswa kakhulu izinhlelo zokusebenza lapho ukuqina nokuqina kubalulekile, njengamathuluzi okumba uwoyela negesi, isikhunta esinezinga lokushisa eliphezulu, namathuluzi okusakaza.
Kafushane, umndeni we-Cr3C2-NiCr wemikhiqizo, okuhlanganisa i-KF-70, i-KF-69, ne-KF-71, iyisixazululo esifanelekile sezinhlelo zokusebenza ezidinga i-oxidation ephezulu yezinga lokushisa nokumelana nokugqoka.Le mikhiqizo ihlinzeka ngokuqina okuphakeme kanye nokuqina ngaphansi kwezimo zezinga lokushisa eliphezulu, okuyenza ilungele ukusetshenziswa ezimbonini ezifana ne-aerospace, ezezimoto, namandla.Ngokusebenza kwayo okuhle kakhulu nokuthembeka, imikhiqizo ye-Cr3C2-NiCr iyisinqumo esihle kakhulu kunoma ubani ofuna isisombululo sekhwalithi ephezulu, esihlala isikhathi eside sezinhlelo zokusebenza ezisezingeni eliphezulu.
