Title: The Innovations of John Edward Schilbe
Introduction
John Edward Schilbe is a notable inventor based in Whitehall, MI (US). He has made significant contributions to the field of engineering, particularly in the development of advanced materials and cleaning methods for gas turbine engines. With a total of 5 patents to his name, Schilbe's work has had a lasting impact on the industry.
Latest Patents
One of Schilbe's latest patents is a thermal barrier coating method and article. This innovation involves the formation of an outwardly grown diffusion aluminide bondcoat on a superalloy substrate. The bondcoat features higher concentrations of aluminum and platinum, along with lower concentrations of harmful impurities at its outermost region compared to the innermost region adjacent to the substrate. The bondcoat is pretreated before the deposition of a ceramic thermal insulative layer, which reduces grain boundary ridges on the outermost bondcoat surface without adversely affecting its properties. Additionally, the bondcoat is heat treated to thermally grow a stable alpha alumina layer prior to the deposition of the ceramic layer.
Another significant patent by Schilbe is a method for cleaning internal passages of airfoils in gas turbine engines. This chemical cleaning method involves immersing the airfoil in an inorganic hydroxide medium at superambient temperature and atmospheric pressure for a short duration. The process effectively removes accumulated oxides and dirt from the internal passage, utilizing a molten potassium hydroxide medium with immersion times not exceeding 10 minutes.
