“…Moreover, the phenomenon of hydration and dehydration of the articular cartilage had signi cant e ects on the declining trend of friction [30]. In this study, there was no single trend of the coe cient of friction with the stainless steel ball against the arti cial cartilage.…”

e mechanical and tribological properties of polyvinyl alcohol hydrogel as an arti cial cartilage were studied under water and bovine serum albumin-lubricated sliding conditions. e frictional properties of the polyvinyl alcohol hydrogel were investigated via reciprocating frictional tests. e e ect of surface mechanical deformation on the tribological properties of the polyvinyl alcohol hydrogel as an arti cial cartilage was studied by concurrently recording the z-axis displacement and friction coe cient time. ree di erent factors were chosen including load, speed, and lubrication. e results showed that the albumin solution could reverse the trend in the coe cient of friction in tests at di erent loading levels. ere was no improvement in the friction condition in albumin at low speeds. However, when the speed was increased to 2 Hz, the coe cient of friction was signi cantly reduced. Wear testing was also conducted, and wear tracks were found on the sample surface. e results also showed that even though the surface deformation could recover as the water phase of the porous structure recovered, the coe cient of friction continued to increase simultaneously. is relationship between mechanical and frictional tests indicated that biphasic lubrication e ects may not be the only dominant factor underlying the excellent friction properties of polyvinyl alcohol hydrogel.

“…As the time going, more interstitial water within the porous structure of hydrogels was squeezed out away the contact area, while there was insufficient time for the non-contact area to rehydration. Thus the proportion of load supported by the solid phase was continuously increased, which enlarged the solid-to-solid contact and increased the friction coefficient, and then reached to a relatively stable level [23,53]. As shown in Figure 8, the friction coefficient of the pure PVA hydrogel increased rapidly, and the samples were worn out within 800 s. After blended with PVP, the hydrogel was kept relatively low level of friction during the entire friction tests, which was due to the higher hydrophilcity of PVP and the resulting improved lubricity.…”

Abstract. Poly (vinyl alcohol)/poly (vinyl pyrrolidone) (PVA/PVP) hydrogels with various polymerization degrees of PVA were synthesized by a repeated freezing-thawing method. The influence of polymerization degree on microstructure, water content, friction coefficient, compressive fatigue and recovery properties of PVA/PVP hydrogels were investigated. The results showed that higher polymerization degree resulted in larger compressive modulus and lower friction coefficient. The fatigue behaviors of PVA/PVP hydrogels were evaluated under sinusoidal compressive loading from 200 to 800 N at 5 Hz for up to 50 000 cycles. The unconfined uniaxial compressive tests of PVA/PVP hydrogels were performed before and after fatigue test. During the fatigue test, the height of the hydrogel rapidly decreased at first and gradually became stable with loading cycles. The compressive tangent modulus measured 0 h after fatigue was significantly larger than the values obtained before test, and then the modulus recovered to its original level for 48 h after test. However, the geometry of hydrogels could not return to the original level due to the creep effects. PVA/PVP hydrogels prepared with lower polymerization degree showed better recovery capability than that prepared with high polymerization degree.

“…As previous metal on cartilage indentation tests have demonstrated: increased contact stress increases the deformation of articular cartilage (Forster and Fisher, 1996;Pawaskar et a/., 2007;Katta et a/., 2008b;McCann et a/., 2008).…”
