Title: Charalabos Doumanidis: Innovator in Composite Coatings and Prototyping Technologies
Introduction
Charalabos Doumanidis is a notable inventor based in Vienna, VA (US), recognized for his contributions to the fields of composite coatings and advanced prototyping technologies. With a total of 2 patents, his work focuses on enhancing material properties and manufacturing processes.
Latest Patents
Doumanidis's latest patents include innovative methods for forming composite coatings on substrates. One patent details a precursor-based method for producing metal-matrix composite (MMC) coatings on steel and aluminum substrates. This process improves wear, corrosion, and oxidation resistance. The method involves depositing wire and surface precursors on the substrate through controlled thermal processing using plasma-arc, laser, and high-density infrared radiation. The temperature distribution during coating formation is managed by a real-time adaptive control method. Additionally, wire precursors produced by continuous pressure infiltration of SiC or mullite fiber with aluminum are utilized. Steel substrates are double-layer plated with binary metals, including nickel and aluminum, which are thermal-processed to in-situ produce compounds such as nickel aluminide coatings.
Another significant patent involves a method and apparatus for producing three-dimensional parts from multiple planar layers using ultrasonic welding. In this process, a sheet of planar material is placed on a partial part and ultrasonically welded, with the first sheet positioned on a base. The sheet is then cut to the shape of the partial part. This method allows for the introduction of components sensitive to manufacturing temperatures, such as thermal actuators and optical components, between layers of material.
