1. the method for a vacuum scattering intermetallic compound for coupling TiAL realizes by following step:

  • one, before the diffusion connection mother metal surface is cleared up;

    Two, the diffusion intermediate layer is placed on the joint face of mother metal to be welded uniformly;

    Three, the weldment that will clamp places in the vacuum diffusion welding machine and heats, and is 1.33 * 10 in vacuum -3

    4.0 * 10 -3Spread connection under the Pa vacuum condition;

    Four, welding finishes to remove pressure when the back weldment is cooled to 100 ℃

    under former vacuum condition, when cooling to room temperature, takes out weldment;

    It is characterized in that diffusion connects the intermediate layer for putting hydrogen titanium or titanium alloy paillon foil, diffusion connects thickness 30~

    100 μ

    m in intermediate layer.
