Method for connecting TiAl-base alloy and Ti3SiC2 ceramic
The invention discloses a method for connecting a TiAl-base alloy and a Ti3SiC2 ceramic, which is characterized in that Al is used as a middle layer, and the TiAl-base alloy is connected with the Ti3SiC2 ceramic by an instantaneous liquid-phase diffusion connection technique. The method comprises the following steps: processing to obtain a test sample to be connected, and polishing and cleaning the surface to be connected; adding the Al middle layer between the TiAl-base alloy and the surface to be connected of the Ti3SiC2 ceramic to constitute an assembly part, wherein the Al middle layer can adopt Al foil or Al powder, or a metal Al layer is prepared on the connection surface of a certain matrix by hot spraying or magnetron sputtering to obtain the middle layer; and putting the assembly part into a vacuum hot press, heating to the connection temperature, and keeping the temperature for some time to perform diffusion connection. The method implements connection between the TiAl-base alloy and Ti3SiC2 ceramic, has the advantage of low energy consumption, and can easily implement industrialization.
