THE ANALYSIS OF THE TRIBOLOGICAL PROCESSES OCCURRING IN THE SOCKET-AND-BALL FRICTION PAIR OF A HIP JOINT ENDOPROSTHESIS

Journal Title: Tribologia - Year 2015, Vol 264, Issue 6

Abstract

The paper presents a hip joint as an ideal system. The causes of the damage to a natural human hip joint and the ways of restoring its lost functions along with hip joint alloplasty are discussed. In the research part of this paper, based on in vitro study, the reasons for the loss of artificial hip joint durability are described. The subject of the research was the socket-andball friction pair, making the elements of a hip joint endoprosthesis. The surfaces of the analysed samples were prepared in accordance with the guidelines of the standards. The tribological tests were conducted in the environment of Ringer's solution. The examination of the surface topography before and after tribological tests was carried out with three units: a coordinate measurement machine, white light interferometry, and a scanning electron microscope. The results were analysed in terms of tribological processes (wear mechanisms) occurring in the friction pair consisting of the polymer socket and the metal head of a hip joint endoprosthesis.
