| 摘 要： | 采用真空液相烧结法,在Q235钢表面制备三元硼化物基金属陶瓷覆层材料。利用扫描电镜、X射线衍射及能谱对其界面结构进行分析与表征。结果表明,在1 280℃温度下烧结,覆层材料具有良好的界面结构,其硬质覆层由三元硼化物硬质相和铁基黏结相组成,硬质相和黏结相分散均匀,覆层硬度（HRA）可达87;三元硼化物硬质覆层与钢基体间形成了良好的冶金结合,在界面处存在元素的扩散。

| Abstract: | A ternary boride cermet clad material was fabricated on the Q235 steel substrate by means of the vacuum liquid phase sintering technique.The microstructre and properties of the clad material were investigated with SEM,XRD and EDS.The results show that the clad material has good microstructre of the interface.The main composition of the clad layer is ternary boride base hard phase and ferrous base binder phase,which distribute uniformly in the layer.The surface hardness of the clad material reaches 87HRA.Favorable metallurgical coalescent has formed between the ternary boride cermet cladding and the steel substrate,with elements diffusion found at the interface. |
