摘要
采用电弧离子镀沉积NiCrAlY涂层,探讨NiCrAlY涂层作为阻尼涂层的可行性并研究涂层的阻尼测试方法和阻尼特性。采用X射线衍射和扫描电镜等手段分别对涂层的物相结构、表面形貌以及化学成分进行了测试表征。而涂层阻尼的测试则采用动态机械分析仪和正弦扫频的方法进行,实验结果表明NiCrAlY涂层能明显提高样品的阻尼性能。
NiCrA1Y coating was deposited on 3Cr13 stainless steel substrates by an arc ion plating technique. This paper is to explore the feasibility of NiCrA1Y coating for the damping application and to characterize the method that may be used in defining the vibration features of the coatings. The phases of the NiCrAIY coating were determined by X-ray diffraction (XRD) technique. The surface morphology and chemical composition of the NiCrA1Y coating were analyzed by scanning electron microscope (SEM) and energy dispersive spectrometer (EDS), respectively. The damping properties were characterized by dynamic mechanical analyzer (DMA) and sine sweeps. Results show that the damping properties of the substrate are considerably improved by the NiCrA1Y coating.
