Microestrutura e propriedades tribológicas de aços austeníticos Fe-Cr-Ni-Mo sinterizados com adição de itria e boro
(2016-10-06)
Austenitic stainless steel materials are widely used in systems that require high
oxidation resistance and corrosion resistance. However, in contact with other surfaces,
these materials show a high coefficient of friction ...
Avaliação química, microestrutural e tribológica de filmes finos de TiCxNy produzidos por arco catódico para aplicações decorativas
(2016-11-24)
The deposition of thin films can be employed to modify and/or functionalize the properties of a material’s surface, improving wear resistance (tribological properties) or changing the resistivity (electrical properties). ...
Avaliação de óleo vegetal natural e epoxidado em composições elastoméricas para banda de rodagem
(2017-07-05)
The incorporation of vegetable oils into the development of tread rubber formulation has been one of the alternatives to reduce the use of oil with high contents of aromatic polycyclics. Many studies suggest the substitution ...
