The plurality of blades each has a leading edge and a trailing edge radially outside of the leading edge. The plurality of blades each has circumferentially oppositely facing first and second surfaces each extending between respective leading and trailing edges. The plurality of blades each has a material bonded at the leading edge and over only a portion of the exposed surface area of one of the first and second surfaces.
