METHOD FOR MANUFACTURING A COMPOSITE COMPONENT OF A TIMEPIECE OR OF A JEWELRY PART, AND COMPOSITE COMPONENT OBTAINABLE BY SUCH METHOD
The invention relates to a method for manufacturing a composite component of a timepiece or of a jewelry part, the composite component comprising a porous ceramic part and a metallic material filling the pores of said ceramic part, said method comprising the steps of: - providing a porous ceramic preform of the component, - providing a metallic material, - heating the metallic material to a temperature higher than the melting point of the metallic material, - filling the pores of the ceramic preform with the molten metallic material, - cooling the metallic material and the ceramic preform to obtain a solidified metallic material in the pores of the ceramic preform, and - applying finishing treatments to obtain the composite component, wherein said porous ceramic preform consists essentially of a material selected from the group consisting of Si 3 N 4 , SiO 2 and mixtures thereof, and said metallic material is selected from the group consisting of gold, platinum, palladium metals and alloys of these metals. The invention relates also to a composite component of a timepiece or of a jewelry part comprising a porous ceramic part and a metallic material filling the pores of said ceramic part, wherein said porous ceramic part consists essentially of a material selected from the group consisting of Si 3 N 4 , SiO 2 and mixtures thereof, and said metallic material which is selected from the group consisting of gold, platinum, palladium metals and alloys of these metals.
