Latest Patents

Ticheler's latest patents focus on a multilayered ceramic topcoat for thermal barrier coating systems. This innovative design is particularly useful for high-temperature corrosive applications, such as hot section components in gas turbine engines. The ceramic topcoat consists of at least two layers, each featuring generally columnar grain microstructures with different grain orientation directions. A preferred method for producing this multilayered ceramic topcoat involves positioning a superalloy substrate at a first angled orientation relative to a ceramic vapor cloud in an electron beam physical vapor deposition apparatus. This process allows for the growth of a first ceramic layer, after which the substrate is reoriented to a second, different angled orientation to grow a second ceramic layer. The resulting ceramic layers exhibit columnar microstructures with grain orientation directions that correspond to the substrate orientations. This method is particularly effective for uniformly coating complex contoured surfaces, such as turbine blade airfoils.
