发明名称 Process for manufacturing a ceramic element for a watch case and element obtained by this process
摘要 According to this process for manufacturing a ceramic element intended to be fitted onto a watch case, the visible surface of which has features, a soluble layer (2) is selectively deposited on said visible surface, the thickness of said soluble layer being at least equal to the height of said features, a first tie layer (3) of the Ti, Ta, Cr or Th type is vacuum-deposited by magnetron sputtering with a thickness of at least 100 nm by physical vapor deposition (PVD) on said surface thus selectively coated, followed, without venting atmosphere, by PVD deposition of said second layer (4) made of Au, Pt, Ag, Ni, Pd, TiN, CrN, ZrN or alloys thereof with a thickness of at least 100 nm, and then said soluble layer (2) is dissolved.
