Abstract: A composite composition that includes an MCrAlX alloy and a nano-oxide ceramic is disclosed. In the formula, M includes nickel, cobalt, iron, or a combination thereof, and X includes yttrium, hafnium, or a combination thereof, from about 0.001 percent to about 2 percent by weight of the alloy. The amount of the nano-oxide ceramic is greater than about 40 percent, by volume of the composition. A protective covering that includes the composite composition is also disclosed. The protective covering can be attached to a tip portion of a blade with a braze material. A method for joining a protective covering to a tip portion of a blade, and a method for repair of a blade, are also provided.

Abstract: A coated article is disclosed including a substrate, a bond coating, and a thermally insulating top coating. The substrate includes a substrate surface and a substrate material at the substrate surface. The bond coating is disposed on and contacts the substrate surface, and includes the substrate material and a bond coating surface distal from the substrate surface. The bond coating surface includes a greater surface roughness than the substrate surface. The thermally insulating top coating is disposed on and contacts the bond coating surface. A method for forming the coated article includes applying the bond coating to the substrate surface, and applying the thermally insulating top coating to the bond coating surface.

Abstract: A method of providing an oxidation resistant coating is disclosed. The method includes providing a substrate having a first surface and cooling holes. A portable coating device includes electro-spark deposition (ESD) equipment and an ESD torch connected with the ESD equipment. The ESD torch has an inert gas source and a rotary electrode conductive material. The rotary electrode is positioned within the ESD torch, and is shielded by an inert gas. The rotary electrode applies a compositionally controlled protective coating to the first surface of the substrate. Then the rotary electrode is inserted into the cooling hole and generates an electrospark between rotary ESD electrode and the substrate to form a rounded edge and deposit a coating of electrode material alloy at a cooling hole edge.
