AI Technical Summary

Problems solved by technology

These technical methods generally have problems such as high production cost, low efficiency, and uneven interfacial bonding strength.
At present, the domestic production of bimetallic composite materials mainly adopts rolling composite technology, but the interfacial bonding strength of this method is relatively low, and the performance of the prepared products meets the requirements of cutting-edge fields such as aerospace; the production of bimetallic composite materials abroad is mainly based in the United States. The Novelli composite method independently developed by Novelli is the main method. This method solves the situation of relatively low interface bonding strength of bimetallic composite materials, but the cost of preparing bimetallic composite products is too high, and only the temperature variables in the preparation process are controlled. Just spend hundreds of millions of dollars

Abstract

The invention discloses a preparation device and a preparation method of a bimetallic composite material. According to the method, the bimetallic composite material is prepared through solid-liquid composite casting, the bimetallic composite material is pressurized and subjected to pressure maintaining through a pressure system after casting of the bimetallic composite material is completed, and the interface bonding strength of the bimetallic composite material is further effectively improved; a casting mode of multi-system cooperation is adopted, so that the preparation of the bimetallic composite material is more efficient, simpler, more convenient and easier to operate, and potential safety hazards in the material preparation process are reduced; and a movable pressure mold cavity base structure is adopted and cooperates with a pressure system, so that quick demolding of the bimetallic composite material is realized, and the production efficiency is improved.

Description

technical field [0001] The present invention designs the technical field of preparation of bimetallic composite materials, and in particular relates to a preparation device and method of bimetallic materials for solid-liquid composite casting. Background technique [0002] With the continuous development of national high-tech, the performance requirements of materials are becoming more and more stringent, and the performance of a single material is difficult to meet the requirements of some fields. Therefore, bimetallic composite materials have become a research hotspot in recent years. Bimetallic composite materials combine the excellent properties of two metal materials, make up for the lack of performance of a single metal material, and have a unique "complementary effect", which can improve the performance of a single material due to individual performance defects. limited application status. [0003] For the preparation of bimetallic composites, the existing preparatio...
