摘要:

采用X射线衍射(XRD), 扫描电镜(SEM)及能谱(EDAX)等方法, 研究了Ni-4.66Cr-5.87Co-7.54Mo-2.90W-4.97Ta-6.32Al合金在900℃和1000℃的高温氧化行为。结果表明, 合金氧化动力学曲线遵循氧化初期氧化增重速率较快, 氧化期间氧化动力学曲线呈波浪式变化, 且呈现氧化温度越高波浪式越明显的特征; 氧化300 h后合金表面氧化物膜分为2层, 外层氧化物为NiO、Ni₂Cr₂O₄、Ni₂CoO₄和CoTa₂O₆, 分布在外层的CoTa₂O₆抑制基体中元素Al向外扩散, 形成内层氧化物Al₂O₃。在氧化期间, 合金内部生成了内氮化物AlN, 且在合金内部AlN与Al₂O₃成规律性分布, 与外氧化膜相邻的为元素Al的内氧化物Al₂O₃区域, 远离外氧化膜的基体内部为元素Al的内氮化物AlN区域, 随氧化温度升高, 内氧化区和内氮化区的深度增加, 内氧化物和内氮化物的尺寸增大。

Abstract：

The oxidation behavior of a superalloy Ni-4.66Cr-5.87Co-7.54Mo-2.90W-4.97-Ta-6.32Al at 900℃ and 1000℃ in air has been investigated by means of TGA, XRD and SEM/EDAX. Results show that the oxidation rate in the initial stage is rapid, then with the oxidation time the oxidation weight gain tends to be smooth, but the oxidation kinetics curve for the superalloy later presents a wavy-like change and much obviously for the higher oxidation temperature. The oxide scales consist of two layers both at 900℃ and 1000℃. Of which , the outer layer is mainly composed of NiO、Ni₂Cr₂O₄、Ni₂CoO₄ and CoTa₂O_6,while the inner layer is a thin scale of Al₂O₃. The continuous oxide layer of Al₂O₃ is formed on the alloy surface to restrain the growth of oxide scale and decrease the oxidation rate. The precipitates of internal oxide (Al₂O₃) and internal nitride (AlN) formed in the superalloy after exposure for 300h at 900℃ and 1000℃; the internal oxidation zone forms on the surface of the superalloy just beneath the outer layer of the oxide scale, while the internal nitridation zone forms below the internal oxidation zone; with the increasing temperature the internal oxidation zone and internal nitridation zone became thicker, simultaneity the size of internal nitride and internal oxide increases.

Key words： metallic materials Ni-base superalloy isothermal oxidation kinetics curves internal oxidation internal nitridation
