Abstract
The present disclosure relates generally to a fan blade assembly. In an embodiment, the fan blade assembly includes an airfoil having a forward edge covered by a sheath. The airfoil and the sheath are made from dissimilar conductive materials. A nonconductive coating is applied the an airfoil contact surface of the sheath before it is bonded to the leading edge of the airfoil.
