Abstract

The tip cap is fabricated from a plurality of chordwisely extending wafers 30, 32. The outermost wafer 30 being of an abrasive material such as silicon carbide embedded in a metal matrix. Convective cooling of the tip is established through the incorporation of laterally extending passages 34 between adjacent wafer elements. <IMAGE>
