A method of forming the coated aluminum component is also described.
Abstract: The invention relates to an alloy consisting of at least three components A, B, C, which form at least a first matrix and a soft phase dispersed therein, with a first surface (5) and a second surface (9) lying opposite it, the proportions of components A, B, C in the alloy being different from one another in the regions of the first (5) and the second surface (8). At least one of the components forms a hard phase and at least one of the other components forms another matrix different from the first matrix, the first matrix being disposed at least in the region of the first surface (5) and the other matrix being disposed at least in the region of the second surface (8), whilst the hard phase is dispersed through both the first and the other matrix.
Abstract: A method of manufacturing a ceramic includes forming a film which includes a complex oxide material having an oxygen octahedral structure and a paraelectric material having a catalytic effect for the complex oxide material in a mixed state, and performing a heat treatment to the film, wherein the paraelectric material is one of a layered catalytic substance which includes Si in the constituent elements and a layered catalytic substance which includes Si and Ge in the constituent elements. The heat treatment includes sintering and post-annealing. At least the post-annealing is performed in a pressurized atmosphere including at least one of oxygen and ozone. A ceramic is a complex oxide having an oxygen octahedral structure, and has Si and Ge in the oxygen octahedral structure.
Abstract: Fine-grained (average grain size 1 nm to 1,000 nm) metallic coatings optionally containing solid particulates dispersed therein are disclosed. The fine-grained metallic materials are significantly harder and stronger than conventional coatings of the same chemical composition due to Hall-Petch strengthening and have low linear coefficients of thermal expansion (CTEs). The invention provides means for matching the CTE of the fine-grained metallic coating to the one of the substrate by adjusting the composition of the alloy and/or by varying the chemistry and volume fraction of particulates embedded in the coating. The fine-grained metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, automotive parts and components exposed to thermal cycling. The low CTEs and the ability to match the CTEs of the fine-grained metallic coatings with the CTEs of the substrate minimize dimensional changes during thermal cycling and prevent premature failure.

Abstract: A method for forming an elevated temperature durable coating on a surface of a substrate includes applying an aqueous slurry comprising lithium silicate, sodium silicate, potassium silicate, zirconia powder, a fibrous agent, and a magnetic powder to a surface of a substrate in one or more layers of substantially uniform thickness to form a coating. A substantially controlled humidity environment is maintained during application of the aqueous slurry and the coating is ambient dried for a period. A drying agent is applied to the coating and formation of a dry crust is prevented on the coating during ambient drying. After the period, the coating is heat cured.

Abstract: Thermal barrier coating (TBC) and a method of depositing a TBC having a modulated columnar microstructure that exhibits increased impact resistance. The TBC is deposited to have a columnar microstructure in which columns extend from a substrate surface. The columns having inner regions contacting the surface, outer regions near an outermost surface of the TBC, and interior regions therebetween. The inner regions of the columns are substantially normal to the substrate surface and at least one of the interior and outer regions of the columns are nonaligned with its respective inner regions, so that the columns of the columnar microstructure are continuous but modulated between the inner and outer regions to reduce tensile stresses within the columns resulting from particle impact.

Abstract: In a method for fabricating a nitride-based semiconductor laser which forms, by a selective deposition, a current narrowing structure and a structure confining a light in a horizontal direction in parallel to a substrate, when the nitride-based semiconductor is selectively deposited by a metal organic chemical vapor deposition, silicon generated by decomposition of the silicon oxide film used as the mask for the selective deposition is prevented from being deposited on a re-growth boundary. For this purpose, a silicon nitride film is used as the mask for the selective deposition, and when the nitride-based semiconductor is selectively deposited by the metal organic chemical vapor deposition, a V-group material of the nitride-based semiconductor, namely, a nitrogen material, for example, ammonia, is supplied so that the decomposition of the silicon nitride film used as the mask for the selective deposition, is prevented.
