ABSTRACT:
A rotary seal member, such as a gas turbine engine blade, is provided with an improved surface layer which has an elastic modulus matched with the elastic modulus of a substrate of the member. Also, the surface layer does not form a brittle intermetallic with the substrate at an intended operating temperature. In one form, the surface layer includes abrasive particles adapted to inhibit chemical reaction with the layer material. One specific example is a Ti-alloy substrate having a metallurgically bonded layer based on Nb, and including cubic boron nitride abrasive particles coated with cobalt entrapped in the layer.
