摘　　要：为提高Cu、Ag、La_(2)O_(3)的界面结合强度,通过化学镀工艺在Ag、La_(2)O_(3)粉末表面镀上均匀、完整和致密的Cu粉。采用热压烧结工艺制备出含有不同成分的三层和五层Ag/Cu/La_(2)O_(3)功能梯度材料,研究成分对两种功能梯度材料的显微组织、致密度和润湿性的影响。In order to improve the interfacial bonding strength of Cu,Ag,La_(2)O_(3),uniform,complete and compact Cu powder was coated on the surface of Ag and La_(2)O_(3) powder by electroless plating process.Three layers and five layers Ag/Cu/La_(2)O_(3) functionally graded materials with different compositions were prepared by hot pressing sintering process.The effects of compositions on the microstructure,density and wettability of the two functionally graded materials were stud-ied.

关 键 词：化学镀工艺 热压烧结工艺 功能梯度材料 致密度
