Description
Patent Number: 202141035836, Applicant: Gowtham Sanjai.
This invention discloses a method to produce free flowing plasma sprayable powders comprised of nano a-Alumina grains, suitable for injection into the high temperature plasma stream of an atmospheric plasma spray system. The plasma sprayable powder particles will be in the range of 30-90 microns, but the grains within the powder particles will only be about 50 nanometers. This micron sized powder, when flowing through the high temperature plasma will dissociate to release the nano grains, resulting in 12 to 15 microns thick coatings, deposited on the substrate per individual pass.
