With a total of 3 patents to his name, Leggett's work has garnered attention for its innovative approaches and practical applications.
Latest Patents
Leggett's latest patents include an article and method of manufacturing the same. This patent discloses a method that involves providing an article with a substrate and a coating that is at least partially disposed on the substrate. The coating comprises an outer surface that includes platinum and chromium. The method further details the application of cold work to the outer surface of the coating, resulting in a cold-worked layer that extends from the outer surface to a specified cold work depth. This cold-worked layer contains approximately 45% cold work, with a depth ranging from about 30 microns to about 150 microns.
Another significant patent is for an erosion-resistant coating. This innovation involves a platinum plus chromium coating applied to the roots and firtrees of turbine blades. The inclusion of chromium creates a single-phase outer zone that minimizes diffusion paths for sulfur, which can preferentially diffuse down phase boundaries. This enables a chromium-rich outer oxide scale to form on top of the coating, enhancing the durability and performance of turbine blades.
