Abstract:Copper was induced into W powder by electroless, The compacts made from chemical copperplated W powder were infiltrated, and W/15 Cu composites were prepared. The microstructures of the composites were investigated by mean of scanning electron microscope Density, hermeticity and coefficient of thermal expansion were measured. After comparing microstructures and physical property of the W/15Cu made by conventional process, the effects of chemical copperplated W powder on properties of W/15Cu were discussed. The results showed that chemical copperplated W powder could improve the compactibility of W compact, the microstructure and the physical properties of W/15Cu composite. It is indicated that when the compact contains 2% copper, the properties of the material are fairly satisfactory.
