摘要
A method is provided for repairing Z-notch wear surfaces on low pressure gas turbine engine turbine blades. The method is directed to turbine blades made of superalloy Inconel 713. Powdered Inconel 713 is welded to the Z-notch wear surface by directing an Nd:YAG laser beam upon the material. The laser beam is focused and traverses the wear surface in a stich-like pattern. The method allows Inconel 713 turbine blades to be repaired with the same material in a manner that does not generate cracking in the matrix material.
