摘要
为提高Cu、Ag、La2O3的界面结合强度,通过化学镀工艺在Ag、La2O3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/La2O3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.
Abstract
In order to improve the interfacial bonding strength of Cu,Ag,La2O3,uniform,complete and compact Cu powder was coated on the surface of Ag and La2O3 powder by electroless plating process.Three layers and five layers Ag/Cu/La2O3 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.
