Aug 15, 2017 Fused and crushed powder is powder formed from a fused solid mass which is then crushed to the appropriate size for spraying. Fusion and crushing techniques produce powders that are consistent in size, shape, color, chemistry and toughness. The powder is used in thermal spray applications of thermal barrier coatings (TBCs) and high-temperature

A method is disclosed for removing essentially all of the water from fine metal powders. The method involves contacting the powder particles which have water on at least some of the particle surfaces with a solution of a fluorocarbon solvent and a hydrophobic surfactant, with the amount of the surfactant being sufficient to form at least a monolayer adsorbed onto the particle surfaces, and
