| 摘 要： | 在超细陶瓷涂料中分别添加了不同含量的纳米金属镍粉,用扫描电镜观察了纳米金属/超细陶瓷涂料中纳米颗粒的尺寸和微观形貌以及在涂层中的分布情况;通过摩擦实验评价了涂层的耐磨损性能。结果表明:合理控制各工艺过程,用流涂法获得了纳米镍粉/超细高温无机陶瓷涂层,涂层中的纳米颗粒趋于靠近涂层/基体界面处分布;在900℃保温过程中,涂层中纳米颗粒没有明显长大;添加纳米金属镍粉可以明显提高涂层的耐磨损性能,随纳米镍粉含量的增加,涂层的耐磨损性能提高。

| Abstract: | Scanning electron microscope was used to observe the size,microstructure and distribution of the nano nickel particles added in the ultra-fine ceramic coatings.Wear resistance of the coating was evaluated through friction experiment.The results showed that nano nickel powder/high-temperature ultrafine ceramic coating was prepared by flow coating under the condition of reasonable control of the technological process.Nano particles in the coating distributed near the interface between the coating and substrat... |
