Studies of the Adhesive Component of Friction in Hip Joint Endoprostheses

We present here an analysis of the friction components in friction pairs of hip joint endoprostheses in conditions of dry friction and biological media. The tribological pairs studied were found to have different behavioral characteristics depending on the external loading and the “hardness” of the kinematic unit itself. The lowest levels of the adhesion component of the coefficient of friction were seen in ceramic−ceramic friction pairs.
