Abstract
A method for fabricating a composite timepiece or jewellery component: a base is made in a substrate with an apparent surface remaining visible; each visible apparent surface is mirror polished; each polished apparent surface is coated with a first transparent or coloured semi-transparent layer of a first material in a dry process, or PVD or CVD or ALD process, or lacquering or zapon varnish process; a decorative element is affixed and bonded to an external surface of the first layer; the first layer and each decorative element is coated with a second layer of a transparent treatment material in a dry process, or PVD or CVD or ALD process, or lacquering or zapon varnish process.
Claims17
A method for fabricating a composite timepiece or jewellery component comprising at least one decoration affixed to a substrate which has at least one apparent surface intended to remain visible, wherein the following operations are performed in this order:
- in an initial operation, making a base in the substrate which has at least one apparent surface intended to remain visible;
- in a first polishing operation, mirror polishing each said apparent surface intended to be seen by the user;
- performing a first coating operation wherein each said polished apparent surface comprised in said base is coated with a deposition of a first transparent or coloured semi-transparent layer of a first material in a dry process, or PVD or CVD or ALD process, or lacquering or zapon varnish process;
- performing an intermediate machining operation wherein geometric alignment is performed on said first layer and/or a polishing operation is performed on a first external surface of said first layer;
- performing a first transfer operation of affixing and bonding at least one decorative element on the first external surface comprised in said first layer;
- performing a second coating operation wherein said first layer and each said decorative element carried by said first layer is coated with a deposition of a second layer of a transparent treatment material in a dry process, or PVD or CVD or ALD process, or lacquering or zapon varnish process,
- wherein, during said initial operation, said at least one apparent surface is made with a particular curved shape, and wherein, prior to performing said first transfer operation, said first layer is made, and the first external surface of said first layer corresponds to said particular curved shape, said at least one said decorative element being affixed to the first external surface of said first laver with an adhesive fastening during said first transfer operation, and
- wherein, during said initial operation, said base is made with marker elements, and wherein said first layer is made with marker elements complementary to the marker elements of said base for the exact relative positioning thereof prior to the bonding of each said decorative element carried by said first layer.

- performing an intermediate machining operation wherein geometric alignment is performed on said first layer and/or a polishing operation is performed on a first external surface of said first layer;
- performing a first transfer operation of affixing and bonding at least one decorative element on the first external surface comprised in said first layer;
- performing a second coating operation wherein said first layer and each said decorative element carried by said first layer is coated with a deposition of a second layer of a transparent treatment material in a dry process, or PVD or CVD or ALD process, or lacquering or zapon varnish process,
- during said intermediate machining operation, the geometric alignment is performed such that at least one portion of said first external surface comprised in said first layer has a particular curved shape, and wherein, during the performing said first transfer operation, said at least one said decorative element is affixed to said at least one portion of said first external surface comprised in said first layer with an adhesive fastening, and
- wherein, during said initial operation, said base is made with marker elements, and wherein said first layer is made with marker elements complementary to the marker elements of said base for the exact relative positioning thereof prior to the bonding of each said decorative element carried by said first layer.
