| 摘 要： | 以TiC粉和高铬铸铁(high chromium white iron,HCWI)粉为原料通过热压烧结制备了TiC增强高铬铸铁(TiC/HCWI)复合材料,研究了TiC增强相对HCWI的微观组织、物相组成、力学性能、抗磨性能的影响。结果表明,添加的TiC颗粒抑制了HCWI材料中M7C3 (M=Fe,Cr)碳化物的生长,细化了HCWI的微观结构。随着TiC含量的增加,TiC/HCWI复合材料的洛氏硬度、断裂韧性、弯曲强度和抗磨性能增加。利用X射线衍射和电子扫描电镜分别对复合材料的物相组成和微观结构进行了表征;对复合材料的增强机制进行了分析。

| Abstract: | High chromium white iron composites reinforced with TiC (TiC/HCWI) were prepared by hot pressing of TiC and high chromium white iron (HCWI) powders. The effects of TiC on microstructure, phase composition, mechanical properties and wear resistance of TiC/HCWI were studied. Results showed that the growth of M7C3(M = Fe, Cr) in HCWI was effectively inhibited by TiC grains, refining the microstructure of HCWI. Rockwell hardness, fracture toughness, flexural strength and wear resistance of the fabricated composites increased with increasing the content of TiC. X-ray diffraction analysis and scanning electron scope were used to characterize the phase composition and microstructure of composites. The reinforcing mechanism of TiC was analyzed. |
