| Abstract: | In ammonical silver nitrate solution, the research was done on silver-coated tungsten composite powders preparation which could be used in electrical contact manufacture by cementation of tungsten powder.The effect of processing conditions on the deposition of silver upon tungsten was investigated. The results indicated that the cementation was an effective and simple method to prepare well-covered silver-coated tungsten eomposite powders in uniform composition under proper conditions. |
