摘 要：利用激光熔覆技术，在ZL104合金表面原位合成了TiCp/Al复合材料层。实验结果表明，经20 h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800nm；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20μm的TiC颗粒富集区和邻近基底部分有20 μm的稀释区。
Abstract: By using laser cladding， TiCp/Al composite has been insitu synthesized on the ZL104 alloy surface. During laser cladding， Al-Ti-C powder which have been milled for 20 h, could be synthesized completely as fine TiC particles which isabout 800 nm in size. Except that there is a rich zone of TiC about 20 μm thick at the top and a dilute zone of TiCp about 20 μm thick near substrate， the distribution of TiC particles is uniform in the cladding layer.
