Research progress of cartilage lubrication and biomimetic cartilage lubrication materials

Frontiers in Bioengineering and Biotechnology, 2022
Human joints move thousands of times a day. The articular cartilage plays a vital role in joints’ protection. If there is dysfunction in cartilage lubrication, cartilage cannot maintain its normal function.

THE MECHANISM OF LUBRICATION [PDF]

Journal of the Institute of Brewing, 1922
<div class="htmlview paragraph">The authors state that the coefficient of friction between two rubbing surfaces is influenced by a very large number of variables, the most important being, in the case of an oiled journal, the nature and the shape of the surfaces, their smoothness, the clearance between the journal and the bearing, the viscosity ...
