초록

The present work illustrates the use of water-soluble cupric salts as ingredients of binder for injection molding of $W-10 wt\%$ Cu. Parts produced are dense, homogeneous and have good surface finish, compared to those produced using conventional binder system. This new binder system provides also process-simplification benefit. $CuCl_2\;and\;Cu(NO_3)_2$ with the purity of $98\%$ was selected for this study. Rapid sintering process involving thermal decomposing was successful in densification for 1h. Final density that is about $93\%$ of theoretical value could be obtained, and are distinguishable from conventionally processed W-Cu composites.
