Title: Innovations by John M McFadden
Introduction
John M McFadden is a notable inventor based in N. Muskegon, MI (US). He has made significant contributions to the field of materials science, particularly in the area of metal spraying techniques. With a total of 2 patents, his work has advanced the methods of forming composite articles and joining materials.
Latest Patents
One of McFadden's latest patents is titled "Method of forming a composite article by metal spraying." This innovative method involves spraying molten metal onto the surface of a preheated solid metal member in a controlled atmosphere at low pressure. The molten metal rapidly solidifies, adhering to the surface and forming a composite preform. This preform is then cooled at a controlled rate to minimize residual stresses and is hot pressed to eliminate voids, ensuring a strong metallurgical bond.
Another significant patent is the "Method for joining materials by metal spraying." This method focuses on joining metal materials by spraying molten metal into a cavity between the articles to be joined. Prior to the deposition of the metal, the surfaces are cleaned and preheated. After the metal is deposited, the joined articles are cooled at a rate that prevents thermal damage, and the deposited metal is consolidated through hot pressing.
