20100297468 | METHODS OF JOINING AND MATERIAL DEPOSITION FOR A WORKPIECE WITH A WORKPIECE AREA MADE FROM A TITANIUM-ALUMINIDE ALLOY - The invention concerns a method to create fusion-integrated joints of workpieces, in which a workpiece area formed on a workpiece made from a TiAl alloy and a workpiece area formed on another workpiece made from a TiAl alloy or a different high temperature material are joined in a joint area using a joining additive, where the joining additive contains at least one of the elements gallium and indium. The invention also concerns a method to create a material deposit on a workpiece, in which a deposit material is applied to a workpiece area made from a TiAl alloy, where a fusion-integrated joint is produced between the deposit material and the workpiece area, where the deposit material contains at least one of the elements gallium and indium and a filler material. | 11-25-2010 |
