MANUFACTURE OF MULTICOLOURED CERAMIC COMPONENT
SOLUTION: A method for manufacturing a ceramic timepiece component includes the steps of: manufacturing an intermediate component (E1) in the form of a green body based on ceria-zirconia; totally or partially debinding (E2) the intermediate component to obtain a debound intermediate component; partially impregnating (E3) the debound intermediate component with at least one solution comprising at least one metal salt, on one portion only of its surface, to obtain an impregnated debound intermediate component; sintering and thermally treating (E4) the impregnated debound intermediate component by performing at least one heat treatment under a reducing atmosphere (E42; E41').SELECTED DRAWING: Figure 1
【解決手段】セリア－ジルコニア基のグリーン体の形態の、中間部品を製造する（Ｅ１）、脱バインダ中間部品を得るために、中間部品を全部または一部脱バインダする（Ｅ２）、含浸脱バインダ中間部品を得るために、少なくとも１つの金属塩を含む、少なくとも１つの溶液により、脱バインダ中間部品を、その表面の一部のみに、局所的に含浸する（Ｅ３）、含浸脱バインダ中間部品を、還元雰囲気下の少なくとも１つの熱処理のステップ（Ｅ４２；Ｅ４１’）により、焼結及び熱処理する（Ｅ４）、ステップを含む、セラミック時計部品の製造方法。【選択図】図１
