Patent abstract
A blade includes an airfoil section extending between leading and trailing edges, first and second opposed sides each joining the leading and trailing edges, and an inner end and a free tip end. The airfoil section is formed of a metal-based material with a polymeric overcoat on at least one of the leading edge, trailing edge, first side and second side. The airfoil section includes an abrasive tip at the free tip end. The abrasive tip has a composition selected with respect to heat-induced delamination of the polymeric overcoat from frictional heat generated during rubbing of the abrasive tip.
