Abstract:
A coated article is described. The coated article includes a stainless steel substrate, a bonding layer formed on the substrate, and a hard layer formed on the bonding layer. The bonding layer is a nickel-chromium alloy layer. The hard layer is a nickel-chromium-boron-nitrogen layer. The mass percentage of nitrogen within the hard layer is gradually increased from the area near the bonding layer to the area away from the bonding layer. A method for making the coated article is also described.
Abstract:
A method for making a magnesium-based composite material includes mixing nanoscale reinforcements with a melted magnesium-based material to obtain a pre-mixture. The pre-mixture is agitated by an ultrasonic process to obtain a mixture. The mixture is sprayed to a substrate.
Abstract:
A coated article is provided. A coated article includes a substrate having a color layer and a ceramic layer formed thereon, and in that order. The color layer substantially comprises a material elected from the group consisting of aluminum, aluminum alloy, zinc, and zinc alloy. The ceramic layer substantially consists of substance M, elemental O, and elemental N, wherein M is elemental Al or elemental Zn.
Abstract:
A coated article is described. The coated article includes a substrate and an alloy layer formed on the substrate. The alloy layer contains iron, silicon, boron, and carbon. The iron within the alloy layer has an atomic percentage of about 60%-95%, the silicon has an atomic percentage of about 1%-20%, the boron has an atomic percentage of about 1%-10%, and the carbon has an atomic percentage of about 1%-10%. A method for making the coated article is also described.
Abstract:
A method for making a coated article includes the steps of: providing a substrate; forming a copper-iron target by a hot isostatic pressing process using copper powder and iron powder; forming a copper-iron alloy layer on the substrate by vacuum sputtering using the copper-iron target. A coated article is also described.
Abstract:
A device housing is provided. The device housing includes a substrate, a barrier layer formed on the substrate, an illuminating layer formed on the barrier layer, and a protective layer formed on the illuminating layer. The barrier layer is made of titanium. The illuminating layer is made of rare-earth aluminates. The protective layer is made of silica dioxide. A method for making the device housing is also described there.
Abstract:
A coated article is described. The coated article includes a substrate, a plurality of titanium dioxide layers and a plurality of copper layers formed on the substrate. Each titanium dioxide layer interleaves with one copper layer. One of the titanium dioxide layers forms an outermost layer of the coated article. A method for making the coated article is also described.
Abstract:
A coated article is described. The coated article includes a substrate, a bonding layer formed on the substrate, a plurality of nickel-chromium-nitrogen layers and a plurality of copper-cerium alloy layers formed on the bonding layer. The bonding layer is a nickel-chromium layer. Each nickel-chromium-nitrogen layer interleaves with one copper-cerium alloy layer. One of the nickel-chromium-nitrogen layers is directly formed on the bonding layer. A method for making the coated article is also described.
Abstract:
A coated article is described. The coated article includes a substrate, a bonding layer formed on the substrate, a plurality of nickel-chromium-nitrogen layers and a plurality of silver-cerium alloy layers formed on the bonding layer. The bonding layer is a nickel-chromium layer. Each nickel-chromium-nitrogen layer interleaves with one silver-cerium alloy layer. One of the nickel-chromium-nitrogen layers is directly formed on the bonding layer. A method for making the coated article is also described.
Abstract:
A coated article includes a substrate including a porous surface and an anodic oxidation film. The porous surface defines a plurality of nanopores. The anodic oxidation film is formed on the substrate covering the porous surface by anodic oxidation process. The anodic oxidation film has a plurality of bonding protrusions, and each bonding protrusion is retained in one of the nanopores to improve a binding force between the substrate and the anodic oxidation film.
