| 摘 要： | 通过间歇式抗高温氧化实验,建立了纯镍电铸层和N i-ZrO2纳米复合电铸层高温氧化动力学模型,分析了电铸层表面和横截面的形貌,测定了电铸层的组织结构。结果表明,N i-ZrO2纳米复合电铸层抗高温氧化性能明显优于纯镍铸层,复合电铸层表面生成的氧化膜晶粒细小且致密,并且该氧化膜较薄,产生的内应力较小,与复合电铸层的黏附性较好。

| Abstract: | The oxidation kinetics model of Ni and Ni-ZrO_2 composite electroforming deposit were established by batch cyclic oxidation.The surface and cross-section morphology of Ni and Ni-ZrO_2 composite electroforming deposit were analyzed,and the structure of composite electroforming deposit was determined.The results show that,comparing with Ni electroforming deposit,the composite electroforming deposit is apparently superior in high-temperature oxidation resistance,and the oxidation film of composite electroforming deposit has a smooth surface and compact microstructure.Due to thinner oxidation film and lower internal stress,the adhesion of the oxidation film to composite electroforming deposit is remarkably enhanced. |
