| 摘 要： | 利用钨极氩弧熔敷预涂在碳钢表面的钛铁和石墨粉末能够在碳钢表面获得性能优异的TiC增强涂层.预涂粉末Ti、C元素配比及含量对增强相的数量、形态和分布方式有重要影响：一方面，随着预涂粉末中含碳量的增加，熔敷层中Fe2Ti有害相降低，但出现了极少量的石墨相；另一方面，熔敷层中原位合成TiC增强相的含量增加，颗粒尺寸也随之增加，TiC颗粒的树枝状分布形态也由细枝状向粗枝状转化.

| Abstract: | The in-situ TiC reinforced composites coating was obtained by prepared ilmenite and graphite powder on carbon steel through metallurgical interaction in tungsten arc welding. The proportion of Ti and C has an important influence on the volume and contribution of in-situ TiC. The results showed that with increasing carbon contents, the Fe2Ti phase was reduced, while a very small amount of graphite phases appeared. The particle size increased with an increasing in-situ TiC content, and the dendrite distributi... |
