More Information
Summary:The present invention relates to a self-spreading reaction connection method of TiAl alloy and TiB2 metal ceramics, and relates to a welding method of TiAl alloy and TiB2 metal ceramics. Said method includes the following steps: using high-frequency electromagnetic field to preheat TiAl alloy and TiB2 metal ceramics; at the same time of applying high-frequency electromagnetic field applying axial pressure of 30-60MPa to overlapped alloy and metal ceramics and making the powder pressed briquette sandwiched between alloy and metal ceramics be ignited by high-frequency electromagnetic field and produce self-spreading reaction so as to implement connection of alloy and metal ceramics. The described powder pressed briquette is made up by uniformly mixing powders of Ti,Al,C,Ni and Mo and pressing them.
