Embodiments of a system, method and apparatus for a gear are disclosed. For example, a metallic gear hub can include an axis of rotation and metallic gear teeth. The metallic gear teeth can be smaller than a final gear teeth size of the gear. The metallic gear teeth can be co-planar with the axis. In addition, the metallic gear teeth can be non-orthogonal to the axis. A polymer layer can be located on the metallic gear teeth to form polymer gear teeth on the metallic gear teeth. The polymer gear teeth can form the final gear teeth size of the gear.

The present invention relates to a superhydrophobic coating film in which an aerogel nanocomposite is coated on a substrate to maximize water-repellent properties and durability, and a producing method thereof. According to one embodiment of the present invention, the method of producing the superhydrophobic coating film using the aerogel nanocomposite includes (a) preparing a hydrophobic aerogel, (b) preparing a water-repellent solution by dissolving the hydrophobic aerogel in a hydrophobic inorganic nano-sol, (c) applying the water-repellent solution on at least one surface of a substrate, and (d) drying the substrate.

A fan blade and a fabricating method thereof are provided. The fan blade includes a rough coating layer on a surface thereof. The rough coating layer includes a plurality of recessed regions. A maximum depth of recess of the recessed regions is between 50 μm to 130 μm.

A viewing lens and method for treating lenses to minimize glare and reflections for birds with tetra-chromatic vision. The anti-reflection lens is treated to with a coating on the surface. The coating is configured to enable the lens surface to be less perceptible to a bird with tetra-chromatic vision by reducing reflections therefrom. The lens treatment includes applying an anti-reflective coating in multiple coats. The coats comprise an adhesion composition, a low index composition (such as SiO.sub.2), a high index composition (such as ZrO.sub.2), and a superhydrophobic composition that are applied in subsequent layers of varying nanometer thicknesses. The treated lens exhibits minimal reflection properties in the visible range of the electromagnetic spectrum and almost no reflection in the UV-A range. This creates a lens surface that is difficult for birds with tetra-chromatic vision to see a reflection therefrom.

A method of forming a digital print on a surface by applying powder of dry ink including colourants on the surface, bonding a part of the dry ink powder to the surface by a digital heating print head such that the digital print is formed by the bonded dry ink colourants and removing non-bonded dry ink from the surface.

Disclosed is a method for treating a grained material. A nonlimiting example of the method includes the operations of providing a workpiece having grains, exasperating a surface of the workpiece to open the grains, applying at least one coat of a base paint to the exasperated surface, applying at least one layer of clear coat on the base paint, applying at least one of a glaze and a paint on the clear coat, and surface treating to reveal grains of the workpiece. Disclosed also are items of furniture and sheet materials treated by the aforementioned process.

A coated metal alloy substrate with at least one chamfered edge, a process for producing a coating a metal alloy substrate, and an electronic device having a housing comprising a coated metal alloy substrate are described. The coated metal alloy substrate with at least one chamfered edge comprises a hydrophobic anti-fingerprint layer deposited on the metal alloy substrate, a passivation layer deposited on the at least one chamfered edge, and a water based paint layer deposited on the passivation layer.

The present disclosure relates to a treating method of a metal surface, and a coating method thereof using the same. A treating method of a metal surface may include grinding solid carbon dioxide and then spraying the ground solid carbon dioxide onto a metal surface. After spraying the ground solid carbon dioxide, irradiating short-wavelength ultraviolet rays on the metal surface, thereby removing foreign substances attached to the metal surface, reforming the metal surface into a hydrophilic surface and improving wettability of a coating material.

The disclosure relates to a method for fabricating a speckle for high temperature deformation measurement of a shaped refractory material. A technical solution includes mixing a hercynite micropowder and a liquid mixing agent in a mass ratio of (3-6):1, and ultrasonically treating to obtain a speckle mixture; polishing a surface of a shaped refractory material to be measured, removing impurities, and spraying the speckle mixture on the surface of the shaped refractory material to be measured with a pneumatic airbrush in a time hood to obtain an uncured speckle; heating the uncured speckle to 60-80° C., keeping for 1-3 h, then heating to 100-120° C., and keeping for 1-3 h to obtain a speckle for high temperature deformation measurement of a shaped refractory material. The fabricated product is suitable for high temperature deformation measurement of a shaped refractory material at 1,600° C.
