Tiny particles are all over around us and sometimes they may create problems. This is especially of concern with metal particles formed due to wear in man-made engineering devices. Particles formed in car disk brakes […]

Bio-tribological Advancements in Modular Interface of a Joint Implant

30.01.2024

Introduction In daily activities, articulating interfaces undergo three-dimensional dynamic motion and loading, transmitting frictional forces to modular interfaces, causing fretting wear and corrosion. This phenomenon is observed in various artificial joints, including hips, knees, shoulders, [...]
