摘要(Abstract)：

将质量比为1∶1的TiB2硬质相和Co粘结相通过机械合金化球磨方式制备TiB2-50Co金属陶瓷复合粉末,将所获得的复合粉末通过超音速火焰喷涂技术在Q235钢基体表面制备TiB2-50Co金属陶瓷涂层,研究不同球磨时间粉末颗粒的组织结构,采用XRD分析TiB2-50Co金属陶瓷粉末与涂层的物相,研究涂层组织结构、耐磨损和耐熔融铝硅腐蚀性能。结果表明,TiB2硬质相与Co粘结相界面结合良好,当随着球磨时间的延长,Co粘结相塑变成长条形,复合粉末颗粒TiB2硬质相与Co粘结相呈层状结构。涂层组织较为致密,呈典型的层状结构;涂层的主要物相与粉末相同,主要为TiB2和Co两相;经过耐磨损实验发现,涂层具有良好的耐磨损性能。经过60 h熔融铝硅腐蚀后发现,涂层具有良好的耐熔融铝硅腐蚀性能。
