THE STRIBECK CURVE AND LUBRICATION CONDITIONS OF METALLIC AND POLYMERIC MATERIALS [PDF]
Journal of the Egyptian Society of Tribology, 2013 The present work discusses the selection of metallic and polymeric materials to be used as bearings in water lubricated condition. The study depends on using Stribeck curve to compare the friction performance of metallic materials (aluminium, bronze and ...

Lubrication in sliding and squeezing
, 2023 This thesis takes a deep look into the fundamentals of lubrication; the process in which the friction between two surfaces is reduced by adding a little bit of fluid in between, named the ‘lubricant’. The goal of this thesis is to improve our understanding of some relatively simple configurations, with the idea that it can serve as a proper foundation ...

Reduced Sliding Friction of Lubricant-Impregnated Catheters
ACS OmegaDuring urethral catheterization, sliding friction can cause discomfort and even hemorrhaging. In this report, we use a lubricant-impregnated polydimethylsiloxane coating to reduce the sliding friction of a catheter. Using a pig urethra attached to a microforce testing system, we found that a lubricant-impregnated catheter reduces the sliding friction ...

Lubrication characteristics of nanostripe-inducing structures under high contact pressure
Journal of Advanced Mechanical Design, Systems, and ManufacturingSurface texturing has been widely used to improve lubrication performance under oil-lubricated conditions; however, its effectiveness is generally limited to low contact pressures, and extreme-pressure (EP) additives are typically required under severe ...
