| Abstract: | FeCoCu prealloyed powder was prepared by coprecipitation method.The effects of the concentration of solution,temperature of coprecipitation,temperature and time of thermal decomposition on the yield and the particle size of the prealloyed powder were analyzed.The results show that good FeCoCu prealloyed powder can be prepared by coprecipitation method.The yield and the particle size increase with increasing the concentration of solution and the temperature of coprecipitation,respectively.The oxygen content of powder decrease and the particle size increase with increasing the temperature of thermal decomposition.The bulk samples sintered at 850℃ have high flexural strength,hardness and density.The welding intensity of FeCoCu prealloyed powder has satisfied the En13236—2001 standard on safety.The laser welding transition layer with FeCoCu prealloyed powder has higher welding intensity,better security and reliability than that of the certain overseas company. |
