SHS AND COMPACTION OF TITANIUM DIBORIDE-Cu SYSTEM COMPOSITES

TiB₂-Cu composite is higH₂elect ric composite with high-intensity , but the preparation of dense TiB₂-Cucomposite is quite difficult because of the bad wettability of TiB₂-Cu. The influence of different materials systems onthe characteristics (temperature , speed of combustion , production , etc. ) of the production by SHS (Self-propagating High-temperature Synthesis) was investigated. Based on these , the SHS/ QP technique was developed and usedfor the preparation of dense TiB₂-Cu composite. The additives of Mo and Fe improve the wettability , make theproduct s more uniform and decrease the pore ratio and the particle size.
