A method for manufacturing an engine component, the method comprising:

• providing a preform engine component comprising a substrate, the substrate including a substrate surface and a plurality of apertures, and each of the plurality of apertures projecting partially into the substrate from the substrate surface, wherein the substrate comprises yttria-stabilized zirconia;
• and
• forming a coating on the substrate, the coating including a base and a plurality of projections, the base covering the substrate surface, each of the plurality of projections projecting out from the base into and filling a respective one of the plurality of apertures, and the forming of the coating comprising electroless plating a coating material onto the substrate over the substrate surface and within the plurality of apertures.

A method for manufacturing an aircraft engine component, the method comprising:

• providing a substrate that comprises an electrically non-conductive material, the substrate including a substrate surface and a plurality of apertures, and each of the plurality of apertures projecting partially vertically into the substrate from the substrate surface;
• and
• electroless plating a coating material onto the substrate to form a plated structure, the plated structure including a base and a plurality of projections, the base covering the substrate surface, each of the plurality of projections projecting vertically out from the base into and filling a respective one of the plurality of apertures, and the plurality of projections comprising a first projection, wherein the coating material comprises a nickel nano-crystalline coating.
