Abstract

The invention relates to a method for preparing a copper-based composite material. Copper powder and zirconium carbide powder are used as raw materials, and ball-milled by using a ball mill, the ballgrinding medium is a zirconium carbide ball, and a high-purity argon gas is filled into a ball milling tank in the ball milling process and is sealed. After ball milling, the mixed powder is placed ina graphite mold and sintered in a vacuum hot-pressing furnace to keep constant temperature and apply pressure at the highest sintering temperature. After the sintering is finished, the pressure is released and the furnace is cooled to room temperature. The prepared material is the copper-based composite material provided by the invention. The method provided by the invention is simple, and the prepared copper-based composite material has an excellent wear resistance performance and easy processing performance, and is suitable for preparing components in the environment under impact and easy wearing conditions.

Description

technical field [0001] The invention relates to the field of material synthesis and preparation, in particular to a method for preparing a copper-based composite material. technical background [0002] Copper materials have good electrical conductivity, thermal conductivity and easy processing properties, and are widely used in components such as bearings, bushes, gears, joints and friction. However, due to the low strength and poor wear resistance of pure copper materials, the service life is short and the scope of use is limited. In some specific fields, it is necessary to improve the mechanical properties and mechanical properties of pure copper materials while retaining the metallic properties. [0003] Zirconium carbide is a high-hardness material with metallic properties, and its electrical conductivity can reach 2.3×10 4 S / cm, the electrical conductivity is equivalent to that of metals, and it has a good application prospect in improving the mechanical properties of...
