Latest Patents
One of Stone's latest patents is titled "Crack Free Metallic Articles." This invention describes a containerless method of producing a crack-free metallic article of near-net shape. The process involves melting a filler material into a metallic substrate or seed under conditions that prevent cracking. A preferred embodiment utilizes a laser beam operated at a relatively low power density and a large beam diameter at the substrate surface for an extended duration, creating a molten pool with a low aspect ratio. This method is applied in a closed-loop, multi-axis material deposition system to achieve near-net shape.
Another significant patent is the "Method of Repairing Metallic Articles by Energy Beam Deposition." In this invention, a filler material is melted into a metallic substrate that has a defect, again under conditions chosen to prevent cracking. Similar to his previous patent, this method also employs a laser beam operated at low power density and a large diameter for an extended time to produce a molten pool with a low aspect ratio.
