With a total of 2 patents, he has developed innovative methods that enhance the efficiency and effectiveness of repair processes in high-temperature applications.

Latest Patents

One of Hang Li's latest patents is a "Method for holding brazing material during a brazing operation." This method involves holding a sintering filler material during a brazing or sintering operation to repair damaged components. The technique allows for the component to be positioned in various orientations while ensuring the filler material is securely held in place. The method utilizes a wire mesh that is attached to the component at the damaged area, creating a gap that can accommodate the sintering filler material.

Another significant patent is the "Plural layer putty-powder/slurry application method for superalloy component crack vacuum furnace healing." This innovative process addresses the repair of heavy erosion and thermal fatigue cracks in high-temperature superalloy components, such as turbine vanes in gas turbine engines. The method eliminates the need for mechanical grinding, instead employing a finely granulated superalloy powder or low viscosity superalloy slurry to fill the cracks, followed by the application of a superalloy putty layer. The component is then sintered in a vacuum furnace to solidify the repairs.
