Abstract

Abstract Translated from German Um bei einem Verfahren zum Aufbringen einer Schutzschicht aus TiO₂, Al₂O₃, ZrO₂ oder Cr₂O₃ auf Gleitflächen von Gelenkendoprothesen aus Titan oder Titanlegierungen eine besonders kompakte und dicke Schutzschicht erzeugen zu können, wird vorgeschlagen, daß man die zu beschichtenden Gleitflächen in einem Vakuum anordnet und auf ihnen die pulverförmigen, in einem heißen, ionisierten Gasstrom (Plasma) aufgeheizten und dadruch an- oder aufgeschmolzene Beschich­tungsmaterialien ablagert. In order to be able to produce a particularly compact and thick protective layer in a method for applying a protective layer made of TiO₂, Al₂O₃, ZrO₂ or Cr₂O₃ on sliding surfaces of joint endoprostheses made of titanium or titanium alloys, it is proposed that the sliding surfaces to be coated be arranged in a vacuum and on them deposits the powdery coating materials, heated in a hot, ionized gas stream (plasma) and thus melted or melted on.
