Abstract: A gas turbine engine includes a rotor that has a rim, blades extending radially outwards from the rim, a hub extending radially inwards from the rim, an arm extending axially from the rim, the arm having a radially outer surface, and a coating disposed on the radially outer surface. The coating is zirconia-toughened alumina in which the alumina is a matrix with grains of the zirconia dispersed there through. The grains of zirconia are predominantly a tetragonal crystal structure.

Abstract: A method of manufacturing a net shaped seal comprises depositing a first layer of fine powder comprising an abradable feed stock material on a substrate. The method includes guiding a heat source over the fine powder material layer; fusing together the fine powder material; depositing a second layer of fine powder material over the first layer; fusing the second layer of fine powder material with a second pass of the heat source at predetermined locations; and repeating the depositing step and fusing step to form subsequent layers to form an abradable seal on the substrate.
