摘要: 综述了激光熔覆陶瓷及其复合涂层的组织特征与性能.分析了涂层区、结合区组织的形成机制及陶瓷金属复合涂层中陶瓷相的溶解行为,阐述了熔覆工艺特别是扫描速度及搭接处理对熔覆层组织的影响.Abstract: The structure characteristics and the properties of laser clad ceramic and its composite coatings are reviewed. The form mechanism of clad layer and bonding zone structure and the dissolved behavior of the ceramic phase in ceramic metal composite coatings are analyzed. The effect of the cladding technologies,especially the scanning speed and the lapping treatment on the structure of clad coatings is expounded.
