Title: George J Durmann: Innovator in Flame Spray Technology
Introduction
George J Durmann is a notable inventor based in Farmingdale, NY (US). He has made significant contributions to the field of materials science, particularly in the development of flame spray technologies. With a total of 3 patents to his name, Durmann's work has had a lasting impact on various industrial applications.
Latest Patents
One of Durmann's latest patents is for a flame spray powder. This innovative powder is a free-flowing self-bondable flame spray powder derived from an atomized alloy powder. The particles are characterized by aspherical shapes and have an average particle size within the range of about plus 400 mesh to minus 100 mesh. The aspherically shaped powder is further characterized by a specific surface area of about 180 cm²/gr and higher. It consists essentially of a solvent metal alloy selected from iron-group base alloys, including nickel-base, iron-base, and cobalt-base alloys, containing by weight about 5% to 35% chromium. The solvent metal alloy has a negative free energy of oxidation ranging up to about 80,000 calories per gram atom of oxygen at 25°C and contains about 5% to 15% by weight of a highly oxidizable solute metal.
Another significant patent is for an apparatus for spraying heat responsive materials. This apparatus features a serpentine path that allows a flow of compressed air or an inert gas to traverse the inside surface of the housing, maintaining the outside surface in a relatively cool condition. The compressed air or inert gas continues to flow along its serpentine path, gradually heating, and is then centrally discharged together with the material to be sprayed. Baffle means are provided surrounding the nozzle to prevent 'powder balling' or 'spitting' of the resin as it is discharged.
