摘要： An assembly comprising a ceramic vane with a metal housing cast around the ends of the vane. The ceramic vane has dovetailed shaped grooves along its edges that extend from the vane's leading edge to its trailing edge. The housing is comprised of two spaced apart walls each having dovetailed protrusions for mating with the dovetail grooves in the vanes's edges. Upon the casting of the walls to the vane at least one surface of each dovetail groove comes in contact with at least one surface of the dovetail protrusion. A crushable coating is disposed between the vane's edges and the dovetail protrusions.
