Method for preparing molybdenum copper part with complex shape

The invention discloses a method for preparing a molybdenum copper part with complex shape. The method comprises the following steps of: mixing an organic monomer and a cross-linking agent according to a certain volumetric ratio and adding into water to prepare 10 to 35 weight percent premixed solution; adding a certain proportion of molybdenum powder and a small amount of dispersing agent to prepare uniform and stable paste in which the volumetric ratio of the powder is 42 to 52 percent; adding a proper amount of initiator and catalyst and performing injection molding to obtain a billet with the shape of a required product; drying the billet and removing the adhesive; sintering at the temperature of between 1,200 and 1,450 DEG C to obtain a near-net-shape molybdenum frame, and infiltrating copper to obtain high-compactness molybdenum copper. The method has the advantages of simple process, high utilization ratio of material, low cost and high mechanical property and thermal property of product, is easy to realize large-batch direct preparation of the molybdenum copper part with complex shape and can be conveniently applied to the fields such as electronics, instruments, aviation and the like.
