Latest Patents
One of his latest patents is titled "Method of heat treating a cobalt-base alloy." This innovative method describes an improved technique for repairing Co-base superalloy gas turbine engine components. It involves applying a mixture of base alloy powder and a melting point depressant to the surface of the component and heating it at 2250-2300°F. This process allows for the isothermal diffusion of the melting point depressant into the base alloy, resulting in components with significantly enhanced high-temperature creep properties compared to previous methods.
Another significant patent is the "Method of rejuvenating cobalt-base superalloy articles." This method focuses on restoring the mechanical properties of carbide-containing Co-based superalloy gas turbine components that have been subjected to high temperatures and pressures over extended periods. The rejuvenation process includes solution heat treating at 2250-2300°F for one to twelve hours to dissolve complex carbides, followed by aging at approximately 1965-1975°F for two to twenty-four hours. The rejuvenated components demonstrate excellent high-temperature creep properties.
