Abstract
In one aspect, a rotor shroud for a rotary machine includes a disk portion extending along and oriented about a central axis of the rotary machine, a transition portion extending from the disk portion, and a flared portion extending axially from the transition portion. The disk portion, the transition portion, and the flared portion include a plastic substrate and metal plating disposed on at least apportion of an outer surface of the plastic substrate. The plastic substrate has a matrix material and fibers embedded in the matrix material. The fibers have a first coefficient of thermal expansion. The metal plating has a second coefficient of thermal expansion. The fibers are selected such that a bulk coefficient of thermal expansion of the plastic substrate at the outer surface of the plastic substrate substantially matches the second coefficient of thermal expansion of the metal plating.
