This article provides an overview of the fundamentals of tribology. It describes the advantages, disadvantages, and applications of pin-on-disk method, which is the most commonly used configuration for testing biomaterials and for the reproducible measurement of friction and wear. The article illustrates practical tribocorrosion setup that allows the user to perform wear tests in corrosive environments under well-defined electrochemical conditions and at controlled temperature. It describes the effect of changes in electrical contact resistance on tribological mode. The article discusses various in vivo environmental conditions in tribological tests. Some typical examples of biomaterials testing are also provided.
