Comportamento do atrito por indentação em nanoescala do aço-carbono AISI 1045 nitretado e pós-oxidado com diferentes nanocamadas de magnetita
(2016-05-18)
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 ...
Produção, dispersão e consolidação de zircônia obtida a partir do tungstato de zircônio
(2016-05-11)
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 ...
Composições elastoméricas reforçadas com fibras para o revestimento de superfícies metálicas
(2023-02-15)
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 ...
