The friction phenomenon still does not have an understanding in fundamental terms. Such understanding would help clarifying the frictional energy dissipation during the interaction between atoms of two or more surfaces ...

The aim of the present work is to explore the production, dispersion and consolidation of zirconia (zirconium oxide – ZrO2), in its hydrous form, obtained from zirconium tungstate (ZrW2O8) in alkaline medium using temperatures ...

The usage of elastomeric materials for pipeline coating realizes a technic to protect the metallic materials, mainly against abrasion wear. The rubber layer must be sufficiently resistant to friction caused by the passage ...
