摘要
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. ? 2023 Cailiao Daobaoshe/ Materials Review.
