内置式假肢部件
摘要：
本发明涉及一种由一陶瓷材料(9)制成的内置式假肢部件(1，2)，所述内置式假肢部件(1，2)的陶瓷材料(9)部分具有钛合金涂层。所述内置式假肢部件(1，2)的有涂层的一些表面部分用于与骨头(6，7)相连。根据本发明，陶瓷材料(9)与涂覆涂层的部分之间的分界面(8)的不平整度Ra为2.5μm至7μm。因此形成了涂层(10)与陶瓷材料(9)之间的稳固连接。本发明还涉及一种用于制造这种内置式假肢部件的方法。本发明最终涉及一种制造用于制备根据本发明的内置式假肢部件的陶瓷部件。为了使表面觉有预期的不平整度，在880℃至980℃之间预烧结陶瓷部件，接着使用溅射材料对陶瓷部件进行处理。
摘要（英）：

The invention relates to an endoprosthesis component (1, 2) formed from a ceramic material (9), the ceramic material (9) being partially coated with a titanium alloy. An uncoated portion of the surface of the endoprosthesis component is configured to cooperate as a sliding surface (3) with an additional endoprosthesis component (1, 2). A coated portion of the surface of the endoprosthesis component (1, 2) is configured to connect to a bone (6, 7). According to the invention, the portion of the ceramic material (9) forming a boundary surface (8) to the coating (10) has a roughness Ra between 2.5 [mu]m and 7 [mu]m, which results in a firm connection between the coating (10) and the ceramic material (9). The invention further relates to a method for producing such an endoprosthesis component. The invention finally relates to a method for producing a ceramic component that is able to serve as the basis for an endoprosthesis component according to the invention. In order to attain the desired roughness of the surface, the ceramic component is presintered at a temperature between 880 DEG C and 980 DEG C and subsequently treated with a blasting material.
