Surface Friction of Polymer Gel

Kobunshi, 2002
Abstract The sliding friction of various kinds of hydrogels on solid surfaces or on gels has been studied and it was found that the frictional behaviors of the hydrogels do not conform to Amonton's law F = μW , which well describes the friction of solids.

Utilization of Magnetic Fraction Isolated from Steel Furnace Slag as a Mild Abrasive in Formulation of Cu-Free Friction Composites

Lubricants
Magnetic fraction isolated from steel furnace slag was tested as a component of Cu-free friction composites. The friction–wear performance and production of wear particles during their testing using a pin-on-disc tester against a cast iron disc were ...

Design method of surface texture for controlling friction characteristics

Nihon Kikai Gakkai ronbunshu, 2019
In this research, we propose a numerical method to design surface texture with the desired friction characteristics, which are arbitrarily given according to the design purpose. The surface texture is parameterized, and the parameters are determined with

Efficiency of polymer materials in highly loaded systems in the aviation industry

Aviation, 2023
The static coefficient of friction was calculated on an inclined plane tribological stand. Different specimens and masses loading the system were used during the experiment. Surface-to-surface contact was tested in a pin-on-plate setup.

Criteria for Evaluating the Tribological Effectiveness of 3D Roughness on Friction Surfaces

Lubricants
A new technique for finishing the surfaces of friction pairs has been proposed, which, in combination with the original test method, has shown a significant influence of the initial roughness configuration (surface texture) on friction and wear.
