摘要: 研究了铁基合金GH1140(%:0.08C、21.60Cr、37.42Ni、2.31 Mo、1.63W、0.44Al、0.91Ti)、镍基合金GH4098(%:0.02C、18.52Cr、5.92Co、5.81W、3.96Mo、2.74Al、1.19Ti、0.10Fe)和钴基合金GH5605(%:0.10C、19.92Cr、10.55Ni、15.16W、1.77Mn、0.52Fe)在750~950℃100h的静态氧化行为。结果表明,在750~900℃,3种合金中GH4098抗氧化性最佳,GH1140最弱;950℃,GH5605抗氧化性最佳,GH1140最弱。GH1140的氧化膜组成主要为Cr2O3+少量(Fe+2Cr2O4),GH4098为(Cr2O3+NiCr2O4)+少量NiO,GH5605为Cr2O3+Co3W+ CrMn2O4

Abstract: Statical oxidation behavior of ferrous-base alloy GH1140(%:0.08C、21.60Cr、37.42Ni、2.31 Mo、1.63W、0.44Al、0.91Ti),nickel-base alloy GH4098(%:0.02C、18.52Cr、5.92Co、5.81W、3.96Mo、2.74Al、1.19Ti、0.10Fe) and cobalt-base alloy GH5605(%:0.10C、19.92Cr、10.55Ni、15.16W、1.77Mn、0.52Fe) at 750~950 ℃ for 100 h has been studied. Ruesults showed that at 750~900℃,the oxidation-resisting quality of GH4098 was optimum and that of GH1140 was lowest in the 3 kinds of superalloys at 950 ℃,the oxidation-resistant quality of GH5605 was optimum and that of GH1140 was lowest likewise.The main ingredient of oxidation film for GH1140 was Cr2O3+a little (Fe+2Cr2O4), that for GH4098 was(Cr2O3+NiCr2O4)+ a little NiO,and that for GH5605 was Cr2O3+Co3W+CrMn2O.
