| 摘 要： | 通过X射线衍射分析、光电子能谱仪和扫描电镜来分析等离子喷涂制备的碳化硼涂层的相组成和显微结构，用气孔率和显微硬度来表征涂层基本的性能．实验结果表明；对普通大气喷枪加以改进后，所得到的碳化硼涂层同国外采用高压等离子喷涂所得到的碳化硼涂层相比，具有更小的气孔率（3％～4％）和相接近的显微硬度（Hv＞28GPa）

| 关 键 词： | 碳化硼涂层 气孔率 显微硬度 |

| Abstract: | The phase composition and microstructure of boron carbide coatings by plasma spray wereinvestigated through X-Rad, XPS and SEM. The porosity and microhardness of the coatings werealso measured. The results showed that The plasma spray boron carbide coatings by using theimproved F4-MB plasma gun under atmospheric pressure had the lower porosity 3%~4% and theclosed microhardness Hv >28GPa compared with the coatings obtained under up to 2kpa argonpressure. |

| Keywords: | plasma spray boron carbide coating porosity microhardness |
