ABSTRACT:
Rhenium nanoparticle mixtures and methods for making the same are provided. The rhenium nanoparticle mixture can be painted onto a surface to be coated and dried at low temperatures to form a gas-tight elemental rhenium coating. Moreover, the rhenium nanoparticle mixture can be used to join rhenium components and temperatures far lower than traditional welding techniques would require. The low temperature formation of rhenium coatings allows rhenium coatings to be provided on surfaces that would otherwise be uncoatable, whether because of their inability to withstand high temperatures (e.g., carbon/carbon composites, graphite, etc.), or because the high aspect ratio of the surface would prevent other coating methods from being effective (e.g., the inner surfaces of tubes and nozzles).
