Avaliação do teor dos aditivos estabilizantes e das propriedades mecânicas em compostos elastoméricos para lateral de pneu de passeio submetidos ao envelhecimento natural e acelerado
(2015-02-11)
This study aims at analysing the ideal rate of two stabilizers in elastomeric compounds, used in tires that require a long-term performance, submitted to different kinds of aging. The resistance to the aging can be achieved ...
Processamento reativo de nanocompósitos iPP-POSS
(2015-10-06)
The interaction modes of polyhedral oligomeric silsesquioxane (POSS) of closed cages with distinct functional groups were evaluated on isotactic polypropylene (iPP) nanostructuration via reactive processing. POSS were ...
Avaliação físico-química e mecânica de zircônia nitretada a plasma
(2015-05-11)
This paper presents the nitriding experimental investigation of partially yttria stabilized zirconia (3 mol%), in particular, plasma generated by radiofrequency (RF), using two distinct methods: i) plasma nitriding, by ...
Estudo morfológico de uma blenda de I-PP e EPDM com argila
(2015-10-07)
In this work were investigated the morphological, themal and rheological properties of a isotactic polypropylene/ethylene-propylene-diene terpolymer rubber/nanoclay Cloisite 15A composite, prepared by mixed melt and submitted ...
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 ...
Deposição e caracterização de filmes finos de nitreto de titânio para aplicações decorativas
(2015-02-11)
This work studies the deposition of titanium nitride (TiN) thin films on stainless steel AISI 304 substrate for decorative applications. The films studied here are composed of a layer of Ti working as an interlayer between ...
Desenvolvimento e caracterização de compósitos sanduíche para isolamento térmico
(2014-05-29)
A sandwich panel consists essentially of two face sheets and may even have metal reinforcements and a core formed, usually by a cellular polymer. The faces of this type of panel may be joined by a structural adhesive or ...
