“…(1) The loops of the CH group (Figure a) exhibited closed elliptical shapes of all cycles. This result indicated that only a microslip occurred at the contact edge, while the imposed load and angular amplitude were greatly accommodated by the elastic‐plasticity deformation of the contact zone . In brief, the torsional fretting state of the CH group was in PSR.…”

“…The final friction torques in the PSR (CH group) was significantly lower than those in the GSR (PBS, HA, CS groups). In addition, this current test also achieved the results similar to the previous studies that the friction T of the test contact zone would rise with the increase of the angular displacement amplitude and normal load (Figure b and c) …”

“…Summarised from the previous studies, a physical model of cartilage surface damage (Figure ) is drawn to help explain the worn surface of the condylar cartilage in this test. (1) When the torsional fretting runs in the PSR, the wear scars can be marked out in the three zones from the contact edge to the centre.…”

“…The lubricating effect of the test solutions was discussed by the kinetic behaviours of condylar cartilage in the fretting wear test, which was based on friction torque (T) versus angular displacement amplitude curve (T-θ curve). [20][21][22] The torsional fretting states of tests could be defined according to the different shapes of T-θ curves. An elliptical shape of the T-θ curve presents that the torsional fretting of the test run in partial slip regime (PSR), in which there is a sticking zone in the centre of the worn surface and only a microslip occurred at the contact edge.…”

The aim of this study is to investigate the lubrication of hyaluronic acid (HA) and chondroitin sulfate (CS) on the condylar cartilage of the temporomandibular joint. The wear behaviour of bovine condyle cartilage was explored against a zirconia ball with different lubrications under torsional fretting mode. The worn cartilage morphologies were observed using scanning electron microscopy and hemotoxylin and eosin staining. The results indicated that HA or CS could significantly lower the friction torque and dissipated energy of fretting interface and reduce the damage of the articular cartilage surface compared to the control (phosphate-buffered saline). The mixture (HA and CS) could provide better protection for the cartilage layer. Absence of good lubrication in overloading torsional fretting process caused excessive cartilage wear. High concentration and high molecular weight HA or CS acted as good boundary lubricants, and the lubrication effect of their mixture was better due to their synergistic function. Figure 8.

Inspired by the cartilage-bone structure in natural joints, soft-hard integrated materials have received extensive attention, which are the most promising candidates for artificial joints due to their combination of excellent load-bearing properties and lubricating properties. The latest progress showed that the combination of hydrogel and titanium alloy can realize a bionic natural joint lubrication system on the surface of titanium alloy. However, obtaining a tough interface between the hydrogel (soft and wet) and the titanium substrate (hard and dry) is still a great challenge. Here, we designed a “soft (hydrogel)-hard (Ti6Al4V)” integrated material with outstanding combination, which simulates the structure and function of cartilage-bone in the natural joint. The load-bearing properties, binding performance, and tribological behaviors for different forms of the soft-hard integrated materials were investigated. The results showed that the hydrogel layer and Ti6Al4V substrate possess ultra-high interfacial toughness (3,900 J/m2). In addition, the combination of the hydrogel layer and Ti6Al4V substrate provided a good lubrication system to endow the “soft (hydrogel)-hard (Ti6Al4V)” integrated material with high load-bearing and excellent tribological properties. Therefore, this study provided an effective strategy for prolonging the service life of Ti6Al4V in the biomedical field.
