利用激光熔覆技术 ,在ZL10 4合金表面原位合成了TiCp/Al复合材料层。实验结果表明 ,经 2 0h混制的Al Ti C粉末 ,在激光熔覆过程中可以充分反应合成TiCp;在所形成的TiCp/Al复合材料层中 ,TiC颗粒尺寸细小 ,约 80 0nm ;经激光熔覆后的TiCp/Al复合材料层中TiC分布均匀 ,仅表层有约 2 0 μm的TiC颗粒富集区和邻近基底部分有 2 0 μm的稀释区 The laser cladding technique was used to synthesize TiCp / Al composite layer in-situ on the surface of ZL10 4 alloy. The experimental results show that the TiCp can be fully reacted during the laser cladding by the Al Ti C powder mixed at 20 h. The TiC particles in the formed TiCp / Al composite layer are small and about 80 0 nm. TiC cladding layer after TiCp / Al composite material distribution is uniform, only the surface layer of about 20μm TiC particle enrichment zone and adjacent to the base part of a 20μm dilution zone
