Blade outer air seal having partial coating

摘要

A blade outer air seal member (32) includes a body (40) that extends between two circumferential sides (42), axially between a leading edge (44a) and a trailing edge (44b), and between a gas path side (46a) and a radially outer side (46b) opposite the gas path side (46a). A ceramic coating (48) is initially disposed on a portion (50) of the gas path side (46a) outside of a blade rub area (52) of the gas path side (46a) such that the blade rub area (46a) is bare with regard to any ceramic coating (48).
