| 摘 要： | 利用等离子熔覆技术在A3钢表面制备了一层与基体呈冶金结合的、性能良好的非晶纳米晶复合涂层.涂层有非晶相和纳米相组成,根据衍射峰的半高宽,计算出铁基涂层中平均晶粒尺寸为22～24nm.对涂层进行XRD、SEM、EDS、TEM和DSC分析,并利用显微硬度计和电化学工作站研究涂层的硬度和耐蚀性能,研究表明所制备的铁基涂层具有良好的性能.

| Abstract: | An amorphous nanocrystalline alloy coating was prepared on A3 steel by plasma cladding. The structure of coatings was composed of amorphous phase and nanocrystalline. According to half-high width of diffraction patterns, the average particle size of iron-based alloy coatings was about 22-24nm. The performance of the coatings was studied using XRD, SEM, EDS, TEM, DSC, microhardness device and electrochemical workstation. The study results show that ironbased coating, is a good performance. |
