Latest Patents

One of his latest patents is titled "Process of preparing a ferritic alloy with a wear-resistive alumina scale." This invention describes a method for creating a ferritic alloy that features a wear-resistant oxide scale. The process involves pressing a ferritic alloy powder containing aluminum into a compact, sintering it in a non-oxidizing atmosphere, and then heat-treating it in an oxidizing gas atmosphere. This results in the formation of an alumina scale that enhances surface hardness and wear resistance. The unique porous nature of the sintered product allows for deep penetration of the oxidizing gas, facilitating the formation of the alumina scale, which can be controlled in thickness based on the product's density.

Another significant patent is the "Method and apparatus for forming a metal sheet having a concave-convex profile." This invention utilizes chemical vapor deposition to create a metallic sheet with a concave-convex profile. The method involves using a die with a profiled surface and a transparent mask to deposit a metallic layer onto the surface. The apparatus includes a reaction chamber where the die and mask are mounted, allowing for efficient production of the metallic sheet.
