Dependence of nanoscale friction and adhesion properties of articular cartilage on contact load.
Boundary lubrication of articular cartilage by conformal, molecularly thin films reduces friction and adhesion between asperities at the cartilage-cartilage contact interface when the contact conditions are not conducive to fluid film lubrication. In this study, the nanoscale friction and adhesion properties of articular cartilage from typical load-bearing and non-load-bearing joint regions wer...
متن کاملSuperficial Zone Extracellular Matrix Extracts Enhance Boundary Lubrication of Self-Assembled Articular Cartilage.
OBJECTIVE Previous work has shown that increasing the production of boundary lubricant, superficial zone protein (SZP), did not reduce the friction coefficient of self-assembled articular cartilage constructs and was possibly due to poor retention of the lubricant. The aim of this investigation was to reduce the friction coefficient of self-assembled articular cartilage constructs through enhan...

متن کاملTribological behavior of sputter-deposited MoSX/Ni coatings
AbstractSputtered MoS2 coatings have been mostly used as a solid lubricant. In this investigation, MoSx/Ni composite coatings with Ni contents varying from 0 to 22 % were deposited onto steel substrate using a DC magnetron sputter process. The MoS2/Ni ratio in the coatings was controlled by sputtering the composite targets. The composition, microstructure, and mechanical properties of the...
متن کاملGemini Interfaces in Aqueous Lubrication with Hydrogels
The sliding interfaces found in the body— within the eyes, the digestive system, and the articulating joints, for example—are soft and permeable yet extremely robust, possessing low friction. The common elements among these systems are hydrophilic biopolymer networks that provide physical surfaces, elasticity, and fluid permeability. Stiff, impermeable probes are traditionally used to assess th...
