Latest Patents

Wisner’s listed patents address advanced manufacturing and propulsion technologies.

- Diffusion Bonded Composite Material and Method Therefor. This invention describes forming a diffusion-bonded composite structure with internal voids or features. The method prepares and cleans the surfaces, seals exposed joints, and uses a hot isostatic process furnace. Low-pressure conditions bring the surfaces into close contact, while heat promotes diffusion bonding at their interfaces.

- Application of a Mixed Metal Oxide Catalyst to a Metallic Substrate. This invention presents a method for creating a durable, high-temperature catalyst system for decomposing propellants, particularly hydrogen peroxide, in propulsion systems. The process prepares a metallic substrate with a noble-metal intermediate layer, optionally incorporating a ceramic coating, then applies, dries, heat-treats, and activates a catalyst slurry.
