A method of reducing crack propagation in an airfoil includes: providing an airfoil having a root spaced apart from a tip, spaced-apart leading and trailing edges, a suction side extending from the leading edge to the trailing edge, and an opposed pressure side extending from the leading edge and the trailing edge, supporting the airfoil against bending loads; and burnishing the airfoil using a burnishing element, so as to create at least one burnished section of residual compressive stress, the at least one burnished section being located adjacent the leading edge and spaced from the leading edge by an offset distance selected so as to avoid deformation of the leading edge.
A method of reducing crack propagation in an airfoil, comprising:
An airfoil for a gas turbine engine, comprising:
An apparatus for burnishing a gas turbine blade having a dovetail and an airfoil extending radially outward therefrom, the airfoil having opposed leading and trailing edges extending between a root and a tip, the apparatus comprising:
