Nano-structured fan airfoil sheath

摘要

A method of forming a sheath (32) for a fan airfoil having a leading edge (36), a trailing edge (38), a tip (40), a root (42), a suction side (44) and a pressure side (46) includes electroplating a nano-structured material to form a sheath (32) with a solid portion (48) to wrap around the leading edge (36) and first and second flanks (50,50) to secure the solid portion (40) to the pressure side (44) and the suction side (46) of the airfoil.
