| 摘 要： | 在Ti6A14V表达通过激光熔覆工艺原位合成TiC/Ti金属基复合材料涂层，其基体组织结构随表层预置合金粉末成分的变化而改变，采用单摆划痕装置测试原位合成TiC/Ti复合材料涂层的冲击磨粒磨损性能，结果表明，与基材Ti6A14V相比复合材料激光熔覆层的抗冲击磨粒磨损性能提高了2倍，且随表层预置粉末中Cr3C2含量的增加，反应生成的TiC含量增加，涂层抗冲击磨料磨损性能提高。 |
| 关 键 词： | 原位合成 冲击磨料磨损 TiC／Ti复合材料 激光熔覆 |

| Abstract: | TiC/Ti metal matrix composite coating was in ?situ synthesized by laser cladding process on Ti6A14V alloy. The matrix structure of composite coating changes with different composition of prepared alloy powders. The impact abrasive behavior of composite coating has been investigated using a single pendulum scratch device. The results show that the impact abrasive resistance of composite coating is three times that of T16A14V matrix alloy, and the content of TiC in composite coating is increased with the content of Cr3C2 in prepared alloy powders increased, resulting in the increase of the impact abrasive resistance performance of composite coating. |
| Keywords: | in - situ synthesis laser cladding composite impact abrasive behavior |
