An abradable ceramic seal coating on at least one of a pair of members having relative rotational movement, the coating being formed of stabilized zirconia which is codeposited with a thermally decomposable organic powder, the codeposited layer being heated to decompose the organic filler and produc

대표청구항 ▼

A thermal barrier-fluid seal abradable coating for use in machinery having cooperating members capable of relative rotational movement and operating in a high temperature environment, at least one of said members being the coating substrate, the coating on said substrate comprising a bond layer consisting essentially of a NiCrAlY alloy covering a wear surface of said substrate, a thermal barrier layer on said bond layer consisting essentially of zirconia and a zirconia stabilizing oxide selected from the group consisting of Y2O3, MgO and CaO, and an abradable layer on said thermal barrier layer consisting essentially of porous stabilized zirconia, said porous zirconia resulting from the thermal decomposition of an organic filler material codeposited with the stabilized zirconia on said barrier layer, said abradable layer having from about 20 to about 33% voids. In a turbomachine having two members capable of relative rotational movement, at least one of the members having a thermal barrier coating of the stabilized zirconia type subject to rubbing contact, and a bond layer of a NiCrAlY alloy between said thermal barrier coating and said member, the improvement comprising a porous abradable layer on said coating consisting essentially of zirconia containing an oxide from the group consisting of Y2O3, MgO and CaO, said porous abradable layer resulting from the thermal decomposition of a polyester particulate filler codeposited with said zirconia and said oxide in an amount of from about 20 to about 33% by volume to achieve the desired layer density and abradability.
