Latest Patents

Ridder's latest patents focus on a thermal barrier coating ceramic structure. This multilayered ceramic topcoat is designed 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 the first ceramic layer. The substrate is then 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 innovative approach enables uniform coating of complex contoured surfaces, such as turbine blade airfoils, by rotating the blade during the coating deposition.
