Abstract
An inlaid timepiece component (1) including a body (10) made of a metallic and/or ceramic material including at least one hollow (11) forming the impression of a decoration (12). The at least one hollow is completely filled with successive strata (13, 14, 15) formed by an agglomeration of particles (16) via a cold metallisation in order to form a timepiece component (1) inlaid with at least one decoration (12).
Claims12
An inlaid timepiece component including a body made of a metallic and/or ceramic material including a least one hollow forming the impression of a decoration, wherein said at least one hollow is completely filled with successive strata formed by an agglomeration of particles via a cold spray in order to form a timepiece component inlaid with at least one decoration,
- wherein each of the at least one decoration is covered by a metal layer coloured by means of an anodisation.
A method for manufacturing an inlaid timepiece component comprising the following steps:
- a) forming a body made of a metallic and/or ceramic material;
- b) engraving at least one hollow in a face of the body, each of at least one hollow forming an impression of a decoration;
- c) depositing a first stratum of a coating over a thickness of at least 10 μm over the entire face including said at least one hollow by a process of cold projection of a flow comprising a carrier gas and particles forming said coating;
- d) repeating step c) once or several times to deposit one or more additional strata of 20 μm each over the entire face including said at least one hollow covered with the first stratum in order to completely fill said at least one hollow and form an inlaid decoration;
- e) performing a polishing to remove all deposits of the strata off the surface of the body in order to leave them only in the at least one hollow;
- and
- f) covering each of the decorations with a metal layer coloured by means of an anodisation.
