Timepiece or jewelry component with black coating and stone
A recently filed patent (Publication Number: US20230288875A1) describes a component for timepieces or jewelry that includes a substrate partially coated with a black layer and decorated with at least one stone. The black layer can be made of carbon nanotubes or aluminum oxide. The substrate is devoid of the black layer on the surface of the bed where the stone is seated. The black layer can be flush with the table of the stone, and the stone can be set within the bed using a setting element. The component can include multiple alignments of stones with the black layer disposed between them.
The black layer can be a varnish containing carbon nanotubes, with the nanotubes having a random orientation within the varnish. Alternatively, the black layer can contain a high percentage of vertically aligned carbon nanotubes. The thickness of the black layer can range from 1 to 100 µm. In some embodiments, the black layer can be made of aluminum oxide, with a high percentage of aluminum content.
The patent also describes a method for manufacturing the component. The method involves providing the substrate, depositing the black layer, machining the bed, positioning and fixing the stone, and selectively removing the black layer from the surface of the bed. The manufacturing method can include various steps carried out in different orders, such as depositing the black layer before or after machining the bed, and selectively removing the black layer from the stone's surface using a mask.
The patent also covers an assembly comprising the described component and another component of a timepiece or jewelry, where the other component is at least partially coated with the black layer. The assembly can include a hand and a dial, with the hand mounted to move relative to the dial.
Overall, this patent describes a component and a manufacturing method that allow for the creation of visually appealing timepieces and jewelry pieces. The use of carbon nanotubes or aluminum oxide in the black layer provides a unique aesthetic, and the selective removal of the black layer ensures that the stone is showcased effectively.
