摘要： A method of forming a thermal barrier coating onto a surface of a ferrous alloy or nickel alloy component part involves depositing a layer of hollow microspheres to a surface of the component part or to a previously deposited layer of hollow microspheres through heating and cooling of a metallic precursor setting layer composed of copper, a copper alloy, or a nickel alloy. Once deposited in place, the layer(s) of hollow microspheres are heated to sinter the hollow microspheres to each other and to the surface of the ferrous alloy or nickel alloy component part to form an insulating layer.

摘要： A thermal barrier coated metallic article includes a platinum-group metal enriched outer layer on the article. The surface of the outer layer has a microstructure including a plurality of projections extending away from the metallic article. A thin adherent layer of oxide is formed on the outer layer of the metallic article. A ceramic coating is provided on the oxide layer on the surface on and around the projections. The ceramic coating includes a plurality of columnar ceramic grains which extend through the full thickness of the ceramic coating. The grains are arranged in clusters separated by gaps. The grains deposited around the projections are generally blocked. The projections reduce the stress in the ceramic coating near the interface with the adherent layer of oxide and also reduce the stress in the adherent layer of oxide and hence increase the working life of the thermal barrier coating system.
