“…In addition to having similar mechanical properties, PVA hydrogels have a high water content resulting in a low surface friction resistance and low interfacial energy with water or biological fluids [35], thus these materials canmimic human soft tissues. An important advantage of PVA is the possibility to plan/design its properties by suitable selection of the ratio of hydrogel components, for example by changing the PVA and/or crosslinking agent concentration [36][37][38]. In this study, based on the work of Watler et al [36], 10 wt% of PVA was chemically cross-linked using glutaraldehyde in the presence of magnesium chloride.…”

The friction behaviour of new chitosan derivative coatings obtained by chemical modification of chitosan with fatty acids (linoleic and dilinoleic acid) has been investigated in order to explore their potential as endovascular catheter coatings and to benchmark them against commercially available coatings used in endovascular catheter applications. An in vitro tribological system was developed that was intended to represent to a limited extent the in vivo tribological conditions of a typical endovascular catheterization procedure. Continuous reciprocating sliding tests were carried out with uncoated and coated polymer specimens. The results showed that all of the coatings tested decreased the coefficient of friction compared to the uncoated polymer. Compared to a neat chitosan coating, the chitosan derivative coatings showed a clear reduction in the coefficient of friction to levels similar to those of the commercially-available coatings. A comparison between the friction results and contact angle measurements carried out on the coatings indicated that a range of contact angle values exists for which the friction coefficient is at a minimum. The reason for this is unclear and further studies are required in order to confirm and investigate the trend, especially within the context of hydrophilic lubricious coating development.

“…The effects of PVA factors on the friction properties are particularly fundamental to develop a soft tissue model with a proper characteristic for surgical training. The authors have investigated the friction properties of several kinds of PVA-Hs and have showed variations due to the PVA parameters [21]. In the present study, friction tests were carried out using the same experimental system as that of the previous study under redesigned test conditions for the further investigations of the effects of PVA parameters.…”

In this study, the friction of eight kinds of poly(vinyl alcohol) hydrogel (PVA-H) samples has been studied under various load and velocity conditions to elucidate the effects of PVA factors such as the degree of polymerization (DP) and the saponification value (SV) on the tribological behavior of PVA-H. Results showed the variations of the friction properties due to the PVA factors in the two friction conditions found for the hydrogels: elastic friction and hydrodynamic lubrication. In the elastic friction, the larger frictions were induced by the higher values of DP and SV. In the hydrodynamic lubrication, on the other hand, PVA-Hs with lower SV showed larger friction. The results can then be used to adjust the parameters of PVA-H in order to get given friction properties, for instance for the friction between catheter or scalpel and PVA-H, which can be used as a biomodel material of artery or oral mucosa, for the training of surgeons.

“…The low cost, environmental friendliness, and the excellent cooling effect of water have attracted many researchers to investigate the tribological performance of different materials under water lubrication [5][6][7][8][9][10][11][12][13]. Lei et al evaluated the tribological behavior of micro and nano-crystalline diamond films in water lubricating conditions [5].…”

Mamada et al [10] systematically studied the friction properties of polyvinyl alcohol-hydrogel(PVA-H)/steel ball contact under water lubrication conditions. Wang et al [11][12][13] comparatively investigated the tribological behaviors of several polymers under the lubrication of sea water.…”

Water Pool Behaviors of Water Lubricating for Glass/Steel Point Contact

Abstract:The behavior of pools of water for lubrication under a point of contact between a glass disk and a steel ball is studied here, employing a home-built apparatus. A deformed water pool is found to form around the contact region under different rolling speeds. To investigate the effect of rolling speed on the water pool, two parameters (advancing angle and receding angle) are introduced to describe the shape of the water pool. Two distinct glass surfaces, namely a smooth surface and a microgrooved surface, are observed. In the case of the smooth surface, the advancing/receding angle of the water pool significantly decreases with increasing rolling speed before the rolling speed reaches a critical value (80 mm/s). At speeds higher than 80 mm/s, the water pool is in a stable state and the advancing/receding angle remains steady. In the case of the microgrooved surface, the influence of the microgroove on water lubricating flow disappears when the rolling speed reaches a critical value (1030 mm/s).
