ABSTRACT:
An improved blade tip with an abrasive coating is disclosed. The blade tip is included in a rotor blade which is rotatable with respect to a stationary surface. The tip has a contour which is effective for producing a normal loading component on the coating if the tip contacts the surface while rotating. In a specific form of the present invention, the tip comprises an end wall extending radially outwardly from the perimeter of the outer end of the rotor blade and a concave surface bounded by the end walls and extending radially inwardly therefrom.
