With a total of nine patents to his name, Douglas has made significant advancements that enhance the efficiency and effectiveness of manufacturing processes.
Latest Patents
Among his latest patents, Douglas has developed a method of manufacturing an article by superplastic forming and diffusion bonding. This innovative process involves placing a stack of titanium sheets on a worktable within a vacuum chamber. One of the mating surfaces of each pair has a stop-off material applied in a specific pattern to prevent diffusion bonding. The vacuum chamber is evacuated, and heaters are used to evaporate volatile binders from the stop-off. Once the binder is removed, the worktable is moved relative to an electron beam to weld the edges of the sheets together, forming a sealed assembly. This method prevents oxidation of the titanium during the binder removal process. The sealed assembly is then heated and pressurized to diffusion bond the sheets together, followed by superplastic forming to create an article of a predetermined shape.
