采用逐步熔融凝固法制备了WC－65Mn复合材料，用扫描电子显微镜观察试样的微观形貌和组织结构，并用IMAGETOOL软件分析不同试样的扫描图像，定量测定增强相WC颗粒的分布状况，同时测量材料的抗弯强度和硬度．研究证明电源功率和模具下降速率对增强相WC颗粒的分布状况和力学性能有重要的影响．电源功率应在5.5～7.5kW之间，模具下降速度为8～10mm／min．
The WC-65Mn composites were prepared by the stepwise melting and solidification method. The microstructure and morphology of the WC-65Mn composites were observed by scanning electron microscopy. Scanning images of different samples were analyzed by IMAGETOOL software to quantitatively determine the distribution of WC particles. Measure the flexural strength and hardness of the material. The results show that the power and die rate have an important influence on the distribution and mechanical properties of phase WC particles. Power supply should be between 5.5 ~ 7.5kW, mold drop speed of 8 ~ 10mm / min.
