摘要:
The invention concerns a multilayer coating with high absorption of solar energy and with low thermal emissivity that comprises a first layer of molybdenum; a second layer essentially made up of TiO 2 and niobium metal; and a third layer of SiO 2 . The invention moreover concerns a relative cermet composite essentially made up of TiO 2 and niobium metal in which the concentration of niobium in the TiO 2 corresponds to 27 - 34 at.%, preferably to 29.6 - 32.0 at.%, more preferably to 30.2 - 31.4 at.%, even more preferably to around 30.8 at.%. Furthermore, processes for producing the coating and the cermet composite, laminar or tubular materials coated with the coating and a use of the cermet composite are proposed.

摘要:
A substrate treated with color development, according to the present invention is provided with areas on the surface having different temperatures to induce an average thickness difference in the coating, when a coating is formed on a matrix surface containing magnesium, thereby maintaining a metal texture unique to the substrate while enabling the development of several colors on the substrate surface with a single color development treatment, and thus can be useful in areas using magnesium materials, such as external materials for construction, vehicle interiors, and especially in the electrical and electronic parts material fields such as in mobile phone case parts.

摘要:
A composition and method of kinetically depositing the composition to form a coating onto an exterior surface of a zirconium alloy cladding of a light water nuclear reactor which at least partially adheres to the exterior surface. The coating composition includes a first component and a second component. The first component is selected from the group consisting of zirconium, zirconium oxide and mixtures thereof. The second component is selected from the group consisting of Zr2AlC ceramic, Ti2AlC ceramic, Ti3AlC2 ceramic, Al2O3, aluminum, zirconium silicide, amorphous and semi-amorphous alloyed stainless steel, and mixtures of Zr2AlC ceramic, Ti2AlC ceramic and Ti3AlC2 ceramic. The coating has a gradient emanating from the exterior surface of the cladding toward an exposed outer surface of the coating such that percent by weight of the first component decreases and the second component increases from the exterior surface of the cladding toward the exposed outer surface of the coating.

摘要:
To produce a trivalent chromium based coating on an object, a layer of nickel phosphorus alloy is deposited on the object, an intermediate layer of another metal or metal alloy or ceramic is deposited on the NiP layer, and a chromium layer is deposited from a trivalent chromium bath on the intermediate layer. The coated object is subjected to one or more heat treatments to harden the coating and to produce multiphase layers including at least one layer containing crystalline Ni and crystalline Ni3P and at least one layer containing crystalline Cr. The intermediate layer can consist of copper, molybdenum, a metal alloy or a non- metallic solid, such as an oxide, nitride or carbide of a metal.
摘要:
The present invention relates to a color-treated base material and a base material color treatment method therefor. The base material is capable of improving the homogeneity and corrosion resistance of the surface of the base material and realizing a uniform color in a short period of time. Accordingly, the color-treated base material can be usefully used in the fields of building exterior materials, automobile interiors, and particularly electrical and electronic component materials, such as mobile phone case components, in which a magnesium material is used.
