摘要
单一金属材料的使役性能在航空航天、石油化工、风电、汽车等应用领域的局限性日渐凸显,而将具有两种不同物理、化学和力学性质的金属通过某种方式结合在一起形成双金属层状构件,从而使得双金属层状构件具备任一金属组元都无法比拟的性能优势,能够满足某些构件在极端环境下服役时所要求的高强高韧性、耐磨性和耐蚀性等性能,具有广阔的应用前景。双金属组元的化学成分和结构形态均不同,双金属层状构件的不同工作面存在力学性能差异,因而界面形态与结合性能成为双金属层状构件复合成形的关键。因此,本文基于双金属层状构件复合制造技术的研究现状,从双金属层状构件的界面结合过程的数值模拟和实验研究方面进行简要阐述,着重探讨工艺参数对双金属层状构件界面结合过程的影响规律,揭示界面形态和组织演变特征以及界面结合机理,指出现有双金属层状构件界面结合行为研究的不足,并展望双金属层状构件界面结合研究重点与发展趋势。
The limitation of single-metal material service performance in aerospace,petrochemical,wind power,automobile and other applications is increasingly prominent.Two kinds of metal materials with different physical and chemical properties are bonded to produce a bimetallic composited component.It has incomparable performance advantages of any metal component,and can meet the performance requirement including high strength and high roughness,wear resistance and corrosion resistance for some components serving in the extreme environments.The chemical compositions and structure morphologies of the bimetallic materials are different,leading to the performance difference in different surfaces of the bimetallic materials.Therefore,the interface morphology and performance of the interface between bimetallic components has become the key to produce the bimetallic composited components.In this paper,the numerical simulation and experimental study on the interface bonding of bimetallic component are reviewed based on the present situation of composited process of bimetallic layered component.The influence rules of processing parameters on the interface bonding process are emphasized.The morphologies and evolution characteristics in bonding interface as well as its bonding mechanism are clarified.Combined with the simulation and experimental results,the shortcomings of existing studies on the interface bonding behavior of bimetallic layered components are pointed out,and the research emphasis and trend are prospected.
