CERAMIC ELEMENT INLAID WITH AT LEAST ONE CERAMIC DECORATION |
| 摘要 |
The invention relates to a method of manufacturing an inlaid ceramic element for a timepiece comprising the following steps:
a) forming a ceramic body;b) etching at least one recess in one face of the ceramic body, each at least one recess forming the pattern cavity for a decoration;c) changing the surface state of the bottom of said at least one recess in order to increase the contact surface thereof;d) depositing, by thermal spraying, a second ceramic material above said at least one recess in order to totally fill said at least one recess;e) flattening said second ceramic material so that said second ceramic material remains only in the hollow of said at least one recess. |
