| titleOfInvention | Method for preparing nano aluminum oxide dispersion enhanced copper-base composite material according to sol-gel method |
| abstract | The invention discloses a method for preparing a nano aluminum oxide dispersion enhanced copper-base composite material according to a sol-gel method, which belongs to the preparation field of a composite material. The method is characterized in that soluble salts of copper and aluminum or additional adding of carbon nanotube is used as a raw material to prepare sol, the sol is atomized and granulated in the presence of an atomizing drying agent to obtain nano-scale mixed powder, the mixed powder is calcined in an oxygen-free atmosphere at the temperature of 500 to 700 DEG C to obtain black powder, the black powder is reduced in a hydrogen atmosphere at the temperature of 300 to 600 DEG C to obtain nano alumina/carbon nanotube and copper composite powder, the composite powder is sintered in a hydrogen atmosphere at the temperature of 800 to 1100 DEG C after being molded in an isopressing manner to obtain the dispersed enhanced copper-base composite material with 0.1 to 3wt% of nano alumina. By adopting the method, the copper composite material which is high in compactness and uniform in dispersion phase distribution can be obtained; moreover, the process is simple, the production efficiency is high, and the method can be put in industrial production. |
