Connecting material and system for connecting silicon carbide material, connecting structure and application
The invention discloses a connecting material and system for connecting silicon carbide materials, a connecting structure and application. The connecting material comprises any one or a combination ofmore than two of Yb, Yb3Si2C2 and a Yb3Si2C2 coated silicon carbide composite materials. The invention also discloses the application of the Yb, Yb3Si2C2 or Yb3Si2C2 coated silicon carbide compositematerials in connection with a silicon carbide material. The invention further discloses a connection method of the silicon carbide material, a corresponding system adopted by the connection method and the finally obtained connection structure. According to the method, the characteristic of high-temperature decomposition of Yb3Si2C2 is utilized, and a generated liquid phase is beneficial to integrated sintering of silicon carbide of a connecting interface and silicon carbide of a matrix; the obtained silicon carbide connecting structure is high in bending strength and excellent in high-temperature resistance, oxidation resistance and corrosion resistance, and can be applied to extreme service environments such as aerospace and nuclear energy systems.
本发明公开了一种用于连接碳化硅材料的连接材料、系统、连接结构及应用。所述连接材料包括Yb、Yb3Si2C2、Yb3Si2C2包覆碳化硅复合材料中的任意一种或两种以上的组合。本发明还公开了Yb、Yb3Si2C2或者Yb3Si2C2包覆碳化硅复合材料于连接碳化硅材料中的用途。本发明还公开了一种碳化硅材料的连接方法，采用的相应的系统及最终获得的连接结构。本发明利用Yb3Si2C2高温分解的特性，产生的液相有利于连接界面碳化硅与基体碳化硅的一体化烧结；所获碳化硅连接结构的抗弯强度高，耐高温耐氧化耐腐蚀性能优良，可应用在航空航天及核能系统等极端服役环境中。
