Tribology combines the studies of friction, wear and lubrication. In biomedical research, tribology is employed to understand naturally occurring motions between tissues and organs but also for artificially created boundaries between natural and implant surfaces.
In this case study, analysis instrumentation firm Anton Paar describes a rotational tribology setup that enables the investigation of cartilage under defined conditions both in oscillatory or rotational motion.
According to Anton Paar, this setup allows performing friction measurements over a broad range of sliding velocities and normal pressures.
Friction measurements were conducted using an MCR 102 rheometer equipped with TruStrain control and the Tack/Squeeze/Normal Force extension package.
A T-PTD 200 tribology system was mounted onto the rheometer by replacing the Peltier plate that is typically used for rheology.
In the sample holder of this tribology system, three osteochondral cylinders were placed as a sample set, and this sample set was probed simultaneously using a ½ inch glass sphere as tribological counterpart.
