摘要： Examples for refining the microstructure of metallic materials used for additive manufacturing are described herein. An example can involve generating a first layer of an integral object by heating a metallic material to a molten state such that the metallic material includes a solid-liquid interface. The example can further involve applying an electromagnetic field or vibrations to the metallic material of the first layer. In some instances, the electromagnetic fields or vibrations perturb the first layer of metallic material causing nucleation sites to form at the solid-liquid interface of the metallic material in the molten state. The example also includes generating a second layer coupled to the first layer of the integral object. Generating the second layer increases a number of nucleation sites at the solid-liquid interface of the metallic material in the molten state. Each nucleation site can grows a crystal at a spatially-random orientation.

摘要： A method for forming a hydrophobic coating on a substrate by a thermal spray deposition process is described. The method may comprise feeding a thermal spray apparatus with a coating precursor consisting of particles having an initial particle morphology, and heating the particles with the thermal spray apparatus to cause the particle to at least partially melt. The method may further comprise accelerating the particles towards the substrate, and forming the hydrophobic coating on the substrate by allowing the particles to impact the substrate in a partially melted state in which a fraction of the initial particle morphology of at least some of the particles is retained.

摘要： A method of forming a surface coating on a composite article may include applying a thermal spray to a tool surface of a tool in such a manner as to form a surface coating having a releasable bond with the tool surface. The method may further include applying composite material over the surface coating, curing the composite material to form a cured composite article, and removing the cured composite article from the tool in a manner that releases the surface coating from the tool surface and retains the surface coating with the cured composite article.
