ALUMINUM FAN BLADE TIP WITH THERMAL BARRIER

摘要

A fan blade (16) for a gas turbine engine (10) is described. The fan blade (16) may comprise a body portion (58) formed from a metallic material, and it may include a suction side (64), a pressure side (62), a leading edge (66), a trailing edge (68), and a tip (70). A coating (74) may be applied to the tip (70), and the coating (74) may have a thermal conductivity of no more than about 10 watt per meter kelvin. The coating (74) may be a thermal barrier coating (77) comprising yttria-stabilized zirconia.
