The invention relates to an endoprosthesis component which is formed from a ceramic material and in which the ceramic material is partially coated with a titanium alloy. An uncoated surface portion of the endoprosthesis component is designed to interact as slide surface with another endoprosthesis component. A coated surface portion of the endoprosthesis component is designed to establish a connection to a bone. According to the invention, the part of the ceramic material forming an interface to the coating has a roughness Raof between 2.5μm and 7μm. This creates a firm connection between the coating and the ceramic material. The invention further relates to a method for producing such an endoprosthesis component. The invention relates finally to a method for producing a ceramic component that can serve as a basis for an endoprosthesis component according to the invention. To achieve the desired roughness of the surface, the ceramic component is presintered at a temperature of between 880℃ and 980℃ and is then treated with a blasting material.本發明係與一種以一陶瓷材料所形成之內膺復物組件有關,其中該陶瓷材料係部份地以一鈦合金來塗覆。該內膺復物組件之未塗覆表面部分係被設計以作為與另一內膺復物組件互相作用之滑動表面。該內膺復物組件之一經塗覆表面部分係被設計以與一骨頭形成連結。依據本發明,該陶瓷材料之與該塗覆物形成一界面的部分,係具有一介於2.5μm和7μm之間的粗糙度Ra。其等會在該塗覆物與該陶瓷材料之間形成穩固的連結作用。本發明進一步係與一種用於生產此一內膺復物組件的方法有關。最後,本發明係與一種用於生產一陶瓷組件的方法有關,其能夠被用來作為一依據本發明之內膺復物組件的基礎。為了要達成所需之表面粗糙度,該陶瓷組件係在一介於880℃和980℃之間的溫度下加以預先燒結,然後以一沖刷材料來加以處理。1‧‧‧第一接觸板2‧‧‧第二接觸板3‧‧‧滑動表面4,5‧‧‧凸緣6‧‧‧第一椎體7‧‧‧第二椎體8‧‧‧界面9‧‧‧陶瓷材料10‧‧‧鈦合金塗覆物12‧‧‧突起13‧‧‧表面區域
