Effect of Artificial Aging on the Roughness and Microhardness of Sealed Composites
(Wiley-Blackwell, 2010-01-01)
Statement of the Problem:The application of surface sealant could improve the surface quality and success of composite restorations; however, it is important to assess the behavior of this material when subjected to aging ...
The hydrophobicity and roughness of a nasoenteral tube surface influences the adhesion of a multi-drug resistant strain of Staphylococcus Aureus
(Brazilian Journal of Microbiology, 2017)
Surface roughness and hardness of a composite resin: influence of finishing and polishing and immersion methods
(Universidade Federal de São Carlos (UFSCar), Dept Engenharia Materials, 2010-07-01)
This study evaluated the finishing and polishing effect on the surface roughness and hardness of the Filtek Supreme XT, in fluoride solutions. Specimens were prepared (n = 140) with half of the samples finished and polished ...
A DOE based approach for the design of RBF artificial neural networks applied to prediction of surface roughness in AISI 52100 hardened Steel turning
(Abcm Brazilian Soc Mechanical Sciences & Engineering, 2010-12-01)
The use of artificial neural networks for prediction in hard turning has received considerable attention in literature. An often quoted drawback of ANNs is the lack of a systematic way for the design of high performance ...
Effect of airborne particle abrasion protocols on surface topography of Y-TZP ceramic
(2012-04-01)
This study aimed to evaluate Y-TZP surface after different airborne particle abrasion protocols. Seventy-six Y-TZP ceramic blocks (5×4×4) mm3 were sintered and polished. Specimens were randomly divided into 19 groups (n=4) ...
Rugosidade superficial de ligas com alto conteúdo de cobre, em função do aquecimento acima da temperatura de fusão.
(1990-12-01)
Being the surface roughness a fundamental property in the fit of the castings, it was determined the roughness of 5 high-copper casting alloys, according to the heating over their melting temperature. That way, the specimens ...
Estudo comparativo do desempenho de rebolos com grãos superabrasivos e convencionais
(2001-07-01)
Grinding is a precision machining process which is widely used in the manufacture of components requiring fine tolerances and smooth surfaces. There are several imput parameters (cutting conditions, cutting fluid and ...
Atmospheric plasma treatment of carbon fibers for enhancement of their adhesion properties
(2013-01-18)
Plasma processing of carbon fibers (CFs) is aimed to provide better contact and adhesion between individual plies without decrease in the CF mechanical resistance. This paper deals with surface modification of CFs by an ...
