Title: Innovations of Douglas J Peterman
Introduction
Douglas J Peterman is an accomplished inventor based in St. Louis, MO (US). He holds a total of 3 patents that showcase his expertise in materials science and engineering. His work primarily focuses on developing advanced materials with applications in radar technology and protective coatings.
Latest Patents
One of Peterman's latest patents is titled "Chemically modified radar absorbing materials and an associated fabrication method." This invention involves coated ferromagnetic particles that serve as radar absorbing material (RAM). The ferromagnetic particles, such as iron, carbonyl iron, cobalt, and nickel, are coated with a protective non-conducting material like silicon or aluminum oxide. The innovative coating process occurs in a rotating retort, allowing for effective deposition of the protective material. These coated particles are particularly suitable for use in corrosive environments.
Another significant patent is the "Method for forming in situ diffusion barrier while diffusing aluminum." This patent describes an improved protective coating system for metal substrates. The method enhances nickel-aluminide duplex coatings by incorporating boron during the nickel coating step. The retained boron migrates to the coating/substrate interface during the aluminization process, forming a diffusion barrier that inhibits the diffusion of impurities. This advancement enables the creation of thinner and more cost-effective coatings.
