Ceramised component with decoration and its manufacturing method

A method for manufacturing a decorative piece comprising the following steps:

• preparing a substrate (1) made of a zirconium-based amorphous metallic alloy, said substrate (1) comprising a surface (1a) defining a first part with a positive and/or negative relief (2) relative to the plane of the surface (1a) and a second part extending in the plane of the surface (1a), the first part or the second part being designed to form a decoration (4),
• depositing a ceramic layer (3) on at least a portion of the first part and of the second part or converting the substrate (1) into a ceramic layer (3) on at least a portion of the first part and of the second part,
• removing the surplus from the ceramic layer (3) on said portion to obtain the first part formed from the substrate (1) and the second part formed from the ceramic layer (3) deposited on the substrate (1) or conversely to obtain the first part formed from said ceramic layer (3) deposited on the substrate (1) and the second part formed from said substrate (1), with the first part or the second part forming the decoration (4).
