摘要
双金属复合材料可以同时发挥两种材料的特性,满足复杂的应用性能需求。按照成形状态,双金属复合材料成形工艺可分为液-液复合、液-固复合和固-固复合三大类。本文总结了液-液复合及液-固复合成形的多种工艺路线,并着重介绍了应用前景良好的几种技术方案、发展水平及其适用范围。虽然双金属复合材料及制备方法已经取得长足进步,但目前复合材料市场仍然存在产业集中度不高、推广程度低的问题,后续仍然需要围绕理论研究、装备研究和应用研究开展相关工作。
The bimetal composite materials possess unique combinations of properties from two different metals,so they can meet the complex performance requirements in the application of materials.According to the forming state,the forming process of bimetal composite materials can be divided into three categories:liquid-liquid composite,liquid-solid composite and solid-solid composite.In this paper,various technological routes of liquid-liquid composite and liquid-solid composite are summarized,in which several forming process methods with good application prospects are introduced in detail,including the development level and application scope.Although great progress has been made in the bimetallic composite materials and preparation methods,such problems as low industrial concentration and low degree of promotion still exist in the composite material market,and the follow-up work still needs to be carried out focusing on theoretical research,equipment research and application research.
